HYDRAN 201CI-C COMMUNICATIONS CONTROLLER

Figure 3-1 on page 3-1 shows one possible configuration of a Hydran 201i System. It
consists of three components:
• A host computer
• The Hydran 201Ci-C Communications Controller, which is described in detail in
Section 3.1 on page 3-1
• The Hydran 201Ti Intelligent Transmitter, already described in Chapter 2

Features

The Hydran 201Ci-C is meant specifically to interface a network of up to
128 Hydran 201Ti's to a computer via a single RS-232 or USB link, or an optional modem.
As opposed to the Hydran 201Ci-1 (Section 3.2 on page 3-7), the H201Ci-C does not have
a display, nor does it provide alarms or analog outputs.
Up to four H201Ti's (typically, a transformer bank [A, B, C] and sometimes an auxiliary)
can be connected to each H201Ci-C through the isolated supervisory link. A maximum of
