Schematic of bottom connector ???

Fab602 · 06-20-04, 07:48 AM

Hello.
Where can I find the schematic of the X5 bottom connector ?
I wonder if the serial port is physically different from the USB port, if the serial cable include any protocol/level interface for USB/serial(I'm sure it's not) or if the port is tolerant to any signal.
I wonder also if the power connector is duplicated on this connector, if audio signals are available and so on...
Any info welcome !
Fabrice, France.

Dell Axim X5 pinout

01 GND (shield), also on USB charger cable PCB
02 (completely unconnected on USB charger cable PCB)
03 +5.5V, also on USB charger cable PCB (red)
04 +5.5V, also on USB charger cable PCB (red)
05 +5.5V, also on USB charger cable PCB (red)
06 +5.5V, also on USB charger cable PCB (red)
07 +5.5V, also on USB charger cable PCB (red)
08 +5.5V, also on USB charger cable PCB (red)
09 (completely unconnected on USB charger cable PCB)
10 power (purple, which voltage??), completely unconnected on USB charger cable PCB
11 (completely unconnected on USB charger cable PCB)
12 leads to test pad on USB charger cable PCB, but unconnected?
13 leads to test pad on USB charger cable PCB, but unconnected?
14 SEL (black), also leads to test pad and further line on USB charger cable PCB
15 GND (shield), also on USB charger cable PCB
16 (completely unconnected on USB charger cable PCB)
17 (completely unconnected on USB charger cable PCB)
18 (completely unconnected on USB charger cable PCB)
19 (completely unconnected on USB charger cable PCB)
20 GND (shield), also on USB charger cable PCB

Bottom
01 unknown, almost unused (someone said it's GND (shield), but it's most likely NOT correct: since the Axim inside picture doesn't show the usual ground layer non-connection, but rather a small line connecting to it - it's some DATA signal!), also leads to unconnected test pad on USB charger cable
02 GND (shield), also on my USB charger cable PCB
03 GND (shield), also on my USB charger cable PCB
04 CTS (orange), completely unconnected on USB charger cable PCB
05 RxD (green), completely unconnected on USB charger cable PCB
06 DCD (yellow), completely unconnected on USB charger cable PCB
07 DSR (blue), completely unconnected on USB charger cable PCB
08 DTR (brown), completely unconnected on USB charger cable PCB
09 RTS (red), completely unconnected on USB charger cable PCB
10 TxD (grey), completely unconnected on USB charger cable PCB
11 GND (shield), also on USB charger cable PCB
12 unknown, unused? (no line seen on inside picture either), completely unconnected on USB cable PCB
13 unknown, unused? (no line seen on inside picture either), leads to big test pad on USB cable PCB
14 GND (shield), also on USB charger cable PCB
15 USB Device, Data - (white), connected on USB charger cable PCB (white)
16 USB Device, Data + (green), connected on USB charger cable PCB (green)
17 GND (shield), also on USB cable PCB
18 unknown, unused? (no line seen on inside picture either), completely unconnected on USB cable PCB
19 unknown, unused? (no line seen on inside picture either), completely unconnected on USB cable PCB
20 GND (shield), also on USB cable PCB

It is possible that either 12/13 or 18/19 are connected to USB host D+/D-. MediaQ 1132 has USB host functionality, so it would be strange it the pins wouldn't at least be connected to the expansion connector.
