Page 5: Preliminary Information
Preliminary information This guide is designed to provide the most complete information the operator needs to correctly and safely install and operate the linear encoders with guided profile of the SMAG series that provide SSI interface and Gray output code. The SMAG sensors are engineered to measure linear displacements in industrial machines and automation lines. -

SMAG + MTAG SSI At each change of the clock signal and at each subsequent rising edge (2) one bit is clocked out at a time, up to LSB, so completing the data word transmission. The cycle ends at the last rising edge of the clock signal (3). This means that up to n + 1 rising edges of the clock signals are required for each data word transmission (where n is the bit resolution);... - Page 17 SMAG + MTAG SSI The output code is GRAY.

Page 18: Recommended Transmission Rates
SMAG + MTAG SSI 4.4 Recommended transmission rates The SSI interface has a frequency of data transmission ranging between 100 kHz and 1.5 MHz. The CLOCK signals and the DATA signals are transmitted according to the “EIA RS-422” standard. The clock frequency (baud rate) depends on the length of the cables and must comply with the technical information reported in the following table. -
