AXB-232++ - Instruction Manual
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. 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.
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.)

Front Panel
AxLink LEDs Green AxLink status indicator:
•
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.
RX LED (Red) Blinks to indicate the AXB-232++ is receiving RS-232, RS-422, or RS-485 data.
The RX LED blinks even if the data being received is incorrect.
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++. Refer to Setting the DEVICE
DIP switch, on page 8, and Setting Jumper JP5 To Set the RS-422 Port For RS-485 Use section on page 7 for
more information.
RS232/422 DIP Switch An eight-position DIP switch used to set the communication parameters for the RS-232/422 device. Refer to
Setting the RS-232/422 DIP switch , on page 8, for more information.
