drop mode. The address number 99 is reserved as a wild card and is used in
the query set up detailed later.
The reply will be as follows:
Reply * S 8 5 0 sp r cr
The multi
‑
drop address is stored in the pump.
To check if the pump has a multi-drop address, send the command that follows:
Command ? S 8 5 0 cr
If the reply is as follows, the pump has multi

Reply = S 8 5 0 sp 0 cr
If the pump has a multi-drop address, there will be no reply. Communicate with the
pump in multi-drop message protocol. Refer to Multi-drop operation on page 56 for
more information about multi-drop mode and multi-drop message protocol.
To check the multi-drop address of the pump, send the query as follows (using wild card
address 99 which means 'any' node):
Command # 9 9 : 9 9 ? S 8 5 0 cr
The reply will be as follows, where dd shows the multi-drop address of the pump:
Reply # 9 9 : 9 9 = S 8 5 0 sp d d cr
Multi-drop mode can be disabled by assigning the pump an address 0. To do this, send
the command that follows (where dd shows the multi-drop address of the pump. XX
shows the address of the node that is sending the command):
Command # d d : x x 1 S 8 5 0 sp 0 cr
The reply will be as follows:
Reply # x x : d d * S 8 5 0 sp 0 cr
When the multi-drop mode is disabled, the pump will not respond to multi-drop
commands.
