5.8 Ethernet Network Connections

Note. Ensure that permission has been granted for
installation of new devices on the network. If in doubt,
consult the System Administrator before connecting
the instrument.
To connect the instrument into an Ethernet network, use a single
network cable to link it to the network hub. The connection is
made using a standard RJ45 connector at the rear of the unit –
see Fig. 5.5.
Table 5.2 shows the signals carried by each pin of the
connector:

Note. To prevent signal degradation, the maximum
cable length between 10BaseT network devices is
limited to 100m. If longer cable runs are required
between devices, repeaters or gateways must be used
to boost signal strengths.
The instrument uses standard Ethernet and web standards and
can be connected in a number of network configurations
including:
• Direct connection to a computer – see Fig. 5.13
• Connection to a network hub – see Fig. 5.15
• Connection to a dial-up router – see Fig. 5.16
• Connection to an internet gateway – see Fig. 5.17
