Introduction
Your bar code scanner has been programmed at the factory and should be ready to operate.
This document contains a verification sequence that allows you to determine whether your
scanner is programmed correctly and a programming sequence to follow if it is not
programmed correctly.
Setting Up the Scanner
1Turn off power to the Profit Point POS terminal.
2Unplug the AC power to the POS distribution box power supply.
3Remove the scanner power supply from the shipping box and discard per local practice.
4Open the MCA cover, make the following changes, then close the cover.
• Remove jumper/shunt from JP2 and discard (see Before in Figure 1).
• Move jumper/shunt from JP1 pins 2 and 3 (see Before in Figure 1) to JP1 pins 1 and 2 (see
After in Figure 1).
• If contained in shipping box, place power supply connector cover on power supply
connector on MCA (see After in Figure 1).
CAUTION
Be aware of the following:
• When an IEE®customer display is used, the scanner will be operating at the 9600 baud rate.
•When an Ultimate Technology®customer display is used, the scanner will be operatingat the
1200 baud rate.
•For Datalogic DLL2020 scanners, refer to MDE-4389 Setting Up Datalogic DLL2020 Bar
Code Scanner Used on Profit Point Terminal.
CAUTION
Before proceeding, make sure the Metrologic®Connector Adapter (MCA) is not connected to the
scanner, communication cable, or host.

5Insert the phone jack end of the scanner cable into the phone jack connector on the MCA
(Figure 1).
6Use the cable supplied with the scanner to connect the DB9 connector on the MCA (Figure 1)
to the SCANNER port on the POS distribution box.
7Plug in the POS distribution box power supply.
8Turn on the Profit Point POS terminal.
When you turn on the power to the Profit Point POS terminal, follow the instructions on the
screen. The Profit Point terminal will then initialize and begin POS operations.
Performing Verification Sequence
While in Point-of-Sale operations, scan an item. The scanner should beep when the item is
scanned.
•If the correct item description appears on the screen, the scanner is programmed correctly.
•If the message “# not on file”appears and the number shown on the screen matches the
number under the scanned bar code, the scanner is functioning correctly, but the bar code
cannot be identified. The display may not show the first or the last digit printed on the
item. Press CLEAR MENU to cancel the item entry.
•If the screen does nothing or displays”Data Error on Scanner Port”or “Item Entry Error,”
repeat the scan. If the same message displays, the scanner may be programmed
incorrectly. Proceed with “Programming Sequence”on page 3.
Note: The first time the scanner is turned on, the first scan may produce the error message
“Data Error on Scanner Port”even if the scanner is programmed correctly.

1Scan the bar code in Figure 10.
2Scan the bar codes one at a time and in the order given in the following table.
Note: When scanning the bar codes in Figure 2 through Figure 9, it may help to rotate them.
Each bar code has a page number in a note under it that corresponds to the hard copy page in
MLPN 2186 Metrologic®ScanSelect®Scanner Programming Guide included with the scanner.
If the bar code can not be read from Figure 2 through Figure 10, use the programming guide.
Note: A PDF version of MLPN 2186 Metrologic ScanSelect®Scanner Programming Guide is
available at the following URL.
ftp://ftp.metrologic.com/pub/download/productmanuals/00-02186.pdf
3Exit program mode by scanning in the bar code in Figure 10.
4The scanner should now be properly programmed. Repeat the “Performing Verification
Sequence”on page 2 to ensure proper programming.
Note: If after following all these instructions, the scanner still does not work, it may be
connected incorrectlyor the Profit Point POS terminal may notbe configured correctly.
Repeat “Setting Up the Scanner”on page 1. See the Hardware Configuration section in
