If your device is equipped with the Ethernet module, you can switch to a

TCP

tab and connect with it’s IP

address and port 2101 or use

Locator

function to find all KMB devices connected to a LAN and simply chose

the SMC 144 device you want to connect to.

Press the ’Connect’ button. The program reads the settings from the connected device and displays it in the

summary window (figure 3).

Figure 3: ENVIS.Daq - connected instrument.

Category ’Instrument Settings’ includes a number of parameters, which are arranged in tabs according to its

relation. User can configure the following in the individual tabs:

ˆ

Identify

Object

- Is a number or name of object (generally a text string), where was performed the measure-

ment. This is a basic identification element, that will organize the measurement archive in a database
