Description
Adsorptive gas inlet
Attaches the analysis gas supply.
Ethernet port
Connects the analyzer to a network enabling notifications via e-mail
of analysis completion, and to monitor analysis results using a web
browser. A straight-through or shielded cross-over ethernet cable
can be used since the analyzer will adapt to either type.
Helium inlet port
Attaches the helium gas supply.
Keypad connection
Connects the keypad to the analyzer.
Power connector
Connects the analyzer to the power supply.
Power switch
Powers the analyzer on and off.
RS-232 connector
Enables usage of a serial line for data transmission. This port can
also be used to attach an analytical balance for automatic trans-
mission of the sample mass. See
for details on transferring the mass value to the analyzer. See
for the pin assignment for the RS-232
port.
