If you have an IP network of computers,
you can connect loggers to
one or more computers and then access
them remotely via the
network. You can configure the loggers,
monitor current readings
and download stored data via the network
using EnviroMon for
Windows.
To do this, you first install an agent
program on each of the remote
computers that will be connected to
loggers, then run EnviroMon for
Windows on the local computer. There are
currently agents for the
following operating systems:
Windows 3.11
Windows 95/98/NT/2000
Linux (Red Hat 5.2/6)
Before starting, you need to find out
the network names of the
computers that you wish to connect to.
If a computer is called fred,
you can check that the local computer
can talk to them by typing in
ping fred.
To run an agent program on Windows 95,
open a DOS box and type
in the following command:
c:\pico\emagnt32.exe -c2 [-i1051]
[-b57600]

-c2 is for COM2. Change the number as
appropriate. The
parameters in brackets are optional. The
-i option sets the IP port
number: use 1051 unless that clashes
with some other service. The
-b option sets the baud rate.
The computer will start the program
minimised. If you restore it, it
displays a count of IP messages received
and of responses from the
logger. You can use this to identify
problems.
To run an agent program on a Windows 95
computer each time it
starts up:
· Click on Start
· Select Settings
· Select Taskbar
· Select Start
Menu programs
· Select Add
· Type in the
command line c:\pico\emagnt32.exe -c2
· Click on Next
· Select the
Startup group

To switch EnviroMon to IP operation:
· go into the
configuration menu (select File then Configuraton)
· select
Equipment
· change the
connection type to IP network
· Set the IP port
number to 1051
· Enter the name
of the computer that the logger is connected to
· Press OK
You can now use the logger as if it were
connected directly to your
computer.
Please note that EnviroMon for Windows
will request data
continuously from the the logger: this
may cause a lot of network
traffic. To reduce this, set the
RefreshDelay parameter in envimon.ini.
See the EnviroMon driver help file for
technical information about IP
networking.
