Transducer Interface
SWIFT 40 Sensors Hardware Overview 33
The angle output for a tire rotating at constant velocity can be represented by the
following illustration:
Although you may not routinely use it, the angle output information is available
for tasks such as tire uniformity testing and troubleshooting. You may also
calculate angular velocity by measuring the frequency of the angle output signal.
Communications
The TI provides a serial port for remote communication. The port allows
connection to an RS-232 or RS-485 host for multidrop communication. This
interface is compatible with the MTS 407 Controller protocol, and 407
Controllers may also be in the same multidrop communication chain. A
multidrop configuration can include up to 32 total devices in any combination,
with a maximum of nine TIs (limited to addresses 1 through 9).
The serial interface provides the following capabilities:
• allows the user to save and restore TI setup parameters.
• is compatible with LabVIEW®.
• is compatible with serial port-equipped computers (UNIX machines,
Macintosh, and IBM PC).
• is able to link multiple TIs (and 407 Controllers) to one host computer.
