ISACC Instruction Manual
ISACC is capable of communicating locally at the following speeds:
150 bps 2400 bps
300 bps 4800 bps
1200 bps 9600 bps
There are 9 pins at location P10. (P10 is located under the acrylic safety panel next to the
digital outputs terminal block.) Three shunts are provided to configure the communication
speed for the RS232 port. The speed is determined by the different positions of the shunts.
All three shunts must be used for ISACC to communicate properly. To configure the shunts,
you must first remove the acrylic panel. Using needlenose pliers, move the shunts to the
appropriate positions. Replace the acrylic panel when finished. See diagrams below.
