Detection Capabilities: Can detect availability and loss of AC mains power.
    Maximum measurement rate: one reading every second
    Housing Dimensions: 8 cm (3.1") x 4 cm (1.6") x 2 cm (0.8")
    Housing Material: injection molded ABS thermoplastic
    Housing Colour: light gray
    Communications connector: 8 position modular jack, (accepts 8 position plug RJ45)
    Power source: Port-powered (RTS and DTR, both asserted)
    Power supply current drain: < 10 mA
    Power detector connector: 2.1 mm power jack, accepts plug from AC-DC power adapters such as P/N PA6109 or PA6209. The minimum voltage on this jack must be 7.8 volts DC for a PWR_OK reading. A voltage below this would give a PWR_FAIL reading. The continuous absolute maximum input voltage is 15 Vdc due to transient suppressor. Failure to use the recommended power adapters will void the warranty.
    Operating temperature/humidity range: 0 º C to +60 º C (32 º F to +140 º F) and < 90% RH (non-condensating)
    Communications Interface: RS232C using TX,RX,RTS,DTR and GND. One device per serial port.
    Maximum communications cable length: 305 m (1000 ft.) using recommended cable type. Low capacitance shielded cable or UTP is recommended.
    Firmware Version: 2.01
    Communications Protocol: Sensorsoft Device Protocol (SSDP) Version 2.0 and Version 3.0. For software that supports only Version 2 of the protocol a polling method is used. For software that supports Version 3 of the protocol a real-time method is used.
    Error control: 16 bit CRC (cyclic redundancy checking) for detection of communication errors between the device and host computer.
