1.1 Description

This document describes the features and operational characteristics of the RI-STU-TRDC-01 & -02
S6350 High Frequency Multi-Protocol Readers. The RI-STU-TRDC-02 reader is shown in Figure 1.
The S6350 Reader operates at a frequency of 13.56MHz and is compatible with both standard and
ISO/IEC 15693 Tag-it inlays and tags. This reference guide provides the details that are necessary to
properly interface and use the reader as a part of an integrated system.
In compliance with the ISO/IEC 15693 standard, a global open standard for optimal use under
different regulatory and noise environments around the world, the S6350 Reader allows for the
interoperability of inlays and tags from multiple manufacturers.

1.1.1 Programming Interface

The S6350 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-Tag-it reader serial communications are
accomplished within data packets whereby communications from the host to the reader are known as
requests, and replies from the reader to the host are known as responses. This communication
occurs at RS-232 levels using 57,000 baud, 8 data bits, 1 start bit, 1 stop bit and no parity. By
definition, the host is always the primary station and initiates all communication sequences. These
sequences consist of request/response pairs where the host waits for a response prior to continuing.
