Connecting Data Equipment

1. Connect the data terminal to the data module:

a . Connect an EIA-232-D cable to the SERIAL connector on the data terminal.

NOTE:

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 administrator if you are not sure.

b . Make sure that the data module option settings for parity and speed are compatible with those settings of the data terminal, (Speed is synchronized automatically when the factory default settings remain unchanged.)

If you are not sure about the data terminal option settings, see the customer’s system administrator or the documentation packaged with the data module and data terminal.

c . Connect the other end to PORT 1 on the data module,

2.Plug the WP90110-L7 power supply cord into the POWER connector on the data module.

3.Connect the data module to the control unit using a 440A4 terminating resistor adapter:

a.Connect the 440A4 terminating resistor adapter to the PHONE jack on the data module, using a D8W cord.

b.Connect the other end of the adapter to the appropriate MLX station jack, using another D8W cord. See Form 2b, System Numbering—Digital Adjuncts for the appropriate module and station jack.

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