Editor Port Jumpers
Editor Port Jumpers
Jumper settings on the Control Processor module must be set as follows for proper
operation of the EDITOR port:
Model 3000
For the Model 3000, the EDITOR port jumpers are located on the Control
Processor module (068906) between the M/E 2 Processor mezzanine board
(068916) and the Serial Communications mezzanine board (068918). See Figure 1-
1. Jumper J71 sets the communication standard (RS-232 or RS-422); Jumper J70 sets
the EDITOR port termination (IN or OUT).
Communication Standard
For RS-422 , set the two jumpers of J71 to the DIFF position (RS-422) as shown
in Figure 1-1. This connects pins 1 and 3 together and pins 2 and 4 together.
For RS-232 , set the two jumpers of J71 to the RS232 position. This connects pins
3 and 5 together and pins 4 and 6 together.
Termination
Set the two jumpers of J70 to either the IN (terminated) position or the OUT (not
terminated) position, depending on the requirements of your system.
If J71 is set for RS-232, Jumper J70 has no effect.
