3�1 Communication options
The WMPro has two communication ports – one for
Ethernet and the other for a modem. You can connect
the Ethernet port directly to a computer, a network or a
broadband modem. You will always use the Ethernet port
to congure a new WMPro for the rst time.
The modem port (RS232) is used for remote access via a
modem. You can use a standard dialup modem or a GSM/
GPRS modem for wireless access. If a WMPro has a modem,
you can connect to it.
3�2 Network connection
You can connect a WMPro to a LAN temporarily in order
to congure it, or permanently as part of a larger sys-
tem. To congure a new WMPro you will need to use a
computer connected to the same LAN. This user guide
assumes the computer is running Windows 95, 98, 2000,
XP or NT. Other operating systems are also supported. The
procedure is more or less the same, although the details
may dier depending on the operating system.
3�2�1 PC connection
The IP address factory setting for a new WMPro is 10.0.48.94. Start by letting your computer know
that your WMPro is connected to the same network. Because all WMPro devices come precongured
with the same address, you will only be able to connect one new WMPro at a time.
You will need a computer with a web browser in order to change settings and access the infor-
mation in a WMPro. This section explains how to connect a WMPro to a computer or network.
First, there is an outline of the various options that are available, and you will nd out how to get
started quickly and easily. If your computer is connected to a LAN, the easiest method is de-
scribed in 3.2. If there is no network, you can use a direct connection instead, as described in 3.3.
3.4 explains how to browse to a WMPro, and in 3.5 you will learn how to change network settings.
More advanced communication options are discussed in 3.6 onwards. Turn to section 18 for de-
tails of RS485 communication with external units and WMShare.
Ethernet indicators
The Ethernet port has two LEDs –
LINK (yellow) lights up when the
WMPro is connected to a network,
and LAN (green) ashes when
there is network trac.
RS232 indicators
The RS232 port has four data traf-
c and handshake LEDs.
