5.6 COMMUNICATION PROTOCOL
5.6.1 General Information
5.6.2 Accessing a ZUP Unit
5.6.3 End of Message
The average command processing time of the ZUP Series is 15mSec. It is not recommended to send
strings of commands to the ZUP power supply without considering the processing time.
For query commands ( ? , ! ) , wait until the ZUP reply message has been completed , before sending a
new command.
The default condition of the ZUP series is Listen mode. In order to access a ZUP unit, for sending a
command or query, the address of that unit should be sent by the host controller (:ADRn;). The ZUP that
recognizes it’s address becomes active and can communicate with the host controller. The other units
remain in Listen mode, waiting to receive their address. To access another unit, the controller should
send the address of that unit. The previously active unit changes it’s state to Listen mode and the
addressed unit becomes active.
The messages generated by the ZUP are terminated by an end of message:
< CR > carriage return character
< LF > line feed character
When sending a message to the ZUP, there is no need for the end of message characters.
