DAC Circuit Board - User Guide

Connecting the Inputs

The main input connection to make is to simply connect the IDC 10-way header socket supplied at the end of the ribbon cable to the correct port on USB#1. The ports each have a 10-way header plug attached to the board, so you have just to choose the correct port and plug the socket onto the pins. Make sure you have the pins and sockets lined up correctly and press the socket down evenly - the pins are easily bent if sockets are not attached with care.

The second connection is from the correct control pin from Port C of USB#2. If you are doing this directly from the USB module, you will need to make up a 10-way ribbon cable with IDC socket similar to the one supplied attached to the DAC board. Then you must ascertain which strand of the ribbon cable is the correct one for the control pin you want. Having prepared the end of the strand, simply insert into the screw terminal labelled WR and secure.

If you are using our Intermediate Control Board (ICB) connection is much easier. Simply connect a suitable length of wire between the correct control pin output from the ICB, and the WR terminal of the DAC board.

Connecting the Outputs

Again this is simply done. If you are using our ICB, first locate the two input terminals for the correct drive on the ICB. Then simply connect a suitable length of wire between the GND terminal on the DAC and the 0v terminal on the ICB. Another suitable length is then connected between the OUT terminal and the WIPx terminal of the ICB.

If you are not using our ICB, then you need to make similar connections but directly onto you drive controller. The GND terminal should be connected to the GND or 0v input of the drive controller. The OUT terminal should be connected to the wiper or +ve terminal of the drive controller. Check in the instructions that came with your drive controller to make sure which is correct before connecting.
