Detection Capabilities: Can detect open or closed contact closure. Provides an OPEN/CLOSED indication in software.
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
Module input: Input amplifier detects resistance across input jack. Resistances from 0 to 15K ohm produce CLOSED condition in software. Resistance above 15K ohm produce OPEN condition in software.
Input contact connector: 2.1 mm jack
Operating temperature/humidity range: -40 º C to +60 º C (-40 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.
Communications Protocol: Sensorsoft Device Protocol, Version 2.0
Error control: 16 bit CRC (cyclic redundancy checking) for detection of communication errors between the device and host computer.
