The original Micro Converter models (without the 3G designation) do not support HDMI to SDI timecode conversion. Only the newer Micro Converter 3G and 12G models have this feature.
Although I don't have a Timecode Systems Pulse to test with, this signal flow does work with other timecode generators I have tried such as a Tentacle Sync E and Timecode Systems UltraSync One:
HDMI signal (with embedded timecode) -> Micro Converter HDMI to SDI 3G/12G -> Teranex Mini SDI to HDMI -> XLR timecode output to timecode generator
A few things to keep in mind:
- Only the right XLR output on the Teranex Mini Converter supports timecode output.
- The Teranex Mini Smart Panel (with the LCD screen) is very helpful both for configuring the converter and for monitoring the incoming video signal format (and embedded timecode).
- If you don't have the Teranex Mini Smart Panel, I would recommend using the Teranex Mini setup utility software on a computer to configure the Teranex converter (this works either over USB or an Ethernet connection on the local network). The setup utility software is much easier than using the DIP switches for configuring the audio/timecode output settings of the Teranex Mini.
- With the standard faceplate the LED indicator should turn green if a valid input video signal is connected to the Teranex Mini (but you won't be able to know whether that video signal has embedded timecode).
- You may want to update the Teranex Mini to the latest firmware (using the setup utility) as it's possible that there were some updates that affected input signal compatibility.
- You'll need an XLR output adapter cable to connect from the Teranex Mini timecode output to the input connector of whatever timecode generator you are using. And you'll need to set the timecode generator to jam sync or timecode input/reader mode.
For the Timecode Systems Pulse, since it sounds like it only accepts timecode input through the 5-pin LEMO connector you will need an XLR female to 5-pin LEMO adapter cable. Timecode Systems sells the TCB-19 cable for this:
