Remote Control via RS-232-C Interface
Setting the Transmission Parameters
To enable error-free and correct data transmission, the parameters of the instrument and the controller
should have the same setting. To prevent any problems during binary data transmission, the RS-232-C
interface should be set to 8 data bits, “No parity” and 1 stop bit. This data format corresponds to the
IEEE P1174 draft standard.
The baud rate and handshake can be manually changed in the Utilities - System - RS232 menu.
Call Utilities – System - RS232 menu.
Select desired baud rate and handshake.
Terminate input using the [1x/ENTER] key.

STATUS page is always displayed.
