Configuring the Instrument for Computer Operations

Computer Operations 4

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.

PAR

E Odd

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.

ENTER

CtS

OFF

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.

Echo

OFF

ENTER Required

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.
