10.6. COMMUNICATIONS INTERFACE
The analyzer has several ways to communicate the outside world, see Figure 10-26. Users can input data and
receive information directly through the front panel keypad and display. Direct, two-way communication with the
CPU is also available by way of the analyzer’s RS232 & RS485 I/O ports (see Section 6.11 and 6.15).
Alternatively, an Ethernet communication option can be substituted for one of the COMM ports.
The analyzer can also send status information and data via the eight digital status output lines (see Section
6.15.1.1) and the three analog outputs (see Section 6.7) located on the rear panel as well as receive commands
by way of the six digital control inputs also located on the rear pane (see Section 6.15.1.2).
