Product Information

Product Information

The AXB-232++RS-232/422/485Interface is an AXlink bus controller that provides remote control for devices that require a variety of control protocols. TheAXB-232++extendsRS-232,RS-422,orRS-485control to remote sources over the4-wireAXlink 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-bitprocessor and 384K (ofnon-volatilememory) 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, 19200and 38400.

standards

56400 is supported via the BAUDMED Send Command (see the

 

 

Send_Commands section on page 9 for details).

 

115200 is supported via the BAUDHIGH Send Command (see the

 

Send_Commands section on page 9 for details).

 

• Data bits - 7, 8, and 9

 

• Stop bits - 1 and 2

 

• Parity - None,Odd,Even,Mark andSpace

 

 

Buffers

• 1KB input buffer

 

• 1KB AXlink buffer

 

 

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 receivingRS-232,RS-422,orRS-485data.

 

The RX LED blinks even if the data being received is incorrect.

 

 

TX LED (Red)

Blinks to indicate the AXB-232++is sendingRS-232,RS-422,orRS-485data.

 

 

DEVICE DIP Switch

An eight-positionDIP switch used to set the device number for theAXB-232++.

 

Refer to Setting the DEVICE DIP switch, onpage 4, and Setting jumper JP5 to set

 

the RS-422 port for RS-485 use section on page 4 for more information.

 

 

RS232/422 DIP Switch

An eight-positionDIP switch used to set the communication parameters for the

 

RS-232/422device. Refer toSetting the RS-232/422 DIP switch, onpage 5, for

 

more information.

 

 

Rear Panel

 

 

 

Hardware handshaking

An RTS/CTS data connector that can be wired for hardware handshaking if called

connector

for by the controlled device (4-pinmale).

 

 

RS422/232 connector

A captive-wireconnector wired forRS-422/232data control(8-pinmale).

 

 

AXlink connector

Receives power and data via the AXlink bus and AXlink system controller

 

(4-pinmale).

 

 

Internal Jumpers

Sets differential input termination and enables RS-485output.

 

 

Supports

XON/XOFF software and hardware handshaking
