LMI Technologies Inc. Release Notes 4.11.6.2 The c+s 3155 sensor is now supported as a drop-in replacement for the c+s 3150 sensor. Note: it is not possible to downgrade a system containing a c+s 3155 sensor to a version of firmware older than version 4.11.6.2. LMI recommends upgrading all existing c+s 3x00 systems to version 4.11.6.2. The folder structure of the kClient installer has changed; binaries are now located in bin/win32, libraries in lib/win32. A bug in FireSync Dashboard that could result in the Dashboard crashing after 1-2 days of continuous operation has been fixed. Multiple simultaneous connections are now supported on FireSync Host Protocol Control and Management channels. Spot size has been added to c+s 3250 tracheid output messages (see manual for details). Message IDs for Web Mode output have been changed. Note, Web Mode is still under development and should not be used in production. The kLite sample application is now replaced by the Zen API (zApi folder). The Zen API provides classes that enable communication with FireSync devices via the FireSync Host Protocol (FHP). Zen is an open-source library that can be compiled for 32-bit and 64-bit editions of Windows and Linux. Documentation for the Zen library is included in the docs folder. A sample application that demonstrates use of the Zen API for c+s 3x00 sensors is included in the examples/console folder.
