Example of OSDP shield termination at MATCH connector
RS-485/OSDP Reader wiring can be sensitive to electromagnetic interference so it is recommended to use a good quality shielded cable.
Strip only enough of the cable jacket and shielding to allow for proper wiring of the connector.
The shield foil/braid should be stripped to the same length as the cable jacket.
The shield wire should be stripped to the same length as the signal conductors.
The shield wire should can be terminated along with the reader ground in the provided location of the RS-485/OSDP Reader connector.
Another option to terminate shield wire would be to terminate the shield wire at an unused MATCH shield terminal as shown above. Ensure the exposed shield wire is covered with shrink tubing.
Ensure exposed shield wire does not come into contact with any other shield wires, the metal enclosure, or any other metallic surfaces.
Shrink tubing can be used on exposed shield wire to ensure unwanted contact with metal surfaces.
