The BM-2108E Serial to TCP/IP Serial Device Server is a bidirectional switching and 

transmission  device from serial port to Ethernet TCP/IP protocol. It changes the traditional           serial communication to Ethernet communication. It realized speed networking for serial device. 

The converter uses transparent communicate protocol, so that the user need not understand complex 

Ethernet TCP/IP protocol,   no need to modify old serial program
