Host Communication
Host communication comes through the 9-pin female D-sub
connector. Both RS-232 and RS-422 standards are supported as
ordered from the factory or service center.

Power Requirements
Power comes in from 8 to 10 volts DC. The Fixed Reader uses
less than 2 amps. Intermec supplies 9 volts DC at 2.4 amps
from Intermec power supply, #351-066-001.
User I/O
A general purpose I/O (Input/Output) connector provides signal
lines in and out of the reader allowing monitoring and/or control of external devices or functions.
The connector for this i s a 13-pin female circular DIN. The
mating male connector you need f o r mating with this is a CUI
# SD-130, (one source is Digi-Key #CP-1013-ND).

Definition
Outputs and inputs have 12 volt transient suppression devices
to ground at the connector. Output s ignals are driven by
2N3904 NPN transistors (low level) with a 100 kohm pull--up
to +5 volts through a silicon diode, giving about a 4.3 volt high
level. An output can be pulled high from an external source as
high as 40 volts. This will however tend to pull the other outputs higher (through two 100k resistors). The low level will be
about 0.1 volt up to about 30 mA. The output low voltage will

climb higher as the sink current increases. There is no protection on this. You need to ensure that their load won’t require
thereadertosinkmorethan50mA.
Input signals should be 0 to +1.5 volt for a low input and +3.5
to +5 volts for a high input. Each input has a 1.1 kohm resistor
in series with clamping diodes, but only about 1PA is used until
the input exceeds the 0 to +5 volt input range. There is also a
weak (100 kohm) pull--up to +5 volt on each input.

Connecting and Getting Started
WARNING: FCC regulations limit exposure to
radiofrequency (RF) radiation. To comply with
these regulations, operators of this device must
maintain a distance of at least 20 cm. (8 inches)
from the cover on the antenna assembly (The
cover on the antenna is the dome shaped
surface). While the device is on, the operator’s
body and parts of the body such as eyes, hands,
or head, must be 20 cm. (8 inches) or farther
from the cover of the antenna assembly.
FCC regulations also require that the antenna
assembly of this device be installed in
accordance with the installation procedures to
allow the operator to comply with the limit.

Antenna Installation
Ensure that you read the above warning before installing the
antennas and using your Reader product.
Reader to antenna cable
Mounting bracket
Back view Front view
1. Review the locations where the Reader products need integrated. Ensure that you have careful considered the
safe distances for product placement for workers and any
other personnel that may get in the RF path.
2. Place the radio and antennas with cabling are easily accessible f or installation and troubleshooting.
3. Use the mounting bracket to attach the antenna to a
fixed surface.
4. Attach the antenna to one of the four antenna ports on
the back of the Reader.

The following illustration is an example of a typical Reader
installation.
EXAMPLE: Two Product Line Conveyers, showing two antennas
on each line. Two antennas in a crossing pattern
provide angular diversity to improve read capability
when tag orientation is unknown.
The frames for these stations are PVC tubing with RF reflective Mylar liner X2. Ensure that an eight inch (20 cm) distance
from the antenna assembly is maintained to limit people’s exposure to radiofrequency (RF) radiation.
WARNING: While the device is on, the operator ’s body and
parts of the body such as eyes, hands, or head,
must be 20 cm. (8 inches) or farther from the
cover of the antenna assembly.

Connecting the Antenna to the Reader
1. Connect the antenna cable to a port.
2. Connect an SMA reverse--sex SMA terminator (Intermec
p/n 345-004-001) to any port that does not have an antenna attached.

NOTE:
Antenna ports
Each port must have either an antenna or a terminator connected.

Problem
Doesn’t recognize tag
Solution
1. Check to ensure antenna is connected to jack on Reader.
2. Ensure Reader is connected to
your computer.
3. Ensure computer is plugged into
ac outlet and computer is turned on.
4. Ensure tag is within range of antenna.
5. Access the Intermec web site
http://www.intermec.com or
http://NorBBS.Norand.com to d ownload and run the diagnostic test utility PENNRFID.EXE.
6. Call Intermec Technical Support
800--755--5505 (US or Canada)
425--356--1799 (elsewhere).
Diagnostic PENNRFID.EXE Utility
Should your Reader fail to read tags, download the test utility
from the Intermec web site (http://www.intermec.com). This
utility PENNRFID.EXE is a self-extracting zip file that
includes installation instructions and a test utility to check the
operation of the Reader on a laptop or desktop computer. Refer
to the README.TXT file included in the zip file for
instructions on using the test utility.
Should the reader fail after running this utility, contact Intermec Technical Support and give them the error codes you observe. They will step you through further diagnostic troubleshooting.

Performance Specifications
Dependent upon operating conditions and demands expected. If
used in a normal office environment with good read conditions,
you could expect to read up to 30 tags per s econd. Tags located
too f ar away or in poor locations, with respect to interfering
objects, provides poor results.
