PP8xx LED Controller - User Manual

Ethernet address
You may need to ask your network administrator for advice about setting
up the Ethernet connection.
The application note APP923 – Troubleshooting Ethernet problems is
available from
www.gardasoft.com/Downloads
.
The Ethernet set up of the PP82x is not affected by cold-booting the
controller.
8.1
IP address
The PP82x needs an Internet Protocol (IP) address to communicate over
Ethernet. There are two ways to get an IP address; either programmed
into the unit or using DHCP.
For DHCP mode, the PP82x acquires its IP address, subnet mask, and
gateway address from the DHCP server. Otherwise the PP82x has a fixed
IP address, subnet mask, and gateway address.
DHCP mode or the IP address can be set or read using the
GardasoftMaint program available from
www.gardasoft.com/Downloads
.
The GardasoftMaint window is shown below:

PP8xx LED Controller - User Manual
GardasoftMaint allows you to view the controllers on your network, change
their IP addresses and upgrade their firmware if it becomes necessary. In
the messaging section of GardasoftMaint, you can communicate with your
controller using the commands explained in
Section 10, Command
configuration
. You can also open the selected controller's web pages by
clicking the
Link to controller webpage
button. For more information
about the PP82x's web pages, see
Section 9, Web page configuration
.
8.1.1
MAC address
The PP82x's MAC address is in the form:
0x00.0x0B.0x75.0x01.0xNN.0xNN.
8.1.2
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:
i. Go to the Control Panel.
ii. Select
Network Connections
.
iii. Right click on
Local Area Connection
. Select
Properties
.
iv. 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
following the steps below:
i. Go to the Control Panel.
ii. Select
Network Connections
.
iii. Right click on
Local Area Connection
. Select
Status
.
iv. Select the
Support
tab. The IP address is displayed.
8.1.3
Fixed IP address
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
PP82x's, they could be allocated addresses 192.168.1.201 and
192.168.1.202.
