6.2.4 USB client interface for USB flash storage sticks (optional)
USB flash drives or memory sticks can be plugged in the USB-A socket of the control panel
located in the battery box, see also illustration 14.
Following points shall be recognized for a trouble free operation:
-
As long as a USB memory stick is plugged into the viasis control
panel no other data connection between the viasis and a computer,
particularly no USB host connection shall be established.
-
The USB interfaces of the control panel fulfills the USB 2.0 specifi-
cation. According a USB client interface need to deliver maximal 100
mA for „low power“ mass storage devices.
-
The USB memory stick shall only be plugged for the time of a data
transfer and be removed afterwards. As long as the USB memory
stick is plugged in the viasis does operate in measurement mode
After connection of a USB memory stick the viasis executes in sequence following tasks:
-
If not found in the USB stick root directory a folder “
VIASIS
” is created
-
Download of stored measurement data in a file (*.VTF) in the “VIASIS” folder. Stored
measurement data in the viasis are deleted afterwards.
-
If a firmware file
(*.BIN) is found in the “VIASIS” folder it is loaded and a firmware up-
date is started.
-
In case a parameter file (file extension *.PAR) is found in the “VIASIS” folder it is loaded
into the viasis and the viasis is reconfigured.
-
If not already created before a new the log file “USBINFO.TXT” is placed in the
“VIASIS” folder. All up- and download actions are logged herein.
A text entry example for writing a measurement data file in “USBINFO.TXT” follows:
Viasis 3003 - Version 4.12, 15SC4321
Date: 15.09.2015, Time: 14:14:46
Write SC_15SC4321_150915_001.VTF ok
Also if the viasis measurement data store is empty a file with the extension *.VTF will be cre-
ated. This file includes the current parameter and the event protocol of the viasis.

USB-Link
LED on the operator panel when using an USB memory stick
