VSBC-6862 Rev 1.43

Termination network resistors

When the RS-422/RS-485/V.35 is chosen, the VSBC-6862 is provided with removable network

resistors.

Each resistor network is located as:

RZ34, RZ35: port SCC 1

RZ36, RZ37: port SCC 2

RZ38, RZ39: port SCC 3

RZ40, RZ41: port SCC 4

Note that the pins 1 of these removable networks are in opposed side than the already soldered

resistor network.
