Dear Ángel, *J15 - SYNC EXTERNAL (RJ14 telephone-style connector)*
Go to page: http://192.168.0.9/parsedit.php, then "External trigger controls" (there are tips for each parameter on mouse over). You can switch on internal trigger generator with a programmed period. For external triggering you need to configure GPIO[10] to receive the trigger signal - set TRIG_CONDITION to 0x200000. TRIG_CONDITION is a 22-bit register where 2 bits are used for programming each GPIO (from 0 to 11, e.g., TRIG_CONDITION[1:0] will program GPIO[0]) - MSB enables input and LSB selects active trigger signal level. Btw, 3.3V should be enough. If you want to generate trigger pulse from the camera, program GPIO[11] - set TRIG_OUT=0x800000 (same as in TRIG_CONDITION register - MSB enables and LSB selects level). And set TRIG=0x4. You can also try - http://192.168.0.9/sync.php?role=detect&channel=external- it will set GPIO[10] & GPIO[11] and you'll just need to set the TRIG parameter after.
