Inputs:
     Program Enable, Output Enable, and Data Transfer
     Logic of inputs determined by output option.
For P-type units:
     Enable or TRUE: 11.0 to 28.0 VDC @ 13.5 mA max. or
     tied to Vs+
     Disable or FALSE: 2.0 VDC @ 0.2 mA max. or open
     circuit
For N-type units:
     Enable or TRUE: 1.0 VDC @-3.0 mA max or tie to Vs
     Disable or FALSE: 3.8V DC to 28 VDC Max @ -0.2 mA
     max. or open circuit
Data Transfer Input:
     0-24 VDC logic: Edge-triggered (i.e., data transfer on
     both rising and falling edges)
     Low-Level: 0 to 0.8 V @ 3.2 mA
     High-Level: 2.4 V @ 0.4 MA
     Minimum pulse width: 30 ps
     Timing: Depends upon the PC sync option selected
     from keyboard:
     PC Synchronization mode: Updates position output
     within 150 ps of a transition edge (LOW-to-HIGH, or
     HIGH-to-LOW) at data transfer input.
     Transparent Mode/Microfreeze: Output data is
     continuously updated at full speed.The data is latched for
     100 ps ±1 0% within 10 ps of a transition (HIGH-to-LOW
     or LOW-to-HIGH) at data transfer input.
