After setting up the Doppler String Phantom, turn on the power switch (located on the back of the controller).
The display reads
UP=H2O DOWN=H2O/GLYCOL
.
1. If the tank is filled with water, press
UP
. If the tank is filled with velocity-corrected fluid, press
DOWN
.
(See About Velocity-Corrected Fluid on page 4 for more information.)
The display reads
SELECT A FUNCTION
.
2. Press
TEST
or
PHYSIOLOGICAL
to select a waveform group.
The display shows a waveform.
3. Press
UP
or
DOWN
to select a waveform. (See Appendix A for graphs of waveforms.)
4. Press
EXECUTE
to start the motor.
5. To select a different waveform, you may press
UP
or
DOWN
at any time while the motor is running.
6. To reverse the direction of simulated flow, press
FLOW REV
at any time.
An arrow in the bottom right corner of the display indicates the flow direction.
7. To change functions (for example, to switch from physiological waveforms to constant speeds), press
ESCAPE
. The display reads

RS-232 INSTRUCTIONS
Introduction
The remote control software allows all of the same functions that are available from the front panel. It is primarily
a serial communications feature for use with automatic testing equipment, but may be used by anyone wanting
to control the phantom for standardized testing. It may be controlled by a laptop, desktop, or a process control
computer.
To establish the link between the Doppler String Phantom controller and your computer, any common RS-232
communications program such as Pro-Comm Plus, Teraterm Plus, Microsoft Hyperterminal, etc., may be used.
The communications program must be set to 9600, N, 8, 1. Use hardware flow control. If your computer does
not have an RS-232 port, you can use an adapter available locally that will convert a standard USB port to RS-
232.
Getting Started
To begin using the remote control feature:
1. Ensure the Doppler String Phantom controller is powered off (rear panel switch).
2. Plug the power cable into the
AC Receptacle
and into an AC power source. The label on the AC
Receptacle indicates 120 volts. If using with 220 volts, use step down controller (Model 901-C, sold sepa-
rately).
3. Plug the custom RS-232 cord (supplied with the Doppler String Phantom) into the
RS-232
receptacle
on the back of the controller.
4. Plug the motor cable into the
Drive Motor
receptacle on the back of the controller.
5. Start the communications program.
6. Turn on the power on the controller (rear panel switch).
