Digital Input/Output. Support: SU700, SU701, SU703, SU704, SU706, SU707 According to hardware this supports either TTL,, TTL_coax, NIM or DIFFERENTIAL I/Os. Each connector can be used as either an output (DO) or input (DI) or both. If used as an input, terminal DO (driving output) must not be connected, as this enables the output driver and would override any input signals.
Please obey termination rules as defined for the specific used hardware!
Params: Mode: set according to used hardware module and level standards. (SU704 supports switchable 50 Ohm termination!) Debounce/ms: debounce delay for suppressing intermittent signals (1..255 ms). debounce=0 disables this function!
Function: Connect: connects all in/outputs and sets all parameters Set DO: change input DO Get DI: return output state at DI Write Mode: load appr. mode
DIO#: number of connector (must be unique!)
USB In and USB Out are related to the selected USB interface! No connection uses a global parameter, set by OPEN.vi!
