THEORY OF OPERATION Model 360E Instruction Manual
10.4. Interface
The analyzer has several ways to communicate the outside world, see Figure 10-16. Users can input data and
receive information directly via the Front panel keypad and display. Direct communication with the CPU is also
available by way of the analyzer’s 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.
