6.1.2 Direct Connection
This section describes how to connect a pc directly to the instrument.
WIRING
Connection is made from the Ethernet connector at the rear of the Instrument to an
Ethernet RJ45 connector, usually located at the rear of the pc. The cable can be either a
‘cross-over’ or ‘straight through’ type.
Once wired correctly, and powered up, it is necessary to enter a suitable IP address and subnet mask into
the Comms configuration of the Driver Module. This information can be found as follows:
1.
At the pc, click ‘Start’. ‘All Programs’, ‘Accessories’, ‘Command Prompt’
2.
When the Command Prompt box appears, type IPConfig<Enter>
The response is a display, such as that shown below, giving the IP address and Subnet mask of the pc.
Choose an address in the range covered by these two values.
A subnet mask element of 255 means that the equivalent element of the IP address must be used
unchanged. A subnet mask element of 0 means that the equivalent element of the IP address may
take any value between 1 and 255 (0 is not allowed). In the example below, the range of IP addresses
which may be chosen for the Driver Module is 123.123.123.2 to 123.123.123.255. (123.123.123.0 is not
allowed and 123.123.123.1 is the same as the pc’s address, and may therefore not be used.)
Figure 3.1.2b IP Config command
3.
In Network.Interface configuration (
) enter the selected IP address and the subnet mask
(as it appears in the command prompt window) in the relevant parts of the menu.
4.
Check communications by ‘pinging’ as described in section 6.1.1, above.
Once the link to the instrument has been verified, iTools can be started (or shut down and re-started), and
the Scan toolbar icon used, to ‘find’ the instrument. The scan can be stopped at any time by clicking on
the Scan icon a second time.
See section 6.2 for more details of the scan procedure.
