5 ACU-TEST EVALUATION KIT
5.1 Evaluation Pack
FT can provide Acu-Test Evaluation Kits to assist FT742-SM users with connection, development and testing.
The kit connects the sensor to a power supply and a Windows PC using virtual COM ports. The USB test cables
convert either RS422 or RS485HD, the user should ensure the appropriate Acu-Test cable is connected:
•
The FT058 cable is for RS422 sensors
•
The FT059 cable is for RS485HD sensors
Figure 7: Acu-Test Cable
The Acu-Test Evaluation Kit includes a USB test cable and a CD. The CD contains the Acu-Vis 2.0 software and
user manuals. An external power supply capable of 6-30VDC and 2A is necessary, the FT062 power supply may
be used in locations unsuitable for a benchtop electronics power supply.
Note: The FT062 power supply requires a regional C13-style adaptor for mains connection. All connections should
be mated and operated in a dry and suitable working environment for electronics.

The Acu-Test kit allows the checking and modification of various settings, including a real-time wind data user
interface.
Acu-Vis 2.0 software will work on a computer running Microsoft Windows 7, 8, 8.1 and 10.
Note: RS485 half-duplex sensors running in Continuous Update (CU) mode can be difficult to
communicate with due to the limitations of half-duplex topology. Contact FT Technologies for assistance
or disable CU mode using Acu-Vis 2.0
Caution: Live connection/disconnection of the power and/or sensors during live operation, or miswiring
of the power leads could damage the equipment and is not covered by FT’s standard warranty terms
Warning: Modifying settings may alter the performance of FT wind sensors, ensure the user understands
the potential risks
Warning: Users should perform a risk assessment and be suitably trained before attempting to use any
electrical equipment. Personal injury may result from unsuitable working practices
