Factory sengs The nEXT85 pump can be re-congured to its original factory sengs with
one serial command.
Assigning a mul-drop address Each individual pump must be programmed with its own mul-drop
address via a point-to-point connecon before introducon into a mul-

Message structure
The message structure and command set are the same for RS485 and RS232 opons. To
communicate a message to the nEXT85 pump, the characters must be sent in a specic order. If
the message does not conform to the correct structure it will be ignored and no reply will be
sent.
The correct structure to use is as follows:
• a valid start character, either a '!' character for a store operaon or a '?' character for a
query operaon, followed by
• a command, which will be an upper case alphabecal character, followed by
• an object number, comprising three decimal digits, followed by
• for some commands only, a data eld, comprising a sequence of characters separated
from the object number by a space, followed by
• a terminang carriage return
The message protocol in mul-drop mode is marginally dierent, refer to Mul-drop operaon
on page 99.
