APRS functionality (firmware, TNC, TNC and GPS ports, etc) has been moved into
the control head. <BR><BR>Kenwood sells the head alone as the
RC-710. You can upgrade a TMV-71 to a D-710 merely by replacing
the TMV's oem head with the RC-710. Further the RC-710 can
be usedas an all-in-one self-contained APRS terminal (i.e. sort of a Ham Hud
package), by making TX/RX audio, PTT, and squelch connections with any 2M rig
. In this standalone mode (once you provide the 8 VDC power the
head requires), the controls for radio functions such as volume, squelch, PL
tone, etc don't do anything -- only the APRS/TNC-related menu items
function. <BR><BR>As a result, the serial port on the head is
exclusively for APRS-related TNC functions. <BR><BR><BR><BR>The
physically-identical serial port on the main chassis is exclusively for
radio "CAT" (computer aided tuning); i.e. programming frequency memories,
remote-controlling band, frequency, repeater offsets & tones, etc.
<BR><BR>The two 8-pin mini-DIN serial jacks (on the head, and on the main
chassis) have the same pinout as the serial ports on classic Apple Macintosh
computers (during the era before USB when Macs HAD serial ports!). A Mac
serial cable with a mini-DIN on one end and a DB9 on the other (intended
to connect non-Apple serial devices to a Mac) will work with both these
connectors. Around here, at least (southern California), you can
buy 8-pin-MIni-DIN-to-8-pin-Mini-DIN "Mac serial cables" at
large computer or electronics stores for USD $7-$10. Buy a 10-footer and
cut it in half to get two 5-foot cables with a molded-on Mini-DIN plug on one
end, and flying leads for your own DB connectors on the other.
<BR><BR><BR><BR>The 6-pin MIni-DIN "packet/data" jack on the main chassis is
identical to such jacks on many other Japanese ham radios of the last two
decades or so. It provides raw discriminator audio, de-emphasized and
squelched audio, TX audio in, PTT and COR/Squelch Indicator out.
Despite the misleading labeling of this as a "data" jack, THERE IS NO DATA (in
the sense of RS-232 or TTL level streams) HERE -- only tx and rx
AUDIO. Full details on this connector are in this document
