Understanding the DAPT
display
When connected properly, the DAPT initially displays the IFL
receive cable voltage on its LCD display, as shown in this
example (the actual voltage may vary):
Important: To see pointing values, as described below, you must
check the box labeled
Enable OPI Display on the appropriate
installation software screen on the installer laptop computer.
If the IDU is in receive pointing mode and you press the Advance
button (3), the display changes from IFL cable voltage to
COMM
Startup and then (automatically) to Mode and Value :
The mode is either 0 or 2:
•
0 – Receive pointing.
•
2 – Automatic cross-pol (ACP), manual or automatic:
– Manual – The value is dynamic; it changes constantly.
– Automatic – The value is static; it does not change.
You cannot change the mode from the DAPT; you can only
change modes through the laptop.
In all modes the value is a relative indication of signal strength. A
higher number indicates a stronger signal.
OPI
The OPI, P/N 1031393-0002 (Figure 45) is a portable repeater
that displays signal strength values during antenna pointing.
