When a bar code is scanned, additional information is sent to the hostcomputer along with the bar code data. This group of bar code data andadditional, user-defined data is called a message string. The selections in thissection are used to build the user-defined data into the message string.Prefix and Suffix characters are data characters that can be sent before andafter scanned data. You can specify if they should be sent with allsymbologies, or only with specific symbologies. The following illustrationshows the breakdown of a message string:

Prefix Scanned Data Suffix1-10alpha

numericcharacters

variablelength

1-10alpha

numericcharacters

It is not necessary to build a message string. The selections in this chapterare only used if you wish to alter the default settings. Default prefix = None.Default suffix = None.

A prefix or suffix may be added or cleared from one symbology or allsymbologies.

You can add any prefix or suffix from the ASCII chart (pg. 45 ), plus CodeI.D. and Aim I.D.

You can string together several entries for several symbologies at one time. Enter prefixes and suffixes in the order in which you want them to appear on

the output.

STEP 1. Scan the Add Prefix or Add Suffix symbol (pg. 44).STEP 2. Determine the 2 digit Hex value from the Symbology Chart (pg.

45) for the symbology to which you want to apply the prefix orsuffix.

STEP 3. Scan the 2 hex digits from the Programming Chart inside the backcover or scan 9, 9 for all symbologies.

STEP 4. Determine the hex value from the Decimal to Hex to ASCIIConversion Chart (pg. 45) for the prefix or suffix you wish to enter.

STEP 5. Scan the 2 digit hex value from the Programming Chart inside theback cover.

Repeat Steps 4 and 5 for every prefix or suffix character.

To add the Code I.D., scan 5, C, 8, 0.To add AIM I.D., scan 5, C, 8, 1.To add a backslash (\), scan 5, C, 5, C.

STEP 6. Scan Save to exit and save, or scan Discard to exit without saving.

Repeat Steps 16 to add a prefix or suffix for another symbology.

Example: Add a Suffix to a specific symbologyTo send a CR (carriage return) Suffix for UPC only:STEP 1. Scan Add Suffix.STEP 2. Determine the 2 digit hex value from the Symbology Chart (pg.

45) for UPC.STEP 3. Scan 6, 3 from the Programming Chart (inside back cover).STEP 4. Determine the hex value from the Decimal to Hex to ASCII

Conversion Chart (pg. 45) for the CR (carriage return).STEP 5. Scan 0, D from the Programming Chart (inside back cover).STEP 6. Scan Save, or scan Discard to exit without saving.

You can clear a single prefix or suffix, or clear all prefixes/suffixes for asymbology. When you Clear One Prefix (Suffix), the specific character youselect is deleted from the symbology you want. When you Clear All Prefixes(Suffixes), all the prefixes or suffixes for a symbology are deleted.STEP 1. Scan the Clear One Prefix or Clear One Suffix symbol.STEP 2. Determine the 2 digit Hex value from the Symbology Chart (pg.

45) for the symbology from which you want to clear the prefix orsuffix.

STEP 3. Scan the 2 digit hex value from the Programming Chart inside theback cover or scan 9, 9 for all symbologies.

Your change is automatically saved.

Some terminals drop information (characters) if data comes through too quickly.Intercharacter, interfunction, and intermessage delays slow the transmission ofdata, which increases data integrity.Each delay is composed of a 5 millisecond step. You can program up to 99steps (of 5 ms each).

This is a delay of up to 495 milliseconds (in multiples of 5) placed between thetransmission of each character of scanned data. You can program up to 99steps (of 5 ms each). Scan the Intercharacter Delay bar code below, then scanthe number of steps, and the SAVE bar code from the inside back cover.

The Data Format Editor selections are used to edit scanned data. Forexample, you can use the Data Format Editor to insert characters at certainpoints in bar code data as it is scanned.It is not necessary to use the Data Format Editor. A set of defaults for the dataformat is already programmed in the scanner. The selections in the followingpages are used only if you wish to alter the default settings. Default DataFormat setting = none.If you have changed data format settings, and wish to clear all formats andreturn to the defaults, scan the Default Data Format code.To Add a Data FormatSTEP 1. Scan the Enter Data Format symbol (pg. 54).STEP 2. Primary/Alternate Format

Determine if this will be your primary data format, or one of 3alternate formats. (Alternate formats allow you single shotcapability to scan one bar code using a different data format. Afterthe one bar code has been read, the scanner reverts to the primarydata format. See page 56.) If you are programming the primaryformat, scan 0. If you are programming an alternate format, scan 1,2, or 3, depending on the alternate format you are programming.

STEP 3. Terminal TypeRefer to the Supported Terminals Chart (page 23) and locate theTerminal ID number for your PC. Scan three numeric bar codes onthe inside back cover to program the scanner for your terminal ID(you must enter 3 digits). For example, scan 0 0 3 for an AT wedge.

STEP 4. Code I.D.On pg. 45, find the symbology to which you want to apply the dataformat. Locate the Hex value for that symbology and scan the 2 digithex value from the Programming Chart.

STEP 5. LengthSpecify what length (up to 9999 characters) of data will be acceptablefor this symbology. Scan the four digit data length from theProgramming Chart. (Note: 50 characters is entered as 0050. 9999is a universal number, indicating all lengths.)

STEP 6. Editor CommandsRefer to the Format Editor Commands Chart (page 52). Scan thesymbols that represent the command you want to enter. 94alphanumeric characters may be entered for each symbology dataformat.

STEP 7. Scan Save to save your entries.

Alternate formats allow you single shot capability to scan one bar code usinga different data format than your primary format. When data formats areprogrammed (see page 51), you must input whether you are programmingthe primary format, or an alternate format numbered 1, 2, or 3.An alternate format is initiated by scanning one of the 3 alternate format barcodes below. The scanner will scan the next bar code, formatting the data withthe selected alternate format, then revert immediately to the primary format.

By switching interface cables, the 7837 scanner can communicate with aportable data terminal (secondary interface), in addition to the host terminal(primary interface).The secondary interface can be programmed at any time.

In Wand Emulation mode, the scanner decodes the bar code then sends datain the same format as a wand scanner. The Code 39 Format converts allsymbologies to Code 39. The Same Code Format transmits UPC, EAN, Code128 and Interleaved 2 of 5 without any changes, but converts all othersymbologies to Code 39. These codes set the transmission rate to 25 inchesper second and the output polarity to black, high. Default = Code 39 Format.

* Wand EmulationCode 39 Format

All communication parameters between the scanner and terminal must matchfor correct data transfer through the serial port using RS-232 protocol.RS-232 programmable selections are used by both the primary and secondaryinterfaces. Changing an RS-232 parameter (e.g., baud rate or parity), while inprimary or secondary mode will affect both interfaces.

The cloning procedure reprograms the software in the destination scannersmemory with software from the source scanner. Before using this procedure,determine which scanner will be the source (the scanner containing the desiredsoftware). The 7837 supports cloning and can act as the source device. Thesoftware in the destination scanner will be updated from the source scanner.The destination scanner device must be the same model as the source.

1. Use the cloning cable (4220455901) to connect the two scannersfor cloning.

2. Connect the destination scanner to one of the 10 pin modularconnectors on the cloning cable.

3. Connect the source scanner (containing the new or updatedsoftware) to the remaining 10 pin modular connector on the cloningcable.

4. Connect the power supply to the 4 pin miniDIN connector locatedon the cloning cable or the scanner cable.

5. Make sure both units are on, and then scan the Clone Destinationbar code with the destination scanner.

Clone Destination Bar Code6. Scan the Clone Source bar code below with the source scanner.

The scanners Good Read LED begins blinking periodicallyindicating cloning is in process.

Clone Source Bar Code7. When cloning is complete, the destination scanner will double beep.

This procedure takes approximately two minutes.8. Disconnect the destination scanner from the cloning cable.9. To clone another scanner, repeat steps 1 through 8.Caution: DO NOT scan the source bar code unless you are

going to clone a scanner. If you mistakenly scan thisbar code, reset the scanner by turning the power offand back on to regain normal operation.
