|Subject:||[Paparazzi-devel] GPS Config and Telemetry cables|

I'm from Azores Islands at Portugal and I'm an Aeronautic Engineer.
I have a Tiny 2.11 board from PPZUAV and I'm trying to configure the GPS LEA-4P.
After installing the UART tunnel for direct access to the GPS I followed the steps from http://paparazzi.enac.fr/wiki/index.php/GPS#GPS_configuration_using_U-Center and http://paparazzi.enac.fr/wiki/index.php/GPS_CONFIG.
- 01 Install U-Center on Windows XP
- 02 Connect FTDI Cable + 8-pin Molex adapter to USB on your laptop
- 03 Install the FTDI driver
- 04 Connect 8-pin Molex to "serial1" on Tiny 2.11
- 05 On U-Center, set the Baud rate: 9600 and Port: COM3
- 06 Menu: Tools/GPS Config select the file to upload (LEA-4P file downloaded)
- 07 Click File >> GPS button to send the file to the GPS
I think the step number 4 is wrong, instead of "serial1" must be "DOWNLOAD". Right?
So the cable must be like mine:
TINY DOWNLOAD – FTDI
TINY RXD0 --- PC SERIAL RX (5V or 3.3V) (YELLOW)
TINY TXD0 --- PC SERIAL TX (5V or 3.3V) (ORANGE)
TINY GND --- PC SERIAL GND
By this way I can see in U-Center information from GPS. Satellites, coordinates, etc.
But I can't send the configuration file to the GPS. I get time out. I don't understand why.
Another question is about the cable adapter for the telemetry connected directly to tiny SERIAL port.
It's like this one http://paparazzi.enac.fr/wiki/index.php/Compiling#Installing_the_USB_Bootloader ? Or like the GPS one?
"Make up a wiring harness similar to the following. You may vary the details however this is a working solution:
TINY RXD0 <-- PC SERIAL TX (5V or 3.3V)
TINY TXD0 --> PC SERIAL RX (5V or 3.3V)
TINY RESET --> optional wired to ground through a pushbutton so you can reset
TINY P0.14 (SERIAL1-5) --> attach to ground, or wire through a pushbutton to ground
TINY GND --> PC SERIAL ADAPTER GND"
