Notes:
1
Actual values of X, Y, Z, and H are recorded on calibration sheet.
2
Cable: twisted, shielded pair, polyurethane jacket.
3
Cable shield is not connected in the sensor.
4
B (EIA-485): also known as TX+ / RX+ or D+ as alternative for B (high for MARK i.e. idle)
5
A (EIA-485): also known as TX- / RX- or D- as alternative for A (low for MARK i.e. idle)
6
A and B are compliant with other VS legacy sensors with digital RS-485.
7
I.C manufactures of RS-485 parts use an incorrect (but consistent) A/B naming designation.
8
Sensor case connects to ground in the sensor.
Note: Due to continuous process improvement, specifications are subject to change without notice. This document is cleared for public release.
