10/100 BASE-T Interface

General

The module’s 10/100 BASE-T interface is a standard RJ45 connector. In an industrial environment, use a cable with the following characteristics:

The following straight-through ConneXium cables fit these requirements for connecting terminal devices:

Description	Reference		Length, m (ft)
Description	Low Smoke Zero Halogen	UL/CSA CMG	Length, m (ft)
Straight-through cable with RJ45 ends	490 NTW 000 02	490 NTW 000 02 U	2 (6.6)
	490 NTW 000 05	490 NTW 000 05 U	5 (16.4)
	490 NTW 000 12	490 NTW 000 12 U	12 (39.4)
	490 NTW 000 40	490 NTW 000 40 U	40 (131.2)
	490 NTW 000 80	490 NTW 000 80 U	80 (262.5)

NOTE: If there is a connection via a shielded cable, the connector casing on the module is linked up to the ground connection.

Line Speed

The different line speeds that are available for the BMX NOE 01x0 and the integrated Ethernet port of the BMX P34 2020/2030/20302 CPUs are:

The user can not configure the line speed. Characteristics of speed adaptation are:

Auto-sensing and auto-negotiation allow the Ethernet module to quickly configure itself to the local Ethernet switch's speed and duplex mode.
The negotiated speed between two Ethernet devices is limited to the speed of the slower device.
