User Manual

65
The RS232 interface does not support flow control. The programmer should be
aware of this limitation and pay attention to the Instrument command process
time. If the remote commands are sent too fast the internal buffer may overrun
and cause communication errors. Therefore, it is mandatory to add a delay
between commands so that the Instrument has sufficient time to process.
13.7 Event_SW
The Event_SW output can be used to control external devices. The Instrument uses a
opto-coupler with an NPN transistor output.
