Connecting the EIA-232-D Cable 3
Connect the EIA-232-D cable between the 8400B Plus and the PC as follows:
1. Insert the male connector of the EIA-232-D cable into the connector labeled
“Port 1” on the rear panel of the 8400B Plus. Tighten both connector retaining
screws.
2. If the communications port connector on the PC has nine pins, do the following:
— Plug the remaining end of the cable into the 25-pin portion of the M25/F9
Adapter.
— Plug the 9-pin portion of the M25/F9 Adapter into the EIA Connector
Interface on the communications port. Tighten both connector retaining
screws.
If the communications port connector on the PC has 25 pins, you do not need
the M25/F9 Adapter—just plug the connector cable into your PC’s 25-pin port.
3. Tighten all retaining screws.
