Default baud rate: 4800 or 38400 (check original manual – typically 4800 for GGA, RMC, GLL, VTG sentences).
Installing a Samyung SRG-1150DN is a straightforward process if you adhere to the manual's guidelines on cable management, grounding, and antenna height. Taking the extra time to seal connections and verify voltages during installation will save you hours of troubleshooting at sea.
Tip: Always keep the physical manual on the bridge. While digital PDF versions are available, having a hard copy is invaluable when your electronics go down and you need a wiring diagram immediately.

The Samyung SRG-1150DN is a GMDSS-compliant MF/HF radio transceiver with built-in DSC and optional NBDP functionality. Installation requires careful attention to power supply, antenna matching, and initial software configuration. Installation Requirements Power Supply: Requires DC 24V (
Current consumption: 2.5A during reception and 15A during transmission.
For IMO compliance, use an individual power supply like the SP-1250ADC. Antenna System: Frequency range: TX 1.6~27.5MHz; RX 500KHz~29.9999MHz. Input impedance: .
Maintain a safe distance from magnetic compasses: Standard Compass 2.4m; Steering Compass 1.5m. Environmental Conditions: Operating temperature: -15∘Cnegative 15 raised to the composed with power C +55∘Cpositive 55 raised to the composed with power C . Relative humidity: 95% at +55∘Cpositive 55 raised to the composed with power C Initial Setup Steps samyung srg-1150dn installation manual
Mounting: The unit dimensions are 288(W) x 312(H) x 166(D) mm, weighing approximately 8.5kg.
MMSI Entry: Input the 9-digit Ship’s ID via the SET - ID menu. Peripheral Connection:
Connect the SN-100 terminal if using NBDP (Narrow Band Direct Printing).
Optional components include the DPU-414 printer and SD-250 alarm box. System Verification:
Check for AC IN, DC IN, and DC OUT light indications on the front panel. Perform a transmission test using a dummy load (minimum 300W rated). Verify Auto output adjustment via the POWER SER setting.

This technical write-up serves as an installation guide for the Samyung SRG-1150DN MF/HF DSC Radio Transceiver. 🛠️ Pre-Installation Checklist Power Supply: Ensure a stable 24V DC power source.
Grounding: Prepare a high-quality copper strap for the main unit. Antenna: Use a 6m to 10m whip antenna for optimal signal.
Environment: Choose a well-ventilated area away from direct sunlight. 🛰️ Component Overview SRG-1150DN: The main transceiver unit. SN-100: The control unit/remote controller. SP-1250: Power supply unit (AC to DC). SAN-150: Matching antenna coupler. 📋 Installation Steps 1. Main Unit Mounting Fix the bracket to a flat surface using the provided bolts. | SRG-1150DN wire | Connect to (chartplotter) |
Maintain at least 10cm of clearance on all sides for heat dissipation.
Use the shortest possible path for the Grounding Bolt to the ship's hull. 2. Antenna Coupler (ATU) Setup Mount the coupler as close to the antenna base as possible.
Connect the Coaxial Cable (RG-213) from the main unit to the "TX" port. Connect the Control Cable to the 4-pin connector.
⚠️ Warning: Ensure the lead-in wire is clear of metal railings to prevent RF loss. 3. Wiring and Connections
Power: Connect the 24V DC cable; ensure the polarity is correct (Red+, Black-).
DSC Watch Receiver: Connect the dedicated DSC antenna to the "RX" port.
GPS Input: Connect the NMEA 0183 output from your GPS to the data port for automatic position reporting.
Grounding: Connect the main unit and ATU to a common ground point using copper plating. 4. System Initialization Power on the unit and check the LCD Display. Are you currently installing a Samyung radar
Enter the MMSI Number (Note: This is usually a one-time entry; verify carefully).
Perform a SWR (Standing Wave Ratio) test on several frequencies to ensure the antenna is tuning correctly. ⚠️ Safety Precautions
High Voltage: Do not touch the antenna or coupler during transmission.
Compass Safe Distance: Install the unit at least 1.5m away from magnetic compasses.
Lightning: Ensure the antenna system is properly protected against surges.
