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 Ikelite SubStrobes to operate in manual mode and provide fractional powers when used with a non-Ikelite housing.

These cords should be used for most digital camera installations in non-Ikelite camera housings with Nikonos bulkheads: Nexus, Seacam, Aquatica, Sea & Sea, Subal, et al. The Manual Controller can be utilized in conjunction with these sync cords to provide 10 power settings in half-stop increments with any DS model SubStrobe.

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.

Use of Ikelite TTL adapters with compatible non-Ikelite digital SLR systems requires #4103.51 and #4103.52 digital sync cords identifiable with their blue band.
