Configuring the Instrument for Computer Operations
Correct operation of the interface between the instrument and PC depends on the baud
rate, parity, CTS (Clear To Send) and echo of the RS-232 interface parameters. Perform
the procedure in Figure 4-2 to establish these parameters for the instrument. The
instrument uses one stop bit, which is not selectable.

Selecting the bAUd (Baud) Rate. Press the
SHIFT key, release, and then press the LIST key
to open the communications parameters menu.
The baud rate sets the rate of data transfer
between the instrument and the PC. Normally,
the highest compatible rate is selected. Select
the rate using the up/down arrow keys, then
press ENTER.

the rate using the up/down arrow keys, then
press ENTER.
Selecting PAR (Parity). The 8th bit of a
character can be set to make all characters odd
(Odd) or even (E), or no parity at all (no). The
computer checks parity (if selected) and indicates
when an error is detected. Select the parity then
press ENTER.

computer checks parity (if selected) and indicates
when an error is detected. Select the parity then
press ENTER.
Selecting CtS (Clear To Send). The RS-232
CTS line (pin 8) is an input hardware control line
derived from the PC Request to Send (RTS) line.
When CTS is asserted, the instrument is allowed
to transmit data. If the PC RS-232 interface
does not have or use an RTS line, select OFF
then press ENTER.

Selecting Echo. When echo is On, each
character sent to the instrument is "echoed" back
to the PC. The applications software Starter
and Logger automatically turn echo OFF. The
primary use of Echo On is for operations with a
terminal emulator. Select the Echo parameter
then press ENTER.
