AKD5602A Datasheet, PDF (2/24 Pages) Asahi Kasei Microsystems – Evaluation board for AK5602A

[AKD5602A]
< Hardware operating conditions >
(1) Power supply to the evaluation board
There need two powers in the evaluation board. The one is for measuring block, AK5602A and the other is for IF
block to a PC. The power plane and ground plane of measuring block and IF block to PC are separated by photo
couplers on the evaluation board.
This separation is needed to prevent from causing possible damage to PC.
Output power1 (DC: 3V or 5V) for AK5602A and output power2 (DC: 3V or 5V) for IF block to the PC should be
connected to the power supply block of AK5602A evaluation board respectively.
When AC signal more than 100V is used as the voltage inputs to the evaluation board, AC source of output
power1 and output power2 may be separated to prevent from causing possible damage to the PC.
(2) The interface to voltage signal input and current signal input
Voltage signal input: direct input intended for AC voltage such as 115 V power line or BNC input for signal
oscillator.
Current signal input: direct input intended for AC current signal at secondary side of Current Transformer or BNC
input for signal oscillator. Load resistors of CT on the board should be selected in the direct input connection.
The electrical interface of voltage input and current input of AK5602A is differential.
< Software operating conditions >
OS: Windows 2000 or XP
Screen size: 1024 X 768
USB port: 1 channel
3. Installation of software drivers, the system startup and the exit
3 - 1. Installation of USB drivers (needed to execute only once)
(1) Connect a USB cable between a PC and the evaluation board after DC power being applied to the evaluation
board.
(2) If a message, “new hardware is detected” appears on the screen, install AK5602USB.inf file.
(3) If the USB driver will have been installed successfully, the assigned communication port number will be
displayed at AK5602 EVABOARD Serial Port Driver of COM and LPT of Device Manager. This port number
must be selected when the software of the AK5602A system is started.
3 - 2.Start up (Normal operation)
(1) Feed the power (+3V or +5V) the AK5602A evaluation board.
(2) Connect a USB cable between the evaluation board and the PC.
(3) Boot the software of AK_EvaTool_Eng.exe
3 - 3.Exit
(1) Exit the program of the evaluation board system.
(2) Pull out the USB cable from the evaluation board.
(3) Pull out the power cables from the evaluation board.
3 - 4.Others
Countermeasures against abnormal conditions
When the evaluation board enters in a halt state, try the start up sequence again after conducting the exit
sequence written above.
