2. Features
1. General
analog resistive touch panel and can eliminate unstable data (voltage value) generated by
softly pressing it or some external noises coming into the circuitry. By the internal filtering
process, all of the pressed positions can be sensed with a high degree of accuracy and these
data are sent to your host system with serial communication (CRS1-656) or PS/2
communication (CRS1-685).

Continuously (When pressing the touch Panel, continuous data is being received.)
4 & 8 - wire resistive analog touch panel made by Gunze. 8 - wire is highly recommended.
