Communications With a Host Computer, Using an RS-232 Serial Communication
Part 17997 Rev. 6, March 2011 9-5
• In the H201C i -1: To the terminals 21 to 24 of the Main Terminal Block (item 6 in
Figure 3-6 on page 3-11).
The installation of an RS-485 local network link cable is described in Section 9.5.1 on
page 9-9.
9.3 COMMUNICATIONS WITH A HOST COMPUTER, USING AN RS-232
SERIAL COMMUNICATION LINK
A Hydran 201T i , a Hydran 201R Model i , a Hydran 201 i System or a local network can be
connected, either locally or remotely (through a modem), to a host computer via an RS-232
serial communication link. Figure 9-2 on page 9-5 illustrates the various ways to connect a
host computer to a Hydran 201R Model
i .
The computer (or modem) can be attached to any Hydran 201C i Controller on a local
network. General Electric Canada’s Hydran Host software is the easiest way to
communicate directly with the H201C
i (’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:
• In the H201T i : To the DB-9 Male RS-232 Connector (item 5 in Figure 2-2 on page 2-5)
on the back of the CPU module.
