Power Setup Standard Connection

: Connect the battery to the rear socket using a DC 24V supply. IMO Compliance : For GMDSS-standard installations, use the individual SP-1250ADC power supply. Fuse Protection : Ensure a is installed in the power line. 2. Antenna & Grounding Transceiver Antenna

: Connection via the MF/HF ANT jack with 50Ω input impedance. Watch-Keeping (W/K) Antenna

: Use a separate antenna (e.g., KUM-803 whip) for the DSC receiver. : Securely connect the

terminal to the vessel's common ground to reduce noise and interference. MarineThai 3. Component Interconnection

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. samyung srg-1150dn installation manual

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.

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-). The Samyung SRG-1150DN is a 150W MF/HF DSC

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.

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. Option B: Flush Mount (Requires optional kit)

Lightning: Ensure the antenna system is properly protected against surges.

Is this for a new installation or a replacement of an older model?

Option B: Flush Mount (Requires optional kit)

Cut a hole in the dashboard according to the template (provided in kit).
Insert the unit from the front.
Secure with flush-mount clamps from behind.
Apply sealant around the bezel edge.

Example concise installation checklist (for quick reference)

Verify package contents and inspect for damage.
Choose mount location with unobstructed PTZ range and proper protection.
Run cables and install surge protection; do not power before cabling complete.
Mount camera, secure connectors with weather sealant where required.
Power camera (PoE or 12V DC) and confirm LED indicators.
Discover device on network, change default password, set static IP.
Configure video streams and PTZ presets; test remote access.
Update firmware if available; note firmware version in records.

2. Selecting the Mounting Location

Choose a location that meets these criteria:

| Requirement | Description | |-------------|-------------| | Clear sky view | No obstructions (radar, antennas, masts) above the receiver | | Distance from interference | At least 1 m away from VHF, AIS, radar, or inverter | | Stable & dry | Not in bilge, near heat sources, or where water pools | | Cable routing | Accessible path for NMEA 0183 or NMEA 2000 cable to your chartplotter/display |

Mount the unit upright with the connector facing downward (if specified in the original manual) to prevent moisture ingress.

Chapter 2: Selecting the Ideal Mounting Location

The installation manual dedicates significant space to location planning. Here is a practical synthesis:

Frequency Band Selection

The SRG-1150DN supports:

ITU Maritime Bands: Pre-programmed with ship-to-ship, ship-to-shore, and intership frequencies.
Open Mode: For non-marine HF (ham radio or land mobile—check local regulations).

Set your region (US, EU, or International) as per the manual’s geographical configuration menu.

DSC Test Call (Non-Distress)

Select a dedicated DSC test frequency (e.g., Ch. 70 for VHF; for MF/HF, use 2182.5 kHz DSC).
Input a test MMSI (if available) or request a "Test Call" from a coast station.
Send the call and verify receipt acknowledgment.

1. Before You Begin

SWR Tuning Procedure (Crucial)

After physical installation, follow the manual’s tuning sequence:

Connect a wattmeter/SWR bridge between the radio and the ATU (or antenna).
Key the transmitter at low power (25W) in CW or test mode (see manual for "Tune" function).
Press the Tune button on the SRG-1150DN. The internal tuner will cycle relays to find a match.
Confirm SWR ≤ 2.0:1 on all intended operating frequencies (e.g., 2182 kHz, 4125 kHz, 6215 kHz).
If SWR is >3:1, re-check your ground system—a poor ground is the #1 cause of high SWR on MF/HF marine radios.
