System Commands

SET PUMP NETWORK ADDRESS AND BAUD RATE

* ADR [ <address> [ B { 19200 | 9600 | 2400 | 1200 | 300 } ] ]
[DUAL | RECP]

Set/query pump network address

<address> => <n> [<n>]
<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

Query current address setting

*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

Getting Started With RS-232

Before beginning to develop pump control software for a computer, first setup and experiment with the
pump’s communication. After attaching the pump to the computer, run a terminal emulation Program on
the computer. A generic terminal emulator, supplied as standard software with many computers, can be
used to communicate with the pump in the Basic communications mode.
