Diagnostic cable

[madman12]

i read there is a serial method for loading the firmware to the SB5101.
can someone post a pic or schematic of this cable (Diagnostic cable). i don't want to go the jtag route unless i really have to. or is this the usb cable it comes with?

Thanks.

or you can make one from an old nokia dku-42 cable

Thank you very much!!!!
one more thing...
just so I'm clear; i just connect the cable to those 4 pins, or do i run it through a max232 chip?
if i have to do the chip can you please provide a schematic?

a usb ttl/serial cable has a max chip in it so no need for any other chip
