(typically ATS0; see Section 3.2.7.2).
3. The modem receiving this command dials the telephone number previously
stored in its register 0; this number is redialed until the connection with the
host computer’s modem is established. Then, no other message is sent; the
host computer has the responsibility to communicate with the Hydran M2-X
in alarm condition.
4. The Perception software displays the alarm states and updates its data bank.
5. The user must acknowledge the alarm in the Perception software and take
the appropriate measures.
5.1.3 Remote Ethernet Communications With a Host Computer (via
Copper Wires or Fibre Optic)
For Ethernet communications, a single Hydran M2-X or a network of Hydran M2-
X’s can be linked directly to the host computer (see Figure 5-4 below) running the
Perception software. To do this, one Hydran M2-X in the daisy chain must be linked
to the host computer using an Ethernet cable to the Ethernet port, or a fiber optic
cable to the fiber optic port.
In the case of fiber optic, the Rx and Tx connections on the Hydran M2-X must be
connected respectively to the Tx and Rx connections of the fiber optic converter used
with the PC.
