1. Introduction
RMV-762D-TCP is a Modbus TCP/RTU gateway. It exchanges Modbus command from Modbus TCP/RTU
master to Modbus RTU/TCP slave. Modbus TCP command can be transceived not only Ethernet port but also
Wi-Fi interface. It supports Vxcomm and Point-to-Point connection. Users can choose Ethernet mode or Wi-Fi
mode to do the Point-to-Point connection, which provides TCP data tunneling between two serial devices.
The RMV-762D-TCP built-in Wi-Fi(802.11a/b/g) function can be applied to the already Wi-Fi system. It can
connect to the remote equipment by Wi-Fi AP to reduce the wire cost. The RMV-762D-TCP built-in Wi-
Fi(802.11a/b/g) function can be applied to the already Wi-Fi system. It can connect to the remote Modbus
equipment by Wi-Fi AP to reduce the wire cost.
Another feature, the RMV-762D-TCP provides the Limit-AP mode. That can provide the Wi-Fi AP to the Wi-
Fi client device..
In addition, the RMV-762D-TCP has a Powerful Function, Point-to-Point connection, to upgrade the original
serial application to network application.
