10.2.5 Network Command Burst
The Network Command Burst feature is only applicable when communicating to a network of pumps.
This special feature allows commands to be sent to a network of pumps simultaneously. For example,
changing the pumping rates simultaneously on a network of pumps.
Note: Since this special feature violates the general communications protocol of one command-one
response, all of the pumps will be responding simultaneously, and therefore the communications response
to a Network Command Burst will be gibberish and should be ignored.
Command Format
Command Burst => *
Network Command Burst => < Command Burst > [Network Command Burst]
Where indicates the address of the pump that is to execute . Maximum address is 9.
n => {0 ... 9}
Example: Simultaneously change the pumping rates of 3 pumps on a pump network as follows:
Pump 0: 100 ml/hr
Pump 1: 250 ml/hr
Pump 2: 375 ml/hr
