Press the "F10" key after inputting the command number(s) to be transmitted to the IRD.
After returning to the initial screen, select "IRD CHECK" with the cursor key and press the Return key.
The screen for executing the command will be displayed. Pressing the Return key will execute the command selected at
"MAKE CHECK_STEP".
The following table shows a list of commands and their functions.
*1 : Functionalities which you can only check with the check_step file
*2 : Functionality which you can check more easily with the "IRD State Window F5" or with the normal IRD application menu
*3 : Command that is only used in production and by R&D

Transmits the command used for setting the parameters required for IRD tuning signals.
(To set parameters, press the function key F1 at the IRD Check Mode Screen.)
Same as above except the use of function key F2.
Same as above except the use of function key F3.
Same as above except the use of function key F4.
Used to check if the Tuner Bit Error Rate is OK or not at limited MPEG stream signal.
OK: Bit Error rate OK, NG: Bit Error rate NG.
Command that is only used in production and by R&D for hardware check (Measuring
time of Tuning or Scanning)
Checks the oscillation circuit in the IRD.
Check LNB power supply voltage.
Checks the DETECT terminal of the DSCR Card and BANK Card.
Check used to check if the DSCR Card is present and to check the communication with
the main microprocessor. OK: Communication check OK. NG: Communication check
Used to check if the Bank Card is present and to check the communication with the main
microprocessor. OK: Communication check OK. NG: Communication check NG.
Mutes composite video output (Recovers after 2 seconds).
Mutes all audio outputs (TV_SCART, RCA) (Recovers after 2 seconds).
Switches the video output to SECAM.
Switches the video output to Y/C separation output. Also switches the video output to
Sets the SLOW_SW (16:9/4:3 discrimination signal) to OFF (Low Level).
Sets the SLOW_SW to 16:9.
Sets the SLOW_SW to 4:3.
Sets the FAST_SW (RGB/Video switching signal) to ON (High Level).
Switches the SCART mode 5, 2, 4 and 1. (Refer to the very next page Fig 2)
Command to check the communication between the MODEM of the IRD and an external
MODEM, which is connected to the PC that runs the service program. OK:
Communication check is OK, NG: Communication check is NG * Use the DC OFFSET
JIG to get the correct line voltage
Command that is used by R&D
Command to check the communication between the Omega IC and the Modem Controller
Command which is not used anymore, only for older models
Checks the tuner AGC voltage and the external SLOW_SW input voltage. OK: Both
checks are OK, NG: Both checks are NG. * for the Slow SW input voltage check, 6V or
12V has to be applied from outside.
