2. Code Converter Problems<br />
After hardware modification of all types of controller boards (a new type of<br />
Manchester-Code-Converter IC chip has been implemented), sporadic LAN<br />
disconnections between mainframe and control panel can occur.<br />
Controllers of hardware indices shown in the following list can be affected by this<br />
phenomenon. How to find out the hardware index, please refer to chapter 6<br />
