Note: When a CPE330 is configured as a CPU320, Ethernet properties cannot be configured.
However, the embedded Ethernet ports may be used with the default IP Addresses.
Connection to a 10Base-T / 100Base Tx Network
Either shielded or unshielded twisted pair cable may be attached to a port. The 10Base-T/100Base Tx twisted
pair cable must meet the applicable IEEE 802 standards. Category 5 cable is required for 100BaseTX operation.
The Ethernet port automatically senses the speed (10Mbps or 100Mbps), duplex mode (half-duplex or full-
duplex) and cable configuration (straight-through or crossover) attached to it with no intervention required.

Note: Pin assignments are provided for troubleshooting purposes only. 10Base-T/100Base-Tx
cables are readily available from commercial distributors. We recommend purchasing
rather than making 10Base-T/100Base-Tx cables.
The programmer is connected to the Ethernet Interface through a 10Base-T or 100Base-Tx network.
