2.4.1. i-PORT M350-2
The i-PORT M350-2 is a reader for the i-Q350 and i-B350 series of
IDENTEC SOLUTIONS’s Response and Broadcast Sensors. Built into a
compact housing, the i-PORT M350-2 reads and writes data to the sensors
at distances of up to 500 meters (1640 feet) on two antennas. Connection
to the host system is established via a RS422 interface, resulting in the
capability to connect up to 8 readers in a Daisy Chain using commercially
available CAT 5 cables and connectors.
A simple master/slave protocol enables data exchange. Not only does the
protocol contain the data received from the sensor but it can also provide
information about the time of data reception, field strength and information
about the number of times the sensor has been received by the reader.
