Performing Communications

The PDT 7500 terminal communicates with a host either through an RS -232
communications cable, or placed in a CRD 7500 or VCD 7500 cradle. PDT 7540 terminals
communicate with a host computer or other wireless units over the Spectrum24 wireless LAN
network.

Communicating via RS-232 Cable

To perform direct communications using an RS-232 cable, connect the terminal to the host
via the communications port:
1. Suspend (temporarily power the terminal off) the terminal by pressing the PWR key.
2. Connect the communication cable's connector to the adapter cable's connector.
3. Plug the adapter's subminiature connector in the communications port on the
bottom of the terminal.
4. Plug the other connector on the communication cable to the host's COMM port.
5. Start the communications program.

Communicating via Cradle

The cradle enables communications between the PDT 7500 and a computer, printer, modem,
or other peripheral device.
CRD 7500 Four-Slot Cradle and VCD 7500 Vehicle Cradle
To begin communication:
1. Make sure all power and serial connections are secure.
2. Insert the terminal in the cradle.
3. As determined by your specific application, press the appropriate key(s) on the
terminal to initiate communication.
The cradle's Communications LED blinks yellow when communication begins.
Removing the terminal while the cradle's Communications LED is on or
flashing disrupts communication between the host and the terminal.
