Bluetooth USB Serial Adapter, BM2001 is a product that is developed, designed and
produced by Firmtech Co, ltd. (formerly BTnetworks Inc.). It is for replacement of
standard RS232 cable perfectly, with USB interface, so can be easily adopted for
upcoming industrial machines, which do not have legacy RS232 interface.
Security of Bluetooth wireless communication is very strong because it uses the frequency
hopping and 128bit encryption in 2.4Ghz frequency range.
Hardware setting is very easy and simple.
- The maintenance is very convenience.
- One pair of BM2001 will try to connect automatically whenever powered up.
It needs an installation of the USB device driver.
- Doesn’t need to install the application software.
You can choose various configuration with DIP Switch (In DIP-Switch mode)
- Set Baud Rate (1,200 bps ~ 115,200 bps)
- Set the Role as Master or Slave
- Select Mode: DIP-Switch Configuration mode or PC configuration mode
BM2001 does not required external power supply as it gets power from USB port.
