TRP-C51
Bluetooth to RS232/422/485
Converter
Wiress Serial Device
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, If
using the outdoor direction antenna can up to
1KM (option) , 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.
