No. Command Function
24 Check Input Voltage Checks the tuner AGC voltage, external Slow_SW input voltage
OK : Both check are OK, NG : Both check are NG
* The IRD has to be set to the initial state, and 6V or 12V has to be applied from outside.
25 Check High Band (22kHz) Checks the oscillation circuit in the IRD
22kHz pulse is carried from the antenna input
26 Check LNB DC (18V) DC18V is carried from the antenna input
27 Check LNB DC (14V) DC14V is carried from the antenna input
28 Check MODEM(SET) Checks the communication between the MODEM in the IRD and External MODEM.
(Refer to the Appendix Page 71.)
OK : Communication check is OK, NG:Communication check is NG (Use DC OFFSET JIG)
