Rudder Angle Indicator Complete Set
(45C-0183/ RD-0183)
Manual
Ⅰ.General
High-precision angle sensor is applied to transmitter, generating digital signal output; RS422 NMEA
0183 format will be output by MCU, MCU employed in rudder meter will convert the digital signal and
drive the step electric motor inside, indicating corresponding ±0～45° rudder angle.
Ⅱ.Technical Parameters
Working Volt: DC22～32V（standard DC24V）
Working Temp: -10～60℃
Range: ±0～45°
Deviation: ＜1°
Anti-fog class: 35
Ⅲ.Installment and Commission
1. Install transmitter: connect the rod with transmitter, turn left and right of the transmitter, make sure
the meter indication comply with transmitter, if opposite, change the signal-output cable. Position
the transmitter by using mounting plate until the indication is correct.
2. 0 °check: place the rudder blade at 0 °, adjust the transmitter to 0 °(Note: the 0 °of rudder blade and
transmitter must be correctly checked, or the precision will be reduced); later, install meter and
connect the power(DC24V) cable(must be correct); next, connect the cables of transmitter to rudder
meter, blue for A﹢, green for B﹣, black for GND, red for 12v. Turn power on after finishing the
correct connection, the meter will display 0 ° (note: the 0 °has been checked，please don’t adjust it
again).
3. ±45° adjustment: place the rudder blade at full degree, check the meter and adjust the rod to make
sure the ±45° correct.
4. The 0 °of rudder blade and transmitter must be correctly checked, or the indication difference (left
and right) of the meter will be big.
5. CW/CCW and GND , if the pointer indicates opposite direction with
rudder angle, please connect CW/CCW with GND for one time, the indication will go with rudder
angle direction.
6. DIM: for the light adjustment, UP and DOWN; POWER: shows power on; WORK: indicates
communication is in process.

Summary

General Information

Technical Specifications

Installation and Commissioning

Transmitter Installation

Connect the rod to the transmitter, check alignment, and mount the transmitter securely.

Zero Degree Calibration

Ensure rudder blade and transmitter are at 0°, then connect meter and power.

45 Degree Adjustment

Adjust the rod to achieve correct ±45° indication at full rudder angle.

Directional Indicator Setup

Connect CW/CCW with GND if the pointer indicates the opposite rudder direction.

Indicator Functions

Describes DIM (light adjustment), POWER (power status), and WORK (communication status).

Troubleshooting

No Display or Light

Check power cable connection and ensure it is correct.

Light On, No Display

Verify 12V supply, WORK indication, and transmitter connection. Flashing WORK indicates a broken meter.

Incorrect Angle Rod Reading

Adjust the connecting rod to correct large or small angle differences between left and right.

Incorrect Zero Degree Setting

Check the transmitter's zero setting and correctly adjust the rudder blade and transmitter.
