CommLink II Interface
The CommLink II Interface provides for communications between the MiniLink
communication interfaces installed on the system. The CommLink II is required for
proper communications, even if a PC is not used. Locate the CommLink II near the
computer or modem if they are installed on the system. The cable connections between
the CommLink II and the computer or modem should be kept to less than twenty-five
feet. The CommLink II comes complete with computer and modem cables, and a plug-in
power supply.
