1. C-HDM-3DHDSDII mainly checks the audio channel in audio group 1&2 or 3&4. Please adjust DIP switch
pin 3 for setup.
2. Some HDMI equipped TV may not be able to decipher multiple channel audio, and therefore set DIP switch
pin-2 to ON() to get stereo audio work and then check if multiple channel support is available.
3. While DIP Switch pin-4 is set to OFF(), 3G Level B will be automatically converted to Level A.
4. C-HDM-3GHDSDI supports only audio sample frequency 48kHz.
5. While stereo audio is chosen, CH 1 & 2 of Group 1 or 3 are output.
1.7.1 Bottom Panel (DIP SWITCH)
A 4-pin DIP switch is used for user interface, and users can access this switch from the bottom of the unit.

composite, YC on/off etc.
1.7.2 EDID Learning
To learn EDID follow these steps:
- Turn off C-HDM-3GHDSDI and set the Pin 4 of DIP Switch to OFF
- Connect the TV/Monitor through HDMI port to C-HDM-3GHDSDI and turn on
C-HDM-3GHDSDI
- The LED of C-HDM-3GHDSDI will dim and light again, which indicates the EDID learning
