Reader interface: -Reader power (jumper selectable): 12 VDC ±10% regulated, current limited to 150mA for each reader or 12 to 24 VDC ±10% (input voltage passed through) current limited to 150mA for each reader. Data inputs: TTL compatible inputs, magnetic stripe and Wiegand standards supported RS-485 mode: 9600 to 38400 bps, asynchronous, half-duplex, 1 start bit, 8 data bits, and 1 stop bit. LED output: TTL levels, high > 3V, low < 0.5 V, 5mA source/sink max. Buzzer output: TTL levels, high > 3V, low < 0.5 V, low=active, 5mA source/sink max.- - -Cable Requirements: - - - -Power: 1 twisted pair, 18 to 16 AWG Ethernet: CAT 5 TTL Reader: 22 to 16 AWG, depending on length and requirements RS-485 (I/O device ports): 24 AWG stranded twisted pair(s) with an overall shield, 4000 feet (1219 m) maximum RS-485 (Reader port): 24 AWG stranded twisted pair(s) with overall shield, 2000 feet (609.6 m) maximum Alarm Input: 1 stranded twisted pair, 30 ohms maximum, typically 22 AWG @ 1000 feet (304.8 m)
