Issuing Serial Commands to the Analyzer
You can use a PC running a communications program, such as HyperTerminal, to issue commands
to the Analyzer via a serial (RS-232) connection. For information on establishing a connection,
consult “Using HyperTerminal” on page 228 in the Appendix. The Analyzer accepts the following
serial commands:
RUN Start analysis
STP Stop analysis
When the Analyzer receives one of these commands successfully, it returns ACK to the
communications program on the PC. If the command fails or if a bad command is sent, the
Analyzer returns NAK.
The serial port should be set to the following:
Bits Per Second: 9600
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: Hardware
Configuring Printer Settings
You can change the way the Analyzer formats output sent to the printer.
1. Select the I/O tab.
2. Press the Printer button.
3. Press the Printer button and choose Seiko or Citizen. If no printer is attached to the
Analyzer, choose No Printer.
4. Set Header Frequency to First Page or All Pages to specify when a header will print. The
header includes basic information about the Analyzer, including the firmware version,
Analyzer serial number, and the current date.
