AXB-232++ AXB-232++ Overview The AXB-232++ RS-232/422/485 Interface (FG5761-10) 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. - Page 6 AXB-232++ Specif ications (Cont.) Rear Panel Hardware handshaking An RTS/CTS data connector that can be wired for hardware handshaking if called for by the controlled device connector (4-pin male). RS422/232 connector A captive-wire connector wired for RS-422/232 data control (8-pin male). AxLink connector Receives power and data via the AxLink bus and AxLink system controller (4-pin male).

Installation and Wiring Rack-Mounting the AXB-232++ (Optional) To rack-mount the AXB-232++ into the optional AC-RK Accessory Rack Kit: Remove any connected power, and AxLink and RS-232 connectors from the rear panel. Remove the 2 screws on the front panel of the AXB-232++, and remove the front panel as well as the space bracket behind the panel. -
Page 12: Programming
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 Sets data bit mode to normal with DIP switch settings (default). Syntax: 'B9MOFF' Example: SEND_COMMAND AXB232,'B9MOFF' Sets the data bit mode to normal. B9MON Enables a special mode to override DIP switch settings. -

Programming AXB-232++ Send_Commands (Cont.) CTSPSHF Disables the 'CTSPSH' command. Syntax: 'CTSPSHF' Example: SEND_COMMAND AXB232,'CTSPSHF' EOFF Disables the 'EON ' command (default). Syntax: 'EOFF' Example: SEND_COMMAND AXB232,'EOFF' Forces the AXB-232++ to ignore transmitted characters on its receiver. When using RS-485, the TX and RX are tied together. Syntax: 'EON' Example:... -
Page 14: Axcess Program Characteristics
Programming Axcess Program Characteristics The AXB-232++ is capable of running Axcess programs. It handles string processing, relieving AxLink and the Master of the processing times. Send_String Escape Sequences The AXB-232++ does not regard certain three-character combinations within a Send_String program as literal characters, but as commands. - Page 15 Programming AXB-232++ Program Statements The Axcess program of the AXB-232++ communicates with the master as Device 0. Its device communicates with the RS232/422 Input/Output (I/O) of the AXB-232++ as Device 1. The following table lists AXB-232++ statements. AXB-232++ Program Statements Statement Function Places strings that come from the Master into buffer.
- Page 16 Programming AXB-232++ Program Statements (Cont.) Turns on a channel or variable for a certain amount of time. Once the time elapses, the PULSE channel or variable is turned off. The Pulse time remains the same value until it is changed within the program.
