Data Translation DT300 Series User Manual

Appendix C

Digital Inputs and Counter/Timer Inputs
TTL-type inputs must have current limiting so that circuitry is not damaged when power is
removed. On all Data Translation PCI boards, current limiting is used to prevent damage in
this fault condition.
On high-speed clock inputs, a ground that is located in the connector next to the clock must be
connected as a twisted pair with the high-speed clock input.
