Communications and Networking
The Hydran M2-X can be used as a stand-alone unit or within a network of up to
32 Hydran M2-X
’s. Both configurations can be connected locally to a laptop
computer, or remotely to the host computer through a modem or Ethernet (via
copper wires or fiber optic).
5.1
Network Configuration Overview
As shown in the Figure below, a Hydran M2-X network is a daisy chain of Hydran
M2-X
’s. The Hydran
M2-X
’s in the network ar
e connected together using an RS-485
link (for technical details, see Section D-1).

LED transmitters for fiber optic are classified as IEC 60825-1
Accessible Emission Limit (AEL) Class 1. Class 1 devices are
considered eye safe to the unaided eye. Do not view directly with
optical instruments.
In a network, the Perception software can communicate with each Hydran M2-X
individually because each one is identified by a unique identification number
(
Monitor ID
parameter) set by the user (see Section 3.2.7.1).
The Hydran M2-X
’s manage all communications automatically (transmission and
reception). Data transmission is half-duplex (one direction at a time, from a single
source).
To host computer
with Perception
software via either:
•
Ethernet (wire
or fiber optic)
•
Modem
interface.
•
Or RS-485 link
to Hydran 201Ci
controller
Daisy chain: RS-485 link, isolated, 1 triad
Maximum number of Hydran M2-Xs: 32
Maximum total length of cables: 1,200 m (4,000 ft)
