Turn on the power switch on the main unit, then press the power button on the Control Unit. Program the MMSI Number
Clean the copper ground strap contact point; verify antenna specs. High VSWR warning Damaged coaxial cable connectors
The manual specifies a minimum safety distance of from the antenna during transmission to avoid FCC radio frequency exposure limits.
Maintain : 2.4m for standard and 1.5m for steering compasses 2. Antenna and ATU Connection samyung srg-1150dn installation manual
: The user interface panel featuring the display and keypads.
: Select a standard marine MF simplex channel and press the [TUNE] key. The SAT-100 should stop clicking within 2–5 seconds, and a "TUNE OK" confirmation icon should display on the screen.
Connect a wide copper ground strap (minimum 50mm width) from the ATU ground terminal directly to the ship’s steel hull or copper ground plate. Turn on the power switch on the main
Default baud rate: or 38400 (check original manual – typically 4800 for GGA, RMC, GLL, VTG sentences).
Check antenna connections, cable damage, or improper antenna installation.
Mount all components at least 1.5 meters away from magnetic steering compasses to avoid interference. 2. Mounting the Hardware Main Transceiver and Control Unit Maintain : 2
Proper grounding is essential to prevent backward voltage damage and ensure stable transmission. Initial Configuration and Setup
The control head is splash-proof, but the main transceiver unit and power supply must be installed in a dry, weather-protected space (such as the bridge console or radio room).
Keep the connection wire between the SAT-100 output terminal and the antenna base under 1 meter to reduce RF radiation power loss inside the ship superstructure. Power Infrastructure and Wiring Diagrams
With the preparations complete and safety in mind, you can follow this checklist to make the physical connections.
Before mounting any hardware, choose installation locations that maximize performance while protecting the delicate internal electronics of the transceiver cabinet.
