Ventilation RequirementsThe RealScan 7875 is designed to operate without an exhaust fan in the checkstand;however, there must be adequate convection airflow. The ambient temperature insidethe checkstand cannot be higher than 40° C (104° F). Also, the ambient temperatureinside the checkstand cannot be higher than 7° C (12.6° F) above the ambienttemperature outside the checkstand. For example, if the ambient temperature outsidethe checkstand is 24.4° C (76° F), the ambient temperature inside the checkstand cannotbe greater than 31.4° C (88.6° F). If the checkstand contains other heat producingequipment, you may need to use forced air to keep the temperature within the specifiedrange. However, air coming into or leaving the checkstand MUST NOT enter or exitpast the RealScan 7875.

Step 3 – Install RealScan 7875 inCheckstand

Set the Communications Protocol SwitchNote: RealScan 7875 Super ASIC models do not have Communications ProtocolSwitches. Continue on to the next task.

Before setting the RealScan 7875 into the cutout in the checkstand, verify that theCommunications Protocol Switch is properly set. Single cable units have one switch,dual cable units have two. The switches are located on the Interface Board and you canaccess them through holes in the side of the unit. For RS-232 communications, bothswitches must be toward the front (operator side) of the unit. For all othercommunication protocols, both switches must be toward the back (customer side) of theunit.

Step 4 – Calibrate the Scale

If you are not installing a RealScan 7875-2000/8000, do not perform this step but godirectly to Step 5 – Set the Program Parameters.

Note: The Bizerba computing scale, used in a RealScan 7875-4000, is calibrated at thefactory and cannot be calibrated in the field. However, you can reset the scale byturning off the power, then turning it back on with no weight on the Top Plate. If youare installing a RealScan 7875-4000 with a Bizerba scale do not attempt to calibrate thescale, but continue to Step 5 – Check the Scanner Operation.

Note: You MUST calibrate the scale when you install a RealScan 7875-2000/8000. To bein compliance with governmental weights and measures regulations, you must becertified to calibrate the scale.

Note: Calibration information is NOT sent to the host terminal. If your RealScan 7875does not have voice enabled or does not have a remote display, you must use a FieldService Calibration Display.

Note: Be sure the Interface Cable between the RealScan 7875 and the host terminal isdisconnected during scale calibration. Some host terminals can cause interference thatcan invalidate the scale calibration.

You can calibrate the scale after power has been supplied for 30 minutes if the ambienttemperature has been 20° C (68° F) for at least 24 hours. If this condition is not met, thenthe scale must be on for at least 6 hours before you can calibrate it. Also, you must use acertified weight set to calibrate and certify the scale.

The RealScan 7875 maintains an audit trail of scale calibration and programmingactivity. The audit trail records the number of times the scale has been calibrated. Youcan display the audit trail count on a Remote 7825 or Field Service Calibration Displayby pressing the Scale Zero Button on the Operator Display Panel. The display alternatesbetween Cal xxx and PAr xxx.

Exercise the ScaleYou must exercise the scale before performing a calibration. Add and remove weight toyour scale in the order given in the following chart. This is a building procedure inwhich you start with no weight (0) and sequentially add and remove weight to obtainthe values shown in the chart. Go through this procedure four times.

Step 5 – Set Program Parameters

Now you need to make any necessary programming changes to the RealScan 7875. TheRealScan 7875 does not have an On/Off switch. Use the circuit breaker switch in thecheckstand that supplies power to the unit as the On/Off switch.

Setting the Program ParametersCaution: Some host terminals can corrupt the RealScan 7875 program if they arerunning and are connected to the RealScan 7875 while you are making programchanges. Either turn off the host terminal or disconnect the interface cable beforescanning any programming tags.

To make changes to the program parameters, enter information from the ProgrammingWorksheets located toward the back of this book. The Programming Worksheetsidentify all the available program parameters. Each worksheet relates to a specificprogramming mode. Most programming options have defaults, identified by a heavybox, which are determined at the factory. Scanning the Default tag as the first tag afterapplying power to the unit sets the parameters to these values.

Changing the RealScan 7875 program is accomplished by scanning the proper sequenceof programming tags. Following are three major steps for making program changes.

1. Enter the Base Programming State by scanning the Programming Mode tag; mustbe first tag scanned after applying power.

2. Select a Programming Worksheet and enter its parameter data by scanning theappropriate Hex tags.

3. Save the program by scanning the Save and Reset tag.

Note: In most cases the factory determined defaults are the correct parameter setting.However, if you do need to make changes, it is recommended that you first set allparameters to default values then make any necessary changes to the appropriateparameters.

Reduced Space SymbologyReduced Space Symbology (RSS) permits more data to be recorded in a smaller physicalspace. This is accomplished by encoding the data in large symbol characters rather thanencoding each data character separately. Also, no quiet zone is required around thesymbols. The RealScan 7875 with RSS can read four types of RSS bar codes.

RSS-14

RSS-14 is a linear symbology that encodes 14 UCC/EAN digits. This structure providesfour segments that can be scanned and decoded separately, then reconstructed. Thetotal symbol contains 96 modules combined into 4 elements (bars and spaces).

Sensormatic Deactivation SystemNote: Refer to the Sensormatic ScanMax™ Pro Controller documentation forinformation about setting up the controller.

When the RealScan 7875 is first turned on, all the Sensormatic parameters should be attheir default settings. Use the following procedure to program the system and make itoperational.

1. Scan the Restore Sensormatic Parameters tag. The security tag deactivationfunction must be disabled (default).• Security tag deactivation function is enabled.• Security tag deactivated tone is enabled.• Security tag deactivated tone is set to a single long tone.• Security tag detected tone is enabled.• All other necessary parameters in the RealScan 7875 are set to default values.• The RealScan 7875 checks the parameters set in the Sensormatic ScanMax™ Pro

Controller. If the parameters are set to match the RealScan 7875 defaults, theRealScan 7875 generates the voice message EAS Online, otherwise the RealScan7875 generates the voice message EAS Online Mode One.

2. Two options are available if the EAS Online Mode One message is given:download the RealScan 7875 parameter defaults to the ScanMax™ Pro Controller ormake necessary changes directly to the ScanMax™ Pro Controller.

Download 7875 Parameters to ScanMax™ Pro Controller

To use the RealScan 7875 parameter defaults, scan the Restore Sensormatic Parameterstag. This downloads the default parameters to the ScanMax™ Pro Controller.

Set ScanMax™ Pro Controller Parameters at the Controller

If the RealScan 7875 default parameters are not exactly what are needed, you can makechanges directly to the ScanMax™ Pro Controller. Refer to the Sensormatic ScanMax™Pro Controller documentation.

1. Make all the necessary changes to the ScanMax™ Pro Controller according to theSensormatic documentation.

2. Scan the Reset tag and listen for Change in Parameters.3. Scan the Save Sensormatic Parameters tag. This sets the RealScan 7875 parameter

defaults to those set in the ScanMax™ Pro Controller.

Should the ScanMax™ Pro Controller lose its settings or be replaced, scan theRestore Sensormatic Parameters tag and restore the parameters at the controller.

Note: Scanning the Save Sensormatic Parameters tag enables soft defaults in theRealScan 7875 and sets them to the ScanMax™ Pro Controller values.

Operating the Scanner

The RealScan 7875 is a fixed position device that is installed in a checkout counter. It isnot handled or moved by the operator during operation. The RealScan 7875 ismaintained and serviced by trained service personnel only. The operator has no accessto any laser module components.

The RealScan 7875 does not have a power switch. However, you turn it on and off byusing the circuit breaker switch, located in the checkstand, that supplies power to theunit. Be sure this switch is in the On position.

The Status Indicator on the Operator Display Panel is Red when the RealScan 7875 isready. The correct way to scan is to slide an item from the checkstand, across thescanner, and back onto the checkstand. With a good scan, the Status Indicator FlashesGreen, then turns Red. Nothing happens if the bar code is not read.

Operating the Scale

The RealScan 7875 typically takes from 1.0 to 2.0 seconds to weigh an item, dependingon the item’s weight. The heavier the item, the longer it takes. Before weighing an item,make sure the scale display is displaying all zeros. If not, press the Scale Zero Button.

Note: The item you are weighing should be placed in the center of the Top Plate. Makesure the item does not overhang onto the checkstand; whatever is weighed must fit fullyon the Top Plate. If the RealScan 7875 includes the Produce Guard, larger items may restagainst it.

When the scale weighs an item, the Status Indicator flashes Green and a good weightone is sounded. Nothing happens if the scale cannot weigh an item.

Operating the SensormaticDeactivation System

Normal OperationThe operating procedures can vary according to the parameter settings. The followingprocedure assumes the Sensormatic parameters are set to the following values.

• Security tag deactivation function is enabled.• Security tag deactivated tone is enabled.• Security tag deactivated tone is set to a single long tone.• Security tag detected tone is enabled.

Following procedure assumes the RealScan 7875 and the Sensormatic ScanMax™ ProController are turned on and functioning properly.

1. Pass an item across the scanner.2. As the bar code goes through the scan zone, the RealScan 7875 reads it and sounds a

Good Read tone.3. As the security tag goes through the Sensormatic deactivation zone, the Sensormatic

system deactivates the security tag and a Security Tag Deactivated tone sounds.This normally happens fast enough that the Security Tag Detected Tone does notsound.

Note: The security tag must be detected by the Sensormatic system with twoseconds after the RealScan 7875 reads the bar code. If more than two seconds elapse,the security tag is not deactivated even when it does come into the deactivationzone. In this case, the Security Tag Detected Tone sounds while the tag is in thedeactivation zone. The sound is similar to a Geiger counter. When this conditionoccurs, the security tag must be deactivated manually.

Manual DeactivationIf for some reason the security tag is not deactivated in the normal manner, it can bedeactivated manually. This normally occurs when too much time elapses after theRealScan 7875 reads the barcode. There are two ways to initiate a manual security tagdeactivation.

1. Press the Volume button on the RealScan 7875 or scan the Manual Deactivation tag.The RealScan 7875 laser light and spinner motor turn off, disabling the scanner.

2. Pass the security tag into the deactivation zone. The Security Tag Detected Tonesounds (similar to a Geiger counter) and the tag is deactivated. The RealScan 7875laser light and spinner motor turn on, enabling the scanner.

Cleaning the RealScan 7875

Keeping the scan windows clean helps keep the read rate exceptionally high. Duringnormal operation the scan windows get dirty, and if you permit the dirt to accumulate,performance degrades to the point where the scanner cannot read bar codes. The PleaseClean Window indicator flashes when the scan windows need cleaning. Use a soft clothmoistened with a common, non-abrasive, liquid window cleaner to clean the scanwindows. Be sure to spray the cleaner onto the cloth, not directly onto the RealScan 7875

Note: Scale problems can occur from debris collecting under the Top Plate. Be sure tokeep the plastic Subplate clean to prevent interference with the Top Plate whenweighing items. Debris can also collect behind and under the Produce Guard. Keep thisarea clean, which requires removing the Produce Guard.
