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...

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,...

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...

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”...

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?...

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...
