Digital inputs and outputs (I/O)
Description
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. The máximal operation frequency is 200 MHz. If the IO was configured as input a 50 Ohm resistor can be parallel connected to the input to avoid reflections, this is a solder option.
A pull down resistor can be populated in each channel if needed. The version 1 and 2 have a pull up resistor too.
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
Functions
Connect: connects all in/outputs and sets all parameters
Inputs:
"Mode": select the DIO standar.
"DO" : set the signal number which will drive the output, this signal can be set or clear
manually using the module "B_S.vi" (Bool to Signal).
"DI" : get the signal number of which drives this input.
Set DO: set the signal number which will drive the output, this signal can be set or clear manually
using the module "B_S.vi" (Bool to Signal).
input: "DO" : signal number or value.
Get DI: return the logic value of this input.
input: "DI": Logic value of this input.
Write Mode: Set the mode of the DIO.
input: "Mode" : TTL/LVDS

Discriminator, Comparators
There are two discriminator sub-modules.
The SU703 has 4 input analogue channels. The threshold and hysteresis voltage must be set through a DAC (MAX537). The discriminator output go to the back connector. This module has 4 LEDs too. All four analogue channels or a part of it can be used as TTL digital input/output. The threshold of the first channel can be set through the DAC or a Lemo connector, in this fall a solder jumper must be set.
The SU736 has two analogue input channels and two digital NIM output channels connected with the discriminator/comparator output. The threshold and hysteresis voltage must can be set through a DAC (MAX537) or through potentiometers, the user can select it with the help of smd solder jumpers.
