Connecting to terminals and PCs
You can connect a terminal to any available serial port on PortServer II.
1. Obtain a suitable cable to connect the terminal to the serial port on PortServer II.
The wires that must be available depend on whether the terminal requires hard-
ware handshaking.
If the terminal does not require hardware handshaking, you can use a simple 3-
wire cable as shown below:
Figure 14 Simple 3 Wire cable
Note:
Any cable you construct or obtain must be shielded to comply with FCC certi-
fication requirements. The shield must be connected to Chassis Ground
(GND) at one end of the cable.
In addition to the configuration illustrated above, you can also use a 6-pin RJ-11
plug, or an 8 pin or 10 pin RJ-45 plug. (See Page 35).
If the terminal requires hardware handshaking, use the cable shown on the follow-
ing page. This configuration assumes the terminal uses Data Terminal Ready
(DTR) for handshaking; check your terminal or PC documentation for further
information.
