Scorpion I Reader Copyright 2001 RF Code, Inc. 11 IntroductionThe RF Code Scorpion I System is an RFID monitoring system designed to reporttags within defined reader operating ranges. The system utilizes “beacon” tagsthat periodically report their presence with an encoded radio transmission. TheScorpion I Reader is a dual channel radio receiver tuned to the Scorpion I Tagtransmission frequency.The Scorpion I includes a Client Bridge as the interface between the Scorpion IReader and an Ethernet network. The reader receives the message and decodesthe tag’s identity each time the tag transmits. The reader sends the tag identityinformation through the Client Bridge to the RF Code Concentrator LI softwareapplication for processing. The Client Bridge can be configured to operate as awired connection to the Ethernet 10/100 network, using an RJ-45 connector, orusing an IEEE 802.11b wireless connection to the host computer.2 PurposeThis manual provides instructions for the Scorpion I Reader setup and operation.The Scorpion I Reader has different modes of operation and optional functionsthat are user-selected, depending on the system’s operational requirements.3 ScopeThe instructions in this manual show how to configure the Scorpion I Reader forphysical options contained within the device itself. Operational Instructions for theScorpion I System using RF Code’s Concentrator LI software are found in theConcentrator LI User’s Guide; RF Code publication IS1007
Scorpion I IIIAR Reader2 Copyright 2001 RF Code, Inc.4 Scorpion I ReaderThe Scorpion I Reader contains the internal components of an RF Code Scorpion IReader and an Ethernet Client Bridge and is housed in a 12” x 8.5” x 2” painted,aluminum chassis with screw-on cover. The reader works with Scorpion I Tagsthat periodically transmit an encoded radio signal identity. The reader decodeseach tag’s signal and sends that information to the host processor, using theEthernet Client Bridge as a communication interface to the local area network(LAN).4.1 Scorpion I Reader Physical I/OFigure 1 Scorpion I Reader (Front View)Each Scorpion I Reader Antenna Post (A & B) supplies an RF signal to thetwo parallel radio receivers in the Scorpion I Reader. Reference Paragraph4.3, Page 7 for antenna positioning for optimum performance. The antennainput impedance is 50 ohms nominal.Charge Indicator is on while the reader is in operation. The light may or maynot be on while the power is applied, even when the reader’s power switch isoff.On- Ready Indicator light, when illuminated, indicates the Scorpion I Readerhas power applied through the external power connector and the power switchis on.Tag Activity Indicator light is used for two purposes: to show the status ofthe reader while in standby mode and to show tag detections while in activemode.Fast ChargeOn - ReadyTag ActivityChargeindicator Power onindicator Tag ActivityindicatorWireless EthernetAntennaScorpion IReader AntennaAB
Scorpion I Reader Copyright 2001 RF Code, Inc. 31. While in active mode, the light flashes at random indicating the readerhas read one or more tags each time it flashes. Because the readercan decode tags faster than the light can be turned on and off, a singleflash may indicate more than one tag being decoded. When theScorpion I Reader is using the auto-registration mode, the activity lightflashes may indicate auto-registration activity prior to reporting tag IDsto the network.2. While in standby mode, the reader’s Tag Activity light turns on and offat a distinctively cyclic rate that indicates the reader is in standby mode.The Wireless Ethernet Antenna is positioned on the outside of the Scorpion Ichassis while being plugged into the Client Bridge inside the chassis. Theantenna is on the end of a PCMCIA card that is plugged into the Client Bridgethrough a cutout in the Scorpion I enclosure.Figure 2 Scorpion I (Rear View)Ethernet Connector is an RJ-45 Ethernet jack to be used as the terminationpoint when this reader is part of a wired Ethernet LAN network. This readercan be connected to a standard 10 Mbps network or a 10/100 Mbps networkthat can switch speeds down to 10 Mbps.Chassis Ground Terminator is a screw terminal that can be used toelectrically ground the Scorpion I chassis. Normally this termination is notused because the reader is grounded through the third wire ground lead in thepower connector. The only time this Chassis Ground terminator should beused is if the ground through the power connection is not connected.Caution: Do not install this reader with both grounds connected. Ifboth grounds are connected, severe damage to the reader may resultduring a near proximity lightning strike.Chassis GroundTerminator PowerConnector Power On/OffSwitchEthernetConnectorlO10+10-24 VAC/DC 1ANetwork

The switch is on when itis in the 1 position.Power Transformer has a three-pin keyed connectorused to supply power from the power source to thereader. The power transformer supplied with theScorpion I provides the reader with 18 volts AC. Thepower transformer plugs into a standard 110 – 125VAC wall outlet. The cable’s active leads are labeled~ and ~, the Gnd lead is connected to the wall outletground. The “Open” terminal is not used in thisapplication. The factory- supplied cable is connectedto the transformer using wire colors shown below thetermination blocks. The factory supplied cable terminates in a circular 97Series screw connector at the Scorpion I Reader.If the reader is being supplied with DC power, the DC power is suppliedthrough the black and white wires (either polarity) with the blue wire connectedto earth ground.BlackWhiteBlueOpen ~ ~ Gnd

The PCB on the side of the enclosure extends the twoantenna posts through the side of the enclosure. The main PCB is theprocessor and data interface to the outside world. These two boards operateas one Scorpion I Reader through a right angle connector.The main PCB has a power switch (SW2) that must remain in the On position,all the time. The main PCB also has an eight-position Dipswitch (SW1) thatpermits the selection of specific functions and baud rates used by the reader.The SW1 Dipswitch factory setting is switches two and six on and all otherswitches off as shown in Figure 3. Each time the reader is turned on, it isrestored to the default settings which is determined by this switch. Most of thereader’s configuration controls are implemented by serial download34567281Scorpion IPower SupplyEthernetClientBridge3M6M11M22M6H3H45M12HPower SwitchSW2Function SelectSwitch SW1Watchdog TimeSelect P2

Instructions forthe Scorpion I Reader’s operation using RF Code’s Concentrator LI are foundin the Concentrator LI user’s guide; RF Code publication number 03801400-11.To implement a feature required in the Scorpion I’s operation, the reader issupplied with an empty battery holder. Batteries are not used in the Scorpion Iapplication. Do not install batteries in the battery holder.Caution: By installing batteries, the reader will lose a functionalfeature and could possibly create a physical hazard to the user.The Power Supply printed circuit board provides power to the Scorpion IReader and the Client Bridge inside the enclosure. The power supply PCBreceives its power from the external power connector and will operate with 10to 18 volts, either AC or DC input.The power supply PCB also provides a communication watchdog between theScorpion I Reader and the Client Bridge. The watchdog monitors thecommunication handshake lines between the two devices. If there is nocommunications activity from either the Client Bridge or the Scorpion I Readerfor the period of time selected by the P2 jumper, the watchdog power cycles(momentarily turns off the power) to both devices at the same time. Powercycling restarts both units in their default startup configuration, which permitsthem to resume normal communications.The inactivity watch time is set with a Jumper on P2 termination strip. Theinactivity watch time can be set as short as three minutes (3M), and as long astwelve hours (12H), with six intermediate steps between these extremes. Thewatchdog times are approximate and not intended for exact timing. Thefactory setting is three minutes and can be changed by removing the selectionjumper from the three-minute (3M) P2 terminals and placing it on the desiredP2 terminals. Note: do not operate the reader with the jumper removed; thewatchdog requires a valid jumper position to operate correctly.The Ethernet Client Bridge can be operated using the wireless 802.11bEthernet link or the wired RJ-45 connection. If wired Ethernet is to be used,remove the wireless PCMCIA card from the Client Bridge while the unit’spower is turned off. Connect the Ethernet access RJ-45 cable into the reader.
Scorpion I Reader Copyright 2001 RF Code, Inc. 7If wireless Ethernet is used, plug the wireless PCMCIA card into the ClientBridge while the unit’s power is turned off. Do not attempt to use the wired RJ-45 connection at the same time the wireless PCMCIA card is plugged in.4.3 Scorpion I Reader AntennasThe type of antennas used and thereader’s range setting determine theeffective read range. The normalreader range features are definedusing ¼ wave helical antennas. Theseantennas are appropriate for mostreader applications. Optional antennasthat offer diverse receiving properties are available for the Scorpion I Reader.Contact your Scorpion I Reader distributor for more information.The Scorpion I Reader has two receiver channelsthat can operate independently, or jointly, to providetag signal diversity reception. The reader canoperate with one antenna on either antenna post;the benefit of receiver diversity reception is obtained with both antennasattached.To achieve the best receiver diversity, it is desirable to have the antennaspositioned at different angles from the reader. Because the tagsmay be located at various places and orientations around thereader, the signal path to the reader may vary for each tag.Because the signal path is different for each tag, one antennamay see the signal while the other may not. Keep theantennas separated; having the antennas overlapped cancels theeffectiveness of each antenna. It may be necessary to experiment withantenna positions to achieve optimum coverage.

If the antennas are mounted on the reader, then these installationinstructions apply to the reader with the antennas installed on the reader.As a general rule, the higher the antenna is positioned above the ground orfloor, the better the reader’s detection range. Detached antennas with lowloss SMA coaxial extension cables connected to the reader may be used toseparate the reader from the antennas.To minimize RF interference, maintain a four to six foot separation betweenthe Scorpion I Reader antennas and potential RF radiators such ascomputers, monitors, printers and electronic office equipment. The local radioenvironment can limit the reader’s effective range. Grounded and reflectivemetallic structures around the reader’s antennas and/or tags affects thesystem’s performance.As a general rule, the reader’s antennas should be mounted as high asreasonably possible. However, mounting the antennas on the ceiling that isalso the floor of the story above may be detrimental because the antennas arelocated near a “grounded floor”. The difference is, the floor is now above thereader instead of below the reader. It may be necessary to experiment to findthe optimum position for placing the reader’s antennas.Figure 4 shows the chassis mounting tabs on the Scorpion I Reader. Thedimensions are in inches.
