LM048
Bluetooth Serial Adapter
Long Range Bluetooth Serial Adapter with inbuilt antenna.
LM048 is the world's smallest Bluetooth Serial Adapter for RS232 cable replacement solution. This is a Class 1 Bluetooth adapter with inbuilt antenna and can operate upto a range of 100m.
Our new patented firmware replicated all RS232 control signals (DTR, DSR, RTS, and CTS) transfer over Bluetooth link. Unlike other Bluetooth serial adapters in the market, a pair of LM048 adapters with its unique hardware and firmware combination can act as a true straight or twisted serial cable solution.
LM Technologies provides a PC application called LM149 Configuration Software to configure these adapters.
This device is interoperable with any Bluetooth device using Serial Port Profile, which includes our own
Bluetooth USB adapters.
LM Technologies Ltd also provides option to configure the adapter from console using an inbuilt menu system. This option may be required for a console device which has just keyboard and screen such as cash register.
These units are FCC, RoHS and RTTE certified.
