3.4.4 Connecting a Management Console Terminal to Multilink ML1200 (Serial-RJ-45
The serial console port on the Multilink ML1200 is different from other Multilink family
switches. The Serial RJ-45 port, as shown in the picture, requires an 8-pin RJ-45 male
connector to have the proper communication. (Note - the serial RJ-45 console port on the
Multilink ML1200 is compatible with Cisco-type RJ-45 console port cables).
The Serial port pin-out for the RJ-45 console port used on Multilink ML1200 is shown below.
The console RJ-45-Serial cable may be ordered from the Factory, using the model number
and description here:
CONSOLE-CBLQD- Console attachment cable serial null-modem cable with one side RJ-45
for the ML1200 and a male DB-9 Female connector on the other end.
CONSOLE-CBLQU- Console attachment cable serial null-modem cable Combo with one

For Power Substations: In support of the IEEE 1613 Class 2 standard, GE Multilin advises
that, for substation applications, the serial RJ-45console ports are intended for temporary
connectivity to other equipment such as PCs. Since the console port connection is
temporary, it is excluded from IEEE 1613 packet-loss testing per the 1613 standard-
defined test procedure.
