Setup guide

Setting up the Hardware

Plug RS-232

null modem

cable into

COM2

• Switch bank SW1: all switches in the ON position, unless this I/O rack is part of a

redundant pair. (A redundant pair would require two I/O Expansion Racks, hooked

through a ControlWave Redundant I/O Switcher (CWREDIO) to the host

ControlWave unit(s).)

If this I/O rack is part of a redundant pair, set switch SW1-6 and SW1-7 as shown in

the table, below:

For these switches: If this I/O Expansion Rack is part of a

redundant pair…

SW1-6 This must be set OFF.

SW1-7 This switch must be set either ON or OFF

based on whether this is the "A" I/O rack or the

"B" I/O rack of this redundant pair.

• SW1-7 must be ON if this is the "A" rack

• SW1-7 must be OFF if this is the "B" rack

• Switch bank SW3: all switches in the OFF position, except SW3-4, which you will

want to set to the ON position to enable the backup battery when the I/O Expansion

Rack is ready to be put into service. If the rack is NOT going to be put into service for

an extended period of time, leave this OFF to avoid draining the battery.

4. For the configuration activities, described in this manual, we will use Serial Communication

Port 2 (COM2) on the rack, which is configured by default for 9600 baud. (For more

information on communication ports see Section 2.3.3.2 of CI-ControlWaveEXP).

• Plug one end of an RS-232 null modem cable

into one

of your PC communication ports.

• Plug the other end of the RS-232 null modem cable

into Serial Communication Port 2 (COM2) of the I/O

Expansion Rack

5. Remove I/O Modules from their cartons and install them into the Chassis. I/O Modules

reside in slots 3 through 4, 3 through 6 or 3 through 10 for units supporting 2, 4 or 8 I/O

Modules respectively. Install I/O wiring to each I/O Module (see Section 2.3.4 of CI-

ControlWaveEXP).

For a wiring diagram of an RS-232 null modem cable, see Figure 2-8 in the CI-ControlWave manual.
