CHAPTER
4

4.1 Internal Web Server

The Midas S2 gas detector unit utilizes an Ethernet port with the TCP/IP protocol as standard.
The Midas S2 can function as a HTML web page server and these web pages can be viewed on
external computer equipment (PC, PocketPC etc.) by using any Web browser, i.e.; Microsoft
Bing, Safari, or Google Chrome . These web pages replicate the user interface on the front panel
of the Midas S2 in a 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 S2 which is connected to a
single PC only. Of course it is possible to connect hundreds of Midas S2 units to an Ethernet
network. More information may be required from the local IT department and Honeywell as
appropriate.

4.2 Physical Network Components

The Ethernet physical network is intended to connect computers to other computers through
hubs. Midas S2 has a 10/100 Mbps Ethernet transceiver and supports Auto-MDIX. It supports
Auto-Negotiation for selecting the highest performance mode of operation. To use CAT5
standard or higher shield Ethernet cable is recommended for the highest efficiency
communication speed.

4.3 Internet Settings

Communications requires knowledge of the IP address and netmask of both the Midas S2 and
the PC. Unless the Midas S2 is connected to a network with a DHCP server, the addresses must
be set manually.
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 be identical and the least-significant byte must
be unique. For example, if the IP address of the Midas S2 was set to 192.168.0.14 (the factory
default) then an appropriate IP address for the PC would be 192.168.0.15.
