Configuring the Instrument for Modem Operations

Modem Operations 6

Correct operation of the instrument RS-232/modem link depends on the baud rate, parity, CTS (Clear To Send), and Echo of the link parameters Perform the procedure in Figure 6-4 to establish the communication link parameters.

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 modem. 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 PC checks parity (if selected) and indicates when an error is detected. Select the parity then press

ENTER.
