FOCUS System Manual

Repeat Steps 5–7 for channel B. Be sure to

connect to channel B on both (232) module

interfaces.

To test the 232 modules with modems, complete

the following steps:

1. Install the 232 module and interface.

2. Start the FCS.

3. Bring the FOCUS chassis “on line”.

4. Unlock the FOCUS chassis.

5. Connect the two modems to the modules.

Connect one modem to channel A of the

module interface on one chassis and the other

modem to channel A of the module interface

on the other chassis.

6. Test the modems.

Dial from the “local” modem to see if you can

communicate with the “distant” one. Then

reverse direction, dialing from the “distant”

chassis to the “local” one.

Repeat Steps 5–6 for channel B.

The schematic for the Low Speed Data (232)

Module and interface is available upon request.

The location of each of the components on the

Low Speed Data (232) Module and interface are

shown at the end of this chapter.

Steps 1–4 are the same as for the “data flow”

test. If you have just done them for that test,

skip them here and begin with Step 5.
