4 Scorpion I Reader
The Scorpion I Reader contains the internal components of an RF Code Scorpion I
Reader and an Ethernet Client Bridge and is housed in a 12” x 8.5” x 2” painted,
aluminum chassis with screw-on cover. The reader works with Scorpion I Tags
that periodically transmit an encoded radio signal identity. The reader decodes
each tag’s signal and sends that information to the host processor, using the
Ethernet Client Bridge as a communication interface to the local area network
(LAN).
