2.8 Input Power
The MR62e is powered by one of two ways (jumper selected, J5)
•
Power is supplied via the Ethernet connection using PoE or PoE+.
Local 12Vdc power supply. TB4-3(VIN), TB4-4(GND).
Communication between the EP controller and the MR62e is Ethernet
(10Base T/100Base-TX). It is not recommended to connect the MR62e to a
public intranet
.
2.10 OSDP Reader Wiring
TB7 has connections for the 2-wire RS-485 OSDP communication bus and 12 Vdc to
power the OSDP readers. Up to four OSDP readers are supported on the MR62e. This
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 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.
Note:
When powering any remote device(s) by the MR62e, care must be taken not to
exceed the maximum current available. Cable gauge must also be evaluated. See
specifications section for details.
