1. Introduction.
Based on Bluetooth technology TRP-C51 allows you to wirelessly connect your RS-232/422/485
devices to systems within the range up to 100M, TRP-C51 features wide range power input, auto
RS-232/422/485 signal switching and internal surge protection on RS-422/485 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.
