Digital Inputs/Outputs
Your Videum 4100/ 4400 features 8 digital input/output triggers that
can be used for event signaling. The 8 digital input/output interface on
the Videum 4100/4400 is controlled through Winnov’s ActiveX
software. Each Input/Output can be individually used as input or
ouput.
Please refer to page 6 to physically locate the eight digital I/Os on your
board.
Videum 4100/4400 driver supports interrupt driven status reporting of
the digital input/output ports. The inputs are 5 V tolerant even when
operated in 3.3 V mode. However, the logic threshold is lower in 3.3 Volt
mode.
