Connecting a Terminal to a Comm (Terminal) Port
The DL3100 has two 9-pin comm port sockets on its rear panel, labeled
TERMINAL and NETWORK MANAGEMENT. These are provided for
connection to the ASCII terminal or SNMP workstation.
To connect a terminal to the TERMINAL port socket on the DL3100 rear
panel:
▼ Using the DE-9 RS-232 straight-through ribbon cable, connect
the DE-9 plug into the DL3100 DE-9 socket and the other end
into the terminalÕs connector. Figure 4-1 shows the TERMINAL
and NETWORK MANAGEMENT ports on the rear panel.
Figure 4-1 Ports on the Rear Panel
NOTE: To enable daisy-chaining—Pin 8 (CTS) on the comm port side
of the connector is connected to Pin 8 on the other connector. If your
cable is not from Digital Link, be sure that pin 8 is disconnected at the
terminal end of the connector.
Regarding Distance: If the comm port baud rate is 9600, place the
terminal within 50 feet of the port. You may increase the distance if you
reduce the baud rate.

 ONLY WITH SAME TYPE AND RATING OF FUSE.
