VP-774AMP - Port Tunneling 93

10 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 95 , 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 95: 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 .
