Each reader port can accommodate a read-head that utilizes Wiegand, magnetic stripe, or 2-wire RS-485 electrical signaling standards, one or two wire LED controls, and buzzer control. Four Form-C relay outputs may be used for strike control or alarm signaling. The relay contacts are rated at 5 A @ 30 VDC, dry contact configuration. Eight (8) inputs are provided for monitoring the door contacts, REX inputs, and alarm contacts. The LNL-4420 requires 12-24 VDC for power.36.1InterfacesThe IDRC interfaces upstream with the access control software host system.Configuration data and event/status reports are exchanged with the host via 10-BaseT/100BaseTX Ethernet interface (Port 0). Additional I/O devices are communicated to via the downstream communication ports, 2- wire RS-485. The controller supports 64 downstream devices total (32 devices per downstream port).
