•
•
The factory selected baud rate is 9600.
When you choose a baud rate, make sure the programming computer that you
are connecting to the SourceMeter can support the baud rate you selected. Both
the SourceMeter and the other device must be configured for the same baud rate.
Data bits and parity
The RS-232 interface can be configured to send/receive data that is 7 or 8 bits
long using even, odd, or no parity. No parity is only valid when using 8 data bits.
Flow control (signal handshaking)
Signal handshaking between the controller and the instrument allows the two
devices to communicate to each other regarding being ready or not ready to
receive data.
The RS-232 interface provides two control lines (RTS and CTS) for this purpose
(see
data, it will transmit when it receives the clear to send (CTS) signal from the
