Once a device is selected, the
Data to send in HEX
field becomes enabled. In the
above example, DVD-1 was chosen as the selected device (but a receiver connected to
sink equipment could have also been selected), meaning that a command sent to DVD-
1 will travel from the Network Controller to the Ethernet Switch, and from the
Ethernet Switch to the transmitter connected to DVD-1. That transmitter will then
send the specified data command to DVD-1.
Note that no RS232 feedback is sent to the Network Controller when sending an
RS232 command originating from the Network Controller in the direction of the
transmitter (to DVD-1).
When sending RS-232 commands directly from a PC to any transmitter or receiver, in
pass-through mode, this is automatically accomplished by the existing connection
between the transmitter and receiver. As such this connection must exist for pass-
through to operate.
IR Pass-through
Special note concerning IR pass-through. This functions in the same manner as RS232
pass-through above, but is limited in one direction, from receiver to transmitter to
control source end devices. Thus a connection between transmitter and receiver,
automatically establishes an IR pass-through from the receiver to the transmitter.
Note that IR commands sent from the Network Controller is not supported on the
500758.
