It is fully compatible with the Axcess Control System and can be used either as a stand-alone device or with other AMX bus devices. The AXB-EM232 runs complete Axcess programs, and controls other AXlink components and two devices using RS-232 as a control protocol. It can also control devices using RS-422 and RS-485 protocols.

AXB-EM232 Product Specifications Power 12 VDC, 160 mA · Data bits: 7 or 8 · Stop bits: 1 or 2 · Parity: None, Odd, Even, Mark, or Space Memory Front Panel Components: AXlink status LED Green LED lights to indicate AXlink communication as status as follows: · One blink per second : Power is active and AXlink communication is functioning. · Two blinks per second: Devices specified in the master program do not match the specified devices found. · Three blinks per second: Indicates an AXlink communication error. · Full-on indicates the following conditions: There is no AXlink control or activity, but power is on. The Axcess program is not loaded. RS-232 Program connector RS-232 Program DIP switch TX1 and RX1 LEDs This DB-9 RS-232 connector is used for AMX programming tools, such as Axcess and IRLIB. The 8-position DIP switch configures the communication parameters for the Program port. The red LEDs indicate that the AXB-EM232 is receiving (RX) or transmitting (TX) RS-232, RS-422, or RS-485 data. RX1 and TX1 correspond to Port 1 on the rear panel (See Rear Panel Components for a description of Port 1). The two 8-position DIP switches configure the communication parameters for the Ports 1 and 2 (See Rear Panel Components for a description of Ports 1 and 2). The red LEDs indicate that the AXB-EM232 is receiving (RX) or transmitting (TX) RS-232 data. RX2 and TX2 correspond to Port 2 (See Rear Panel Components for a description of Port 2). 64 KB battery protected memory, expandable to 256 KB Asynchronous data communication · Baud rates: 300, 600, 1200, 2400, 4800, 9600, 19200, or 38400 RS-232/422 1 and 2 DIP Switches TX2 and RX2 LEDs Rear Panel Components: Ports 1 and 2 AXlink connector Power supply connector Enclosure Dimensions (HWD) Weight Mounting options Optional Accessories: Power Supply Mounting Hardware · PSN2.8 (FG423-05) · PSN6.5 Domestic (FG423-41), International (FG423-43) AC-RK Accessory Rack Kit (FG515) There are two serial connectors: Port 2 is a 6-wire RS-232 captive-wire connector; Port 1 is an 8-wire RS-232/422 captive wire connector.

Follow these steps if your device requires this termination. 1. Discharge the static electricity from your body. 2. Unplug the two-pin power connector. 3. Remove the two screws on the front panel. 4. Remove the front panel, and slide the circuit board out of the enclosure. 5. Remove the jumper on pin trio E1 from pins 2-3 and place it on pins 1-2 (FIG. 2). 100 E1 12 3 12 3 12 3 HI Z FIG. 2 Communication jumpers 6. Replace the board in the enclosure. Then, replace the front panel, refasten the two screws, and plug in the two-wire power connector. Setting DIP switches Configure the device and programming communication ports' baud rate, data bits, stop bits, and parity. Use the eight-position DIP switches on the front panel to set the communications parameters. ! RS-232 PROGRAM DIP switch - Use the eight-position RS-232 Program DIP switch to set the communications parameters for the PROGRAM port. RS-232/422 DIP switches - Use the two eight-position RS232/422 DIP switches to set communications parameters for controlling the RS-232, RS-422, or RS-485 devices. ! ! ·Set Switch 1 to configure the parameters for Port 1 (RS-232/422/485). Set Switch 2 to configure the parameters for Port 2 (RS-232 only). ! AXB-EM232 Enhanced Master RS-232 Controller 3 Product Information Refer to the following table when setting the DIP switches.
