cotton module. This device contains the RFID radio, antenna cable, and antenna
inside the enclosure.
There are two versions of this device that are identical except for the RFID
engine’s operating region – 866MHz or 915MHz.
This device is intended to be installed on the Cotton machine at the factory,
as a service part, and as a field kit.
