Wiring Information for TTL
Interface The following wiring diagram shows the connections between the
Module and a Stepper Translator that requires a TTL Interface. The
5-volt supply to the TTL interface can be either internal to the
translator itself or a separate power supply selected by the user. This
design is probably the most sensitive to noise due to the single ended,
high-speed nature of the TTL device. For this reason, it should be
used only where the Stepper Translator is close to the Module, that is,
no more than five cable feet, in an enclosure that is well shielded
from EMI noise when the enclosure doors are closed.
