a. At least one H201Ti in a local network must be set to an identifi-
cation number between 1 and 5 (inclusively).
5. The serial number of each component of the Hydran 201i System, the value of the
H201Ti's parameters and a general description of the installation (transformer
number, power station number, etc.) should be logged and kept in a safe place.
6. The communication parameters must be identical at both ends of the communication
channel. In addition the communication speed of both modems must be the same as
the H201Ti's and the host computer. Refer to the Hydran Host Software Manual.

Cabling

1. The maximum length allowed for each cable is as follows:
• The total maximum length for all supervisory links cables in a single
Hydran 201i System (between a H201Ci Controller and its H201Ti's) is 1,200 m
(4,000 ft).
• The total maximum length for all RS-485 link cables between all H201Ci Controllers in
a local network is also 1,200 m (4,000 ft).
• The length of the RS-232 link cable must not exceed 7.7 m (25 ft).
2. All cables that connect the Hydran 201i System's components should be run in steel
conduits. The shield of all cables should be grounded at one end only or at the
indicated locations. Routing and shielding of the RS-485 link cable are particularly
