Digi PortServer/8 User Manual page 14

Connect other terminals and peripherals to the PortServer
At this point you may wish to connect other devices (terminals, modems or printers) to the
PortServer. If you'd prefer to "play with it" a bit and add other peripherals later, skip this part
and go to the next section, Log in and Configure the PortServer on page 9.
Terminals
Attach terminals to the other ports as previously described, plugging the RJ-45 or RJ-11
connectors (from the terminals) into the appropriate sockets in the back of the PortServer. All of
the ports are equal, and you can configure any port for any device. Make sure the power is off on
the PortServer and the terminals!
Some terminals require hardware handshaking; most that do use Data Terminal Ready (DTR) for
hardware handshaking. Here is a wiring diagram for this method:
