Description
This module family consists of 8 LVDS digital input output (DIO). As connector is used two RJ45, so the user can use a standard patch cable to send/receive information. We recommended to use a cat5e cable or superior. This DIOs can be used to transmit a clock or signals in noisy environments.
Version 0
This version has to group of 4 channels, you can populat each group as input or output. If the transceiver and receiver of one group are populated, you can dynamically set up the group as input or output, but the driver will use only the half voltage.
sender ic : SN75LVDS391PW, speed up to 200 Mbps, typical output voltage 350 mV @ 100 Ohm load (for more details see datasheet)
receiver ic: SN75LVDS390PW, speed up to 200 Mbps, detects 100mV (for more details see datasheet)
Version 2 (and version 1)
The version 1 will not be produced any more, the only difference with the version 2 is that the version 1 is not pin compatible with the base board DL701 and DL706, due the use of the pin 34 of the back connector. The version 2 is compatible with all base boards. Other difference is that the version 2 has an optional oscillator.
This version has three main difference respect the version 0. The first one is that now the 110 Ohm resistor needed to use a DIO as input is external. The user has to put it in from the resistors parking lot. The second one is that now there is 4 groups of two DIO. The last one is that you can populate an oscillator which is connected to the DIO number 5.
The following integrated circuits are used in this board:
sender ic : SN75LVDS391D, speed up to 200 Mbps, typical output voltage 350 mV @ 100 Ohm load (for more details see datasheet)
receiver ic: SN75LVDS390D, speed up to 200 Mbps, detects 100mV (for more details see datasheet)

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

"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).

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.
