Preparing for Network Connections

When setting up your router, consider distance limitations and potential electromagnetic interference
(EMI) as defined by the applicable local and international regulations.
Network connection considerations are provided for several types of network interfaces and are
described in the following sections:
•
•

Ethernet Connections

The IEEE has established Ethernet as standard IEEE 802.3. The router supports the following Ethernet
implementations:
•
•
•

Serial Connections

RS232 and RS485 serial connections are provided by router serial ports, described in detail in the
"Router Hardware Description"

Exterior 10/100BASE-T Fast Ethernet Port

The router exterior Ethernet connector is compliant with Open DeviceNet Vendor Association (ODVA)
standards. Cables used with this port must also comply with the ODVA standards. ODVA-compliant
cables and connectors meet IP 67 ratings.

Check the power at your site to ensure that you are receiving power that is free of spikes and noise.
Install a power conditioner if necessary.
Confirm that the AC input power supply has a 110 VAC nominal, 1.0 A rms or 220 VAC nominal
0.5 A rms output sourcing capability.
