Future updates willbe documented and available online through the Help link in the KX IIRemote Console interface.Note: Some topics in this section reference other multiple Raritandevices because various devices are impacted by the information.Java Runtime Environment (JRE)Important: It is recommended that you disable Java™ caching andclear the Java cache. Please refer to your Java documentation orthe KVM and Serial Access Clients Guide for more information.The LX, KX II, KX II-101 and KX II-101-V2 Remote Console and MPCrequire the Java Runtime Environment™ (JRE™) to function since theRemote Console checks the Java version. If the version is incorrect oroutdated, you will be prompted to download a compatible version.Raritan recommends using JRE version 1.6 for optimum performance,but the Remote Console and MPC will function with JRE version 1.6.xand later with the exception of 1.6.2.Note: In order for multi-language keyboards to work in the LX, KX II, KXII-101 and KX II-101-V2 Remote Console (Virtual KVM Client), install themulti-language version of JRE.Appendix D Informational Notes
