Click here if you do not have a terminal connected or are not otherwise able to send commands real-time to the serial port of the receiver.

NOTE : The Terminal commands below are bolded, and in quotes to delineate the actual commands, with included spaces. The quotes are not a part of the command unless noted specifically. All commands should be followed with only a Carriage Return (CR), not a CR/LF combination.

  • List which audio channels labels are currently available on the Unity 4000:

  • To find out what audio channels are available on the Unity 4000, you need only query the receiver for an MPEG status.
      Type "R M" to get an MPEG report. In the screen that follows, there will be one or two lines under the "Audio Presence" header. Each of these three-letter codes is a valid channel designator.
       
  • Tune a certain audio channel to a certain port:
  • If you have not configured the Preselect Tables:

    1. Properly route a dual-mono channel:

    2. An audio channel may be encoded at the originating source as either a Mono signal or as a Dual Mono signal.  If the signal is encoded as Dual Mono, it may actually be a stereo pair, or it may have discreet (independent) audio on left and right inputs.  If you desire to utilize a dual-mono audio channel that contains discreet audio, you will have to select the appropriate Route setting when you select the audio channel.  As noted above, the following four choices are available:
       
      S
      Stereo
      Encoder Left input to Receiver Left output
      Encoder Right input to Receiver Right output
      1
      1 on Both
      Encoder Left input to Receiver Left output
      Encoder Left input to Receiver Right output
      2
      2 on Both
      Encoder Right input to Receiver Left output
      Encoder Right input to Receiver Right output
      R
      Reverse Stereo
      Encoder Left input to Receiver Right output
      Encoder Right input to Receiver Left output

      1. Type "SETAUDIO port route", where route is one of the 4 one-letter choices described above (S, 1, 2, or R).

    3. Properly route a mono channel:
      If the signal is encoded as a mono source, the receiver will output the same signal on both Left and Right outputs, regardless of the Route setting.


    4. Set the receiver label:
      You can change the default label on the front LCD screen to any 20-character label. To do so, type " SETLABEL "This is the new label" " and hit Enter. You must include the quotes in this command, or else it will only use the first word following the command and ignore the rest.

    5. Set up the receiver serial ports:
      You must reconfigure the serial ports' assignments from the front panel. Instructions are found here.

    6. Set up the printer or terminal baud rate on the serial ports:
      You may reassign the communication parameters for the serial ports via the Terminal. If you are making changes to the Modem port (the same driver used for the Terminal port), changes will take effect next time you disconnect and reconnect at the new speed.
      To set the new parameters for the Terminal or Printer port, type "PC device baud parity" where:
      1. device is P for Printer, or M for Modem.
      2. baud is 9600 or 19200
      3. parity is E for Even, O for Odd, or N for None.  Note: Parity must be set to N for the Modem serial port.
