9.2.5 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
Assuming that the current pumping rate units of all 3 pumps are currently mL/hr, send the following command,
followed by a carriage return , (spaces are optional):
0 rat 100 * 1 rat 250 * 2 rat 375 *
9.3 Command Errors and Alarms
If a command received by the pump is not recognized or the data is invalid, an error message will be in the
field of the response packet following the field. The following are the error responses:
=> ?
=>
λ Command is not recognized (‘?’ only)
NA Command is not currently applicable
