SU700

This module has 5 independent 3.3V TTL input/output, each of this IOs is provided with a LEMO connector. The signals can be configured as input or output through a FPGA register. Each channel can drive current up to 60 mA, in this way a 50 Ohm terminated cable can be use to avoid reflections. Meter la frecuencia máxima de conmutación. If the IO was configured as input a 50 Ohm resistor can be parallel connected to the input to avoid reflections, this can be done through a FPGA register.

A pull up resistor can be populated in each channel if needed. In this function mode the 50 Ohm resistor must be not connected.

The submodule contains 5 LEDs, witch are direct connected to FPGA outputs, the LEDs can be configured through internal registers.

LabVIEW Vi

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!

The meaning of almost inputs and outputs of this Vi depends on the input "Function". The global inputs and outputs does not depend on the "function" input.

Glogal Inputs

DIO#: number of digital input/output to be accesed (1..255).

USB In: Handle to the LogicBox (create by open.vi), if not connected will take a global. parameter, this only works with one LogicBox at a time.

error in: error handling input

Global Outputs

USB out: Handle to the LogicBox.

error out: error handling output
