Connecting the configuration terminal
Connect a PC or terminal to Port 1 on the rear of PortServer II to use during the con-
figuration procedure described in
Chapter 4, Basic Configuration
. You can subse-
quently use this terminal for system management or other purposes. If you use a PC,
you will require a terminal emulator program.
1. Obtain a suitable cable to connect your terminal to the serial port on PortServer II.
The RJ-45 to DB-25 cable leg connector supplied with PortServer II was intended
for this purpose. If you prefer, you can also construct or obtain your own cable.
If you construct or obtain your own cable, you only need to connect the TxD
(Transmitted Data), Received Data (RxD), and Signal Ground (SG) cables, as
shown below.
Figure 13 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).
2. Fit the DB-25 connector to the terminal. If your terminal does not have a DB-25
connector, you will also have to obtain an adapter.
3. Fit the RJ-11 or RJ-45 plug to PortServer II. If you use an RJ-11 plug, ensure that
you center it on the jack.
