Upgrading the Radio’s DCW
A Device Control Word (DCW) is a program written in the UtiliNet programming language. DCWs
execute within UtiliNet devices and provide the ability to control the device. The DCW interacts
with firmware and directs the radio to do things such as reboot or perform advanced functions.
For instance, the MCCTIME.hex DCW contains the current version of MCC
Helper. MCC Helper queries the radio to get its ID, and begins sen d ing
discovery packets to the assigned Take Out Poin t.
If you are upgrading to DCW version 1.16F, see “Field Upgrade to DCW 1.16 F ”
