Transducer Interface Setup
Select a Zero Method
Before you install a transducer and zero it, you must configure the transducer
interface (TI) for the appropriate operating mode.
Equipment required
You will need:
• A laptop computer (at test track) or desktop PC with Window 2000 or XP
operating system.
• A USB 2.0 communication cable with type A to type B connectors.
• SWIFT Transducer Interface Utilities diskette.
• Some experience with DOS commands and text editors.
Modes
There are two separate modes for using the transducer interface. The mode you
choose depends on whether you will use the transducer in a spinning (test track)
application (AngleMode = 0) or non-spinning (road simulator) application
(AngleMode = 1).
If you are using the same transducer with a road simulator that you used
previously on the test track, or vice versa you must download the proper
calibration file and re-zero the transducer.
In either mode, the zero button on the front panel of the TI is used to zero the
angle and balance the bridges.
What you need to do
To change the angle mode used by the TI:
1. Copy the original calibration file from the CD or diskette that came with the
transducer to the computer.
Note A separate calibration file was created at the factory for each transducer.
In the next steps, note the serial number of the transducer identified in
the calibration file and the serial number of the TI box that the file was
downloaded to. This information will be used later.
2. Edit the calibration file to select appropriate angle mode: 0 = spinning,
1 = non-spinning (fixed).
3. Download the modified calibration file from the computer to the TI box.
4. Repeat the process for all of the transducers.
These steps are described in detail in the following sections.
