Selecting the Jumpers
TIP: Use the “OptoScan” utility as an aid in setting jumpers.
There are two groups of jumpers located on each B1 or B2 brain board. The jumpers are labeled
Group A and Group B.
Group A Jumpers
These jumpers route wiring for repeat-mode or multidrop communications and also provide the
proper termination and biasing of the RS-422/485 network. All Optomux units on the same network
should be configured for either multidrop or repeat mode, but not both.
For multidrop operation, verify that the jumpers in group A are installed as follows:
X = INSTALLED
Install jumper A0 and A6 if the Optomux unit is the last unit in the serial data link.
For repeat mode settings, all Optomux bus should be jumpered as follows:
Group B Jumpers
This group of jumpers selects the Optomux address and baud rate. Each Optomux unit on the same
link must have a unique address (different from all others). All units on the same network should be
set for the same baud rate.
The following information is required to set the jumpers on a single Optomux unit.
