ATC-3200 ZigBee RS232/RS485/RS422 radio modem – single unit

ATC-3200 ZigBee Serial Radio Modem – Single Unit

This item includes an ATC-3200 radio modem and related accessories. It is intended for expanding existing wireless serial networks or creating new connections in conjunction with other compatible modules. At least two ATC-3200 modules are required to create a point-to-point link ; the second unit is not included. The single module requires at least one other ATC-3200 unit in the network and can be used as an additional node to extend an existing network and create point-to-multipoint links.

ZigBee wireless serial communication

The ATC-3200 connects RS232, RS422, and RS485 devices via a 2.4 GHz ZigBee radio network. It is suitable for replacing a wired serial link and for creating point-to-multipoint networks with additional modules. The devices operate in a master/slave configuration and transfer serial data transparently after configuration.

The supplied Windows software allows you to set the PAN ID, radio channel, and serial parameters. The configurable encryption key protects radio communication; modules on the same network must share the parameters required for connection.

Technical features

• Power supply: 9–24 V DC; serial power optional.
• Declared conformity: CE and RoHS.

The datasheet indicates a radio range of up to 500 m under specified RF conditions (12 dBm and sensitivity −102 dBm). Actual range depends on obstacles, interference, antenna placement, and installation environment.

Initial setup

1. Connect the first module to the PC via the RS232 cable and power it on. Activate configuration mode with the dedicated button until the LEDs flash.
2. Open the program, select the COM port, and set the PAN ID, channel, speed, serial parameters, and encryption key on the master. Write the parameters with the "Write To Master" command.
3. Connect the slave module, activate configuration mode, and transfer the same network parameters with "Write To Slave." Repeat for any additional nodes.
4. Connect the modules to serial devices and verify data exchange. Terminal software for testing is also provided.
