Note:
All alphabetical characters must be sent in upper case format. The response may contain
lower case characters.
Every complete command message sent will receive a response - either a status code or
a data return. The nEXT pump can only process with one message at a time. It will only
accept a new message once the response to the previous message has been returned.
If the nEXT pump receives characters that are not framed inside start and stop
characters, it will ignore them. Messages with the stop character missing will be
discarded with no response when a new start character is received. If the nEXT pump
receives an unrecognisable message between the start and stop characters, it will return
an appropriate error message.
Refer to Multi-drop operation on page 52 for more information about operating the
nEXT pumps in multi-drop mode.
