Without the Ikegami BSF-300 manual, the DIP switches are incomprehensible. Here is a typical configuration guide based on the original documentation:
Switch 1: Genlock Enable
Switch 2: Termination
Switch 3 & 4: Output Standard
Switches 5-8: Output Mapping These allow you to change which signal appears on physical BNC output 1. For example, you can turn Output 1 from Black Burst to a continuous sine wave subcarrier. The manual provides a truth table for this mapping. ikegami bsf-300 manual
| LED/Code | Meaning | Troubleshooting | |----------|---------|------------------| | ALARM + CARRIER off | No triax connection | Check cable continuity, BNC center pin | | CAMERA off, CARRIER on | Camera not powered | Check camera’s power switch; measure +12V at camera end (pin 2 & 3) | | ALARM blinking | Overcurrent on triax | Short in cable or camera. Disconnect, measure resistance (should be >1kΩ between shield & center) | | VIDEO LED off | No video from camera | Reseat camera module; check lens cable; cycle power | | LCD shows "E-4" | Genlock signal missing | Apply Black Burst; check termination (75Ω) | Without the Ikegami BSF-300 manual , the DIP
Manual Solution: This indicates an unstable external reference. However, if the external reference is fine, the internal VCXO (Voltage Controlled Crystal Oscillator) has drifted. The manual requires you to verify the external reference level is between 0.5V and 2.0V p-p. If the level is correct, the VCXO tuning voltage should be between 2V and 8V at test point TP-5.
