AXB-232++ RS-232/422/485 Interface
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
simplified commands for generic video switcher or code control, a modular driver program in the
AXB-232++ can process control for specific makes and models.

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
standards
Buffers • 1KB input buffer
Front Panel
AXlink LEDs Green AXlink status indicator:
RX LED (Red) Blinks to indicate the AXB-232++ is receiving RS-232, RS-422, or RS-485 data.
TX LED (Red) Blinks to indicate the AXB-232++ is sending RS-232, RS-422, or RS-485 data.
DEVICE DIP Switch An eight-position DIP switch used to set the device number for the AXB-232++.

• Data bits - 7, 8, and 9
• Stop bits - 1 and 2
•Parity - None, Odd, Even, Mark and Space
• 1KB AXlink buffer
• Full-Off indicates no power is being received or the controller is not functioning
properly.
• One blink per second power is active and AXlink communication is functioning.
• Full-On indicates power is active and AXlink data communication is not
functional.
The RX LED blinks even if the data being received is incorrect.
