VDC Slot Assignments - Backplane VDC Port
Combinations of switches 2, 3, and 4 within SW8 are used to assign Virtual Data Cable Slots for the backplane VDC
port. The following table lists the possible settings for the 14 VDC Slots available in a Pro64 network.
Note that RS‑232/422 communication always requires a pair of Virtual Data Cable Slots and that this pair must
always be an odd‑even combination of VDCs. The down position is
off
and the up position is
on
for each DIP
switch.
