the rear panel of the RS-232 key.
2. Connect the appropriate COM port adapter (DB-9) to the serial port on the
back of the computer. Plug the 8-conductor cable from the RS-232 key into
the COM port adapter.
3. Connect the provided AC adapter into the rear panel input on the RS- 232
key. Plug the adapter into a 120VAC outlet. On the front panel of the RS-232
