RX Alarm: For power monitoring conditions, the RX alarm functions
the same as the TX alarm. For fiber switching situations, the alarm
will continue to sound even if the optical signal is restored,
indicating to the user the type of malfunction that has occurred. The
RX alarm must be manually reset with the SELECT/RESET button.
System Examples
The combination of Telecast’s DiamondBack video multiplexer and Telecast’s
Adder 161 Audio/Data multiplexer or Adder 882i intercom/Data multiplexer
provides a powerful network solution for carrying audio, video and data
economically from point to point. The Aux Input on the DiamondBack TX is
intended for a coaxial connection to the Adder 161 or 882i.
An example of the use of the DiamondBack and the Adder 161 is shown in
Figure 4. The Adder 161 can multiplex up to 16 channels of audio, 2 streams of
digital data, and 4 switch closures for delivery on its coaxial output to the
DiamondBack TX.
Figure 4: Example of the DiamondBack/Adder 161 Network
Figure 5 shows the use of bi-directional Diamondback2’s with the Adder 882i.
This will provide for up to ten 4-wire circuits or 2 4-wire circuits PLUS 4 dual
channel RTS signals or 8 single channel ClearCom signals.
