Communication and Interface
Analog and Digital Interface
The Main and Auxiliary connectors provide the analog outputs for concentrations and other
variable signals. Digital Status outputs, Control inputs and Calibration drive signals are also
provided. There are four analog outputs, whose type (mA or specific voltage range) and signal
assignments are assignable from the Setup menu. See the following tables for pin numbers and
functions.
Serial Interface
The 9-pin Serial Interface connector provides RS-232 remote control and data access to the
analyzer via the AK protocol.
Network Port
The TCP/IP port allows the analyzer to be accessed via a network connection. The analyzer
requires a static IP address that is settable from the Setup menu. Either AK or Modbus protocol
can be used to access the analyzer remotely.
