Product Introduction
GE S739DVR-RST1 is a digital video fiber transmitter designed for security and surveillance infrastructure. It transmits video and up-the-coax control signals over fiber optic links for extended-range deployment.This module integrates with GE’s fiber optic system architecture to maintain signal integrity across long distances. Proper earth grounding via the DC Common/Ground pin is mandatory for stand-alone enclosure installations to prevent signal degradation.
Installation & Configuration Guide
Preparation (10 min)
Review installation manual 11-0739DV-D. Verify fiber optic cable specifications. Prepare copper-based grounding conductor. Ensure earth ground point is approved and accessible.Removal (5–10 min)
Disconnect fiber optic cables. Remove DC power. Unplug coaxial video connections. Remove enclosure mounting hardware. Inspect connectors for damage or contamination.Installation (10 min)
Mount stand-alone enclosure securely. Connect fiber optic cables with proper bend radius. Connect DC Common/Ground pin to approved earth ground using copper conductor. Reconnect coaxial and power connections.Power-On & Test (10 min)
Apply power. Verify LED indicators. Check video feed at receiver end. Test up-the-coax control functionality. Confirm stable ground reference with multimeter if issues arise.
Troubleshooting Quick Reference
| Symptom | Probable Cause | Action |
|---|---|---|
| No Video Output | Missing Ground Reference | Verify DC Common/Ground to earth connection |
| Intermittent Signal | Fiber Bend Radius Exceeded | Check cable routing; maintain minimum bend radius |
| Control Commands Fail | Coax Connection Loose | Reseat coaxial connectors; verify pin integrity |
| Module Not Powering | Incorrect Voltage | Measure supply at terminals; verify polarity |
| Video Noise / Snow | Ground Loop | Confirm single-point earth ground; check shielding |
Dimensions, Mounting & Wiring Notes
- Mounting: Stand-alone enclosure with dedicated mounting points
- Grounding: Copper conductor from DC Common/Ground pin to earth ground
- Fiber Interface: Standard fiber optic connector (verify type)
- Coax Interface: BNC or equivalent for video/control
- Clearance: Allow space for fiber bend radius and ventilation
FAQ
Why does this module need earth grounding?
Stand-alone enclosure modules require earth ground reference for proper operation. Without it, you may experience signal loss, noise, or intermittent failures.Can I use any fiber optic cable?
Check the installation manual for specified fiber type and connector. Wrong fiber specifications will cause signal loss or complete failure.My video is noisy. Is the module bad?
First check your ground connection. Ground loops or missing earth reference cause most video noise issues. Only suspect module failure after verifying grounding.Is this compatible with S7739DV receivers?
Verify against the installation manual. GE’s fiber optic system has specific transmitter/receiver pairings. Check model compatibility before ordering.How do I test up-the-coax control?
Send a PTZ or camera control command through the coax line. Verify response at the camera end. If video works but control fails, check coax connector integrity.What if I lose the installation manual?
Contact GE Security technical support during business hours (Mon-Fri, 6 AM – 5 PM PT). They can provide documentation and troubleshooting assistance for the S739DVR-RST1.Can I hot-swap this module?
Power down before replacing. Fiber optic connections are sensitive to insertion while powered. Always follow proper shutdown and startup procedures.
