Using the VS-570N as a Wireless Master

The VS-570N offers optical wireless TTL and manual master ash modes, enabling you to set and control all

functions of your wireless slave ash units from the VS-570N. Three ash groups (A, B, and C) are available,

with independent control over all three groups. For example, you can set one group to TTL mode and another

to manual mode.

In wireless TTL master mode, the VS-570N lets you remotely control your slave ashes while maintaining

automatic TTL functionality. You can adjust EV for the master

and slave ashes from -3 to +3 stops, in increments of

one-third.

Wireless manual master mode enables you to remotely set

independent power output for each of your slave ash groups.

Power output is indicated onscreen as levels 1 through 8. Each

successive level halves the output from full power (1) all the

way down to 1/128 power (8) over an eight-stop range, as

detailed in the table below.
