Front panel
Connector: DSUB 37 connector, female
Buttons: Power ON-OFF
Emergency Boot
Trigger In:
TTL compatible Input Level, 1KΩ series resistor and fast ESD
protection. Rising Edge sensitive, required pulse width >75 ns
Trigger Out:
Output with TTL Level, series resistor of 82Ω and fast ESD
protection.
Output-Strobe pulse width: 500ns
Discrete IO: User definable Input/Output selection done by software,
Input High voltage 3.0V…35.0V.
Input Low voltage max. 0.8V
Output High voltage:
Internally driven min. 4V default,
Externally supplied: up to 35V max
Output Low voltage 0.4V max
Maximum Sink Current of each open collector 50mA
Please note: When the default 5V for the discrete outputs are
not used, provide a serial resistor in line with the open collector
transistor. If using a discrete pin as input, make sure that the
output mode is set to default before connecting an external
voltage. Otherwise the transistor can be damaged.
