Purchasing a Cable

---

Through a partnership with another site, high quality USB cables will soon be available for use with Software One!

When these are ready for order, it will be announced here.

Building your own Cable

---

Please, don't attempt to build your own cable unless you are confident of your skills.
An improperly built interface could easily damage your Valentine One^TM!


Interface Schematic

The schematic image is large, and browsers will down-size it for display. For best results, save it to your hard drive and print it on one page using your favorite image-editing software.

Notes:

The V1 won't send out messages for the remote display unless it thinks the remote display is actually connected:

• If you are going to be plugging the interface directly into the V1 accessory port, WITHOUT a remote display connected too (using an RJ-11 splitter), then connect a 4K resitor between the 12V line and Data line. This will "fool" the detector into thinking that a remote display is connected.

• If you are going to be using the interface WITH a remote display and RJ-11 splitter, then DO NOT connect a 4K resistor between the 12V and Data lines!

Having BOTH the remote display connected along with the 4K resistor in the interface cable will result in only 2K of resistence between the 12V and Data lines, which would allow too much current to flow to the data line, potentially damaging both your detector and your remote display.
YOU HAVE BEEN WARNED!

Using a Radio Programming Cable

---

Any of the radio programming cables used for my other software should also work with Software One, if you build a small adapter. Of course, the information in the above section about the 4K resistor still applies.
See my radio interfaces page for more information.
