5. Input Power:
The eMAX-MR62e is powered by one of two ways (jumper selected, J5):
•
Power is supplied via the Ethernet connection using PoE or PoE+.
•
Local 12 Vdc power supply, TB4-3 (VIN), TB4-4 (GND).
6. Communication Wiring:
Communication between the LP/ EP controller and the eMAX-MR62e is Ethernet (10Base
T/100Base-TX).
It is not recommended to connect the eMAX-MR62e to a public intranet.
7. OSDP Reader Wiring:
Connector TB7 of the eMAX-MR62e Module has connections for the 2-wire RS-485 OSDP
communication bus as well as 12 Vdc to power the OSDP readers. Up to four (4) OSDP readers are
supported on the eMAX-MR62e. The four (4) Readers can be used to control two (2) Doors/Portals
in an In/Out (paired) Reader mode for each door. The 12 Vdc output is limited to .5 A maximum.
The OSDP reader wiring diagram below shows the use of a 2-pair cable for data and power. If this
cable cannot support the voltage/current requirements, a 1-pair cable of sufficient gauge must be
used for power. See specification section.
The RS-485 termination jumper, J4, is only installed if the eMAX-MR62e is at one end of the
communication bus. Only devices at each end of the communication bus are terminated. Never
install termination to more than two devices on the communication bus.
When powering any remote device(s) by the eMAX-MR62e, care must be taken not to exceed the
maximum current available. Cable gauge must also be evaluated. See specifications section for
details
