Title: Complete Information For Audiovox CDM-8500 Connectivity.
Post by: Squirrel on Nov 29, 2004, 10:57
I felt bad for mouthing-off about the error in the diagram provided by our hosts here, so I researched the issue and can provide the following additional information.

Pin Out Of "FutureDial" cable #47
(Purchased from Radio Shack for $23 US)
"For Audiovox Models 8200, 8500, 8600
This cable set uses the PL-2303 USB to Serial chip,
RS-232 signal designations collected from the following web link:
http://www.laogu.com/down/pl2303.pdf

Pin One is on left, when looking into phone connector
with keypad facing "up" (away from the Earth - NASA).

Function - pin number - wire color

NC - 1 - nc
NC - 2 - nc
NC - 3 - nc
GND - 4 - shield
GND - 5 - shield
NC - 6 - nc
NC - 7 - nc
DTR - 8 - gray
DCD - 9 - violet
RI - 10 - blue
NC - 11 - nc
NC - 12 - nc
NC - 13 - nc
NC - 14 - nc
NC - 15 - nc
GND - 16 - green/shield
TXD - 17 - yellow
RXD - 18 - orange
NC - 19 - nc
CTS - 20 - red
RTS - 21 - brown
NC - 22 - nc

nc= no connection


From the powersupply supplied with the Audiovox CDM-8500VM,
the additional pin information...

nc - 1 - nc
(+) - 2 - (+)
(+) - 3 - (+)
nc - 4 - nc
(-) - 5 - (-)
pins 6 thru 22 nc

A "universal" driver for this cable that supplies "basic"
support (using BITPIM) for the CDM-8500VM can be found at;
http://www.futuredial.com/support/download/prolificdrivers.zip

BITPIM can be found at;

I used this cable to install an additional Ringtone following the information provided by this link;

Are the pin descriptions the device pinout, or what that pin should be connected to on the serial port?

This pinout does not work for me ( COM connections, Max232)

Really worked pinout (tested by me):

CMD8500
[ - - - - - - - - - - - - - - - - - - - - - - ]
22 1

18,19 - GND
4 - POWER ON
5 - Tx
6 - Rx
20,21 - Vbat+

1) numbers follow right-to-left (keypad up)

2) This is for flash only. For use as data-cable (in data|fax mode & modem)
you must connect pin 7 to ground (this is "cable detection" pin)

Renumber this pinout from left to right and you will got same pinout, except Tx/Rx are swapped. I don't know correct position of this signals, but I've included this information into document.
