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.
eatures

4. SO TWARE INSTALATION
4.1 Software Installation
A USB d ive as well as JI-820 Cont ol softwa e will be installed on the host PC. Step-by-step
installation inst uctions a e as follows:
4.1.1 USB Driver Installation
a. Host PC with an Inte net Connection
1. Ensu e the host PC is connected to the inte net.
2. Connect the JI-820 to a spa e USB po t on the PC.
3. Windows will silently connect to the Windows Update website and install the
equi ed d ive (s). In some cases, this could take several minutes to complete.
4. At installation conclusion, ve ify that the f ont panel Powe LED is on.
Note: If the d ive s we e not automatically found o the JI-820 device has
not been added, continue to the “Host PC without inte net Connection” step
below.
5. D ive installation is now complete.
b. Host PC without Inte net Connection
1. Inse t the JI-820 USB Flash D ive (included with you JI-820 pu chase) into a
spa e USB po t on the host PC.
