LM300 Bluetooth Ethernet Serial Switch / Server

LM300 Bluetooth Ethernet Serial Switch /Server connects either RS232, RS422 or RS485 serial devices to an Ethernet LAN/WAN providing reliable communication via a virtual com port on the host PC. Using its own graphical management software application it installs a virtual COM port in order to pass data over a LAN/WAN port on a PC. Any host application can communicate with the Bluetooth Ethernet Serial Switch over the virtual COM port making the LAN transparent to the serial device and software running on the PC.

The LM300 Bluetooth Ethernet Serial Switch /Server has an LM Technologies LM410 20 Pin Plug & Play Bluetooth Class 1 Data Module + external RP SMA Antenna on its PCBA and it is this module coupled with LM Technologies own Multipoint connection firmware that has an AT command set and can support 3 simultaneous RFCOMM connections. When the Bluetooth module accepts data from 3 devices at the same time it shares its bandwidth between the connected devices. As most serial devices run up to a maximum of 921.6 baud rates this allows the module to lose only a fraction of any bandwidth that may be used whilst connected to a single device.

 

LM300 Bluetooth Ethernet Serial Switch / Server.

The Bluetooth Ethernet Serial Switch /Server can be configured as a TCP Client / Server or UDP. Bluetooth Ethernet Serial Switch / Server operates in Direct IP Mode, Virtual COM Mode and Paired Mode. For added security in Server Mode Individual Client Sessions are supported and management access is password protected.

The Bluetooth Ethernet Serial Switch /Server has a Bluetooth range of up to 1000m when unimpeded by obstacles and it’s this wide range that offers users a varied range of applications. Warehouses that use Bluetooth scanners can then communicate directly to a main network, ideal for stock taking and or labelling. Coupled with our LM048 Bluetooth Serial Adapter, it is possible to make a broad host of serial devices wireless e.g. label printers, tills and industrial machinery. The Bluetooth Ethernet Serial Switch / Server creates an ideal network solution, decreases clutter and increases safety within the work environment.

Current certifications are FCC, R&TTE CE, The hardware can be offered with or without Retail packaging and can be branded for your company.
