4.5 Electrical Connection Information
This section contains detailed information about the electrical connections of the various F/T system
components.
NOTICE:
Information in this section is intended for advanced users. Users whose systems
include an ATI-supplied DAQ card may skip this section.
The ATI DAQ F/T software features a modular design allowing for use with any data acquisition system
capable of electrically interfacing to the F/T System.
4.5.1 Signals and Power
CAUTION:
The analog signals output by the transducer do not map directly
into force and torque vectors. ATI DAQ F/T software with the calibration matrix
must be used to convert these values into force and torque data.

Reserved
This connection has an internal or future use. Do not use.
Note:
1. Power to the PS / IFPS box can be provided from either a 5 V source through the 26-Pin
connector or through the 12 V wall mounted power supply.
The PS and IFPS boxes include a 12 V wall mounted power supply. Power to the PS or IFPS box
can be provided through either the 12 V wall-mounted power supply or a 5 V source to the 26-Pin
connector. The PS box only requires one source; if both sources are connected, the PS box will use
the 12 V source and the 5 V source will be ignored.
Systems with an ATI-supplied DAQ card derive power from either the DAQ card or the 12 V wall
mounted power supply. If using a customer supplied DAQ card, a 12 V wall-mounted power supply
can be used, or a +5V and 0V power to the PS / IFPS box will need to be supplied. Without a PS
box, the user will need to VANA, AGnd , and -VANA power to the transducer. (Applicable
to 9105-TIF transducers only; 9105-TW transducers require an IFPS box.)
