Section 2 — Installation
Editor Port Jumper Settings—
There are two sets of EDITOR port jumpers which
are located on the Control Processor II module (064806) as shown in Figure 2-43 .
Jumper J15 sets the communication standard (RS-232 or RS-422); Jumpers J16, J17,
and J18 set the EDITOR port termination (terminated or not terminated).
NOTE:
If you are using either the Sabre Edit or Super Edit GVP editors, the factory
default settings are correct and you may skip this section.
Communication Standard
— For RS-422, set the two jumpers of J15 to the upper
(RS422) position as shown in Figure 2-43 . This connects pins 1 and 3 together and
pins 2 and 4 together.
For RS-232 set the two jumpers of J15 to the lower (RS232) position. This connects
pins 3 and 5 together and pins 4 and 6 together.
Termination
— Set jumpers J16, J17, and J18 to either the upper (terminated) or
lower (not terminated) position, depending upon the requirements of your system.
All three of these jumpers should be set to the same position (all up or all down).
There is only one jumper for each of these jumper blocks.
If J15 is set for RS-232, Jumpers J16 through J18 have no effect.
