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-770which is connected to the Ethernet and outputs via TP cable.

The example, illustrated in Figure 33, shows a Kramer room controller that is connected to the VP-770via the Ethernet. The DGKAT OUT connector on the VP-770is connected via TP to a DGKAT receiver. This DGKAT receiver connects to a display via HDMI and RS-232.

Figure 33: Port Tunneling

The room controller sends RS-232 signals over the Ethernet via a dedicated Tunneling port to the VP-770. The VP-770sends 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-770.
