C : Choose a link mode for the
WR-R11a/WR-R10.
Select [Wireless remote (WR) options] >
[Link mode] in the camera setup menu
and choose from the following options:
Option
[Pairing]
[PIN]
The camera connects only to devices with which it has
previously been paired.
•
As camera will not communicate with devices with
which it has not been paired, this option can be used
to prevent signal interference from other devices in
the vicinity.
•
Given that each device must be paired separately,
however, PIN is recommended when connecting to a
large number of devices.
Communication is shared among all devices with the
same four-digit PIN.
•
This option is a good choice for photography
featuring a large number of remote devices.
•
If there are multiple cameras present that share the
same PIN, the flash units will be under the sole
control of the camera that connects first, preventing
all other cameras from connecting (the LEDs on the
WR-R11a/WR-R10 units connected to the affected
cameras will blink).
