Installation

Unpacking the Board

You should place the XSV Board on a non-conducting surface.

Configuring the Jumpers

Place shunts on jumpers J23 and J24.

Applying Power

You can supply the XSV Board with power in two ways:

1. Attach an ATX PC power supply to connector J11.

2. Attach a 9 VDC power supply with a 2.1mm, center-positive plug to jack J12. The

power supply must be able to source at least 1A.

LED D2 will glow when the power is on.

Connecting to a PC

One DB25 connector on the 6-foot cable should be attached to connector J10 on the XSV
Board and the other end should plug into the parallel port connector of a PC.

Setting the Oscillator Frequency

The XSV Board has a programmable oscillator which provides a clock signal to the FPGA
and CPLD. The oscillator has an internal 100 MHZ frequency source that is scaled by a
divisor between 1 and 2048 to generate the clock signal for the rest of the XSV Board.
The divisor is stored in non-volatile memory in the oscillator chip so it will be restored each
time power is applied to the XSV Board.

The divisor is set as follows:

q

Remove power from the XSV Board.
