1.1 Description
This document describes the features and operational characteristics of the RI-RU1-001A-00 Series
7000 Ultra-High Frequency Reader as shown in
Figure 1
. The Series 7000 Reader operates at a
frequency of 915MHZ and is compatible with Tag-it UHF inlays and tags.
The reader provides nine coaxial connectors for supporting up to nine external antennas. Each
antenna plugs into its own connector on the rear panel of the reader. The reader can be configured
to read inlays in the following modes:
•
Collective or selective data to be read from a single inlay.
•
Collective or selective data to be read from multiple inlays without requiring sorting or unpacking.
•
Classes of inlays to be filtered according to user-defined criteria.
This technology employs an interrogation feature that enables applications to uniquely identify all
inlays in the scan field, without misidentification. It also uses a protocol that maintains a uniform per-
inlay scan time, regardless of the number of inlays in the scan field. The protocol provides a flexible
software application interface that can be customized to the specific needs of particular industries or
applications. This reference guide provides the details that are necessary to properly interface and
use the reader as a part of an integrated system.

Programming Interface
The Series 7000 Reader is designed to operate as a part of a host-based reader system, which
essentially relegates the reader to be a slave to the host. Host-to-Reader serial communications are
accomplished within data packets, which occurs at RS-232 levels using 57,600. By definition, the
host is always the primary station and initiates all communication sequences.
