Why are there special blue-banded sync cords designated as “for Digital”?
Nikonos protocol strobes do not operate TTL with most of the new digital cameras. These cameras may lock-up completely when sensing a standard strobe. These special 2-conductor sync cords allow our Substrobes to operate in manual mode and provide fractional powers when used with a non-Ikelite housing. Please note that 5-conductor #4104.6 and #4104.62 sync cords look similar, but should not be connected to non-TTL digital systems. These cords should only be used to connect Ikelite TTL Substrobes with Nikonos IV & V systems, film cameras in non-Ikelite housings, or compatible digital SLR cameras used with non-Ikelite TTL adapters & housings. Blue-banded sync cords that connect Ikelite housings to Ikelite strobes are 5-conductor to provide power to the TTL circuitry built into many of our newer digital housings. Older 4-conductor sync cords look similar but cannot provide the necessary power from the Substrobe.
