The CIM provides the following advanced features:
•
Dedicated Microprocessor-based design provides fast operation without restricting
RTU operation.
•
One CIM module can provide interface to a complete networked RTU system. This
leads to a single telephone line connection per site rather than typical multiple line
solutions.
•
Internal 14.4 kbaud modem available for direct connection to telephone system.
•
Flexible design provides two fully configurable serial ports.
•
Standard plug-in telephone RJ45/RJ11 type jacks and DB9 computer ports provide
simple interconnection to system.
•
The ability to callout to a THS host station or pager when an RTU fault occurs frees
the user from continual monitoring. It also allows for immediate remote response to
problems.
