Double Sync Cord SC-100
The Double Sync Cord lets you use two Speedllghts
for TTL flash (matrix balanced fill-flash, center-
weighted TTL flash) operation.
—Manual flash mode only is available when used with the Nikonos IV-A
connected.
• Caution
•The combined guide number for two Speedlights firing in the same
direction can be calculated as follows:
Combined GN = V(GN1f+{GN2y
where GN1 and GN2 represent the guide numbers of each Speedlight
used.
•Attach a wide adaptor when using the SB-102 or SB-103 for close-up
photography.
• If you want to use just one of two Speedlights attached, use the
Speedlight connected by the black cord.
—If the power switch on the Speedlight connected by the black cord
is turned OFF, the flash fires at full output instead of TTL automatic
flash. The camera's shutter speed cannot be switched automatically
to the sync shutter speed.
