Edwards nEXT85 User Manual

If the nEXT85 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 nEXT85 pump receives an unrecognisable
message between the start and stop characters, it will return an appropriate error message.
Refer to Mul-drop operaon on page 99 for more informaon about operang the nEXT85
