System Description
20221032 / E 5
CD100A Course Detector and CDI35
Course Detector Interface
The sensor and interface unit connects the AP50 system to a
magnetic compass. The AP50 provides excitation current for
CD100A and converts the analog sine/cosine signal to digital
two-wire format for the autopilot steering computer.
General NMEA Compasses
Any compass outputting a NMEA 0183 message with either
HDT, HDG, or HDM sentence can be connected directly to the
J50/J50-40 junction units or to the NI300X NMEA Interface. An
output of 10 Hz is recommended.
HS52 GPS Heading Sensor
The Simrad HS52 is a GPS compass that displays true heading
output with position, velocity, and rate-of-turn information. This
product replaces several vessel instruments in one compact
package (gyrocompass, GPS system, and speed input).
The HS52 comprises three components: the sensor unit, the
interface unit, and the display unit.
The sensor unit contains two GPS sensors and an inertial
element. This unit is to be mounted on the vessel mast. The
interface unit contains the main CPU and serial interface with
high-speed communication. The display unit contains a LCD for
navigation information and buttons for user control and
command. The interface unit and the display unit may be
mounted on the bridge. Refer to the HS52 manual.
Other Compass Models
GI51 Gyro Interface
This interface unit connects the geared synchro and stepper
gyrocompass and the 200p/NM speed log to the AP50 system.
Utilize the repeater signal output from the gyrocompass and the
pulse output from the speed log to generate a speed and heading
signal on NMEA format. GI51 is easily connected via Robnet.
1.9 Optional Equipment
A series of options are available for the AP50 system.
AP51 Remote Control
This portable remote control unit for AP50 with 7 m (23 ft.) of
cable can be used as a hand-held remote control or can be
mounted in a fixed bracket-mount.
