Terminal Adapter Data-Only
Stations
Figure 6–5 shows an equipment configuration for a terminal adapter data-only
station.
To set up a terminal adapter data-only station, follow the steps below:
1 Use an EIA-232-D cable to connect the SERIAL port on the data terminal
to the terminal adapter.
For any data terminal that has both COM1 and COM2 connectors, make sure
you use the one designated for data transmission. See the customer's system
manager if you are not sure.
2 Make sure that the terminal adapter option settings for parity and speed
are compatible with the data terminal. (Speed is synchronized
automatically if the factory setting has not been changed.)
If you are not sure about the speed and parity of the data terminal, see the
customer's system manager or the documentation packaged with the terminal
adapter and the data terminal.
3 Plug the other end of the EIA-232-D cable into PORT 1 on the terminal
adapter.
4 Plug the WP90110-L7 power supply cord into the POWER receptacle on
the terminal adapter.
5 Use a 440A4 terminating resistor adapter to connect the terminal adapter
to the control unit.
