PROCESSOR
(cont’d)
Configuration
No GPS or DGPS
•
Possible incorrect installation of the
AS110/AS105 splitter cables; they
may be reversed at the splitter for the
GPS and differential output ports
going to the 961XD processor.
•
For verification and troubleshooting of
the antenna system, see Table 3,
“Troubleshooting the GPS/DGPS
antenna installation,” on page 39.
•
The 961XD processor BIOS may be
improperly configured. This normally
wouldn’t occur unless the BIOS mem-
ory battery has failed or the BIOS set-
tings were intentionally changed.
Consult with the Northstar Service
Department for information on how to
troubleshoot and correct this problem.
DGPS
(DIFFERENTIAL)

screen, and:
The BEACON RX SELF-TEST AND SOFT-
WARE message says
FAILED
(p
ress the
STAR
key to access the SERVICE MENU
screen, then press the
GPS STATUS
key).
•
Wait 30 minutes after start-up (only if
a new unit).
•
Check for an open or shorted bea-
con-antenna cable connector.
•
Check for proper ground.
•
The Northstar 8410 ACI or the 961
processor may be defective; call the
Northstar Service Department.
