2. Theory of Operation
The HIB module does not provide any direct monitoring or control functions. Its
purpose is to bridge the MCN network and the PC’s serial COM port.
The HIB module is used along with CTI Product’s MCN Remote Comparator
Display (MCN RCD) software (reference 2) to provide a PC based operator
station. The monitoring and control functions are performed by the MCN RCD
software.
The HIB supports multiple baud rates from 9600 baud up to 38400 baud,
selectable from the front panel.
The HIB has two modes of operation. One is local mode, where the HIB is
connected directly to the PC’s COM port. The second mode is remote mode,
where the HIB is at another location and a modem link is used to connect the HIB
to the PC’s COM port.
