Typical Connections for Mx-1 Controller

Like DIGI*TRAC Controllers, the Mx-1 controller can connect to a number of input and output devices. For details, see the following topics:
When referring to those topics, note that the layout of the Mx-1 controller’s terminals (as shown in Figure 3-2 in section “Mx Controller Main Board”) is different from the layout of the terminal blocks of the DIGI*TRAC M2 or M8 Controller.
All interconnecting devices must be UL Listed, low-voltage Class 2 power limited.
Wiring for the Door
An Mx-1 controller provides the following terminals for the door:
Two 8-pin Wiegand reader terminals for connecting readers or keypads which have a Wiegand interface.
A 5-pin OSDP RS-485 Readers terminal for connecting keypads or readers which have an OSDP RS-485 interface. (Only one of these terminals is needed, because when the door has an optional exit reader with an OSDP RS-485 interface, it is wired “through” the entry reader with an OSDP RS-485 interface.)
A 3-pin Door Input terminal for analog inputs such as multi-state alarm inputs from the line module. (There is also a 3-pin Aux. Input terminal which can be used for a second analog input.)
A 3-pin Door Relay terminal for two-state outputs such as a magnetic lock or electric strike.
The following diagrams show the basic wiring for a normally closed electric door strike when it is connected to an Mx-1 controller in either:
Wet Mode, where power is supplied by the Mx-1, or
Dry Mode, where power is provided by an external power supply.
A 3-pin Aux. Relay terminal which can be used to control external alarm or auxiliary devices (such as activating an audible alarm, turning on lights, or initiating the recording of surveillance video).
The number and types of readers you will be using on the door dictates which reader terminals you need to use:
For only an entry reader with a Wiegand interface, use the Wiegand Entry Reader terminal.
For only an entry reader with an OSDP RS-485 interface, use the OSDP RS-485 Readers terminal.
For an entry reader and an exit reader, both with a Wiegand interface, use the Wiegand Entry Reader terminal for the entry reader and use the Wiegand Exit Reader terminal for the exit reader. For details, see “Wiring Diagram for Wiegand Readers”.
For an entry reader and an exit reader, both with an OSDP RS-485 interface, use the OSDP RS-485 Readers terminal, with the exit reader wired “through” the entry reader. For details, see “Wiring Diagram for OSDP Readers”.
For an entry reader with an OSDP RS-485 interface and an exit reader with a Wiegand interface, use the OSDP RS-485 Readers terminal for the entry reader and use the Wiegand Exit Reader terminal for the exit reader.
To avoid possible damage to your Mx-1 controller, make sure it is powered off before you add or remove a reader connected to a Wiegand terminal.
The following figure shows a typical wiring configuration for a door managed by an Mx-1 controller, where an entry reader is required on the outside of the protected area, and a Request To Exit button (or a motion detector) is used on the inside to leave the protected area. Note that if the protected area is an anti-passback zone, you will instead need to use an exit reader on the inside of the protected area.

For a more detailed wiring diagram, see the Mx-1 Quick Install Guide.
Always refer to the actual wiring diagram provided with the specific reader that you are installing.
The following wiring diagram shows how to connect a TS reader to an 8-pin Wiegand terminal on an Mx-1 controller.

Wiring Diagram for OSDP Readers
The following figure shows an example wiring diagram for an Mx-1 controller and a pair of Identiv’s OSDP readers, which are the entry reader and the optional exit reader for a door. Note that:
The exit reader is wired “through” the entry reader for a door, so it shares the OSDP RS-485 Readers terminal on the Mx-1 controller.
On the exit reader, a jumper wire is needed between P1.1 and P1.4 (or between the orange and the black wires on the pigtail model) to designate that it is the exit reader. For details, see “Example Wiring Diagram for an RREB”.
The correct value for the OSDP Address field in the Velocity software depends on the reader’s manufacturer, and whether the reader is used for entry or exit. For example:
An Identiv reader’s address should be set to 0 when it is the door’s entry reader, and set to 1 when it is the door’s optional exit reader.
A Veridt reader’s address should be set to 1 when it is the door’s entry reader, and set to 2 when it is the door’s optional exit reader. (Values 3 through 126 are not used; a unique address is derived from the RS-485 port number on the RREB in a particular controller.)
The diagram shows power being supplied to the readers from the Mx-1 controller. But depending on the types and quantity of readers (and other devices) being used, you might need to power some of the remotely located readers from an external power supply. For more information, see “Power Provided at the Mx-1 Controller’s Reader Terminals”.
