1.1 Introduction

Escort Memory Systems' passive read/write system is a complete
family of field-proven read/write Radio-Frequency Identification
products. The system consists of RFID tags, reader/writers, antennas,
controllers, bus interfaces, and ancillary equipment. Tags can be
attached to a product or its carrier and act as an electronic identifier,
job sheet, portable database, or manifest. Tags are read and updated
via an Escort Memory Systems Reader/Writer, through any
nonconductive material, while moving or standing still. Escort
Memory Systems' LRP-Series long range passive RFID system is the
latest in our line of high performance, industrial RFID equipment. The
passive design of the LRP read/write system uses the RF field from
the antenna to power the tag, eliminating the need for tag batteries.
The LRP passive read/write system is designed to provide cost
effective RFID data collection and control solutions to automation,
item-level tracking, and material handling applications. The LRP
system uses the internationally recognized ISM frequency of 13.56
MHZ to both power the tag, and to establish a radio link to transfer the
information.The LRP2000 is specifically designed to work with LRP­Series passive tags, which provide 48 bytes of reprogrammable
memory, and LRP-SISO-15693 compliant tags which provide up to 8K
bytes ofreprogrammable memory.

1.3 FCC Compliance

This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

1.4 Changes and Modifications

Any changes or modifications to the LRP2000 not expressly approved
by Escort Memory Systems, could void the user's authority to operate
the equipment.

2.2 Instalation

Antenna Environment

Electromagnetic radiation and the presence of metal within the
reading field of the antenna affect the range of the LRP2000. Mount
the antenna to minimize the impact of these factors.

Installing the Antenna

Once a suitable location is selected for the LRP2000 antenna, the
structure should be securely bolted to the floor using the holes
provided in the base. The dimensions for the antenna bolt pattern are
shown in Figure 2.3.

Title

Figure 3.1 shows the front connector panel with the four strain reliefs
and the RF connectors. The controller ships with sealing caplugs in
the strain reliefs, which should be left in any unused location for an
environmental seal.

The four strain reliefs will seal around cables ranging in diameter from

0.12 [3.0 mm] minimum to 0.32 [8.0mm] maximum. The wrench flats
are [17mm].

locations of all internal terminal blocks needed for wiring the system.

CAUTION:

Internal Connectors

The controller contains ESD sensitive components.
Always observe ESD-sensitive handling procedures when
working inside the controller.

Terminal Blocks

The controller is equipped with removable terminal blocks to aid
wiring. The data terminals are all equipped with screw terminals which
accept AWG 28 minimum to AWG 16 maximum diameter solid or
stranded wire. The screws heads accept a 3/32 inch [2.0mm] or
[2.5mm] screwdriver blade.

3.2 Antenna Cabling

Figure 3-3. Antenna Connectors

Figure 3.3 shows the two antenna connectors at the base of the
LRP2000 antenna. Connect one end of the antenna cable assembly,
CBL-1475, to the antenna connectors at the base of the antenna.
Mate the connectors at the opposite end of the cable assembly to the
corresponding RF connector on the controller as shown in Figure 3.1.
The cable assembly has two different types of RF connectors, one
threaded TNC and one bayonet-syle BNC. The controller has one
TNC and seven BNC connectors. The BNC connector of the antenna
cable assembly must only be connected to the controller connector
shown in Figure 3.1.

Title

CAUTION:

LRP2000 Long Range Passive Reader/Writer

The antenna cables must be properly connected to both
the controller and the antenna at any time that power is
applied to the controller. Failure to properly connect the
controller to the antenna can cause damage to the unit.
Connecting the controller to any antenna other than the
LRP2000 Antenna can not only damage the controller, but
can void the operator's authority to operate the LRP2000.

3.4 Power Supply Wiring

Title

CAUTION:

The antenna cables must be properly connected to both
the controller and the antenna at any time that power is
applied to the controller. Failure to properly connect the
controller to the antenna can cause damage to the unit.
Connecting the controller to any antenna other than the
LRP2000 Antenna can not only damage the controller, but
can void the operator's authority to operate the LRP2000.

Back out the terminal screws on the terminal block of the power
supply and connect the spade lugs of Cable CBL-1474 to the
terminals according to Table 3.3. Strip 1/4 inch from the opposite ends
of the cable assembly and connect to the input power terminals
according to Table 3.3.

CAUTION:

Only after all internal connections are completed should
the LRP2000 Power Supply be connected to the AC
mains.

3.5 RS232 Wiring

The recommended cable medium for RS232 communication is
Belden part number 9941. Specifications for Belden cables can be
found at WWW.BELDEN.COM.

3.6 RS422 Wiring and Termination

In installations where long cable runs must be used, or in noisy
environments, RS422 is them communications standard of choice for
point-to-point serial communications. The recommended cable
medium is Belden p/n 3084A (dropline), or Belden p/n 3082A
(trunkline.) With a maximum baud rate of 38.4 kBaud it is generally
unnecessary to terminate the RS422 terminals to match the
impedance of the cable. The input impedance of the RS422 terminals
is ??? Ohms. This provides an functional impedance match at all baud
rates up 38.4 kBaud, the maximum rate supported by the LRP2000.

Title

NOTE:

The RS422 receiver within the LRP2000 controller has
failsafeprotection circuitry which eliminates the need for
any pullup or pulldown resistors on the RS422 lines

.

3.7 Ethernet Wiring

Figure 3-8. : The RJ45 Connector on the Optional Ethernet Mod­ule

.

Because of the narrow size of the strain reliefs on the LRP2000, the
standard RJ-45 connector cannot be inserted through the strain relief.
It is recommended to loosen the nut on the strain relief, feed through
the cable, and crimp the connector in place. After the connector is
crimped onto the cable, the cable can be connected to the Ethernet
module and the excess cable withdrawn from the unit before
tightening the strain relief. Escort Memory Systems recommends
stranded cable for Ethernet wiring in areas where the unit will be
subjected to vibration.

3.8 Digital I/O Circuitry

Both the Digital Inputs and Digital Outputs are optically isolated
circuits with no common path between any channel terminal and
another channel, or between any channel and the LRP2000 power.
Because they are independent and floating, the external wiring
controls their use. The inputs can be configured for sensors with a
PNP or NPN output. The outputs can be configured in a Sourcing or
Sinking configuration. The examples in Figures 3.11 through 3.18
show different connections for common input and output devices.

Inputs

The +IN terminal must be at a higher positive potential than the -IN
terminal for current to be sensed correctly. The voltage range is 4.5 to
30V between the +IN and the -IN inputs and the maximum current is
25 mA.

Outputs

The output is limited to 30Vdc when off and 500 mA. These are
maximum ratings. A device that operates at 200 mA may destroy the
output due to inrush current if that current exceeds 500 mA(e.g. an
incandescent light). The inductive "kick" (back EMF from a collapsing
magnetic field) when a relay is released can impose a voltage higher
than 30V and destroy the output transistor (use a backwards diode to
clamp the back EMF).
