3.2 Switch Settings
The EN311 provides two connected switches that are used to switch between 10BASE5
and 10BASE2 networks, i.e., to select the connected network type.
(1) 10BASE5
Turning the two connected DIP switches on the front panel to the left allows a
10BASE5 network to be connected.
Figure 3-2 Switch Settings when a 10BASE5 Network is Used (front view)
(2) 10BASE2
Turning the two connected DIP switches on the front panel to the right allows a
10BASE2 network to be connected.

Caution
• The EN311 cannot be connected to both a 10BASE5 and a 10BASE2 network concurrently.
Do not connect a network cable of the unused type to the EN311. This can damage the
EN311 or cause it to malfunction.
• Do not change this switch setting while a data transfer is in progress. This can damage the
EN311 or cause it to malfunction.
• When changing this switch setting, turn both switches together at the same time. Only turn-
ing one of the switches at a time will not result in normal correct switching between the net-
works.
