Introduction
The MS700iSeries Scanners are high throughput projection scanners that
incorporate the latest in VLD (Visible Laser Diode) ASIC/VLSI and surface
mount technologies. Each scanner consumes only 8 watts of power and can
directly connect to many host systems that can support a scanning device. One
thoughtful feature is a “sleep mode” that turns the laser and motor off when not
in use. Other features include easy-to-see LED indicators that can be viewed
from the top or front and a volume control card that can be scanned to control
volume levels. There are two programming methods: through the
ScanSelect™ programming guide or through ScanSet™ (an IBM PC
compatible software program.)
With a scan speed of 2,000 lines per second, these scanners aggressively scan
poorly printed bar codes and read torn and bent UPC, EAN and JAN bar
codes immediately on the first pass at any roll angle. For close scanning, the
MS700iand MS715i’s depth of field of 0.0mm - 178mm (0" - 7") is ideal. To
accommodate applications where scanning items farther away from the scan
window is preferred, the MS720i’s depth of field of 178mm - 381mm (7" -
15") is ideal.

Scanner Connections to the Host
To maintain compliance with applicable standards, all circuits connected to the
scanner must meet the requirements for SELV (Safety Extra Low Voltage)
according to EN 60950. To avoid potential problems, do not power up the
scanner until the communication cable is secured to the host.
1. Turn off the host system.
2. Connect the 25-pin D-type connector on the scanner’s head cable to the
communication cable. Connect the other end of the communication
cable to the host device. (If the scanner will not receive power from a
transformer, skip to Step 5.)
3. If the scanner will receive power from an external power source, check
the AC input requirements of the transformer to make sure the voltage
matches the AC outlet. (A socket-outlet can be installed near the
equipment so it will be easily accessible.)
4. Plug the transformer into the side of the female D-type connector
located on the communication cable. Plug the transformer into the AC
outlet to supply power to the scanner.
5. Power up the host system.
Note: When the scanner first receives power, the LEDs will flash and
then the scanner will beep once. After the scanner performs this
startup sequence, the green LED will remain on for a specified
time indicating that the laser is on.

Configuration of the Scanner to the Host System
The scanner is shipped from the factory programmed to a set of default
conditions. These default conditions are in the Default Settings section of this
guide pages 36-41 and in the ScanSelect™ Scanner Programming Guide. The
default settings in the ScanSelect guide have an asterisk that appears before
the brief definition next to the bar code.
For the scanner to properly communicate with the host system, it needs to be
programmed to meet the specific scanning needs. Since each host system is
unique, configure the scanner to match the host system requirements.
Configure the scanner by entering program mode and scanning the appropriate
bar codes that appear in the ScanSelect Scanner Programming Guide. (When
using ScanSet™, refer to the ScanSet documentation for information on how
to configure the scanner.)
1. Connect the scanner to the host system (Refer to the Scanner
Connections to the Host section in this guide).
2. Enter program mode by scanning the ENTER/EXIT program mode bar
code as the first bar code after a power up cycle. (The unit will beep
three times)
3. Scan the appropriate bar code(s) that appear in the ScanSelect Scanner
Programming Guide. (Reveal only one bar code to the scanner each
time. With your hand, cover the bar code that is not to be scanned.)
4. Exit program mode by scanning the ENTER/EXIT program mode bar
code again. (The new options will be saved and the scanner is ready for
normal operation.)
Note: Non-RS-232 interfaces chosen in Section B of the ScanSelect
Programming Guide do not match the default settings loaded when
the same interface is selected with ScanSet.
5
CLONING
Cloning Feature
To program several scanners with the same settings, use the Cloning feature.
This is done by connecting the cloning cable (MLPN: #51544) between two
scanners.
1. Turn off both scanners.
2. Connect the cloning cable between the two scanners.
3. Turn both scanners on by plugging in the transformers.
4. Once each scanner is ready, scan the cloning bar code with the scanner
that has the settings that need to be transferred to the other scanner.

Version 11 IBM 46XX Scanner
Output Format: IBM RS-485 serial input/output for the 4680 and 4690
(46XX) point-of-sale terminals
The Version 11 46XX interface can be used in several different ways. Both the
46XX terminal and the scanner must be configured to match each other.
Warning:Power to the scanner and 46XX terminal should be turned off
before making physical connection.
The 4680 and 4690 series terminals have different types of physical ports for
connecting bar code scanners. Scanner ports include Port 5B, Port 17, and
Port 9? (? = A, B, C, or E). A Port 9 type connector is present on all versions
of the 46XX families of terminals. That is one reason it is the normal point of
connection for Metrologic scanners. Another reason is that there is enough 12
volt power available to operate many Metrologic scanners. If the terminal
configuration requires use of a different physical port for connecting bar code
scanners, contact Metrologic to get particular adaptor cable information.
No matter what port is in use for the physical connection, all devices use a
common communications bus inside the 46XX terminal. Each device uses a
different address when it must communicate. The terminal must be configured
to look for a device at a logical address.
The IBM 1520 mode/address was selected as a default because it was the first
IBM 46XX family scanner to support UPC/EAN, Code 39 and Interleaved 2
of 5. The Version 11 scanner formats Codabar, Code 128, and Code 93 using
the Code 39 function code designation supported by the IBM device driver for
this scanner type. Other emulation modes currently available are the IBM
3687-2 Port 17 fixed scanner and the Port 9B IBM 4500 CCD hand-held bar
code reader. One of these other emulation modes may be needed depending on
which operating system (4680.OS, 4690.OS, POS/DOS or DOS/RIPPS) is in
use at the site.
Note: The IBM 4683 and IBM 4684 terminals have a good proven track
record of supplying power to Metrologic scanners. The IBM 4693
and IBM 4694 terminals may be restricted from supplying power to
certain scanner models. Specifically, Metrologic currently
recommends using an external power supply for the scanner when
connecting to an IBM 4694. Metrologic has no recommendations at
this time for IBM 4693 terminals.

Configuring the Scanner
Located in the Version 11 scanner are two computer boards. One board is for
decoding and the other for 46XX IO processing. The decode board is
configured using ScanSet™ or ScanSelect™ while the IO board is configured
with an internal DIP Switch bank.
For UPC/EAN scanning, the decode board should be set as follows:
Enable IBM 4680 Communication
Enable UPC/EAN
Beep after Transmit
Enable Communication Timeouts
Transmit UPC-A Check Digit
Transmit UPC-E Check Digit
These settings configure the decode board to beep after transmitting the data to
the terminal device driver. If the data does not clear the communications buffer
within two seconds, it is discarded without giving the operator a good scan
indication. This accommodates newer versions of the IBM device drivers that
enable/disable scanning in many different situations.
The default setting of the interface board is to emulate the IBM 1520 hand
scanner that supports UPC/EAN and alphanumeric code types. The following
is a list of switch settings for the internal interface board that handles the
46XX SIOC communications.
There are eight DIP switches on the board that are both software and hardware
switches.
Switch 1 Switch 2 Emulation Mode
OFF OFF Port 5B, IBM 1520 Model 2 Laser Scanner
(default setting)
OFF ON Port 9B, CCD (IBM 4500/Opticon)
ON OFF Port 17, IBM 4014 Adaptor for 3687-2 to 468X
ON ON Reserved
Switch 3 Reserved (Should be OFF)
Switches 4, 5, 6, and 7 Must be ON
Switch 8 Should be OFF (Reserved)
