7.1.2 USB connector
A standard type A, USB connector is fitted to the MCU for copying logged data from the MCU to a
USB flash drive.
Inside the MCU all operational data is stored in the internal memory. This data can be copied to a
USB flash drive following the procedure as describe in section 7.2.1.3.
Per year and month a folder is created on the flash drive in which data files, containing the data per
day, are copied.
The data is stored as plain text and can be opened by any text editor or word processing application
on any computer for the purpose of viewing or printing.
7.1.3 Printer port
The print port can be used to connect a serial printer to the MCU.
The used printer must be compatible to the RS232 communication protocol. A printout of
operational data can be made at regular intervals.
A printout of the data can be made following the procedure as describe in section 7.2.1.3.
A printer is not provided by VAF Instruments.
Since all data is saved in the internal memory of the MCU and can by copied to a USB flash drive
there is no actual need for a printer. The printer port is only fitted to be used as an alternative to
copying the data to a USB flash drive.
7.1.4 Reset button
In the rare case the MCU is unresponsive; the reset button can be pushed with e.g. a paperclip to
forcibly reboot the MCU.
Previously stored data or setting will not be lost during a reboot.
7.1.5 Touch screen panel
The touch screen panel acts as the major interface between the MCU and the operator and displays
all relevant information.
The touch screen is of the resistive type. In order to activate a key on the screen, a small amount of
pressure has to be applied to the key by pressing it.
CAUTION:
IN ORDER NOT TO DAMAGE THE TOUCH SCREEN IT IS RECOMMENDED ONLY
TO PRESS THE TOUCH SCREEN BY YOUR FINGERS AND NOT BY ANY SHARP
OR POINTY OBJECT.
