Thanks for your quick response. However, I must respectfully disagree with your statement that synch cables and connectors will affect the synch voltage, since their DC parallel resistance is essentially infinite at the 10 volt level applied. As an example, I measured the parallel DC resistance of the synch cable included with the Digibee using a Megger Insulation Tester. With 50 volts DC applied, the resistance between the synch cable conductors measured ~5 Gigohms (e.g. 5x10^9 Ohms). Such a high resistance will obviously have no effect on the synch voltage. The only thing that would reduce the "open circuit" synch voltage is the parallel DC resistance of the camera (or remote receiver) synch switching circuitry, which must also be very high to avoid spurious triggering.
In any case, though not a big deal, your specification for the Digibee synch voltage would be more accurate if you stated "approximately 10 volts" rather than "less than 6 volts".
Best regards,
Gus
