Using Your VS-510P as a Wireless TTL Slave
Groups:
With the VS-510P’s wireless system, you can assign remote flash units to any one of three groups (A,
B, or C) and set the mode and power ratio for each group.
Channels:
Master and slave flash units exchange data through channels. On the VS-510P, four channels (1, 2,
3, 4) are available. You can select the channel you prefer for communication between the master and remote
flash units. You can use this option to prevent your remote units from being triggered by the master unit of
another photographer working with the same type of system nearby.
Setting the remote TTL flash units:
To set a VS-510P flash unit to function as an automatic TTL slave, follow
these steps:
3. Make sure the master flash or controller on your camera is on and set to automatic TTL mode.
4. Select the appropriate group and channel on the master unit. Consult the master’s manual to find out how
to set it.
5. Make sure that the slave mode switch on the VS-510P is not set to S position.
6. Press the Mode button repeatedly to cycle through the mode options on the LCD. After the manual modes,
the following slave TTL (STTL) modes will be displayed: 1A, 1B, 1C, 2A, 2B, 2C, 3A, 3B, 3C, 4A, 4B, 4C.
