PUMP CHAIN COMMANDS

The Pump Chain commands allow all pump control information to be managed from an external computer

source. These commands can also be used to control a series of pumps (up to 100) from a single computer

interface.

PHD Ultra commands are communicated to the pump via the RS-232 or USB port interfaces through a

terminal program such as HyperTerminal. In using the Pump Chain commands, you will need to assign

each pump in the pump chain a unique address, using the Set Pump Address command in the Settings

menu. The address range is from 00 to 99. This address value is used to identify which pump is to receive a

command and which pump is responding. Configure each pump with its assigned address and baud rate

s described in the Pump Settings section of this Guide.

Pump Chain Commands

The following instructions will help you to utilize the Pump Chain commands feature on the PHD ULTRA

™

pump.

Commands may be abbreviated to the first four letters, i.e. address would be abbreviated addr. A space

must follow the command if arguments are included.

If the pump address is nonzero, the one or two-digit pump address precedes the command and is separated

by a colon. For example, to set the infuse rate for pump 12, the command would look like “12:irat 3.2

ul/min”.

In the command list below, the following convention is used:

{ } A parameter (without the brackets)

[ ] Optional parameter

| Separator between parameter choices

- A range of values

The following prompts are returned after a command is executed:

: The pump is idle

> The pump is infusing

< The pump is withdrawing

* The pump stalled

T* The target was reached
