ComNav 1101 Autopilot INSTALLATION 4 - 19
AD-10S Output
The 1101 Autopilot outputs AD-10S sentences. Like the NMEA
output, this information is transmitted at a rate of 10 times per
second.
When interfacing to equipment which is compatible with the AD-10S
gyrocompass inter face, AD-10S Clock corresponds to CLK-H, AD-
10S Data corresponds to DATA-H, and AD-10S Common
corresponds to both CLK-C and DATA-C. If your equipment does not
support CLK-H and DATA-H, it may still be possible to inter face to
the 1101 Autopilot System. Contact your ComNav dealer or the
factory for assistance.
Post-Installation Checks
Hydraulic Checks
If you have installed a ComNav Marine Reversing Motor Pump, a
Constant Running Pump or an Engine Driven Pump, there are
several checks that must be done during the first weeks of usage in
order to prevent poor or dangerous steering per formance. During
this period you must check for air or leaks in your hydraulic system.
Residual air in your steering system
Following the initial installation and bleeding of your ComNav pump,
some residual air may remain suspended in the hydraulic fluid.
During the first few weeks, this air will gradually bleed out through
the header tank or the highest helm pump and the oil level may go
down. Check several times and add more oil as required.
Leaking fittings or equipment
Following the initial installation and bleeding of your ComNav pump
continuously monitor the oil level of the reservoir or the highest
helm pump in your steering system and add oil as required. If this
condition persists, it may be an indication of leakage in your
steering system. Check all hydraulic steering fittings and equipment
for leakage.
