RS485 Bluetooth adapt
BTS5504C2P
Bluetooth RS485adapt can use for various of house hold appliance, instrument, as a means to replace cable, it link directly to SCM or CPU,it enable wireless data transmission by plug and play.RS485 Bluetooth adapt have one master part and one slave part, they must use as a pair. When correctly connect the RS485 adapt, when you power up you device, the master and slave adapt will establish a link automatically, after this process you can use the Adapt as a serial port line.
The RS232 adapt can also use independently .if the user connect to a slave adapt of RS232, and other Bluetooth device paired with this RS232 adapt, the Bluetooth device can establish a link to the RS232 adapt, and use it as a serial port line. The RS232 adapt offer a safety authentication service, when the user start pairing process, the paired Bluetooth device must go through an authentication process. If the pairing process is between a master and slave RS212 adapt, the pairing process will automatically done.
