58 VP-771 - 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-771 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-771 via the Ethernet. The DGKAT OUT connector on the
VP-771 is connected via TP to a DGKat receiver. This DGKat 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-771. The VP-771 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-771.
