GW DEVICE SERVER…

Serial tunneling

A common application is simple point-to-point connection of two serial devices via an Ethernet network. The data is tunneled

through the network to remove any range restrictions, such as a maximum of 15 m for V.24 (RS-232). This connection also

operates across sub-networks and gateways. The GW DEVICE SERVER… at each end is logically linked to the other by

specifying the target and source IP addresses.

Serial tunneling

It is also possible to multiplex data from multiple serial ports on multiple GW DEVICE SERVER… servers to a single serial

port on a GW DEVICE SERVER…

Virtual COM port

Existing application software that only communicates via serial COM interfaces can be redirected to remote COM ports.

Virtual COM ports must be created on the PC that the software uses for communication. The virtual COM ports are physically

redirected to the network card and a destination IP in the network. There are two options for creating virtual COM ports: the

COM port redirector software, or the GW DEVICE SERVER… Windows driver. Both can be downloaded from

phoenixcontact.com.
