iCHIME Module
Operating Manual
Background.
The iCHIME is 2.4GHz bi-directional radio transceiver. A User may configure the device to operate as a
Radio Frequency Identification Device (RFID) to support tracking shipping containers in a worldwide
supply chain using the Marine Asset Tag Tracking System (MATTS) communication protocol. An iCHIME
module utilizes a low power, wireless, radio operating in the 2.4 GHz band as its primary mode of
communication. The wireless radio operates in compliance with IEEE Standard 802.15.4-2006. The
iCHIME utilizes the same radio, processor, and User interface software as iControl's iTAG . The iCHIME
also supports the same command list as iControl's iTAG. The iCHIME is User configurable to periodically
transmit the iCHIME's status via the MATTS radio network. The module may operate as stand alone
device or may be used as a radio transceiver for devices that communicate data as a part of a larger
system.
There are no physical connections to the iCHIME other than two charging contacts for the rechargeable
LI button cell battery.
