Power Up-Please Wait/Ant Comm Error
Fault Description:
A “Power Up-Please Wait” or “Antenna Comm Error” occurs when the 24VDC operat-
ing voltage generated from the power supply (plugged into a standard 120 volt AC wall
outlet) does not reach the CPU board located in the Antenna (upper unit).
Possible Cause:
1. A power spike causing the antenna to lock up.
2. If serial number is between 10,000 to 12,000 then check to see what color the insu-
lation is on the barrel connector sticking out of the base of the antenna. If it is blue
in color then replace that first.
3. 24Volts DC operating voltage not getting to the CPU board in the antenna.
a. Bad IDB.
b. Bad coax cable from IDB to Antenna (cable that goes through roof of coach).
c. Bad rotary joint or rotary cable in antenna.
d. Bad RF box
e. Bad CPU/Gyro
Troubleshooting:
1. Reset the 24VDC power supply by unplugging it from the wall outlet. If you cannot
get to the power supply then you can turn off a circuit breaker so that the TracStar
display goes blank. Reapply the 24VDC power and check the display reading.
2. Check for 24VDC coming out of the coax cable that is connected to the outside of
the antenna. When doing this you want to turn the power off on the antenna, dis-
connect the coax cable from the outside of the antenna, then turn the power back on.
If not present then the fault lies with the IDB (In-Door Box) or the coax cable going
from the IDB “Ant” jack to the antenna on the roof of the coach. You can check for
24VDC coming out of the “Ant” jack on the IDB (a paper clip may be required to
get in the small hole on the “Ant” jack). Replace the IDB or run a temporary ca-
ble from the IDB to the antenna to isolate the fault.
3. If you have 24VDC at the coax connected to the antenna then the fault lies inside the
antenna. Remove the antenna dome (4 or 6 dome bolts). Check for 24 VDC coming
out of the coax cable screwed into the top connector on the RF box. You can also
try to bypass the rotary joint system by running the outside ant cable directly to the
top connector of the RF box (small black box) and then powering the antenna on.
You must power off the antenna immediately if it does power up and the display
goes into “scan align” so that the coax cable does not get pulled on or wrap around
the antenna. If this works then something is bad in the rotary system. If you still
have a “power up-please wait or antenna comm error” then the fault lies with the RF
box, RF box ribbon cable or the CPU/Gyro.
