6.2 Printer Setup
The RS-232 comm port is capable of outputing tension data. All the weight modes the 
Dyna-Link can measure are available in user formatted form. The control mode 
program is what causes the  Dyna-Link 2 to print. 
• USER – the assigned F-Key is pressed, then one transmission of the selected  stri ng 

type is output. 
• On Load – when the tension on the link is stable, one transmission will output,  then  t

he tension must return to zero to enable another print to output. 
• Continuous – program the interval in seconds up to 65,535 seconds. 
Setting the interval to 0 will set an interval as fast as the system can go. To disable 
pri nting

, simply don’t program an F-Key to print and set the control to “USER” or 
turn the control mode to “OFF.”

Table 6-1. Standard Print Strings
In the string number entry screen, you can enter combinations of the standard print 
strings. For example, t
 o get a NET GROSS TARE printout with a space between 
records, simply enter “2349.”
Using SCCMP application (ScaleCore configuration management program),  custom
  
output strings are possible. See the ScCMP programming guide for details. 
NoteScCMP programming can be found  on the CD included with the 
product or can be downloaded from the MSI website.
The serial output is configured as 9600 baud, Xon/Xoff handshaking, no hardware 
handshaking, 1 stop bit, no parity. Other baud rates are possible by special order only.

4) The current print mode format number is displayed.
5)
Set up a print format with one or
more digits representing the data
type required for the print output.
In this example, we’ll set the print format
for a net, gross, tare output with a
carriage return/line feed between each print output.  The number entry required
will be 2349. The 2 is for net weight,
the 3 for gross weight, the 4 for tare
weight, and the 9 inserts a space beforethe next print output.
6) Using the  F2 Key, scroll through
the digits until the desired digit
is shown, then press F1 to enter
the digit value. Repeat for the
remaining digits.
7) When the entire number is displayed press  F1. The next
item in the print menu appears,
Cntrl.
8) Press F1 to enter the print
control menu. The last set control
mode will appear.
9) To change the print control mode, press F2.
In this example, we’ll set the print control
mode to continuous.
10) Press  F2 key until the desired
print control mode is shown.
11) When the desired print mode is shown, push F1 to save. The
next print setup item, rAte
appears. If you have set

6.3 Comm Port Hardware
The Dyna-Link 2  RS-232 comm port is used for  software updates, connecting to a 
remote display, and for connecting to any RS-232 device.
Table 6-2. Comm Port Hardware
ConnectorM12 industrial IP67 rated. An adapter cable (P/N 503363) is 
re
quired to connect the 
Dyna-Link 2 to a computer. This 
adapter cable converts the 
Dyna-Link 2 connector to a 
standard D9 serial connector.
Data Configuration The data output is fixed at 8-1-N.
Baud Rate Programmable for 300 to 230.4k baud in eight steps. The 
bootloader for updating software

 is always 38.4k baud.
Handshaking No hardware handshaking is  supported XON/XOFF softwar e
  
handshaking is always on. 
It may be necessary to disconnect the shield drain wire at the D-9 
connector frame to prevent ground  loops. Ground loops can cause 
unstable readings. In extreme cases  it may be necessary to use an 
opto-isolated RS-232 interface.Note

6.4 802.15.4 RF Network Setup
When equipped with the 802.15.4 option, the  Dyna-Link 2 can connect with an 
MSI-8000  Remote Display or 
 an 802.15.4 modem. The unit uses three numbers to 
connect to an 802.15.4 piconet:
1. ScaleCore ID – uniquely identifies each ScaleCore device in a  piconet. 
 It has a 
range of 0-254 and must not be duplicated within the same RF channel. For the 
MSI-8000 as network coordinator, MSI recommends a number for the  Dyna-
Link 2  from 0-3 if multiple units will be connected to the  MSI-8000. If a single 
Dyna-Link 2  is all that’s needed than any number up to 254 is acceptable. 
2. RF Channel – establishes the base netw ork, all interco
 nnected devices must 
match. This number must be in the range of 12-23. 
3. Network ID – this is a 64-bit number that all interconnected devices must match.  The  Dyna-Link 2  limi

ts this number to a max of 5 digits for a range of 0 - 99999. 
Do not use a small number here to help avoid other 802.15.4 networks that 
default to a network ID of 0.
4. RF Strength – Transmission strength can be set from 0 to 4, default is 1. The  settin gs 

effect the transmission range with zero is lowest power level and four is 
the highest. Power 4 will use the battery  life quicker, so use the lowest number 
possible for reliable transmission. If max imum range is needed set the strength 
to four.

NoteFor all devices that interconnect, the RF channel and network ID must 
match. The ScaleCore ID must be 
unique. The  Dyna-Link 2 or other 
MSI RF equipment that is a weight data source should be set to a 
ScaleCore ID of 0, then if other slave devices are added, they can be 
added in sequence.

1) With the power on, open the
COMM setup menu by
pressing the  F1 and  F2 keys
simultaneously.
The COMM setup menu
choice is Print.
2) Press F2 to scroll to the RF
setup menus.
3) Press F1 to enter the RF
setup menu.
4) The display reads  OnOff
by pressing F1. If it is off,
use the  F2 key to change it
to on. Then push  F1.
Off is only used when the 8000 is
hardwired to a Dyna-Link.
5) Press F1. Next the Scid
(ScaleCore ID) screen is
shown
6) Press F1. The current SCID
number is shown.
If the offered SCID value is correct,
push  F1 and jump to step 10.
In this example we’ll enter 3 as an SCID
number. Any value from 1-254 is
acceptable. However, MSI
recommends a value from 20 – 30.
7) To input the SCID value, press F2 to  start the number
entry process.
8) Use F2 to change the
number, and  F1 to enter
the number. Add the next
digit by pushing  F2 and
scrolling as required.
Repeat this sequence
until the entire SCID
number is entered.
9) Once the entire SCID value is entered, press  F1
10) The next RF setup
parameter is “ChnL”
(Channel). Press  F1 to start
the number entry process.
11)  The current RF channel number is displayed.
If the offered RF Channel value is
correct, push  F1 and jump to step 14.

							12) PressF2 and using the
previous process, enter
the RF channel number.
Recommended RF Channel numbers
range from 12 to 23. In  this example
we’ll use 21 as the RF Channel.
13) When the desired RF channel number is
shown and fixed, press
F1.
14) The next RF setup menu item is the nEtid
(Network ID). Press  F1
to see the current net ID
number.
If the offered network ID value is
correct, push  F1 and jump to step 17.
15) Using the numeric entry
process as before, input
a network ID number.
Press F2 to start a new
number.
Allowed network ID numbers range
from 0 to 99999. MSI rec ommends
a random number of at least four digits to ensure that the 8000
system won’t conflict with anyother 802.11.4 networks (Zigbee).
16) When the final number is
shown and fixed, press
F1 to store the network
ID.
17) The RF setup menu goes to the first menu,  OnOff.
Press the  ZERO key to
exit out of the RF setup
menus.
18) Press ZERO again to exit
the COMM setup menu
and store the new RF
network numbers.
