Position the LGD Compact module at the location where the measurement will be carried out and where
computer, power supplies and gas delivery systems can be installed. For customer support and system service
it is ideal if the computer also can be connected to the internet.
To allow simplified connectivity for evaluation a cable integrating both, system power supply and RS232, are
provided (straight RS232 version, not crossed). The DB15 plug on the right-hand side in Figure 7 connects to
the mainboard of the instrument (mainboard connector in Figure 8), while the DB9 connector on the left-hand
side in connects to the computer.
The electronic housing has two 15pol D-Sub connectors, one with two rows used for power supply and
communication (J1) and the other one (three rows) for connection to the sensor module (J2).
