See the picture above: The Reader has a 4-row by 16-characterdisplay that is used to display tag data including, tag ID, temperature and pressure. Menus
Goodyear Portable Tire Reader – User Instructions 2GOODYEAR CONFIDENTIAL INFORMATION7376 07/13/01used for setting Reader options are also shown on the Reader display. The keypad is usedto select modes of operation (e.g. set date and time, choose display options, etc.).5. Read Modes. The Reader has three read modes: 1) READ AND RECORD, 2) READ ONLY,and 3) ADD AIR PRESSURE.• READ AND RECORD: In this mode, whenever the Trigger is pressed, the Reader driverfield is turned on briefly. The Reader attempts to read any tag in the read field during thistime. When a tag is read the ID number, temperature and pressure are displayed. Dataincluding the time, date, tag ID, temperature and pressure are stored in a data file.• READ AND RECORD WITH PRESSURE DATA ENTRY: This mode is the same as theREAD AND RECORD MODE but includes the option to manually enter an air pressure(e.g. from a tire gauge) that will be stored in the data file with the other informationassociated with that tag read.• READ ONLY mode: This mode is the same as READ AND RECORD mode except nodata are stored in Reader memory.6. Display Light. The keypad contains a key which switches a display light on and off. It is notrecommended that tags be read with the light on.7. Data Storage. When the Reader is in either of the READ AND RECORD modes, the IDnumber, date, time, temperature, pressure, (and manually entered pressure if that mode isselected) for each valid read are stored in a sequential file in the Reader. The Readermemory can store up to 1000 reads. Subsequent reads will be displayed but will NOT beadded to the date file. Stored data must be downloaded or erased by connecting the Readerto a computer via the RS232 (comm) port. The amount of Reader memory available isdisplayed on the ‘Status’ screen.8. Time and Date. The Reader has an internal clock and battery that keep track of the time anddate even when the Reader battery is removed. The time and date should be checkedperiodically and reset if necessary (see procedure below).First Time Operation of the ReaderThe Readers come with the handle section removed. To attach the handle, align the connector inthe handle with the mating connector in the base of the Reader. Insert the handle until the handleand the base of the Reader touch. Tighten the two captive screws. A black plug is provided thatsnaps into the hole in the top of handle to cover the upper captive screw.Before using a Reader, insert a battery pack into the handle until it snaps into place. Note thatthe battery should be charged prior to first use.Battery UsageThe battery pack should provide several hundred tag-reads between charges. When the batteryrequires recharging, the Reader will emit a Low Battery Signal during the read process. Thissignal is a single tone for approximately one second. Tags can be read after the Low BatterySignal, but the battery pack should be replaced and recharged as soon as possible after it occurs.A fully discharged battery takes about one hour to recharge. The battery pack is only partiallydischarged when the Low Battery Signal occurs, and recharging should take about one-half hour.The battery charger provides an indication when the battery is fully charged (see battery chargerdocumentation).Basic OperationTo turn on the Reader, push the Read push-button (Trigger) on the handle once. After theReader is turned on, pushing the Read push-button will cause the Reader to interrogate tags. Ifthe battery has been replaced since the Reader was last used, select the proper operating modefrom the keypad before reading tags (see Reader Setup section below.)
Goodyear Portable Tire Reader – User Instructions 3GOODYEAR CONFIDENTIAL INFORMATION7376 07/13/01To read the tire, the antenna section should be placed directly over the “Wingfoot”, and in contactwith the tire tread.Main Menu (SELECT MODE MENU) OptionsTo turn on the Reader pull the Trigger (on the handle) once. If the battery has been removedsince the last use the Reader will turn on displaying the Main Menu (if the display is all darksquares, the contrast is incorrectly set, see the section below on adjusting the display contrast).The title of the main menu is "SELECT MODE". All of the features and modes of the Readercan be reached from the SELECT MODE Menu by pressing the appropriate key andfollowing the displayed instructions. If the battery has not been removed, the Reader turns onwith the same display as when the Reader automatically turned off. The SELECT MODE menucan be reached from any Reader display by pressing the MODE key once or twice asrequired. The SELECT MODE appears as:SELECT MODE1 = READ & RECORD2 = READ ONLY3 = ADD AIR PRESSThe SELECT MODE menu has two screens. The second screen, shown below, is reached bypressing the MODE key one time when the Reader is displaying the first SELECT MODE menu.4 = NOT AVAILABLE5 = SETUP6 = STATUSNote that selection 4 is reserved for future use.Setting the Time and Date:To review the time and date setting, reach the SELECT MODE menu and select any Read Mode(i.e. 1, 2 or 3). The current time and date will be seen at the bottom of the display (it isrecommended that the time and date be checked whenever the Reader has not been used forseveral days). If the time or date are incorrect and need to be set, perform the following steps:To set the Time:1. Press the Mode key until the display shows the following:4 = NOT AVAILABLE5 = SETUP6 = STATUS2. From this display, press 5, to get this display: SET UP OPTIONS1 = TIME 4 = PRESS2 = DATE 5 = ODOM3 = TEMP 6 = TREAD3. From this display, press 1 and follow the instructions on the display to enter the correct time.Note that all 4 digits must be entered for the time followed by a 1 or 2 for AM or PM; theENTER key must be then be pressed to store the entry.
Goodyear Portable Tire Reader – User Instructions 4GOODYEAR CONFIDENTIAL INFORMATION7376 07/13/01To set the Date:After the time is entered and the ENTER key is pressed, the display will once again become:SET UP OPTIONS1 = TIME 4 = PRESS2 = DATE 5 = ODOM3 = TEMP 6 = TREADPress 2 to set the current Date. As before, follow the instructions on the display and pressENTER after the last numeric entry.To set the Temperature Units:The Reader can be set to display temperature in either Fahrenheit or Centigrade. The defaultsetting is degrees Centigrade. Temperature units can be set by pressing the Mode key untilSetup can be selected. Press Setup (5) and Temp (3) and select the desired temperature unitsby pressing the appropriate number key. Note that this setting only affects the temperature unitsdisplayed. Data are always stored in degrees Centigrade.Calibration Type:The Calibration type will default to the Standard setting. This setting should NOT bechanged except for use under specific circumstances.The Reader was designed to allow Goodyear to evaluate different calibration methods. Thecalibration for the “G3 – A” reader is Type T3.If somehow the calibration setting gets changed, or the reader is giving bad data for every tire,you can check the calibration type to make sure it is Type T3To review or change the Reader Tag Type setting:1. Push the MODE key twice to display the following menu:4 = NOT AVAILABLE5 = SETUP6 = STATUS2. From this display, press 5, then press ENTER to display the SET UP OPTIONS:SET UP OPTIONS7 = DISP 0 = IDONLY8 = CAL9 = AMBIENT3.

Press 3 to set the calibration type to T.Display Type – Normal vs. CountsThe Display Type default is ‘Normal’ (i.e. pressure and temperature). Do NOT adjust theDisplay Type unless required to do so for a specific application.For normal use, the “Normal” setting will display all the data that is needed:TIRE ID 00C10865PRESSURE =100PSISWITCH = 1TEMP. 73 F TFor test purposes, or to “debug” the reader, it is useful to know the raw pressure and temperaturedata transmitted by the tag prior to the Reader converting this data into pressure or temperatureunits. This raw data is called "counts". If necessary, the Reader can be setup so that it displayscounts as well as the converted pressure and temperature values.To set the Display Type to Counts:1. Push the MODE key twice to get the following display:4 = NOT AVAILABLE5 = SETUP6 = STATUS2. From this display, press 5, then press ENTER to show the following display:SET UP OPTIONS7 = DISP 0 = IDONLY8 = CAL9 = AMBIENT3. Press 7 to show the following display:SET DISP TYPEDISP IS NORMAL (This line shows the current Reader setting)1 = NORMAL2 = COUNTSPressing 2 will set the Reader to display count information. An example of a display after readinga tag in this mode is:TIRE ID 00C1086525 C 2350 235098 PSI 450 450CAL TYPE IS T3In the above example, 2350 is the temperature count and 450 is the pressure count. The tagtransmits all of its data twice, yielding the two values. The Reader does not store the countvalues in memory. Therefore, any record of the tag counts must be manually logged.
Goodyear Portable Tire Reader – User Instructions 6GOODYEAR CONFIDENTIAL INFORMATION7376 07/13/01To set the Display Type to Normal:Follow the steps above except in step 3, press 1 to select the normal display mode. An exampleof a display after reading tags in the Normal mode is shown below:TIRE ID 00C10865PRESSURE <=100PSISWITCH = 1TEMP. 73 F TSetting Ambient Pressure and Temperature CalibrationYou SHOULD NOT have to adjust the ambient pressure and temperature settings (exceptafter new software has been programmed into the Reader).The Reader contains an internal barometric pressure sensor and a temperature sensor. Thebarometric sensor enables the Reader to subtract the ambient air pressure from the tag reading,which is an absolute pressure reading. This enables the Reader to display the gauge pressure ofthe tire for any altitude or ambient air pressure, which is typical for tire air pressure gauges. Thetemperature sensor serves the purpose of adjusting the contrast of the Reader display, whichchanges with temperature. The ambient barometric pressure and temperature are set at PhaseIV and will only need to be reentered if the software in the Reader is changed. If entry of thisinformation is necessary, perform the following steps:If a barometer is available it may be used to determine the correct atmospheric pressure. The unitof measurement for most barometers is inches of mercury. For entry into the Reader, these unitsmust be converted to PSI by the following formula: PSI = inches of Hg x .4912. If a barometer isnot available, 14.5 PSI may be entered (at sea level). The temperature entry is not critical; entryof 25° C (approximate room temperature) is adequate for most purposes.To set the Ambient Pressure and Temperature:1. Turn the Reader on by pushing the Read-Trigger on the handle.2. Push the MODE key twice to get the following display:4 = NOT AVAILABLE5 = SETUP6 = STATUS3. From this display, press 5 then press ENTER to get the following display:SET UP OPTIONS7 = DISP8 = CAL9 = AMBIENT4. From this display, press 9, to get the following:AMBIENTPRESS = 12.1 PSITEMP = 25.8 CP = . T = .5. To enter the correct barometric pressure in PSI; enter three digits (two digits plus onedecimal). Note that he Reader will automatically enter the decimal point. After the barometric
Goodyear Portable Tire Reader – User Instructions 7GOODYEAR CONFIDENTIAL INFORMATION7376 07/13/01pressure is entered the Reader will automatically move the prompt to the temperature field.Enter the current ambient temperature in degrees Centigrade (including one decimal). PressEnter to store the ambient pressure and temperature data. Press Exit to abort data entry andto leave the current settings unchanged.Reading TagsBefore reading tags one of the three reading modes must be selected. This is done from the firstscreen of the SELECT MODE menu shown below.SELECT MODE1 = READ & RECORD2 = READ ONLY3 = ADD AIR PRESSFrom the above menu select the desired reading mode by pressing the associated numberkey.When a Read Mode is selected, the mode title, time and date are displayed. The Readerstays in a selected mode (even after automatic shut down) until a different mode is selected oruntil the battery is changed.Once the mode is selected, every press of the Trigger causes the Reader to activate the driverfield for 0.2 seconds. The Reader attempts to read any tag in the field during this time. TheReader emits a single beep when the Trigger is pressed immediately followed by a double beep ifa valid read is achieved. The Reader displays the ID number if a valid read occurs, otherwise itdisplays "NO VALID READ". The display stays on for two minutes after any read is attempted atwhich time the Reader automatically turns itself off. After any automatic shut down the Readercan be turned on by pressing the Trigger once at which time the Reader will turn on in the mode itwas in when it shut down. If this is the desired mode, tag reading can be reactivated by pressingthe Trigger a second time.Status DisplayTo view the STATUS information, press the MODE key as required to display the second screenof the SELECT MODE menu:4 = NOT AVAILABLE5 = SETUP6 = STATUSAt this menu, press key 6. When selected, the STATUS feature displays the electronic serialnumber of the Reader, the Software Revision, the number of files stored and the percent of theReader memory which has been filled by the stored files.Adjusting the Display ContrastThe display contrast can be adjusted using the DELETE (←←←←) and the EXIT (→→→→) keys.Reader Driver and Receiver Test ProcedureThe Reader Drive and Receiver circuitry can be tested using the included poker chip tag and byfollowing the test procedure below. Note that the poker chip tag supplied is a working unit thatwas rejected for failing one of the calibration criteria. While the pressure displayed by the Readermay be incorrect, the test procedure uses relative temperature values and will be unaffected bythe actual values. The procedure listed below assumes the Reader is set to a mode that willdisplay temperature in Fahrenheit. See the procedures below:
Goodyear Portable Tire Reader – User Instructions 8GOODYEAR CONFIDENTIAL INFORMATION7376 07/13/01To Test Reader Performance:1. Turn On the Reader and select the Read Only mode.2. Place the poker chip tag in the center of the antenna paddle area.3. Trigger the Reader 10 times and note the temperature displayed. The Reader should read atleast eight times out of ten.4. Hold or support the poker chip tag 2” above the center of the antenna paddle area (do notuse metal objects to support the tag).5. Trigger the Reader 10 times and note the temperature displayed. The Reader should read atleast eight times out of ten and the displayed temperature should be within 3° F of thetemperature displayed in step 3.If the Reader read eight out of ten times in both positions, the receiver is working properly.
