1Requirements
For the subsequently installation of VISY-Density you need:
•VISY-Density (Part. No. 908560)
•Distance bushing
•FAFNIR USB Adapter (Part. No. 900040)
•Driver for FAFNIR USB Adapter
•Calibration Data of VISY-Density (comes with VISY-Density)
•Plastic safety ring (spare part)
•Circlip (spare part)
•Circlip pliers
•Hexagon Key for M4 grub screw (2 mm)
•Software “Hyperterminal”
VISY-Stick Advanced with a serial number lower than 38200 require
an firmware update to version 4.05. Please find the instructions in
the annex.
Make sure that the VI-4 board firmware is 4.06 or higher. To check
the firmware of the VI-4 board press the reset button (red push but-
ton) on the VI-4 board in the VISY-Command. The first three digits
that appear on the 7 segment display are showing the current firm-
ware (e.g. 4-0-8). If the firmware is below 4.06 please contact us for
the latest firmware version.
2Uninstall the VISY-Stick Advanced
Take the VISY-Stick Advanced carefully out of the tank. Write down the serial number
and the corresponding tank number of each VISY-Stick Advanced to ensure that you
are able to place the right VISY-Stick Advanced back into the right tank after VISY-
Density has been installed.

3Assemble VISY-Density
Figure 1: VISY-Stick Advanced with VISY-Density
Detach the circlip at the bottom end of
the VISY-Stick Advanced by using the
tong. Take off the safety ring and the
water floater.
Slide the distance bushing and then
VISY-Density on the VISY-Stick Ad-
vanced.
Make sure that VISY-Density is installed
with the laser printed side showing to
the top/sensor head.
If present slide the water float with the
marking “TOP” oriented towards the
sensor head onto the probe tube.
Reinstall the plastic safety ring and the
circlip.
Tighten both M4 grub screws on VISY-
Density with the hexagon key (2 mm).
Depending on the height in which VISY-
Density is tightened, the VISY-View or
VISY-SoftView will display the product
density as sump density (VISY-Density is
mounted at the end of the VISY-Stick
Advanced) or as density (VISY-Density is
mounted in a height of 200 mm.).
Slide the product float down onto the
distance bushing. Remove the 3 trans-
port locks of the VISY-Density.

4.1 Installing FAFNIR USB Adapter
Connect the FAFNIR USB Adapter to the USB-Port of your PC/Laptop. A window will
open telling you that a new hardware has been found.
For the FAFNIR USB Adapter you have to install the driver “FAFNIR USB
Adapter” and “FAFNIR USB Serial Adapter”.
Figure 2: Hardware Wizard Installation steps
•Select “No, not this time”
•Click on “Next>”

Page 4/12 Subsequent installation of VISY-Density
•Select “Install from a list or specific location (Advanced)”
•Click on “Next >”
•Select “Search for the best driver in these locations”
and choose the location of the drivers
•Click on “Next>”

Subsequent installation of VISY-Density Page 5/12
•Click on “Continue Anyway” and click on “Finish” when the installation of the
FAFNIR USB Serial Converter is done.
•A window opens asking you to install the FAFNIR USB Adapter.
•Repeat the previous steps before installing the driver for the FAFNIR USB
Adapter.
4.2 VISY-Density configuration
To configure VISY-Density you need the terminal program HyperTerminal. Hyper-
Terminal can be found on a Windows XP PC under: “Start” “Programs” 
“Accessories” “Communications” “HyperTerminal”.
If you are using another Windows version please search for a HyperTerminal version
online.
With VISY-Density you have received the calibration parameters. Please make sure
which VISY-Density module is mounted on which VISY-Stick Advanced before you
continue.
Connect the FAFNIR USB Adapter to the VISY-Stick Advanced.
Check under “Control Panel” “System” Tab “Hardware” “Devices” for the
ComPort of the “FAFNIR USB Adapter”.
Open the HyperTerminal and select the ComPort of the FAFNIR USB Adapter. Fill in a
suitable name (for example: density) under “Connection Description” and click on “OK”.
Fill in the communication settings for the ComPort 1200 bps 8N1 and click on “OK”.
Click on the button (looks like a telephone) shown in the picture below to disconnect.

Page 6/12 Subsequent installation of VISY-Density
•Click on the “Disconnect” button
•Open “File” “Properties” and select “Settings”
•Click on “ASCII Setup”
•Check “Send line ends with line feeds” and ”Echo typed characters locally”.
•Confirm both windows with “OK”
•Click on the phone “Connection” button to connect again.

Subsequent installation of VISY-Density Page 7/12
•Type “S␣␣␣␣0” (hit space four times between S and 0) and press <Enter>.
The VISY-Stick Advanced will send the serial number of the connected VISY-
Stick Advanced ( ␣= space).
Example:
There are two necessary steps to complete the configuration of VISY-Density.
(1) Type-in in HyperTerminal: RXP[Serial No. VISY-Stick Advanced]DS
(2) Type-in the DS Command (to be found on the table received with VISY-
Density) of the installed VISY-Density module behind the first part (see exam-
ple below)
Press <Enter> and the probe will answer with (i.O.). If the probe does not answer
please make sure that you have done each step correctly.
For example:
Disconnect the M12 connector
Serial Number of the Probe
Enter
manually
Copy from file

5Reinstall VISY-Stick Advanced
Before installation, pull out the 3 locking pins from the VISY-Density. Place the VISY-
Stick Advanced back in the tank. Make sure every VISY-Stick Advanced is in the right
tank.
6Set new “Product very low” Alarm
Read out the position of the product float with VISY-Setup (“Current Values” 
“Product level in mm” and “Real Filling Value”). Note down the information about the
floater position and make sure to set the “Product very low” alarm higher than that
position.
The product float has to be above VISY-Density.
7Appendix
7.1 Update the firmware of the VISY-Stick Advanced
Please contact [email protected] before updating the probes. We will be
sending you the current firmware and the necessary software.
Check under “Control Panel” “System” Tab “Hardware” “Devices” for the
ComPort of the “FAFNIR USB Adapter”.
Open the program HexLoad. Click on “Options” “Project…” and choose “Baudrate
57600” and the ComPort of the FAFNIR USB Adapter. Click on “File” “Open” and
select the current VISY-Stick Advanced firmware you received from us. Connect the
FAFNIR USB Adapter with the VISY-Stick Advanced. Choose “Target” “Auto” and
HexLoad will start updating the firmware.
If HexLoad shows nothing under “Target” take the M12 connector off and
reconnect.

7.2 Read out density information with VISY-SoftView
VISY-SoftView is a software which is running on our VISY-View Touch or on our VISY-
Command GUI. VISY-SoftView is able show the density data together with other tank
details. VISY-SoftView will be showing the density or the sump density depending on
the position in which VISY-Density is installed at the VISY-Stick Advanced.
In order to see the density with VISY-SoftView the function needs to be activated. To
activate go to “System Functions” “Configuration”. Enter the password “22765”.
Select the button “System Opt.” and then “Density”.
Press the button “Density values are visible” and save. VISY-SoftView will let you know
afterwards: “Currently: Density values are visible” (see below).

Page 10/12 Subsequent installation of VISY-Density
To see the density for one tank click on the desired tank and the following window will
open:
Figure 4: Tank Details

Subsequent installation of VISY-Density Page 11/12
7.3 Read out density information with VISY-Setup
Open VISY-Setup and connect with the VISY-Command by using the corresponding
ComPort. Go to “Current Values” and scroll down. You will be finding the “Product
Density” and the “Sump Density”. Depending on the position of VISY-Density you will
be seeing data in either one of those fields.
