Divar | Installation Manual | Hardware setup EN | 4-5
Ethernet connection
The standard RJ-45 Ethernet socket is used to connect the unit directly to a PC
or to a network. The Ethernet is also used to connect to an ATM/POS bridge
unit. To connect directly to a network hub, use a straight-through network cable.
To connect directly to a PC, use the supplied cross-over network cable. Consult
with your local IT personnel for the specific type of cable needed. The cable
length from node to node is limited to 100 feet (30.5 meters) maximum length
and 6 feet (1.8 meters) minimum length.
Network configuration
The Divar is delivered with the DHCP function switched on, so IP addresses are
assigned automatically if the network server uses DHCP. (Refer to the
System
settings/Connectivity/Network setup menu.)
