M3000 Installation Guide
•
Set the reader voltage (JP1) to 5 V.
•
Wire the Reader power lead to the Power output port (J6) on the Power/Communications board
instead of to the 2SRP board.
To wire a 12 V reader:
1.
Mount the reader. Refer to the manual that came with your reader for specific mounting
instructions.
2.
Run cable from the reader to the controller. Bring each reader cable through the appropriate
knockout hole in the controller enclosure. Allow some slack wire for servicing the cables and for
plugging cable into an adjacent slot for troubleshooting.
3.
Remove 8 inches (20.32 cm) of insulating material from the cable. Unwrap shielding and tie all
shields together. Connect the communications cable shield to the ground stud adjacent to the
cable entrance knockout of the cabinet enclosure. For more details, refer to figure
Typical
Installation Using Shielded Cable/drain Wire - Outside and Inside the Enclosure on page 20 .
4.
Place the appropriate wires to the appropriate screw terminal on the 2SRP reader board. Refer to
the reader wiring diagrams in this section. Pairing of cables is very important.
Note:
The 2SRP board has built-in pull-up resistors. Do not install any external pull-up
resistors.
5.
Label each cable end with the Controller Address Number/Device or Reader Number.
