➀
RS-232 Ports:
Standard DB9 connectors configured as DTE ports for
connection to switched devices. The RS-232 ports are similar to standard serial
ports on a PC. When connecting a modem, use a standard serial cable. When
connecting a PC or other DTE device, use a null-modem cable.
Ports 1 and 2 are used for communication during set-up and configuration.
When the Port Manager is initialized to defaults, Ports 1 and 2 are the only
ports with access to All (Administrator) commands. Access to Administrator
commands
can’t
be disabled at Ports 1 and 2, so be careful what you connect to
them.
➁
Setup Switches:
A bank of eight DIP switches that you’ll use to set the default
baud rate, handshake, message type, and duplex mode. These Setup Switches
are on the rear panel of 8-port units, but they’re on the bottom of 16-port units.
