10.6 Optional Modem Installation

Remote communications with a Hydran 201i System or a Hydran 201R Model i can be

CAUTION

10.6.2 Verifying Communications between the Two Modems

Once the modems are set up, proceed as follows to verify modem communications:
1. Power up the host computer.
2. Start the Hydran Host software.
3. If not already done, use this software to prepare the communication with the
Hydran 201Ti's by entering the definition of all H201Ti's in the network according
to the identification numbers previously assigned. For details, see the Hydran
Host Software Manual.
4. Enter the model name and configuration string of the modem in the Host Config
window of the Hydran Host software (see the Hydran Host Software Manual).
5. In the Hydran Host software, enter the telephone number and the communication
speed of the H201Ci's modem in the Power Stations Set-Up window (see the
Hydran Host Software Manual).
Note: The communication speed assigned to the power station in the Hydran Host
software must be the same as the one set in all H201Ti's in the local network.
6. If the H201Ti's Call OnAlarm command is used, program the H201Ci's modem
with the telephone number of the host computer's modem.
7. If not already done, set the communication speed of the H201Ti's. To do so,

The modems supplied by General Electric should be connected
to an analog line only. Using a non-analog line (for example,
digital, PBX, Multi-line) will damage the modem.
When using a modem, a solid-state station protector (model
Circa 1360B or equivalent) must be installed on the modem
telephone line within 20 meters of the Hydran 201Ci Controller
to ensure proper operation of the modem during network
disturbances.
