[Elecraft] K3 cable w/ARI500/ALS1300

[Joe Subich, W4TV]

The ARI-5000 does not have pull-up resistors on the "band data" lines.
The K3 will require either the "Ext Band Data Mods" or the updated
KIO3 Digital/Remote I/O board if the K3 was shipped prior to 10 Dec
2008 (S/N before approximately 2362).  See:
    http://www.elecraft.com/K3/mods/K3ALCMod_Rev_B.pdf

With pull-up resistors installed on the KIO3 Digital/Remote IO board
(or on pins 4,5,6 & 7 in the ALS-500), the cable can be similar to
the one designed by N0SS for the K3 and Quadra or FL-7000. See:
    http://www.n0ss.net/k3-to-quadra_08jan2010.pdf
    http://www.n0ss.net/k3-to-fl7000_25aug09.pdf

The connections are:
       K3 ACC              ARI-500 RJ-45
    --------------------------------------
         5       ground         1
        13     Band Data A      7
         3     Band Data B      6
         9     Band Data C      5
        14     Band Data D      4
        10     Key Out/PTT      2

TX Inh and +13V are not used by the ARI-500.
