5. ELECTRICAL INTERCONNECTION
This chapter reviews the steps required to electrically connect
the DF-150 with digital interface (SSi or BiSS-C).
The DF-150 operates has two operational modes:
(i) i. Absolute Position over SSi or BiSS-C: This is the power-up
default mode.
(ii) Configuration and setup mode:
This service mode provides access via USB to a PC running
Netzer Encoder Explorer application (on MS Windows 7/8).
Communication is via Netzer Communication Protocol (NCP) over
RS-422 using the same set of wires.
Use the following pin assignment to connect the encoder to a
9-pin D-type connector to the RS-422/USB converter CNV-0003.
