Use this interface to set the RS232 parameters. Using RS232 requires you to use the Serial Interface, ISerial, built in the VISA COM libraries. Dim mgr As AgilentRMLib.SRMCls Dim instrument As VisaComLib.FormattedIO488 Set mgr = New AgilentRMLib.SRMCls Set instrument = New VisaComLib.FormattedIO488 Set instrument.IO = mgr.Open('ASRL1::INSTR') Notice how the interface family for RS232 is ASRL. First, connect to the instrument similarly to connecting to an instrument using GPIB, LAN or USB interfaces. Here is a table of typical parameter values: Parameter Typical Values Baud Rate 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 Parity / Data Bits None / 8 data bits, Even / 7 data bits, Odd / 7 data bits Handshake Mode None (no handshake mode), DTR/ DSR, Modem, RTS/ CTS, XON/ XOFF Number of Start Bits 1 bit Number of Stop Bits 1 bit, 2 bits You can write Visual Basic code that can set RS232 parameters for you. Refer to the instrument's documentation to determine settings for the following parameters.
