Menu Item Description
X: override forward id
• Used in testing and fault isolation
• Enter a “test or alternate” Forward ID to use during fault
isolation procedures. Resetting the HSD or cycling the
power cancels this function.
L: test LEDs
• Toggles the “Power ON” (LED 1) and ‘Fault’ (LED 2)
LEDs ON (A) and OFF (D) or returns them to software
control (X).
Y: explain hpa error
status
• Reports HPA status:
• Displays HPA OK when no error codes are
reported from the system’s power up test
• Displays HPA error code message if system’s
power up test fails
S
• Used to set the preferred attenuation for Honeywell
Combined Mode (HCM) operation to reduce the output
signal level of the HCM module.
R
• Displays the HCM module threshold parameters for the
RF:
• If the measured RF level is below this threshold,
the “RF low” bit is set in the HPA maintenance
word, which is then sent by the HSD control
processor to the Honeywell SDU.
