The ZB-2550-T/ZB-2551-T is a RS-485/RS-232 to ZigBee Network converter. It enables RS-232/RS-485 devices to be wirelessly and easily connected to a new or existing system.

The ZB-2550-T is net Host and the ZB-2551-T is net Slave.It also supports various data formats and Baud Rates that can be configured via a Windows-based GUI utility. The ZB-2550-T and the ZB-2551-T can implement an ad-hoc, star or mesh network topology.

In some existing systems that use a RS-485/RS-232 network, it is sometimes difficult to extend the new devices due to building structure issues, wiring problems or other reasons. The ZB-2550-T and the ZB-2551-T can be easily added to an existing system in order to extend your network.

The typical transmission range of the ZB-2550-T/ZB-2551-T converter is 100 m, and the ZB-2550P-T/ZB-2551P-T is 700 m

  • ISM 2.4 GHz operating frequency
  • Fully compliant 2.4G IEEE802.15.4 / ZigBee specifications.
  • Wireless transmission range up to 100 m(Line of sight).
  • GUI configuration software (Windows version).
  • DIN-Rail mount.

Transparent: (Original data will be broken down into many small data, each small data is 50 Byte)

Modbus: (Original data won't be broken down into small data)

Addressable: (Original data won't be broken down into small data)
