Ethernet Setup
You may need to ask your network administrator for advice about setting up the Ethernet
connection.
Ethernet set up is not affected by cold booting the PP420.
9.1
Connection
The Ethernet link uses a 10 base-T connection on an RJ45 connector. The PP420 will usually be
connected to a network switch (or hub or router). It is also possible to connect it direct into the
network port on a PC by using a swapover cable.
9.2
MAC Address
The PP420 MAC address is:
0x00.0x0B.0x75.0x01.0xNN.0xNN.
9.3
IP Address
The PP420 needs an IP address to communicate over Ethernet. There are two ways to get an IP
address; either programmed into the unit or using DHCP.
Most networks use a DHCP server. If there is a PC on the network, You may be able to find out
whether a PC on the same network uses DCHP as follows:
•
Go to Control Panel
•
Select Network Connections
•
Right click on Local Area Connection. Select Properties
•
From the list, select Internet Protocol (TCP/IP), press Properties
If “Obtain an IP address automatically” is set, then DHCP is probably used. However, there may
be an alternative fixed IP address on the “Alternative Configuration” tab.
You can find out what IP address is being used by a PC at any time by:
•
Go to Control Panel
•
Select Network Connections
•
Right click on Local Area Connection. Select Status
•
Select the Support tab. The IP address is displayed
When using a fixed IP address, you must ensure that you use an IP address that is not being used
by any other device on the network. It is usual to keep the first three numbers of the IP address
the same as other devices and to change only the last number. For example, if you have a
network consisting of a PC (IP address 192.168.1.35) and two PP420s, you might give them
addresses 192.168.1.201 and 192.168.1.202.
