Connector Pin-Out

[Guest Rob_Quads]

In a bid to develop a proper hands free kits I was wondering if anyone had the details on the pinout of the connector on the base of the SPV?

I have found the following for the XDA (which I suspect will be virtually the same) but was just looking for some confirmation

Pin 1: CAR_MIC_IN (Car microphone input)

Pin 2: GND (Ground / chassis)

Pin 3: CAR_AUDIO_R (Car audio right output)

Pin 4: CAR_AUDIO_L (Car audio left output)

Pin 5: GND (Ground / chassis)

Pins 6-11 are all serial RS232 connections:

Pin 6: RS232_DCD

Pin 7: RS232_CTS

Pin 8: RS232_TXD

Pin 9: RS232_RTS

Pin10:RS232_RXD

Pin11:RS232_DTR

Pin12:NC (No connection)

Pin13:USB_VDD (USB voltage detection--detects USB connection)

Pin14:UDC+ (USB data positive voltage)

Pin15:UDC- (USB data ground/negative)

Pin16:GND (Ground / chassis)

Pin17:GND (Ground / chassis)

Pin18:GND (Ground / chassis)

Pin19:CAR_ON# (See notes below)

Pin20:V_ADP (+5 volts DC to charge/power the unit)

Pin21:V_ADP (+5 volts DC to charge/power the unit)

Pin22:V_ADP (+5 volts DC to charge/power the unit)

In this photo, Pin 1 is on the left:

Pin 19 "CAR_ON" notes: This puts the XDA into "car" mode, and there are actually two such modes. One is activated by the OEM car charging cord, which puts +5 volts on this line, and causes the XDA to dial/answer in "speakerphone" mode automatically. I have not tested this, and some people report it does not work while others say it does. The other mode is activated by grounding this pin. It turns off the built-in speaker/microphone, so only the connector speaker/mic is used. You do NOT need to enable this to make the connector speaker lines work, however.
