Using the Johnson Power Supply

1. Verify that the InterOP8500 is addressed

correctly.

2. Turn the Johnson Controls panel power

switch off.

3. Turn the InterOP8500 power switch off

(see Figure 1 on page 2).

4. Use the Power Adaptor Cable shown in

Figure 6 to connect power from the

Johnson power supply to the InterOP8500.

There is only one way for the connectors

on the cable to properly connect to the

indicated J terminals - do not force the

connectors on the wrong terminal.

5. Connect a grounding wire from the

chassis of the panel to the earth ground

terminal of the InterOp8500. See Figure 5

on page 6 for wiring.

6. Turn the InterOP8500 power switch on.

7. Turn the panel power switch on.

8. Make sure that the Communications

Power, Logic Power +5V, and Power +12V

LEDs are lit (located at the top edge of the

InterOp8500 board). See "LEDs" on

page 18.

Network Communications

The InterOP8500 module supports several

communications options through its CMnet

port.

On a SuperVision system, the InterOP8500

module can connect to a BACnet-over-

ARCNET network segment at 156 kbps, or to

a legacy CMnet at 9600 bps or 38.4 kbps.

When communicating at 156 kbps, the

network segment uses a unique

implementation of the industry standard

BACnet-over-ARCNET protocol called

ARC156. For a summary of the differences

between ARCNET and ARC156, please refer to

ARC156 CMnet Wiring Technical Instructions.

Use the appropriate wire for network

communications. When using an ARC156

network, use an A3ARC156 wire available

from:

Magnum Cable Corporation

Cleveland, OH 44110-0500

(800) 421-0820

Use a dedicated 22AWG to 18AWG twisted

pair wire for legacy CMnet (EIA-485) wiring.

For more information about CMnet wiring,

refer to the Technical Handbook or to ARC156

CMnet Wiring Technical Instructions.

1. Be sure the module's power is off before

wiring it to the network.

2. Check the network communication wiring

for shorts and grounds.

3. Connect the appropriate communications

wires to the module's screw terminals as

shown in Figure 7 on page 8. Be sure to

follow the same polarity as the rest of the

network.

4. Make sure the module is configured for

the correct baud rate. All modules on the
