USB Datalogger, SPI Mode trouble
I am having trouble getting my USB datalogger (P/N 27937) to start up properly in SPI mode. When I place the jumper in "SPI Mode" according to the MemoryStickDataLoggerV1.1.pdf document and apply power, the LED blinks once through its sequence (green, red, repeat for two seconds), but then the LEDs turn off.
When I place the jumper in UART mode the LEDs will flash red and green continuously.
I have not been able to communicate with the Datalogger in SPI mode, and was wondering if this behavior indicates a problem, or if this behavior is normal in SPI mode.
Thanks for any help,

Have you got this unit to work before and now it's giving issue, or when did you start encountering this continuous flashing in UART mode? Do you have a thumb drive in when the LEDs are flashing?

I attempted to place the device in UART mode, inserted a thumb drive, and then powering the device. Without writing anything to the device while in UART mode, the LED constantly flashes green then red.
Thanks for any help you can offer,
