Ethernet communication
(RT220, RT420, RT820F)
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 RTxxx.
See Application note APP923 (available from
) for
troubleshooting Ethernet problems.
10.1
Connection
The Ethernet link uses a 10Base-T connection on an RJ45 connector.
The RTxxx is usually connected to a network switch, hub or router, but
you can connect it directly into the network port on a PC using a
crossover cable.
10.2
IP Address
The RTxxx 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.
For DHCP mode, the RTxxx acquires its IP address, subnet mask and
gateway address from a DHCP server. Otherwise the RTxxx has a fixed
IP address, subnet mask and gateway address.
DHCP mode or the IP address can be set and read using the
GardasoftMaint program available at
.
The GardasoftMaint window is shown overleaf:
