5.6 COMMUNICATION
This was discussed briefly in the section under “REGISTER SELECT” and will be fully explained here. When you
choose your register type under the REGISTER SELECT menu, this automatically formats the VSI-Pro to the appro-
priate settings needed to communicate with your register. There may be times when you will need to amend these
settings for a specific register.
To access the Communication menu, press the “Up” or “Down” button to move the cursor to “COMMUNICATION”
and press “Set”. The following menu will appear:

your selection. When your selection appears, press “Set” again. The cursor will stop flashing and you can proceed to
the next menu item for programming. RS-232 and RS-485 are defined by IEEE standards, however, the Passive Tap
is a high impedance (100K) input with full diode protection. Refer to Table 1 and 1A for respective pin-outs of RS-232
or RS-485.
