[Gumstix-users] RS232 conections

[<gs...@gm...>]

I am trying to communicate withthe gumstix using a RS232 com port. I
have made a device as per the gumstix schematic
http://www.gumstix.org/tikiwiki/tiki-index.php?page=UART_Schematics

I want to connect it to the Gumstix and have connected the signals
Y0_RXD to FFRXD (hirose pin 54)  and Y0_TXD to FFTXD (hirose pin 26)
Is this correct? I seem to get a 5.0 V signal on FFRXD
