1. General:
The eMAX-MR51e Reader Interface Module provides a direct IP network connected, dual card reader interface
to an eMAX-EP Area Controller and the Maxxess eAxxess or eFusion Access Control System. The eMAX-MR51e
provides control of a single door with paired readers (Reader IN & Reader OUT), or two separate controlled
doors with a Card Reader to enter and a REX to exit. The eMAX-MR51e is Power over Ethernet (PoE) capable,
and provides interfacing for TTL/Wiegand/*RS-485 type readers to the door hardware. The on-board Ethernet
connection with PoE support enables an easy and cost-effective installation.
Note: For UL installations, POE powered devices shall not be used. Power for these devices
must be provided by a UL 294 listed, class 2 rated, power limited source (12Vdc).
The eMAX-MR51e provides two (2) Card Reader connection ports. The first reader port can accommodate a
reader that utilizes Wiegand (data0/data1), Magnetic Stripe (clock/data), or *2-wire RS-485 electrical signaling
standards, as well as one or two-wire LED controls, and buzzer control (one wire LED mode only). The second
reader port can accommodate a reader that utilizes Wiegand or Magnetic Stripe signaling, along with one or
two-wire LED controls, and buzzer control (one wire LED mode only).
The eMAX-MR51e provides two (2) configurable Form-C relay outputs to be used for door strike control or alarm
signaling. The relay contacts are rated at 5A @ 28Vdc, dry contact configuration. Four configurable inputs are
also provided for monitoring the door contacts, exit push buttons, or other alarm contacts. The eMAX-MR51e
requires power from PoE, or local 12Vdc. The eMAX-MR51e may be mounted in a 3-gang switch box with a
special mounting plate that is supplied with the unit. Alternatively, the eMAX-MR51e may be mounted in the
Maxxess enclosure on a din rail.

DIP Switches:
All S1 switch settings are unassigned and are reserved for future use. Set all switches to the OFF position.
4. Input Power:
The eMAX-MR51e is powered by one of two ways (jumper selected):
•Power can be supplied via the Ethernet connection using Power over Ethernet (PoE), fully compliant to IEEE
802.3af .
OR
•Power can be supplied via a local 12Vdc power supply (minimum 1A), wired to TB5-3 (VIN), TB5-4 (GND).
Note: For UL installations, POE powered devices shall not be used. Power for these devices
must be provided by a UL 294 listed, class 2 rated, power limited source (12Vdc).
Approved UL 294 listed, class 2 rated, power limited power supplies:
Altronix model: AL1012ULXPD4CB
Altronix model: AL1012ULXPD8CB
Altronix model: AL1012ULXPD16CB
GROUNDING
Care should be taken to ensure proper grounding of all Power Supply connections. Ensure that the 12Vdc Power
Supply that is providing power to the eMAX-MR51e is properly grounded to an Earth Ground point.

August 20, 2012 eMAX-MR51e-Man Rev B 7 of 17
5. Communication Wiring:
Communication between the eMAX-MR51e and the eMAX-EP controller is via TCP/IP Ethernet (10Base-
T/100Base-TX). The Communication connection is via the on-board Ethernet RJ45 connector. Cabling should
be standard Cat5 or Cat6 network cabling. It is recommended that the network connection to the eMAX-MR51e
is connected to the same Network Switch as the eMAX-EP Area Controller to which it is assigned to.
6. Reader Wiring:
The first reader port supports Wiegand, magnetic stripe, and *2-wire RS-485 electrical interfaces. The second
reader port supports Wiegand and magnetic stripe electrical interfaces. Power to the first reader is 12Vdc and
is current limited to 150mA. The second reader may be powered from the auxiliary power output on TB5-1 and
TB5-2. Readers that require different voltage or have high current requirements should be powered separately.
Refer to the reader manufacture specifications for cabling requirements. In the 2-wire LED mode, the Buzzer
output is used to drive the second LED. Reader port configuration is set via the host software.
NOTE: When powering a remote device(s) from the eMAX-MR51e, such as a Card Reader, care must be taken not
to exceed the maximum current rating available from the board. Size/gauge of the cable used must also be
verified. Consult the Specifications section of this document for details.

August 20, 2012 eMAX-MR51e-Man Rev B 8 of 17
7. Input Circuit Wiring:
Typically, the inputs of the eMAX-MR51e are used to monitor door position switches, request to exit devices, or
auxiliary alarm contacts. The operational defaults are; Input 1 for the Door 1 contact, Input 2 for the Door 1
Request to Exit, Input 3 for the Door 2 contact (or spare), Input 4 for the Door 2 Request to Exit (or spare). Input
circuits can be configured as Supervised or Unsupervised circuits. When unsupervised, reporting consists of
only the open or closed states.
When configured as Supervised, the input circuit will report not only open and closed, but will also detect and
report open circuit, shorted circuit, grounded circuit, and foreign voltage. A supervised input circuit requires
two resistors be added to the circuit wiring to facilitate proper reporting. The standard supervised circuit
requires two (2) 1K Ohm, 1% resistors and should be located as close to the sensor as possible.
Note: Grounded and foreign voltage states are not a requirement of UL 294 and therefore not verified by UL.
The input circuit wiring configurations shown are supported but may not be typical:
8. Relay Circuit Wiring:
Two relays are provided for controlling door lock mechanisms or alarm signaling. The relay contacts are rated
at 5A @ 28Vdc, dry contact configuration. Each relay has a Common pole (C), a Normally Open pole (NO) and a
Normally Closed pole (NC). When controlling the delivery of power to the door strike, the Normally Open and
Common poles are used. When momentarily removing power to unlock the door, as with a mag lock, the
Normally Closed and Common poles are used. Check with local building codes for proper egress door
installation.
Door lock mechanisms can generate feedback to the relay circuit that can cause damage and premature
failure of the relay. For this reason, it is recommended that either a diode or MOV (metal oxide varistor) be
used to protect the relay. Wire should be of sufficient gauge to avoid voltage loss.

August 20, 2012 eMAX-MR51e-Man Rev B 9 of 17
Diode Selection:
Diode current rating: 1x strike current. Diode breakdown voltage: 4x strike voltage.
For 12Vdc or 24Vdc strike, diode 1N4002 (100V/1A) typical.
MOV Selection:
Clamp voltage: 1.5x Vac RMS. For 24Vac strike, Panasonic ERZ-C07DK470 typical.
See documentation included with locking device regarding suppression diode requirements.
NOTE: It is possible for the eMAX-MR51e to provide power for a 12Vdc Door Lock/Strike. However, care must be
taken not to exceed the maximum current rating available from the board. Size/gauge of the cable used must also
be verified. Consult the Specifications section of this document for details.

August 20, 2012 eMAX-MR51e-Man Rev B 10 of 17
9. Status LEDs:
At power up, LEDs 2 through 6 are turned ON then OFF in sequence.
After the above sequence has completed successfully, the eMAX-MR51e goes to the “waiting for IP address”
mode:
LED

Off-line: .2 second ON, .8 second OFF
2
Waiting for IP address: .5 second ON, .5 second OFF

Note: There is no LED for IN4.
After the eMAX-MR51e has received its IP address, the following table describes the LEDs in the normal running
mode. If the communication is lost, the eMAX-MR51e reverts back to the “waiting for IP address” mode:

Note: There is no LED for IN4.
10. Configuring the eMAX-MR51e
The eMAX-MR51e is an IP Network connected device. Therefore, when adding the eMAX-MR51e to the
eAxxess or eFusion Access System, the hardware (MAC) address and the IP address will be required for the
device. The MAC address must be entered using a colon ( : ) as a separator between digits, not a dash ( - ).
{ i.e. 11:22:33:44:55:66 } The device panel address may be 0 –31.
It is recommended that the IP address be within the same subnet as the eMAX-EP controller that this eMAX-
MR51e is assigned to. The eMAX-MR51e must be no more than one hop from its eMAX-EP controller.

August 20, 2012 eMAX-MR51e-Man Rev B 11 of 17
The eMAX-EP controller will automatically assign the IP address to the eMAX-MR51e device after saving the
record. See section 9 for LED status confirmation of IP setting.
