10.3 Communications with a Host Computer

A Hydran 201Ti, a Hydran 201R Model i, a Hydran 201i System or a local network can
be connected, either locally or remotely (through a modem), to a host computer via an
RS-485 serial link, RS-232 serial link or a USB communication link. Figure 10-2 illustrates
the various ways to connect a host computer to a Hydran 201R Model i.
Figures 10-3 and 10-4 illustrate the various ways to connect a host computer to a
Hydran 201 Ti.
The computer (or modem) can be attached to any Hydran 201Ci Controller on a local
network. General Electric's Hydran Host and Perception software is the easiest way to
communicate directly with the H201Ci(s) or the network.
Note: A remote host computer can be used to supervise more than one local network of
Hydran 201i Systems.
The RS-232 serial communication link cable can be connected at the following locations:
