Both RS-232 and RS-422 standards are supported as ordered from the factory or service center. Table 1-1 RS-232 Connections Pin Number Definition 2 3 5 7 8 Serial Data from the Fixed Reader to the host Serial Data to the Fixed Reader from the host Ground CTS (Clear to Send) to the Fixed Reader from the host RTS (Request to Send) from the Fixed Reader to the host Table 1-2 RS-422 Connections Pin Number Definition 1 4 5 6 9 Serial Data Out + from the Fixed Reader to the host Serial Data Out -- from the Fixed Reader to the host Ground Serial Data In + to the Fixed Reader from the host Serial Data In -- to the Fixed Reader from the host The default baud rate is 115.2 kbps with 8 data bits, no parity and 1 stop bit. 3 ITRF24501 Reader Quick Start Guide 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 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 a CUI
# SD-130, (one source is Digi-Key #CP-1013-ND). Table 1-3 I/O Pin-outs Definition GPIO IN0 GPIO IN1 GPIO IN2 GPIO IN3 GPIO OUT0 GPIO OUT1 GPIO OUT2 GPIO OUT3 GROUND though individual 10 ohm resistors Pin Number 1 2 3 4 5 6 7 8 9, 10, 11, 12, 13 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 4 ITRF24501 Reader Quick Start Guide climb higher as the sink current increases. There is no protec-
tion on this. You need to ensure that their load wont require the reader to sink more than 50 mA. 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 1A 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. 5 ITRF24501 Reader Quick Start Guide 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 operators 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. 6 ITRF24501 Reader Quick Start Guide 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 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 the radio and antennas with cabling 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. 7 ITRF24501 Reader Quick Start Guide 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 reflec-
tive Mylar liner X2. Ensure that an eight inch (20 cm) distance from the antenna assembly is maintained to limit peoples ex-
posure to radiofrequency (RF) radiation. WARNING:
While the device is on, the operators 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. Conveyer Belt #1 Conveyer Belt #2 33 Max. distance to tag A singular antenna in a portal may be sufficient in applications where there is a known tag orientation 8 ITRF24501 Reader Quick Start Guide 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 anten-
na attached.
" NOTE:
Each port must have either an antenna or a termina-
tor connected. Antenna ports 4 3 2 1 SMA terminator Back panel Antenna cable 3. Connect the Reader to a power source using power supply p/n 351-066-001 and country dependent AC power cord. 4.

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. 11 ITRF24501 Reader Quick Start Guide 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 second. Tags located too far away or in poor locations, with respect to interfering objects, provides poor results.
