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.
