Bluetooth to RS232/RS422/RS485 converter
Based on Bluetooth technology TRP-C51 allows you to wirelessly connect your RS232/422/485 devices to systems within the range up to 100M. The TRP-C51 features wide range power input, auto RS232/422/485 signal switching and internal surge protection on RS422/485 lines. It also supports all common data format and baud rate which can be configured by the bundled TRP-BT utility from Windows system. TRP-C51 can operate in “Direct link mode” and “Paired mode” When in paired mode, the user just need to power two devices, and they will automatically connect without software and hardware changes on your systems that will replace your serial wire with a completed transparent wireless connection. It can be used for wide range of applications for wireless operation and monitoring process.
