The length of the cable is 5cm. Fig 6 shows typical assembly for the<strong>SDR</strong>-<strong>Kit</strong>s ready drilled enclosure where VNA and USB-<strong>VNWA</strong> Interface PCBs are mountedwith the copper sides facing at a distance of 8.1mm.[ ] Reduce the 10 core flat cable provided to 9 cores using scissors.[ ] Identify the “stripe” denoting pin 1 on top left corner of the D9sub Male connector. whenlooking at the pins. Position the flat cable in this connector so the blue core is on the side(pin1) (see fig 6).[ ] Place connector in a Vice and whilst holding connector cable squarely aligned, press the clamponto the male connector by operating the Vice, until the rear clamp clicks in place.<strong>SDR</strong>-<strong>Kit</strong>s.net © 2009 by Jan Verduyn G0BBL <strong>SDR</strong>-<strong>Kit</strong>s & Thomas Baier <strong>DG8SAQ</strong> Page 17 of 23

D9sub IDC Connection cable assembled to suit<strong>SDR</strong>-<strong>Kit</strong>s ready drilled Enclosure. Distance between connectors is 25 - 30mmCable 2:Stereo audio cable – with 3.5mm stereo plugs at either end[ ] Cut 2 length of 7cm wire (not provided) and solder between the two stereo plugsprovided. Check with an ohm meter. Perfectionists may use screened cable however thisthis is not necessary. This short cable plugs into audio sockets of the two PCBs.Only after the USB-controlled <strong>VNWA</strong> has been fully tested, the USB_<strong>VNWA</strong> Interface PCB isfitted in the Enclosure.Instructions to be provided in the next version of the <strong>VNWA</strong> <strong>Assembly</strong> <strong>Manual</strong>Note it is recommended that the Printed Circuit board is directly soldered in thehorizontal zintec coated metal chassis.

USB-<strong>VNWA</strong> FaultfindingPlease consult the <strong>DG8SAQ</strong> USB-<strong>VNWA</strong> Helpfile.• USB Not recognized - Is <strong>DG8SAQ</strong> Driver properly installed?USB Enumeration consists of 3 stages: a) detection of USB Hub, b) detection of Atmega88Controller, and c) detection of PCM2900 Audio Codec.Please consult the <strong>DG8SAQ</strong> USB-<strong>VNWA</strong> Helpfile. “USB Troubleshooting Guide”• Are 12 MHz or 6 MHz Crystals Oscillating? Check with Scope with x10 Probe• Audio sockets connected with 3.5mm audio stereo cable?• Is the Soundcard in use by another application? CDROM etc• Is another USB device using the <strong>DG8SAQ</strong> driver connected to the Personal Computer ?
