13�1 Physical Network Components; 13�2 Internet Settings - Honeywell Midas User Manual

13 Internal Web Server
The Midas gas detector unit utilizes an Ethernet
®
port with the TCP/IP protocol as standard. The
Midas can function as a HTML web page server
®
and these web pages can be viewed on external
computer equipment (PC, PocketPC etc.) by
using a standard software program, i.e.; Microsoft
Internet Explorer. These web pages replicate the
user interface on the front panel of the Midas
more flexible and friendly format for diagnostic and
data entry purposes. The web pages also contain
additional features not available via the keypad.
This procedure explains how to view web pages
for a single Midas which is connected to a single
®
PC only. Of course it is possible to connect
hundreds of Midas units to an Ethernet network.

More information may be required from the local IT
department and Honeywell Analytics as appropriate.
13.1 Physical Network Components
The Ethernet 100BaseT physical network is
intended to connect computers to other computers
through hubs. For this reason, a Midas
communicate directly with a PC using a standard
cable. This problem can be overcome by using a
special "cross-over" Ethernet cable or by using a
'hub' or 'switch' and two standard (straight through
wire connections) Ethernet cables. An example of
a cross-over cable is the Belkin A3X126 family. An
example of an Ethernet switch is the Linksys SD205.
13.2 Internet Settings
Communications requires knowledge of the IP
address and netmask of both the Midas
PC. Unless the Midas
®
and the
®
is connected to a network
®
with a DHCP server, the addresses must be set
manually. To view or set the IP address of the Midas
see Section
address of a PC is detailed in the following example
using a PC loaded with Microsoft™ Windows XP and
Internet Explorer version 5.0 or higher as illustrated
by Diagram 13-1. In the usual case the netmask for
both computers should be set to 255.255.255.0. The
most-significant three bytes of the IP address must
in a
®
be identical and the least-significant byte must be
unique. For example, if the IP address of the Midas
was set to 169.254.60.47 (the factory default) then
an appropriate IP address for the PC would be
169.254.60.42.
