Modem Data-Only Stations

Figure 6–2 shows the equipment configuration for a modem data-only station.

To set up a modem data-only station, follow the steps below:

! If using an external modem, use an EIA-232-D cable to connect the modem to the serial port on the data terminal. If using an internal modem, it should already be connected.

For a data terminal that has both COM1 and COM2 ports, make sure you use the one designated for data transmission. See the customer’s system manager if you are not sure.

! Make sure that the modem has settings for speed and parity that are compatible with those of the data terminal.

If you are not sure, see the customer’s system manager or the documentation packaged with the modem, data communications software, and data terminal.

! Connect the modem to the control unit.

a.Plug one end of a D4BU cord into the appropriate modem jack; see the modem’s documentation if you are not sure.

b.Plug the other end into the appropriate basic extension jack on the

012 or 008 OPT module. See Form 2a, System Numbering: Extension Jacks for the appropriate module and extension jack.

! Connect all power cords to an AC outlet that is not controlled by a wall switch.
