1. INTRODUCTION
The JI-820 is a flexible, easy-to-use, PC cont olled inst ument designed to p ecisely emulate the
function of a wide va iety of inc emental encode s. It p ovides the design, system, o test enginee
with a tool to accu ately emulate encode signals gene ated by motion cont ol and indust ial
monito ing systems. Va iable encode pa amete available to the use include cycles pe evolution,
cycle f equency, A/B signal phase, Z signal position and pola ity, signal amplitude, and selectable
signal inte face. An intuitive Windows application manages inst ument setup and cont ol.
Communications and unit powe is all p ovided via a USB 2.0 connection.
