Product Overview
The MS1890 is a rugged, high performance hand-held area imaging bar code
scanner that utilizes a high-resolution CMOS imaging sensor for superior image
quality. The MS1890 utilizes Omniplanar, Inc.’s Swiftdecoder
®
software for
reliable decoding of both 1D and 2D bar code symbologies. Sharp images can
be captured and transmitted in a variety of outputs, including: .jpg, .bmp, and .tiff.
Omnidirectional scanning capabilities and an extended depth of field provides
aggressive scanning of all standard 1D, RSS, PDF417, microPDF, EAN/UCC
Composite, Matrix and Postal Codes symbology types. Firmware updates are
easily loaded via Flash ROM.
The MS1890 provides a built in object detection sensor (IR) that instantly turns
on the scanner when an object is presented within the scanner’s field of view.

The PowerLink Cable
Connecting
Important: If the PowerLink cable is not fully latched, the unit can
power intermittently.
Figure 2. Connecting the PowerLink Cable
1. Insert the 10-pin RJ45 end of the cable into the socket on the MS1890.
There will be an audible click when the connector locks into place.
2. Gently pull on the cable strain relief to insure the cable is installed.
3. Install the cable boot cover over the cable strain relief and onto the end of
the unit’s handle.
Disconnecting
Before removing the cable from the scanner, Metrologic recommends that the
power on the host system is off and the power supply has been disconnected
from the PowerLink cable.
Figure 3. Releasing the PowerLink Cable
1. Remove the cable boot to reveal the cable connection.
2. Locate the small ‘pin-hole’ on the handle of the unit near the cable.
3. Bend an ordinary paperclip into the shape shown above.
4. Insert the paperclip (or other small metallic pin) into the small ‘pin-hole’.
5. There will be a faint ‘click’ when the lock releases. Pull gently on the
strain-relief of the PowerLink cable to remove the cable from the unit.

Labels
Each scanner has a label located on the underside of the head. This label
provides the unit’s model number, date of manufacture, serial number, CE, and
caution information. The following figure gives an example of the label and its
location.
Figure 4. Label Samples and Location
Caution:
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/IEC
60950-1.
To maintain compliance with standard CSA-C22.2 No. 60950-1/UL 60950-1 and norm
EN/IEC 60950-1, the power source should meet applicable performance requirements for
a limited power source.
Maintenance
Smudges and dirt can interfere with the proper scanning of a bar code.
The output window should be routinely cleaned with glass cleaner sprayed onto a
lint free, non-abrasive cloth.

1. Turn off the host device.
2. Plug the male 10-pin RJ45 end of
the PowerLink cable into the 10-pin
socket on the MS1890. There will be
an audible click when the connector
lock engages.
3. Slide the protective cable boot up the
cable, over the connector and onto
the end of scanner handle.
4. Connect the 9-pin D-type connector
of the communication cable to the
proper COM port of the host device.
5. Plug the power supply into the power
jack on the PowerLink cable.
Check the AC input
requirements of the power
supply to verify the voltage
matches the AC outlet. The
outlet must be located near
the equipment and be easily
accessible.
6. Connect AC power to the transformer.
7. The MS1890 will start to initialize. All LEDs (yellow, white, and blue) will
light for approximately 2 seconds then start to flash alternately. When the
scanner has finished initializing the LEDs will stop flashing and the unit will
beep three times indicating that the scanner is ready for use.
8. Turn on the host device.
Plugging the scanner into a port on the host system does not guarantee
that scanned information will be communicated properly to the host
system. The scanner is shipped from the factory configured with default
settings. Please refer to the MetroSelect Single-Line Configuration
Guide ( MLPN 00-02544) or MetroSet2’s help files for instructions on
changing the scanner’s configuration. In addition, please check that the
scanner and host system are using the same communication protocol.

Multi-Try Trigger Mode*
1. The IR detects an object in the IR
activation range and automatically turns
on linear illumination.
2. Aim the scanner’s line of light
over the bar code.
3. Pull the trigger to initiate scanning.
The scanner’s light output will start to
flash as it attempts to scan the bar code.
If the trigger is released the
scanner will stop trying to scan.
4. When scanner successfully reads the
bar code it will beep once, the white
LED will flash and the decoded data will
be transmitted to the host.
* For additional configurable modes of operation, please refer to the Area
Imaging Bar Code Supplemental Configuration Guide ( MLPN 00-02281).

Audible Indicators
When the MS1890 is in operation, it provides audible feedback. These sounds
indicate the status of the scanner. Eight settings are available for the tone of the
beep (normal, 6 alternate tones and no tone). To change the tone, refer to the
MetroSelect Single-Line Configuration Guide,
MLPN 00-02544 or MetroSet2’s
help files.
One Beep
When the scanner successfully reads a bar code it will beep once and the
white LED will turn on indicating data is being transmitted.
If the scanner does not beep once and the white light does not turn on, then
the bar code has not been successfully read.
Short Razzberry Tone
This tone is a failure indicator (see Failure Modes on page 15).
Long Razzberry Tone
This tone is a failure indicator (see Failure Modes on page 15).
Three Beeps - At Power Up
When The MS1890 first receives power it will start an initialization sequence.
All LEDs (yellow, white, and blue) will light for approximately 2 seconds then
start to alternately flash. When the scanner has finished initializing the LEDs
will stop flashing and the unit will beep 3 times indicating that the scanner is
ready for use.
Three Beeps - Configuration Mode
When entering configuration mode, the white LED will flash while the scanner
simultaneously beeps three times. The white and blue LEDs will continue to
flash while in this mode. Upon exiting configuration mode, the scanner will
beep three times, and the LEDs will stop flashing.
When configured, 3 beeps can also indicate a communications timeout during
normal scanning mode.
When using single-code-configuring, the scanner will beep three times:
a normal tone followed by a short pause, a high tone and then a low tone.
This indicates that the single configuration bar code has successfully
configured the scanner.

S CANNER O PERATION
Visual Indicators
The MS1890 has three LED indicators (yellow, white and
blue) located on the top of the scanner. When the scanner
is on, the flashing or stationary activity of the LEDs
indicates the status of the current scan and the scanner.
No LEDs are Illuminated
The LEDs will not be illuminated if the scanner is not
receiving power from the host or transformer.
The scanner is in stand-by mode. Present a bar code to
the scanner and the blue LED will turn on when the IR
detects the object.
Steady Blue
The blue LED is illuminated when the scanner is active and linear illumination
is on or when the scanner is attempting to decode a barcode.
Steady Blue and Single White Flash
When the scanner successfully reads a bar code it will beep once and the
white LED will turn on indicating data is being transmitted.
If the scanner does not beep once and the white light does not turn on, then
the bar code has not been successfully read.
Steady White
When the scanner successfully reads a bar code it will beep once and the
white LED will turn on indicating data is being transmitted.
After a successful scan, the scanner transmits the data to the host
device. Some communication modes require that the host inform the
scanner when data is ready to be received. If the host is not ready to
accept the information, the scanner’s white LED will remain on until the
data can be transmitted.
Alternating Flashing of Blue and White
This indicates the scanner is in configuration mode. A short razzberry tone
indicates that an invalid bar code has been scanned while in this mode.

Failure Modes
Long Razzberry Tone – During Power Up
Failed to initialize or configure the scanner. If the scanner does not respond
after reprogramming, return the scanner for repair.
Short Razzberry Tone – During Scanning
An invalid bar code has been scanned when in configuration mode or the
trigger has been pulled too fast.
