Setting the Flow Control
The flow control parameter applies only to RS-232 communication. This
parameter determines the type of serial communication used.
Choose Soft if you want the speed of data transmission to match the speed
at which the device can process it. This enables the computer and the
CD/PMD Analyzer Source to stop each other from transmitting by sending a
control character (Xoff). They will also be able to restart the transmission
by sending another control character (Xon). This is known as a software
handshake, a procedure requiring a special cable.
To set a flow control:
1. Press the Setup key.
2. Use the up/down or left/right arrow keys to select Flow Ctrl. The
current setting is displayed.
3. Press ENTER, then use the up/down arrow keys to select the type of
flow you want. None means no flow control. Soft allows the unit or
computer controlling it, to turn the data transmission on or off.
4. Press ENTER to confirm.
