SECTION 2
INSTALLATION
2.1 INTRODUCTION
This section contains information for unpacking, installing, and configuring the Interface, including power,
signal, and enable wiring, and rating power supplies. Installation also includes matching and connecting
the Interface to the Host Computer or Terminal.
2.2 UNPACKING AND INSPECTION
If the shipping carton is damaged or shows evidence of abusive handling, inspect the Interface for visible
damage including dents, scratches, etc. If the unit appears damaged, contact the carrier and RFID, Inc.
Sales or Customer Service Departments immediately. Keep the shipping and packaging material for the
carrier's inspection. RFID, Inc. will arrange for repair or replacement of the damaged unit without
waiting for the claim settlement with the carrier.
2.3 PREPARING FOR INSTALLATION
The power is provided through the Eurocard connector 64 pin DIN and signal connections are made
via a terminal strip on the printed circuit board. If the RFID, Inc. enclosure assembly is not provided for
the Eurocard, you must provide a Eurocard DIN connection with +5v on pins a1,c1, and ground on
pins a32, c32. To access the inside of the Model 2022E assembly, remove the end plates and remove
the printed circuit board assembly. The end plates may be removed by first removing the four corner
hex nuts on each end plate which secure it to the assembly. Refer to the Figure 2-1.
Following installation of all Reader wiring, the end plates should be reinstalled using the same screws.
The cable gland should be tightened to secure and seal the wiring.
2.4 POWER REQUIREMENTS
The Interface must be powered from a regulated power source (linear supplies are acceptable,
switching supplies are out of the question) having the following characteristics:
Voltage DC Voltage Range: 4.75 to 5.25 volts
Ripple: 100 mV p-p (max.)
Current Operating: 350 mA. (max.)
100 mA. (typ.)
RFID, Inc. can provide a power supply suitable for use with the Model 2022. The Interface should be
operated from a grounded supply that has the same ground reference as the host computer. The ground
reference used for the Readers may be of a different origin.
