The MS-3000 MicroStar Reader


1.0 Introduction

The MS-3000 MicroStar reader is intended for installation on a window mullion or a door frame, on or off metal, in proximity applications where an unobtrusive reader is required. The MS-3000 reader is compatible with a PXL-500P, or with an NXT/NXT-MSC controller - via an NXT-RM3 (Reader Interface Module).

The reader provides an audible beeper and a multi colored LED to annunciate the reader's status:
  1. Amber - to indicate normal operation awaiting an access event
  2. Green - to indicate a valid card has been presented or the door has been unlocked for access
  3. Red - to indicate an invalid card has been presented or the door is in an alarm condition.

The MS-3000 MicroStar Reader is housed in a black, weatherproof, shock resistant package. The reader provides optimum performance when mounted on aluminum; read range is slightly reduced if the reader is not mounted on aluminum.

3.0 Mounting Instructions

Three holes need to be drilled to mount the MS-3000 reader (see Figure 1). One large hole (0.875" - 7/8") accommodates the beeper and the reader cable. Two small holes are for mounting the reader on the mullion or door frame (hole size is dependent upon the size of the mounting screw).

Note: Do not mount the reader near sources of Electromagnetic Interference (EMI) such as a computer monitor. EMI degrades a reader's read range.


4.0 Connections

The MS-3000 reader does not require configuration; there are no switches or jumpers to set. The MS-3000 reader is normally connected to a PXL-500P via the TB5 or TB6 connectors, or to an NXT/NXT-MSC controller via an NXT-RM3 (Reader Interface Module). All connections needed to support the reader are made through the reader's cable. 

4.1 PXL-500P Reader Wiring

The "A" reader connects to TB5, pins 1 through 6 (TB5 has a seventh pin, but no connection is made to that pin). The "B" reader connects to TB6, pins 1 through 6 (TB6 has a seventh pin, but no connection is made to that pin).

4.2 NXT-RM3 Module Reader Wiring



5.0 Installation Verification

The reader's power is provided by the controller, so the reader is powered on when the controller is powered on. The reader's normal state is to display a constantly on amber LED as it waits for a card or tag to be presented.

To verify the reader is functioning correctly, pass a Keri proximity card or a Keri Key tag within a few inches of the reader. The reader will beep and either the green or red LED will flash (depending upon whether or not the card/tag has been enrolled at the controller) and then return to steady amber.

To verify the reader's read range, hold a Keri proximity card or a Keri Key tag parallel to the reader, about 1 foot away and slowly draw the card/tag in toward the reader. Note the distance when the reader recognizes the card. The MS-3000 reader's range will be up to 4 inches for a card and 2 inches for a tag depending upon the installation conditions, the material on which the reader is mounted, and whether it is a card or a tag being read.

Note: Due to the physical size difference between cards and tags, tags provide approximately 50% less read range than cards. Refer to the Troubleshooting the Reader Installation section if the reader is not functioning properly.


6.0 MS Reader Troubleshooting

The reader does not recognize a card/fob

  1. The reader wiring may be incorrect - Refer to section 4 to ensure the reader wiring to the controller is correct.
  2. The reader may not receiving proper power from the controller - Verify the voltage being supplied to the reader is between 5 and 12v.
  3. The reader may be mounted too close to a source of electromagnetic interference (EMI) - Devices such as computer monitors radiate electromagnetic interference that affects read range. When possible, relocate either the reader or the device to provide a greater distance between the two.
  4. The wrong credential type may be being presented - The MS series readers are only compatible with Keri K-series credentials. The K-series credentials will have the letter K printed in the top-right corner preceding the imprint number.
    K-series credentials are: PKT-10x fobs, KC-10X credentials, MT10XM credentials and MT10XP credentials.
  5. The reader shield may not be grounded correctly - The shield/drain wire of any reader/peripheral cables MUST be terminated to one of the following points-any corner screw attaching the controller to the enclosure, Pin 3 of TB10, the green ground lug (J6) on the controller applies to NXT controllers only), or the ground lug of the enclosure.  Failure to properly earth ground the reader/peripheral drain wire may result in unreliable communication or operation of the attached peripheral.
  6. The lock may be powered from the same power-supply as the controller - It is advisable for the locks to be powered from its own power-supply because the noise generated by locks can be transmitted from the powered line and can interfere with the controller or potentially damage it.
  7. Transorbs may not be installed at the locks - Transorbs are provided with the controller ship kit. They are used to protect the controller from voltage spikes induced on the port wiring by absorbing the excess voltage and slowly releasing it back into the circuit. Keri strongly recommends wiring in the transorbs provided with the controller ship kit.


The Reader Has a Short Read-Range

  1. The controller may not be grounded correctly - Refer to the controller grounding document and check that the controller has a quality earth ground connection. Visit help.kerisys.com and use the search terms 'Grounding' to locate the appropriate document.
  2. The shield wire on the reader cabling may be opened - Verify the shield line from the controller to the reader is one continuous, connected line and properly connected to the controller.
  3. The reader may be mounted too close to a source of electromagnetic interference - Devices such as computer monitors radiate electromagnetic interference that affects read range. When possible, relocate either the reader or the device to provide a greater distance between the two.
  4. The reader may be mounted too close to a source of electromagnetic interference (EMI) - Devices such as computer monitors radiate electromagnetic interference that affects read range. When possible, relocate either the reader or the device to provide a greater distance between the two.
  5. The reader may be powered by a switching power-supply - Switching power supplies are known EMI sources. Change to a linear, regulated power supply or position the reader far away from the power-supply.
  6. The lock may be powered from the same power-supply as the controller - It is advisable for the locks to be powered from its own power-supply because the noise generated by locks can be transmitted from the powered line and can interfere with the controller or potentially damage it.
  7. Transorbs may not be installed at the locks - Transorbs are provided with the controller ship kit. They are used to protect the controller from voltage spikes induced on the port wiring by absorbing the excess voltage and slowly releasing it back into the circuit. Keri strongly recommends wiring in the transorbs provided with the controller ship kit.
