Product Information Product Information The AXB-232++ RS-232/422/485 Interface is an AXlink bus controller that provides remote control for devices that require a variety of control protocols. The AXB-232++ extends RS-232, RS-422, or RS-485 control to remote sources over the 4-wire AXlink data/power bus. Onboard processing and memory allows the controller to take on complex tasks by itself, reducing the processing burden for the Axcess control system. For example, the control system can use

Product Information Specifications The following table lists the specifications for the AXB-232++. Specifications Power 12 VDC @ 160 mA Processor On board 32-bit processor and 384K (of non-volatile memory) run Axcess programs independent of the control system. This relieves the AXlink bus and controller for the processing time for controlling those devices. (Requires Axcess Version 3.0 or higher.) Asynchronous data • Baud rates - 300, 600, 1200. 2400, 4800, 9600, 19200 and 38400. standards 5

Installation and Wiring Setting jumper JP5 to set the RS-422 port for RS-485 use 1. Disconnect the RS-232/422/485 connectors. 2. Unscrew the two screws on the rear panel, and remove the panel. 3. Slide the circuit board out of the enclosure. 4. Locate the JP5 jumper (see FIG. 3 on page 3). 5. Set jumper JP5 to the ON position (the default setting is OFF). 6. Slide the circuit board back into the enclosure. 7. Replace the panel, and refasten the screws. 8. Reconnect the RS-232/422/485 connectors.

Installation and Wiring Setting the RS-232/422 DIP switch Set the stop bits, data bits, parity, and baud rate on the RS-232/422 DIP switch, located on the front panel (see FIG. 1 on page 1). The AXB-232++ supports the following asynchronous data standards: Stop bits 1 and 2 Data bits 7, 8, and 9 Parity None, Odd, Even, Mark, and Space Baud rates 300, 600, 1,200, 2,400, 4,800, 9,600, 19,200 and 38,400. 57,600 is achieved by setting the DIP switch to 300 baud, and using the ’BAUD

Installation and Wiring 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. 2. Tin 2/3 of the exposed wire. 3. Insert each wire into the appropriate captive-wire connector up to the insulation. 4. Tighten the captive screws to secure the fit in the connector. If the device is using a separate power supply, do not connect the power wiring from the AXB-232++ to that device. Wirin

Installation and Wiring 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 two screws on the front panel of the AXB-232++. 3. Remove the front panel and space bracket behind the panel. 4. Place the unit in the appropriate opening in the AC-RK. 5. Place the front panel of the AXB-232++ on the front of the rack, over the unit. 6. Fasten the

Programming Programming Send_Commands The AXB-232++ supports the same command set as the AXC-232. The following table lists the AXB-232++ Send_Commands. AXB-232++ Send_Commands B9MOFF Syntax: Sets data bit mode to normal 'B9MOFF' with DIP switch settings Example: (default). SEND_COMMAND AXB232,'B9MOFF' Sets the data bit mode to normal. B9MON Syntax: Enables a special mode to 'B9MON' override DIP switch settings. The mode, nine data bits with one stop bit, overrides the data, stop, and pari

Programming AXB-232++ Send_Commands (Cont.) CHARD Syntax: Sets delay between all 'CHARD-' transmitted characters to the Variable: increment specified. time = 100 microsecond increments 0 - 255. Example: SEND_COMMAND AXB232,'CHARD-10' Sets 1mS delay between all transmitted characters. CTSPSH Syntax: Enables PUSHes and 'CTSPSH' RELEASEs. Example: SEND_COMMAND AXB232,'CTSPSH' Enables PUSHes, RELEASEs, and status on channel 255 ([0,255] within the AXB-232++) for CTS hardware handshake input.
