Hi Brian. Taking the list concensus and confirming it on my recently arrived '5680A, the pinout is as follows:
1. +15V (1500mA cold: 800mA hot) 2. Gnd 3. Rb Lock (lock = low) 4. +5V (~85mA) 5. Gnd 6. 1PPS (high until Rb Lock goes low) 7. 10Mhz 8. RS323-RX 9. RS232-TX These pinouts are not consistant across the FE-5680A range, but seems good for the 'current batch' of cheap units coming out of china.
