9.3.1

Local Communications

One or more Hydran 201R Model i's and/or Hydran 201i Systems are connected to a host
computer using an RS-232 serial communication link (DB-9 connector). This connection
can be done as follows (see Figure 9-2 on page 9-5):
• By connecting the host computer to the DB-9 connector of a Hydran 201Ti. In this case,
the communication can only be established with this particular H201Ti.
• By connecting the host computer to the DB-9 or USB connector of a Hydran 201Ci
Controller. This connection gives access to all H201Ti's linked to this H201Ci and also,
if present, to all H201Ti's of all H201Ci's in this local network.
The maximum distance for an RS-232 local link is 7.5 m (25 ft).
9.3.2

Remote Communications (via Modem)

One or more Hydran 201R Model i's and/or Hydran 201i Systems are linked to a host
computer by connecting a modem to a Hydran 201Ci Controller's DB-9 connector and a
telephone system (private or public); see Figure 9-2 on page 9-5.
A Hayes-compatible modem can be pre-installed and pre-set at the factory in a H201Ci. For
details on settings, refer to the modem procedure located in the English/Procedures folder
of the Hydran 201i System installation CD. A typical communication configuration with a
modem is shown in Figure 9-3 on page 9-7.
The modems supplied by General Electric Canada should be

connected to an analog line only. Using a non-analog line (for
example, digital, PBX, Multi-line) will damage the modem.
