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.

1. Add a setting to the Settings Table:

To add a setting (consisting of Frequency, Data Rate, etc.) to the Unity 4000's Settings Table:
Type "ADDS location carrier data_rate fec_rate tag_site [program_num]", where:
• location is a value of 1 to 17 (16 on some receivers) indicating the desired setting number
• carrier is the frequency of the carrier in MHz
• data_rate is the data rate of the carrier
• fec_rate is either 1/2, 2/3, 3/4, 5/6, or 7/8
• tag_site is a value between 0 and 15
• program_num is the program number between 0 and 65535, or * for the first available

 
2. Delete a setting from the Settings Table:

To delete a setting (consisting of Frequency, Data Rate, etc.) from the Unity 4000's Settings Table:
Type "DELS location", where:
• location is a value of 1 to 17 (16 on some receivers) indicating the desired setting number

 
3. Select a setting from the Settings Table:

To select a setting (consisting of Frequency, Data Rate, etc.) from the Unity 4000's Settings Table:
Type "PERMCH location", where:
• location is a value of 1 to 17 (16 on some receivers) indicating the desired setting number

 
4. Retune the receiver to a new channel (frequency, data rate, etc.):

To manually and directly set the Frequency, Data Rate, etc.:
Type "PERM carrier data_rate fec_rate tag_site [program_num]", where:
• carrier is the frequency of the carrier in MHz
• data_rate is the data rate of the carrier
• fec_rate is either 1/2, 2/3, 3/4, 5/6, or 7/8
• tag_site is a value between 0 and 15
• program_num is the program number between 0 and 65535, or * for the first available

 
5. 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.
 
6. Tune a certain audio channel to a certain port:
• If you have previously configured the Preselect Tables:
• If you need to list the available choices, type "R CFG" to view the list of preselect labels and associated configurations.
• Type "CSEL x label" where x is the port number, and label is the label of the desired preset.
• You may also use the "SETAUDIO" command as described below.



---

NOTE: You cannot select a service to more than one port simultaneously.  Attempting to do so will REMOVE the selected service from the previous port, and move it to the currently selected port.

---

1. If you have not configured the Preselect Tables:
• Type "SETAUDIO port route [program] [atten]", where:
• port is a value of 1 to 4 indicating the desired port
• route is one of the following:
• S -- Stereo
• 1 -- Encoder Left input on Receiver Left and Receiver Right outputs
• 2 -- Encoder Right input on Receiver Left and Receiver Right outputs
• R -- Reverse Stereo: Encoder Right input on Receiver Left output,
  and Encoder Left input on Receiver Right output
1. program is the 3-letter name of the desired audio service. See the chart above for a list.
2. atten is the value in dB (from 0-14) of attenuation to apply to the audio.


7. Properly route a dual-mono channel:

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



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


8. 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.


9. 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.
   


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


11. 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 baud, parity, etc. changes to the Modem port (the same driver used for the Terminal port), changes will take effect when the receiver is rebooted UNLESS you change the mode of the ports at the same time (e.g. change a port from Printer mode to Terminal mode) at which point the changes will be effective immediately.
    To set the new parameters for the Terminal or Printer port, type "PC device baud parity" where:
    • device is P for Printer, or M for Modem.
    • baud is 9600 or 19200
    • parity is E for Even, O for Odd, or N for None.  Note: Parity must be set to N for the Modem serial port.
    
    
12. Set (or Unset) the Terminal serial port speed to be the same as the Modem serial port speed:

The Unity 4000 receiver has a mode whereby the Terminal serial port speed may be always set to 19200. The normal operation is to have the Terminal serial port speed follow the Modem serial port speed, which is configurable from either the front panel or the terminal. Changing the mode of the Terminal serial port, however, must be done from the Terminal itself.
First you must be communicating with the receiver. If the receiver's Modem speed is set to 9600 and you get no response when you hit "Enter" while connected to the appropriate serial port, it is possible that your receiver is configured to always be communicating at 19200. Change your terminal program to be 19200 and try connecting again. If you are successful, then it is likely set to have the Terminal speed always set to 19200. Here is how to change this mode:

Type "19200TERMINAL value", where:
• value is either 0 or 1
, where:
• 0 disables forcing the Terminal speed to 19200, allowing it to follow the Modem port speed setting
• 1 enables forcing the Terminal speed to 19200 regardless of the Modem port speed setting.
