The DAQ card and perif boards all have termination. Would I need some
diode termination setup at the external clock source too? Or is having
it at the terminal devices sufficient?

SCSI is NOT voodoo. There are sound scientific reasons why there must be
*EXACTLY* three terminations involved in any successful SCSI chain: The
Termination at the Host machine, the Termination at the last peripheral
on the chain, and of course, the Termination of the chicken over the
chain, performed using a silver bladed knife on the night of moondark
