Introduction and Identification When using the MH941 scanner with a decoder not manufactured by Metrologic, scanner operation is dependent upon your decoder. Since there are many decoders available, refer to your decoder’s documentation concerning scanner requirements and operation. When using a Metrologic hand-held scanner with one of Metrologic’s fixed scanners, the scanner will operate as follows: ! The IR signal extends approximately eight (8) inches beyond the output window.
Unpacking List The following will be found in the shipping carton: ! Installation and User’s Guide ! MH941 Hand-Held Laser Scanner If anything is missing or to order additional items, contact your dealer, distributor or call Metrologic’s Customer Service Department.
Connecting the MH941 Hand-Held Scanner to the Fixed Scanner and Host Device In order for the MH941 scanner to maintain compliance with applicable standards, all circuits connected to the scanner (Example: power supply, host system, etc.) must meet the requirements for SELV (Safety Extra Low Voltage) according to EN60950. 1. Make sure the host system is turned off. 2. Connect the head cable of the MH941 hand-held scanner to the cable terminated with a 9-pin connector attached to the fixed scanner. 3.
Connecting the MH941 Hand-Held Scanner to the Decoder/Controller In order for the MH941 scanner to maintain compliance with applicable standards, all circuits connected to the scanner (Example: power supply, host system, etc.) must meet the requirements for SELV (Safety Extra Low Voltage) according to EN60950. Since there are many different types of decoders, refer to your decoder’s documentation to connect the decoder to your host system.
Parts of the MH941 Scanner Becoming familiar with the features of the MH941 scanner will help when operating the scanner. The following illustration and list explain the pertinent parts. Figure 2 Laser Output Window The laser beam emits from this aperture. Head Cable Ths cable is terminated with a 9-pin squeeze connector. The following functions are decoder /controller dependent. Green LED When the green light flashes on, the scanner has read the bar code successfully.
Audible Indicators There are audible indications that signal the status of your scanner. These indications are dependent upon the decoder being used. The function of these indications may not work as described below if using a decoder not manufactured by Metrologic. When the scanner is in operation, it will provide warnings with audible indications. These sounds signal the status of the scan and scanner.
Signaux acoustiques Il existe des signaux acoustiques qui vous informent sur l'état du scanner. Ces signaux dépendent du décodeur que vous utilisez. Il peut arriver que les fonctions de ces signaux ne correspondent pas à celles qui suivent si vous utilisez un décodeur qui n'a pas été construit par Metrologic. Quand le scanner est en service, il émet des signaux acoustiques qui vous informent sur l'état de palpage et de scanner.
Akustische Anzeigen Es sind akustische Anzeigen vorhanden, die Ihnen Aufschluß über den Scannerstatus geben. Diese Anzeigen sind abhängig von dem von Ihnen verwendeten Dekodierer. Es kann sein, daß die Funktionen dieser Anzeigen nicht den nachfolgend angegebenen entsprechen, falls Sie einen Dekodierer verwenden, der nicht von Metrologic hergestellt wurde. Ist der Scanner in Betrieb, so sendet er akustische Signale aus. Diese Signale geben Ihnen Aufschluß über den Abtast- und Scannerstatus.
Segnali acustici Sono previsti dei segnali acustici che Vi informano sullo stato dello scanner. Questi segnali dipendono dal decodificatore da Voi utilizzato. Se utilizzate un decodificatore che non è stato fabbricato dalla Metrologic è possibile che le funzioni di questi segnali non corrispondano a quelle qui di seguito indicate. Se lo scanner è in funzione esso emette segnali acustici. Questi segnali Vi informano sullo stato della scansione e dell’apparecchio.
Visual Indicators There are visual indications that signal the status of your scanner. These indications are dependent upon the decoder being used. The function of these indications may not work as described below if a decoder not manufactured by Metrologic is being used. Located at the top of the scanner are two LEDs: red and green. The flashing or stationary lights of the LEDs signal the status of the scan and scanner. No Red or Green Light There are two reasons why the two LEDs will not be illuminated.
Signaux optiques Il existe des signaux optiques qui vous informent sur l'état du scanner. Ces signaux dépendent du décodeur que vous utilisez. Il peut arriver que les fonctions de ces signaux ne correspondent pas à celles qui suivent si vous utilisez un décodeur qui n'a pas été construit par Metrologic. Sur la partie supérieure du scanner se trouvent une diode LED rouge et une diode LED verte. Les diodes rouge et verte clignotantes ou allumées vous informent sur l'état de palpage et de scanner.
Optische Anzeigen Es sind optische Anzeigen vorhanden, die Ihnen Aufschluß über den Scannerstatus geben. Diese Anzeigen sind abhängig von dem von Ihnen verwendeten Dekodierer. Es kann sein, daß die Funktionen dieser Anzeigen nicht den nachfolgend angegebenen entsprechen, falls Sie einen Dekodierer verwenden, der nicht von Metrologic hergestellt wurde. Auf der Oberseite des Scanners befinden sich zwei Leuchtdiodenanzeigen: eine rote und eine grüne. Die blinkenden bzw.
Segnali ottici Sono previsti dei segnali ottici che Vi informano sullo stato dello scanner. Questi segnali dipendono dal decodificatore da Voi utilizzato. Se utilizzate un decodificatore che non è stato fabbricato dalla Metrologic è possibile che le funzioni di questi segnali non corrispondano a quelle qui di seguito indicate. Sulla parte superiore dello scanner si trovano due diodi luminosi: uno rosso e uno verde.
Labels The MH941 is a CDRH Class II laser system and an IEC Class I Laser System. Your unit will have a CDRH Class II caution label and an LASERKLASSE 1 label affixed below the model number. The model number label is found on the bottom of the scanner’s head. Found directly below the output window at the front of your unit is a red avoid exposure label. The following are examples of these labels: The model number includes the scanner number and revision level.
IR Sensor Activation This function is decoder/controller dependent. The scanning process is initiated by an infra red (IR) device that is found below the laser output window. The signal it projects extends approximately eight (8) inches beyond the output window (Refer to Figure 3). The IR device remains active as long as power is applied to the unit. When the unit remains dormant for a time, the laser will turn off. In this stage, the scanner’s computer is on “stand by”.
Scan Field The depth of field for the scanner is from the face of the output window to five (5) inches (Refer to Figure 4). If the scanner is in the stand, a bar code must be presented to the scanner. When holding the scanner, position the output window within five inches of the bar code.

Maintenance Smudges and dirt can interfere with the proper scanning of a bar code. Therefore, the output window will need occasional cleaning. 1. Spray glass cleaner onto lint free, non-abrasive cleaning cloth. 2. Gently wipe the scanner window.

Appendix B MH941 Scan Head Pin Assignments Pin 1 Signal Name Flip Sense Function A square wave output signal that changes polarity when the scan mirror drive circuit changes the motor direction. The frequency is approximately 19 Hz to achieve a nominal 38 flips/scan per second. Note: The polarity and mirror direction do not necessarily change at the same time. This is an open collector output capable of sinking 25 mA via an external pull up resistor connected to a voltage not to exceed +20 VDC.
4 Reserved 5 Proximity Detect The proximity detect is a momentary grounding switch. The controlling computer should provide a +5±.25 VDC pull up which can be grounded when the proximity detect activates. This indicates that an object has moved within scanning rage. It is recommended that this signal be debounced for approximately 30 milliseconds. Note: This scan head was not designed to have the laser enabled continuously as might be desired if the scanner was in a permanent mounting fixture.
