overview
This  document  describes  how  to  use ASCII  text  communications  to  control  one  or  more  of  the 
following Wolf Cinema projectors from a remote location:DCX-500i

ConneCTIon  and  Use:  Once  you  have  connected  your  computer  to  either  the  Rs232  In  or 
Rs422 In port (depending on which standard is supported by your computer) or to the  eTheRneT 
port on a projector listed above, you can remotely access projector controls and image setups, 
issue commands or queries, and receive replies. Use these bi-directional\
 messages to:
Control multiple projectors
•	
Obtain a projector’s status report
•	
Monitor sequences of events
•	
Diagnose performance problems
•	
noTes: 1) Refer to the User’s Manual provided with the projector for all cable requirements and 
other  connection  details.  2)  Some  commands  are  operational  only  when  projector  is  powered 
up.
Understanding Message format
All  “remote  control”  information  passes  in  and  out  of  the  projector  as  a  simple  text  message 
consisting  of  a  three  letter  command  code  and  any  related  data.  Opening  and  closing  round 
brackets (parentheses) surround each message as shown below. Messages can be a command 
to  set	 a	projector	 parameter	 at	a	specific	 level,	such	as	changing	 to	a	certain	 channel.	 Or	the	
controller can  request information, such as what channel is currently in use—the projector then 
returns  the  data  in  a  reply  message.  Regardless  of  message  type  or  origin,  all  messages  use 
the same basic format and code as shown here.

Examples
Where  applicable,  a  message  may  expand  to  include  additional  parameters  of  related  details. 
And,  if  desired,  you  can  choose  to  include  optional  information  such  as  acknowledgements, 
checksums, and network addressing.
2.  Understanding 
Message format
1.  overview
Appendix	B	►	Serial	Communications 
						

							B-4
2.1  basic Message structurebasIC Message sTRUCTURe
The	following	 component	 fields	comprise	 a	standard	 ASCII	message.	 Optional	fields,	such	as	
extra  characters  for  special  modes,  restrictions  or  added  functionality,  are  shown  in  shaded 
areas.
sT aRT  anD  enD of  Message:  Every  message  begins  with  the  left  “(“character  and  ends 
with the right “)“ character. Note that if the start character is received before an end character of 
the previous message, the partial (previous) message is discarded. 
PREFIX CHARACTERS (OPTIONAL): For acknowledgement that the projector has responded, 
and/or to maximize message integrity, insert one or two special characters before the 3-character 
function code: 
  $ Acknowledgment. See 2.4, Maximizing Message Integrity 
  & Checksum. See 2.4, Maximizing Message Integrity
fUnCTIon CoDe:  The projector function you wish to work with, such as channel selection or 
gamma, is represented by a three-character ASCII code (A-Z, upper or lower case). This function 
code appears immediately after the leading “(“ that starts the message. In messages sent to the 
projector,	 a	space	 between	 the	function	 code	and	the	first	 parameter	 (or	special	 character)	 is	
optional. 
ReQUesT/RePl Y sYMbols:  If  the  controller  is  requesting  information  from  the  projector, 
a  “?”  question  mark  appears  directly  after  the  function  code.  If  the  projector  is  replying,  a  “!” 
exclamation  mark  appears  directly  after  the  function  code.  For  set  messages  to  the  projector, 
neither of these characters appear—the code is followed by the data i\
tself (see next). 
OTHER  SPECIAL  FUNCTIONS  (OPTIONAL):  To  add  functionality  to  the  current  message, 
include  one  or  more  of  the  following  special  characters  between  the  function  code  and  first 
parameter. If more than one (M SP), add in any order. 
  A Auto Mode adjustment (rare—for video standard selection only). See \
2.6, Other    
    Special Functions
  E Enable Control Inquiry. See 2.6, Other Special Functions 
  G Global Control Inquiry. See 2.6, Other Special Functions 
  H Return the Help text for a control. See 2.6, Other Special Functions 
  I Used as an index for controls containing many values. See 2.6, Other Spe\
cial    
    Functions 
  K Keypad emulation. See 2.6, Other Special Functions 
  L Return a list of options for ‘list’ controls. See2.6, Other Special Functions 
  M Find min/max adjustments (i.e., range). See 2.6, Other Special Functio\
ns 
  N Return the name of the control. See 2.6, Other Special Functions 
  S Adjust a specific source setup only. See 2.6, Other Special Functions 
  T Return the type of control (i.e. Slidebar etc.). See 2.6, Other Specia\
l Functions 
  P Adjust image in PIP window. See 2.6, Other Special Functions 
Da Ta:  The  value  for  a  given  projector  state,  such  as  “on”  or  “off”,  appears  in  ASCII-decimal 
format directly after the request/reply symbol. You can add an optional space after the symbol—
i.e., before the data—in a  set message, but data in  replies follow the “!” symbol without a space. 
Other details to remember about data: 
All	values	 returned	 by	the	 projector	 (reply	messages)	 have	a	fixed	 length	 of	either	 3	or	
•	
5  characters  regardless  of  the  actual  value—the  value  is  padded  with  leading  zeros  as 
necessary.
Data in set messages to the projector does not require padding with zero\
s.
•	
For any given parameter, data is always the same number of characters. E.g., the 
•	 shutter 
value, which is either “on” (1) or “off” (0) is always 3-digits: 001 or 000.
Appendix	B	►	Serial	Communications 
						

							B-5
Within  each  message,  multiple  parameters  of  data  must  be  separated  by  one  “
•	 space” 
character.
Data  pertaining  to  a  source  setup  other  than  the  current  source  setup  is  preceded  by:  the 
•	
letter “S”, the source setup number (i.e., channel), and a space. This is similar to an “extra” 
parameter P0. 
Text parameters such as channel names are enclosed in double quotes following the data, 
•	
as in “Name”.
TexT  P aRaMeTeRs:  Most  data  is  simply  a  numerical  value,  however  some  messages  also 
require  text.  For  example,  a  channel  naming  message  typically  includes  a  text-based  name 
after  the  channel  number—enclose  this  text  in  double  quotation  marks,  as  in  “Tilt  the  Wagon”. 
Use all characters as desired except for the following special characters shown in the left column 
below—these require a 2-character combination as shown:

Although you will send and read messages as strings of ASCII characters, the actual message 
travels as a sequence of bytes. Each character in this sequence requires 1 byte. See example 
below, which illustrates a “lamp limit is 2000 hours” reply from the pr\
ojector.

sent in a Message
Appendix	B	►	Serial	Communications 
						

							B-7
2.4  Maximizing Message IntegrityMaxIMIzIng Message InTegRITY
For additional reassurance and/or maximum message integrity, you can insert one or two special 
characters:
aCKnoWleDgMenTs:  If  you  want 
assurance  from  the  projector  (or  group 
of  projectors)  that  a  set  message  has 
been  processed,  request  this  simple 
acknowledgment  by  inserting  a  “$” 
just  after  the  start  code  “(“.  When  the 
projector  executes  the  required  action 
(such  as  a  source  switch,  for  example),  the  projector  will  send  a  “$”  (only)  back.  This  is  a 
quick	way	to	confirm	 success	 with	set  messages,  and  is  particularly  useful  with  long-distance 
communication  links  or  where  the  projectors  and/or  images  are  not  visible  from  the  controller. 
Acknowledgements	 can	also	 be	a	type	 of	flow	 control.	 Note	that	requesting	 an	acknowledgement	
serves  no  purpose  when  included  in  a  request  message,  since  the  acknowledgement  will  be 
redundant to the actual reply from the projector. However, if requested, the “$” acknowledgement 
from the projector will follow the reply. 
CheCKsUMs:  For maximum message integrity, add a checksum character “&” just after the “(“ 
as shown below. You must then also include the correct checksum total (0-255) just before the 
“)” end code. Make sure to add a space before the calculated checksum to separate it from the 
last data parameter:  (&con64 240)
The  checksum  is  the  low  byte  of  the  sum  of  the ASCII  values  of  all  characters  between  the  “(“ 
and the beginning of the checksum. Calculate the checksum for the above “set contrast to 64” 
command as follows: 
CheCKsUM exaMPle  = & + c + o + n + 6 + 4 + ‘space’
      = 26h+63h +6Fh +6Eh +36h +$34h +$20h
      = 01F0h
      = F0h when only the low byte is used
      = 240 
The	 projector	 collects	all	of	the	 message	 bytes	as	defined	 in	the	 first	 byte	 of	the	 message,	 then	
creates  its  own  checksum  value  for  comparison  with  the  checksum  included  in  the  controller’s 
message.  If  the  values  match,  the  message  is  considered  to  have  been  correctly  received—
otherwise the message is discarded. 
noTes:  1)  ‘h’  indicates  a  hex  number.  2)  If  a  “request”  message  has  a  checksum  so  will  the 
reply. 3) If using both “acknowledge” and “checksum”, either character can occur first.

2.5  Accessing Specific source setupsaCCessIng sPeCIfIC soURCe seTUPs
For ASCII  messages  described  in  this  document,  it  is  assumed  you  are  adjusting  the  current 
source	setup	(channel)	 rather	than	a	different	 specific	one.	However,	 for	several	 commands	
(for example, ASR,  Auto Source) you can direct the message to particular source setup. To do 
this, insert an “s” and a source# (such as “S5”) before the parameter value—the source setup 
number	 can	be	thought	 of	as	 a	“P0”	 parameter	 prior	to	the	 first	 parameter,	 and	can	be	preceded	
with an optional space. For example:
  (ASR S25 1)   = Turn Auto-Source on for source setup #25 
Use “S0” if your setting should be applied to all source setups (\
channels):
  (ASR S0 1)   = Turn Auto-Source on for all source setups 
The “S” source setup function cannot be used for parameters affecting the projector as a whole 
such as projector address. 
  Other Examples:
  (ASR 1)    = Turn ASR on for the current source setup
  (ASR? S5)   = What is the ASR status for source setup #5? 
  (ASR!S005 001)  = ASR is on for source setup #5
  (ASR? S7)  = What is the ASR status for source setup #7?
  (ERR 006 "ASR: Source does not exist")  = Source setup #7 does not exist
  (ASR?)    = What is the ASR status for current source setup?
  (ASR!000)  = ASR is off for current source setup
oTheR sPeCIal fUnCTIons
To add functionality to a message, include one or more of the following special characters directly 
after the start code “(“. If you add more than one, they can be i\
n any order. 
P aRaMeTeR  lIMITs:	For	 single-parameter	 projector	function	codes,	you	can	find	out	the	
current range of adjustment by adding the letter “ M” to your request message. For example: 
  (lPl?M)    What is the minimum and maximum lamp limit? 
  (lPl!M000 5000)   Minimum lamp limit = 0, maximum lamp limit = 5000. 
Ranges cannot be determined in this manner if the function has multiple parameters. Note also 
that  for  text-based  parameters,  the  “M”  values  represent  the  shortest  and  longest  text  strings 
possible. 
“aUT o” MoDe: For certain projector functions, you can add the letter “a” to your set message if 
you want software to choose the appropriate setting. A  reply with an “a” indicates that the choice 
was auto-selected. For example: 
 
(sTD  a

)   Set the video standard to the most appropriate option. 
  (sTD?)    What is the current video standard? 
  (sTD!a4)  The video standard was automatically set to option 4 (such as    
      PAL-M). 
Note  that  in  these  projectors,  auto  mode  is  supported  only  for  selecting  a  video  standard. 
Although other functions (such as Motion Filter) may offer an “Auto” choice in its list of options, 
a reply message from the projector will not include “A” to indicate that “Auto” it is selected—auto 
is simply an option chosen like any other. 
aDjUsTIng  a  PIP  IMage:  When  there  are  two  images  on  screen,  all  messages  affect  the 
primary image—that is, the larger “background” image. To direct a message to the PIP window 
instead, add the letter “P” to your set message. For example: 
  (Con P47)  In the PIP window, set contrast to 47. 
  (sTD? P)  What is the current video standard used in the PIP window? 
2.6  other special 
functions
Appendix	B	►	Serial	Communications 
						

							B-9
helP TexT:	To	have	 the	Help	 Text	for	a	specific	 command	 returned	as	a	reply	 from	the	projector,	
add the letter “h” to your request message. For example: 
  (Con?h)      What is the help text for the Contrast Control? 
  (Con! “The Contrast is crushed”)  Reply from the projector. 
global  InQUIRY:  Add the letter “g” in your  request	message	 to	find	 out	if	the	 control	 is	global.	
A reply of “001” is returned if the control is global. For example:\
 
  (bDR?g)  Is BDR a global control? 
  (bDR!001)  BDR is a global control. 
InDex V alUe: When a control uses indexes for multiple values, insert an “I” into your request 
message	to	fin	out	the	specific	value	of	the	index	parameter.	For	example:	
  (bRU? I22)	 What	is	the	value	for	White	Field	Uniformity	specified	by	index	22?	
  (bRU! 123)  The value is 123 for index 22.
aCCessIng  a lIsT:  For  a  control  with  a  list  of  available  options,  add  the  letter  “L”  to  your 
request message to get a reply of the available options in that list control in the order they appear 
in the menu. The reply message includes the following four parameters: 
P1=1, item selectable
P2=1, item displayable
P3=value of item
P4=text for item 
examples:
  (sTD?l)   What are the list options for the STD list control?
  (sTD!l001 001 00008 “auto”)
  (sTD!l001 001 00007 “nTs
C”)
  (s

TD!l001 001 00003 “nTsC4.43”)
  (sTD!l001 001 00000 “P al”)
  (sTD!l001 001 00004 “P al-M”)
  (sTD!l001 001 00005 “P al-C”)
  (sTD!l001 001 00006 “P al-60”)
  (sTD!l001 001 00002 “seCaM”)
  (sTD!l001 001 00009 “?”)
  (sTD!l111 “—enD—”) 
The	 end	of	the	 list	is	marked	 with	P1=111.	 You	can	also	 access	 the	text	 for	a	specific	 item	in	that	
list by adding the value of that item after the  l. For example: 
  (sTD?l4)  What is the text for item for in the Video Standard list? 
  (sTD!l001 001 00004 “P al-M”) 
ConTRol  naMe:	 To	find	 out	the	name	 of	the	 control	 you	are	using,	 add	the	letter	 “n” to your 
request message. If the control uses indexes for multiple values, insert the index number after 
the “n” to read the name of the index. For example: 
  (Con?n)  What is the name of the CON control?
  (Con! “Contrast”)
  (bRU?n2)  What is the name for index parameter 2 for BRU?
  (bRU! “left side, R”)
  (b
RU?n

6)  What is the name for index parameter 6 for BRU?
  (bRU! “Top left Corner, R”) 
ConTRol  TYPe:	To	find	 out	the	type	 of	control	 it	is	 that	 you	are	using,	 add	the	letter	 “T” to your 
request  message.  If  indexes  are  being  used  for  control  with  multiple  values,  insert  the  index 
parameter after the “T”	 to	find	 out	the	type	 of	control	 that	the	index	 is.	For	 some	 slide	bar	or	number	
controls, an additional parameter may be returned to specify the number of decimal places the 
control uses and if the control is to be displayed as a percentage (0=min and 100=max). If the 
reply message does not contain the letter “ T”, than this function is invalid for that control. 
Appendix	B	►	Serial	Communications 
						

							B-10
The parameters for control types are: 
0 = special format 5 = Text
1= slide bar    6 = “Reserved Control”
2 = Checkbox    7 = Date
3 = list      8 = Time
4 = number    9 = IP (dotted quad) 
examples:
  (sTD?T)     What type of control is STD? 
  (sTD! T003)     STD is a List. 
  (Con?T)     What type of control is CON? 
  (Con! T001 %000)   CON is a slidebar that is currently at 0%. 
  (ebb?T8)     What type of control is index parameter 8 of EBB? 
  (ebb! T004 237)    EBB is a number control and it’s current value is 237. 
enable  InQUIRY:  Add  the  letter  “e”  in  your  request	message	 to	find	 out	if	the	 control	 is	
enabled in the current context. A reply of “001” is returned if enabled. If the control has and index 
for multiple values, that index should be used to read the enable status\
. 
  (sTD?e)  Is STD enabled in the current context?
  (sTe!e001)   STD is enabled. 
KeYP aD eMUla TIon: Add  the  letter  “K”  in  your  set  message  to  change  to  a  quick  “keypad 
mode”  within  the  message.  The  next  value  in  the  message  now  represents  the  adjustment  of 
the parameter. 
  K0    Stop the adjustment
  K1    Toggle check box state
  K2    Start decreasing a value, or moving the current image left/up
  K3    Start increasing a value, or moving the image right/down 
examples:
  (lho K2)  Start moving the image left
  (lho K0)  Stop moving the image horizontally
  (fRz K1)  Freeze or unfreeze the image on the active window 
Keypad emulation is required in APR, FCS, LHO, LVO and ZOM messages set messages. 
floW ConTRol
Normally  messages  can  be  sent  to  the  projector  before  processing  of  earlier  messages  is 
complete—the projector will just store messages in a buffer until ready to process. However, if 
a series of messages is sent it is possible that the projector may not be able to process them as 
fast as they arrive and the buffer will become full. If this happens, the projector will send the 13h 
(Xoff) code to instruct the controller (or any devices preparing to transmit) to cease transmission. 
At this point, the controller must respond immediately and send no more than 10 extra characters 
or they may be lost (i.e., the projector is able to accommodate the receipt of up to 10 more bytes 
after it sends 13h [Xoff]). When the buffer is once again available, the projector will send a 11h 
(Xon) command to resume transmission. 
noTe:  Xon and Xoff controls apply to both directions  of communication. The projector  will  not 
send more than 3 characters after it has received a 13h (Xoff) code. 
floW  ConTRol   WITh  “aCKnoWleDge”:  If  the  controller  waits  for  each  message  to  be 
acknowledged before sending the next and the controller does not send a message that is longer 
than 20 characters, then the projector will never send an Xoff and the controller does not have 
to handle them. If the projector has not received an Xon after receiving an Xoff code, after a time 
out it will assume that the Xon was lost and start transmitting again. If the controller has received 
an  Xoff  and  no  Xon  within  a  reasonable  time,  it  can  assume  that  the  Xon  was  lost. These  two 
time	outs	are	projector-specific	and	are	in	the	range	of	3s-60s.

This  section  lists  all  ASCII  message  codes  for  controlling  the  projectors  listed  on  page  3.  To 
fully understand how an adjustment works or what it does in the projector and/or image, always 
consult the User’s Manual provided with your projector. 
general notes to Remember:
When	 a	parameter	 for	a	specific	 source	setup	is	accessed	 (see	2.5	Accessing	 Specific	
•	
Source Setups) an “S” is inserted between the command code (spac\
e) and P1 (no space
The smallest increment for adjusting any parameter is always 1.
•	
For some controls (Contrast, e.g.), the value displayed on the screen is a percentage while 
•	
the  actual  hardware  has  a  range  of  0-255.  In  these  cases,  remember  that  ASCII  values 
are correlations to the screen values, and will not match numerically (ASCII 0 = 0%, ASCII 
128=50.2%, etc.). 
aCe   aUTo ColoR enable
Use	 to	automatically	 project	a	specific	 color	or	colors	 when	working	 with	controls	 such	as	Input	
Levels, Odd Pixel Adjustment, Color Temp Adjust adjustments, etc. 
aDR  PRojeCT oR nUMbeR
ADR	 identifies	 or	sets	 the	projector’s	 assigned	number	(0-999)	so	that	 it	can	 be	controlled	
separately within a group of linked projectors. To change the Ethernet IP address via ASCII, see 
XIP. 
agC   aUToMa TIC gaIn ConTRol
AGC automatically tracks the sync amplitude of the incoming signal. 
aIl   aUT o InPUT leVels
AIL allows the projector to continuously monitor the input signal levels and make adjustments as 
necessary to prevent crushing. 
aPj   aCTIVe PRojeCT oR
Use	 APJ	 to	temporarily	 disable	(0)	or	enable	 (1)	the	 IR	and	 Wired	 Keypad	 inputs	to	a	specific	
projector in a network of projectors. APJ is essentially the same as using the 
Proj  key, and is 
best understood as a way of changing a projector’s listening status even though 
 and Proj 
still work.  noTes: 1) APJ does not affect the built-in keypad.  2) An APJ to disable the keypad 
does not change the state of the Communications menu checkboxes for Front IR, Rear IR, Wired 
Keypad—these  will  remain  checked  (on).  3)  The  keypads  revert  to  “enabled”  after  a  power-
down, or if the projector is unplugged and plugged in again. 
aPR  IRIs
Used  APR  to  adjust  the  Iris  size  from  0-9.  Raise  to  improve  contrast,  lower  to  improve 
brightness. 
 
  (APR K2) - start increasing the aperture size (higher brightness)
  (APR K3) - start decreasing the aperture size (higher contrast)
  (APR K0) - stop changing the aperture size 
To “nudge” the aperture size, script in a delay between (APR K3) and (APR K0). Depending on 
your	application,	a	delay	of	at	least	20-30	milliseconds	may	be	sufficient.
