[DUAL | RECP]
Set/query pump network address
=>Valid range: 0 to 99
B { 19200 | 9600 | 2400 | 1200 | 300 } will change the baud rate as indicated. NOTE: The command
response and all further communications will be at the specified baud rate.
DUAL Sets the pump to Dual Pumping mode with a secondary pump.
RECP
Sets the pump to Reciprocating Pumping mode with a secondary pump.
With both Dual and Reciprocating modes, the baud rate defaults to 19,200.
This is a special system command that will be accepted by the pump regardless of its current address. Once
set, the pump will only respond to commands with the set address and at the specified baud rate.
Note: Once DUAL or RECP is set, the pump will only respond to commands that are preceded by the ‘*’
character. To exit DUAL or RECP mode, reset the address: * ADR 0
Example: *ADR

*ADR 3
Set pump network address to 3. The pump will now only respond to
commands with address 3
*ADR 5 B 1200
Set the pump network address to 5 and the baud rate to 1200. The
command response will be at 1200 baud
