Cyrano Controller Firmware R3.2L
December 03, 2008

Bug Fix
---------
Corrected the following problem:

* (KB80442) SNAP-LCSX, SNAP-LCSX-PLUS, SNAP-LCM4, and M4RTU controllers labeled 
"Rev. 2": A new loader (version R4.0C) and firmware (version is R4.1f) fix 
a problem with the real time clock losing 20 hours if power was cycled when 
the clock displayed any hour that began with 20 some hours (2x:xx:xx). Only 
controllers with the new clock chip are affected. Please contact Opto 22 Product
Support to determine whether or not you have the new clock chip. To contact
Product Support, see How To Get Help at the end of this readme.

Enhancement
-----------

the following controllers:
