AXB-232++ RS-232/422/485 Interface

Overview

The AXB-232++ (FG5761-10) can serve as a conventional RS-232/422 control port, it is also

able to run its own Axcess application program – an exclusive AMX product feature. Source

specific programming, such as video switchers, laserdisc players and video codecs, can be

handled by the AXB-232++ to deliver a modular solution for system programming.

Specifications

The following table lists the specifications for the AXB-232++.

Installation and Wiring

The AXB-232++ can be used as an independent RS-232/422/485-controlled interface by

setting the internal jumpers. Configure the communication parameters using the DIP

switches on the front panel.

Setting the Internal Jumpers

Setting Jumper JP4 To Terminate RS-422 Input With 100 ohms

Terminating a device involves installing a 100 ohm line terminator, this is typically used to

achieve better communication and signal integrity. You will want to terminate when the

communication is at a high data rate or over a long distance.

Termination can be harmful because it increases the current in the line, and more radiation

that could interfere with signals.

Jumper JP4 places 100 Ohms termination across RS422 receive data pins 5 & 6:

1. Disconnect the RS-232/422/485 connectors.

2. Unscrew the two screws on the rear panel to remove the panel, and slide the circuit

board out of the enclosure.

3. Locate the JP4 jumper and install the jumper in the 'ON' position (default = OFF).

4. Slide the circuit board back into the enclosure and replace the rear panel.

5. Reconnect the RS-232/422/485 connectors.

Setting Jumper JP5 To Set The RS-422 Port for RS-485 Use

1. Disconnect the RS-232/422/485 connectors.

2. Unscrew the two screws on the rear panel to remove the panel, and slide the circuit

board out of the enclosure.

3. Locate the JP5 jumper and set jumper JP5 to the ON position (default setting is OFF).

4. Slide the circuit board back into the enclosure and replace the rear panel.

5. Reconnect the RS-232/422/485 connectors.

Setting the DIP Switches

Note: Use the DIPSwitch 2.0 application available for free download from AMX to quickly

figure out DIP Switch settings for all types of DIP Switches.

Setting the DEVICE DIP switch

Set the device number on DEVICE DIP switch, located on the front of the AXB-232++. The

device can be 1 of the 255 devices in an Axcess control system. The device number must

match the device assignment in the Axcess program. Device numbers are assigned into the

following three segments:

• Cards 1 through 95

• Boxes 96 through 127

• Panels 128 through 255

Set the device number by setting the device DIP switches. The device number is the total of

all of the switches in the ON position, and take effect by cycling the power.

Setting the RS-232/422 DIP switch

Set the stop bits, data bits, parity, and baud rate on the RS-232/422 DIP switch, located on

the front panel. The AXB-232++ supports the following asynchronous data standards:

• Stop bits 1 and 2

• Data bits 7, 8, and 9

• Parity None, Odd, Even, Mark, and Space

• Baud rates 300, 600, 1,200, 2,400, 4,800, 9,600, 19,200 and 38,400.

57,600 is achieved by setting the DIP switch to 300 baud, and using the ’BAUDMED’

SEND_COMMAND (see the AXB-232++ Operation/Reference Guide for details).

115,200 is achieved by setting the DIP switch to 300 baud, and using the ’BAUDHIGH’

SEND_COMMAND (see the AXB-232++ Operation/Reference Guide for details).

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

• Baud rates - 300, 600, 1200. 2400, 4800, 9600, 19200 and

38400.

56400 is supported via the BAUDMED Send Command .

115200 is supported via the BAUDHIGH Send Command

(see the AXB-232++ Operation/Reference Guide for

details).

• Data bits - 7, 8, and 9

• Stop bits - 1 and 2

•Parity - None, Odd, Even, Mark and Space

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 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.
