1 I n t r o d u c t i o n
The RTS200 combines a HF / UHF RFID reader and a powerful set of virtual instruments (RF
Generator, Spectrum analyser) to provide a complete RFID tester, suitable for both laboratory and
production line test of RFID passive tags.
Both UHF and HF frequency ranges are covered, and some of the most widely used protocols are
included in the basic package. The unit can be upgraded for other current or future protocols by
means of a simple firmware / software upgrade.
This document describes the RTS200 interfaces and connections.

The hardware consists of an aluminium box with all the electronics inside, and connectors at the
front and at the rear of the unit. The external dimensions are shown below.
2 . 1 F r o n t C o n n e c t i o n s
There are two coaxial connectors at the front of the unit, for the Reception (Green) and
Transmission (Red) antenna sections.

The signals in this connector have some pre-assigned functions correspoding to the machine
interface in the online test operating mode. The functions are described in the following table.
Signal Function Notes
E2 Trigger Machine-> RTS200 signal to start the test. Configurable polarity
S1 Result Indicates TEST PASS or TEST FAIL conditions, according to
configuration
S2 EOT End of test signal. The RTS activates this signal after the test is
finished
S3 Delayed Result Same as result, delayed by a number of triggers
See the I/O port structure section for a description of the hardware interface, and the RTS200
User´s guide for the description of the operation and configuration of these signals.

3 . 4 E t h e r n e t
This is a standard 10 Base T connector. A Standard Cat V STP cable should be used. To connect
the unit to a single computer, either a cross-over cable or a hub (or switch) shall be used.
3 . 5 I n p u t P o r t S t r u c t u r e
The Input port in connector IN/OUT is opto-coupled, and has the following structure from the
electrical point of view.

The opto-coupler requires only 1mA input current to operate properly. The absolute maximum
rating is 0mA, so this value should never be exceeded, or the port will be damaged. The port will
be active with an external voltage of +5 to +24V applied.
3 . O u t p u t P o r t S t ru c t u r e
All the output ports in connectors IN/OUT 1 and 2 have the same hardware structure. They are
open collector, according to the simplified diagram.
Each port has a NPN darlington output, able to supply up to 500mA when conducting. The load
circuit has to supply its own voltage.
3 . 7 R F c o n n e c t i o n s
There are two 50 ohm RF connectors at the front of the unit for Transmission (TX) and Reception
(RX) antennas. The connectors are SMA, and have to be connected through low loss high
frequency cables to the corresponding RF connectors in the HF or UHF antennas.
The TX cable and connector are always marked RED, while the RX cable and connector are
marked GREEN for easy identification.
For best results, the antenna models HTP200, UTP200 and LTP100 have to be connected
directly to the RTS200 (not using cables), by means of SMA-SMA transitions (tubes) provided with
the antennas.
