Hello Jennifer, I'm sorry you are having these problems. Here are several notes:
1) If the camera stops responding when using external trigger, it usually means that all the PHP instances that serve requests are waiting for the event that never happens. You can telnet to the camera and run: killall -9 lighttpd lighttpd - the camera web server, that launches PHP instances, when you kill web server, it kills all the PHP instances, and then it gets automatically restarted. 2) Make sure that you first (or in the same command) start trigger output, then make camera listen to the external trigger. 3) The main thing - you need to make sure that the cable is correct, plugged in the correct connector (synchro connector is smaller than serial, so it can fit in teh wrong port). Can you send the photo of the cable? Is the "master" end marked? For testing you just need the "master" end of the cable, master camera should only work (not getting stuck) if the connector is plugged in. It is possible to make camera output a 5VDC output on the connector so you can check it with multimeter.

Instead the slave camera takes the parameters correctly. What it the problem? Kind regards, Jennifer
