corresponding values.

Wiring Devices to the AXB-232++

Preparing Captive Wires

To connect the wiring into a captive-wire connector:

1. Strip 1/4 inch off the wire insulation for all four wires and tin 2/3 of the exposed wire.

2. Insert each wire into the appropriate captive-wire connector up to the insulation.

3. Tighten the captive screws to secure the fit in the connector.

Note: If the device is using a separate power supply, do not connect the power wiring from

the AXB-232++ to that device.

Wiring Guidelines

The interface requires a 12 VDC power to operate properly. The interface uses a PSN2.8

power supply. The Central Controller supplies power via the AxLink cable or external 12 VDC

power supply.

The maximum wiring distance between the Central Controller and interface is determined by

power consumption, supplied voltage, and the wire gauge used for the cable.

The table below lists wire sizes and maximum lengths allowable between the AXB-RS232++

and Central Controller.

The maximum wiring lengths for using AxLink power are based on a minimum of 13.5 volts

available at the Central Controller’s power supply.

Using AxLink

Connect the AxLink wiring to the connector on the AXB-232++ as shown in FIG. 3. i

Using AxLink and External Power Supply

Connect the AxLink and power wiring to the connector on the AXB-232++ as shown in

FIG. 4.

Using RS-232

When communicating via RS-232, connect the wiring as shown in FIG. 5.

Using Hardware Handshaking

When the controlled device requires hardware handshaking, connect the wiring as shown in

FIG. 6.

Using RS-422

When communicating via RS-422, connect the wiring as shown in FIG. 7.

Using RS-485

When communicating via RS-485, connect the wiring as shown in FIG. 8.

Rack-mounting the AXB-232++ (optional)

To rack-mount the AXB-232++ into the optional AC-RK Accessory Rack Kit:

1. Remove any connected power, and AxLink and RS-232 connectors from the rear

panel.

2. Remove the 2 screws on the front panel, and remove the front panel and the space

bracket behind the panel.

3. Place the unit in the appropriate opening in the AC-RK.

4. Place the front panel of the AXB-232++ on the front of the rack, over the unit.

5. Fasten the front panel to the rack and unit with the two screws you removed.

Replacing the Lithium Batteries

The AXB-232++’s lithium batteries have a life of approximately 5 years to protect its memory.

When DC power is on, the batteries are not used. When you install the AXB-232++, record

the date the batteries should be replaced.

Note: There is a danger of explosion if you replace the batteries incorrectly. Replace

batteries with the same or equivalent type recommended by the manufacturer. Dispose of

the used batteries according to the manufacturer’s instructions. Never recharge,

disassemble, or heat batteries above 212°F (100°C). Never solder directly to the batteries or

expose the contents of the batteries to water.

Before removing the lithium batteries, contact your dealer and verify that they have a current

copy of your program to avoid an inadvertent loss of data and prevent an unnecessary

service outage.

1. Discharge the static electricity from your body.

2. Unplug the 2-pin power connector and any other connectors.

3. Remove the 2 screws on the front panel, remove the front panel, and slide the circuit

board out of the enclosure.

4. Carefully slide each battery out of its socket, and insert the new battery.

5. Slide the circuit board back into place, replace the front panel and refasten the screws.

6. Reconnect any connectors that you removed.
