* The RS232 interface does not have ow control mechanism. The programmer should be aware of
this limitation and notice the command process time of the power supply. If the remote commands
are sent too fast to the power supply, the internal buer may overrun and cause a communication
error. Therefore, a delay between commands to let the power supply have enough time to process
them is mandatory. All serial settings must match the settings congured on the PC in order for
communication to link successfully.
