3.4.2 i-PORT M350
The i-PORT M350 is a reader for the i-Q350 series of ILR
®
Response Tags.
Built into a compact metal housing, the i-PORT M350 reads data from and
writes data to the i-Q350 tags at distances of up to 500 meters
(1500 feet). 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 tag but it can also provide
information about the time of data reception, field strength and information
about the number of times the tag has been received by the reader.
