The WR-T10/WR-R10 Wireless Remote Controller units use radio frequencies to communicate; by pairing together a WR-T10 and one or more WR-R10 units. The WR-A10 WR Adapter is designed to work with the WR-R10 Wireless Remote Controller (transceiver), allowing it to be connected to select Nikon DSLRs with a 10-pin connector, to wirelessly control the shutter release. DSLRs without a 10-pin connector do not need the adapter. The WR-R10 can also be used to control Nikon radio-controlled flash units such as the SB-5000 Speedlight.
One WR-T10 unit can be paired with an unlimited number of cameras with a WR-R10 unit attached.
When the WR-R10 is used along with the WR-A10 WR Adapter to connect to select Nikon Digital Cameras with a 10-pin connector, one camera can be designated as “master” and control the shutter release of up to 64 WR-R10 transceiver units.
Range (line of sight) from the WR-T10 to WR-R10s is 66 feet (20 meters).
The WR-R10 can also be used to control radio-controlled flash units with the D5 and D500 DSLRs with firmware version 3.00 or later.
Connected to the camera using the WR-A10, the WR-R10 is easily paired with the SB-5000 Speedlights.
