NOTICE
1. Power off AT-3GSDI500 and set the pin 4 of DIP switch of AT-3GSDI500 to OFF [ ].

3. The Lock LED on the AT-3GSDI500 will dim and light again, which indicates the EDID learning process is

1. In HDMI TH bypass mode, users must be aware of that the jitters coming from HDMI TH sources, such as DVD
players, may be much higher than typical requirement according to SMPTE request on HD-SDI signals. This will
result in SDI output with high jitters or even no SDI outputs!
2. Due to the high frequency bandwidth and low jitter requirement of 3G-SDI signals, for single SDI output
case, it is strongly recommended to use one 75 ohm terminator for the unused SDI output to keep the best
performance.
