It is not recommended to sendstrings 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 anew command.The default condition of the ZUP series is Listen mode. In order to access a ZUP unit, for sending acommand or query, the address of that unit should be sent by the host controller (:ADRn;). The ZUP thatrecognizes it’s address becomes active and can communicate with the host controller. The other unitsremain in Listen mode, waiting to receive their address. To access another unit, the controller shouldsend the address of that unit. The previously active unit changes it’s state to Listen mode and theaddressed unit becomes active.The messages generated by the ZUP are terminated by an end of message:< CR > carriage return character< LF > line feed characterWhen sending a message to the ZUP, there is no need for the end of message characters.
