10BASE-T (MODULAR) CONNECTION

If your network uses 10BASE-T RJ-45 connectors, connect an RJ-45 cable between the

RJ-45 port and the network hub. The modular port is defined as DTE (i.e., Pin 1 is

TD+, Pin 2 is TD-, Pin 3 is RD+, and Pin 6 is RD-). Most RJ-45 network hubs will

require a straight cable type. The LINK (link integrity) LED on the back panel and at

the connected port on the hub will illuminate if there is a good connection between the

V72/V72TP and the hub.

V74/V75/V87 CABLING

Ports on the V74 & V75 modules use the following pins and signals for

communication:
