External Trigger Output (non-isolated)

This signal is provided on a connector at the host-end of the Photic interface cable. It is a TTL type signal and is

used to provide a synchronisation trigger output pulse to the PC.

3.3 Switching on

The Photic Stimulator has an on/off switch located on its rear panel. When off, the flash output is stopped

immediately. The state of the switch is communicated back to the host PC if using a USB connection.
