6.3.6 Line Format
Controls the format of the line item selected in Line Selector.
(No Connect, TTL, LVDS, Opto Coupled)
Note: In the GO-5000-USB, TTL and LVDS are not available.
6.3.7 GPIO
This is a general interface for input and output and controls input and output for trigger signals or
valid signals and pulse generator. By using this interface, you can control an external light source,
make a delayed function to input a trigger signal or make a precise exposure control with PWC
trigger.
