over air providing true Serial Cable replacement solution.
This functionality allows serial printers using DSR or CTS
line for error reporting such as “Out of Paper”, “Printer
Offline” etc.
Supports Bluetooth Serial Port Profile (SPP) and Generic
Access Profile (GAP).

Overview
Data transfer made easy with the world’s smallest RS232 Bluetooth adapter. This adapter provides RS232 cable replacement for
devices which use RTS/CTS flow control or DTR DSR handshaking.
The LM048v2 can be powered from RS232 Pin No.9 (4v-13v) or from Mini USB Port via the AC mains adapter or Mini USB-USB cable.
Our new patented firmware replicated all RS232 control signals (DTR, DSR, RTS, and CTS) to transfer over the Bluetooth link. Unlike
other Bluetooth serial adapters in the market, a pair of LM048 adapters with their unique hardware and firmware combination, can
act as a true straight or twisted serial cable solution.
LM Technologies® provide an application called LM149 Configuration Software, which allows easy configuration of these adapters.
LM Technologies® also provide an option to configure the adapter from a console using an in-built menu system. This option may be
required for a device which only has a keyboard and screeen, such as a cash register.
