I-7188EN converter is a bridge between the Ethernet and RS-232/422/485. After installing VxComm driver on the PC, users can create Virtual COM ports mapped to the COM ports of the 7188EN. The original software (based on COM port) can connect with remote RS-232/422/485 devices via the Ethernet without any modification. I-7188EN is the most cost effective method to combine your original serial device with Ethernet communication ability.
