Advanced Keypad Input - Accurate Technology ProScale 950 Series Operation

Advanced Keypad Input

This Function allows external activation of two keys on the
Advanced Key Pad.

position B to enable external inputs.
The multi-purpose external connector on the General Purpose Readout
provides a direct connection to IN1 (only). This allows for easy external
interfacing without modifying the case or soldering on the circuit board.
There are three solder pads on both Readout circuit boards, labeled IN1, IN2
and GND (the In-Panel readout connections are limited to circuit board solder
pads, no external connections.) Any two of the Auxiliary keys may be mapped
to respond to an external input by programming Pr35 and Pr36 using the Key
Function Mapping Table below.
The inputs must be from a normally open "dry" (no voltage applied) switch,
connected between ground (GND or common) and IN1 and/or IN2. The switch
input operates exactly the same as the mapped key providing both Momentarily
and
Press and Hold
CAUTION:. DO NOT APPLY VOLTAGE TO THESE INPUTS.
These inputs should only be switched from OPEN to GROUND.
