[arm-allstar] Allstar Remote Base Kenwood TM-V71

[Doug Crompton]

Kevin,

Virtually all amateur radio manufacturers have standardized on the Mini Din 6 pin connector for data connections. Radios from Icom, Yaesu and Kenwood use the connector. 

The V71 uses the mini DIN. I have attach a page from the V71 manual showing the pinout. The cable would be a little hairy for most to fabricate on the radio mini DIN side so here is a link for a quality cable from Digikey with a min DIN 6 pin connector and 6 foot cord with bare leads.

http://www.digikey.com/product-search/en?keywords=839-1051-nd

It is $8.39 plus shipping.

You could also use an old PC mouse or keyboard cable as long as it had the right pins wired. You would have to ohm it out.

If you are interested in interfacing Allstar (or other data modes) you should have at least one of these around because at some point you will probably need it. So if you are ordering it might be a good idea to order more than one.

Here is a data sheet on the digikey cable -

The connections are standard but every manufacturer labels them differently. Here is the connections for the DMK URI -

URI         V71
------------------
  1             3   - PTT
  8             6   - COS
  19,20      2   - GND
  21           5   - RX Audio
  22           1   - TX Audio 

The 1200/9600 baud outputs can be confusing when using audio. The 1200 baud output is de-emphasized so no software de-emphasis in Allstar would be needed.

Using the 9600 baud output would require de-emphasis to be set to yes.

It is likely the COS output is active high - so   carrierfrom=usb   should be set in simpleusb.conf.

> I am endeavoring to interface a Kenwood TM-V71 to Allstar, however, only see information for the TM-G707.  I would assume the serial instruction set is similar, if not the same.  Has anyone successfully interfaced the V71 as a remote base?  If so, how did you accomplish the same?
