CommLink II Interface
The CommLink II Interface acts as the network communications loop master for the
Plus system. See Figure 2-25 for dimensional data. It also provides for an on-site
computer hook-up or Remote Link interface connection to the system for remote
communications. For the Plus system, the CommLink II is wired and it’s jumper must be
set for multiple loop operation. See
Figure 2-27 for correct jumper setting connection
and wiring instructions.
If an on-site computer is to be connected to the system, locate the CommLink II near the
computer. Also, if a Remote Link is to be used it must be located close to the CommLink.
The CommLink II comes complete with computer and modem cables, and a 110VAC
plug-in power supply. The RemoteLink is also supplied with a 110 VAC plug in power
supply. The cable connections between the CommLink II and the computer or Remote
Link must be made with the factory supplied cables. These cables are designed
specifically for the CommLink and RemoteLink connections.
DO NOT USE any other
cables to connect them to each other or the computer as the system will not function. See
Figure 2-27 for information about connecting to the Remote Link and personal
computer.
