The analyzer has several ways to communicate the outside world, see Figure 10-15.
Users can input data and receive information directly via the Front Panel keypad

analyzers RS232 & RS485 I/O ports or an optional Ethernet port. The analyzer can
also send and receive different kinds of information via its External Digital I/O
connectors and the three Analog Outputs located on the Rear Panel.
