VP-774AMP - Port Tunneling

9 Port Tunneling

The port tunneling feature lets you send and receive simple RS-232 signals

between a controller and a serial device via the VP-774AMP which is connected to

the Ethernet and outputs via TP cable.

The example, illustrated in Figure 37, shows a Kramer room controller that is

connected to the VP-774AMP via the Ethernet. The HDBT OUT connector on the

VP-774AMP is connected via TP to an HDBT receiver. This HDBT receiver connects

to a display via HDMI and RS-232.

Figure 37: Port Tunneling

The room controller sends RS-232 signals over the Ethernet via a dedicated

Tunneling port to the VP-774AMP. The VP-774AMP sends these signals via TP to a

display that is connected to the receiver. This way, control data can flow between the

room controller and the display device, tunneling through the VP-774AMP.
