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, p/n: 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 con-
trol of external devices or functions.
The connector for this is a 13-pin female circular DIN. The
mating male connector you need for mating with this is an In-
termec p/nL 351-184-001.

9, 10, 11, 12, 13 GROUND though individual 10 ohm resistors
Outputs and inputs have 12 volt transient suppression devices
to ground at the connector. Output signals 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 out-
puts 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 protec-
tion 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 1µA 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 23 cm. (9.1
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 23 cm. (9.1 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.

1. Review the locations where the Reader products need in-
tegrated. 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 t he radio and antennas w ith c abling are easily ac -
cessible for 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.
5. Do not transmit simultaneously with multiple antennas.

The following illustrations are a couple of examples for Reader
installations.
EXAMPLE 1: Shipping Dock Door, showing two antennas at each
shipping door. Two antennas in a crossing pattern
provide angular diversity to improve read capability
when tag orientation is unknown.
WARNING: While the device is on, the operator’s body and
parts of the body such as eyes, hands, or head,
must be 23 cm. (9.1 inches) or farther from the
cover of the antenna assembly.

provide angular diversity to improve read capability
when tag orientation is unknown.
The frames for these stations are PVC tubing with RF reflec-
tive Mylar liner X2. Ensure that an 9.1 inch (23 cm) distance
from the antenna assembly is maintained to limit people’s ex-
posure 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 23 cm. (9.1 inches) or farther from the
cover of the antenna assembly.

Connecting the Antenna to the Reader
1. Connect antenna cable to a port.
2. Connect a reverse-sex SMA terminator (Intermec p/n
345-004-001) to any port that does not have an antenna
attached.
"NOTE: Each port must have either an antenna or a termina-
tor connected.

Troubleshooting
Problem Solution
Doesn’t recognize tag 1. Check to ensure antenna is con-
nected 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 an-
tenna.
5. Access the Intermec web site
http://www.intermec.com or
http://NorBBS.Norand.com to down-
load and run the diagnostic test util-
ity 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 Inter-
mec Technical Support and give them the error codes you ob-
serve. They will step you through further diagnostic trouble-
shooting.

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 six tags per second. Tags located
too far away or in poor locations with respect to interfering
objects provides poor results. The Reader gets very warm
during continued use. In high ambient temperature (or high
temperature within host computer) conditions, the reader could
overheat.
