Each Axis controller supports up to two readers, called Reader 1 and Reader 2 in Security Center Config Tool. The readers can use either Wiegand (default) or OSDP protocol. For OSDP, the reader must be wired to the first set of reader data A-/B+.
The following chart shows which set of connectors correspond to which reader on the Axis controller.
NOTE: This pin chart only shows up if the Axis controller is disconnected to the Synergis™ unit.
