1 In General
The FKG-1 is a compact crosshair generator. It is available as a printed circuit board designed
for O.E.M. costumers, or inside a small case. It generates a single crosshair and insert it into
a video signal. This video signal must be an externally connected video source. In most cases,
this will be a video camera. Figure 1 outlines a typical application.
All functions of the FKG-1 are controlled either by external potentiometers, or with PC con-
nected to the RS232/V.24. This allows the user the full adaption to his task. The configuration
is done by simple solder jumpers (printed circuit pads).

2.1 The Back Side Of The Case
The BAS / FBAS video signals can be connected to BNC connectors. For the usage of Y/C
video signals, SVHS connectors are used.
The serial interface of the FKG-1 is implemented as RS232 /V.24. The default baudrate is
9600[bps]. See Table 4 on page 8 for other configurations. The wiring is limited to three signals.
Only RxD, TxD and SG are used. All these signals are available at the 9-pole D-SUB connector.
The pinout of this connector is shown in table 1. It is designed for the use of standard 1:1 cable.
Table 1: Pinout of the D-Sub connector.

3 Connecting The Printed Circuit Board
The printed circuit board of the FKG-1 is a member of the FKG product family too. For this
variant, all the signals must be plugged into on-board connectors. Figure 3 shows the position
and the orientation of these connectors. The bevelled edge marks pin-1!
The following overview is a description of the available connectors. The names are equal to
figure 3. All the connectors below are screw clamp connectors1!
ST1 is a five-pole connector. The three potentiometers are connected here.
ST2 is a two-pole connector for the supply voltage.
ST3 is a four-pole connector. All three video types are connected here.
ST4 is a four-pole connector. This is the output of the video signal with the inserted crosshair.
ST5 is a four-pole connector for the RS232 / V.24 communication cable.

3.1 The Potentiometers
The default operation mode is the usage of potentiometers. It is important to use higher quality
potentiometers, because the cheaper ones could lead to a jittering crosshair! The dimension of
these devices must be between 4.7kΩand 10kΩ.
The pin assignment of ST1 and a sample wiring plan for the potentiometers is shown in
figure 4.

3.2 The Video Signals
The original video source must be connected to ST3. After the processing, the resulting video
signal is available at ST4. The whole signal path can process one of the signal forms BAS,
FBAS or Y/C. The signal form of the output is equal to the signal form of the connected video
source. In the case of BAS or FBAS, the component C (of Y/C) isn’t used neither at ST3 nor at
ST4. See Table 2 for the complete pin assignment of the both connectors.

3.3 The Serial Communication Port
The serial communication port of the FKG-1 is implemented as a RS232/V.24. The baud rate
(transmission speed) is adjustable. Only three signals are used for the communication. These
are the transmission signal TxD, the reception signal RxD and the signal ground. All of these
signals are connected to connector ST5. Table 3 shows the pin assignment.
Table 3: Pin assignment of ST5.
Pin Signal
1 transmission signal TxD
2 signal ground
3 reception signal RxD
3.4 The Supply Voltage
The supply voltage has to be connected to ST2. The FKG-1 needs a DC voltage between 8 V
and 12 V. The maximum current consumption is less then 80 mA. ST2 pin-1 is positive and pin-2
is ground.
3.5 Device Configuration
The configuration of the FKG-1 is done with eight solder jumpers. An opened jumper represents
the state Off, and a closed (shortened) jumper is equal to On.
The configuration comprises the width of the crosshairs, the communication speed and the
mode of operation. Details of the setup and the factory defaults are described in table 4.
Abinary value of two bits2allows the configuration of four different values assignable to the
line width. Table 5 shows all possible combinations and there meaning.

4 Operation Modes
4.1 Controlled by Potentiometers
This operation mode is only active, if the solder jumper J7 is not shortened. If you select this
mode, the crosshair and the brightness is controlled by three potentiometers. The Potentiometer
P1 controls the horizontal position, while P2 controls the vertical position. With P3, the level of
the brightness is adjustable in 255 steps. The value of white is hereby 0 Ω!
It isn’t necessary to save any data in this operation mode. All settings are controlled by
potentiometers or solder jumpers.
4.2 Controlled by RS232
As an alternative to the previously mentioned potentiometer mode, the serial mode gives the
user full control over all functions of the device. The communication protocol3is the same for
all members of the FKG family. This allows the usage of a common graphical front-end called
FKG-GUI. This program is available for Microsoft Windows (TM). The latest release of the
program is always available at our Internet homepage (see cover page).
This operation mode is only active, if the solder jumper J7 is shortened!
3The serial protocol is a ASCII based character oriented protocol. The documentation for this protocol is only
available in German. For more information call our support team.

User Manual FKG-1 5 Controlling the FKG-1 running Windows
5 Controlling the FKG-1 running Windows
Included in delivery of the FKG-1 is the Microsoft Windows executable FKG-GUI. This appli-
cations works with Windows-2000 and above.
5.1 Installation and application start
The applications simply consists of one executable and two DLL’s. There is no need for an
installation step. You are able to start the application directly from the CD-Rom. To use it from
the local harddisc, it is enough to copy the file into a directory of your choose.
FKG-GUI doesn’t write any data to your harddisc, nor does it write into the windows registry.
Important: In order to use the FKG-1 together with FKG-GUI, you have to configure
9600 bps! Ensure that the corresponding solder jumper is setup correctly.
5.2 Configuration of the application
After program start, the configuration dialog box as shown in figure 5 appears.
Figure 5: The configuration dialog.
Here you can select the serial port used for the FKG-1 connection. It is important, that the
device has been switched on.
Click the button “Test it!” to check your current selection. This test includes several steps.
First, the interface connection is established and configured. If the interface is already used by
another program, a mouse driver e.g., the error message shown in figure 6 appears.
In this case another serial port should be selected. The FKG-GUI is suitable for the use of up
to four interfaces. Since many usual PCs are provided with only two interfaces, a connection

may be requested for an serial port which is actually not available. In this case, the same error
message as shown in figure 6 will appear also.
The second step is performed, after the connection with the interface could be established.
This step is used to check the general communication function by sending a command to the
FKG-1 which requires an acknowledge for response. If this test fails, the error message shown
in figure 7 appears.
Figure 7: Error message, if communication fails.
This message means that the command has either not been received by the FKG-1 or that a
free interface has been identified but no device is connected. In this case you should check the
cable connection. If you are sure that the cable is OK and the connector is properly plugged,
repeat this test. If the same error message appears again, you should select another interface.
The last step is used to query the device ID of the FKG-1. Apart from the device name,
a dialog box as in figure 8 reports the version of the firmware and the maximum number of
supported crosshairs.
If this message box appears, the configuration procedure has been successfully completed.
Click the button “OK” to close the message box. While closing the configuration dialog box,
also by clicking the button “OK”, the program will query the current settings of the connected
FKG-1.
The main window shows the settings found. Figure 9 shows an example of such an initialized
main window.

Revision 1.5, Dipl.-Ing. Joerg Desch / esw 11 / 16

User Manual FKG-1 5 Controlling the FKG-1 running Windows
Note: Since the program is suitable for the use of up to four crosshairs, the buttons “Cross-2”
up to “Cross-4” for the FKG-1 always remain inactive.
5.3 Mode of operation
After program configuration, the main window is shown and active. This window is used for all
parameter settings. Each change will be transferred immediately to the FKG-1. For this reason,
the device must remain connected and activated.
The main window consists of three areas which are marked by 3D frames. The three window
areas are designated as follows:
•"‘Visible"’
•"‘Single Cross Settings"’
•"‘Common Camera Settings"’
Apart from these three areas, the main window includes the buttons "‘Exit"’ and “Configure..”.
Use the “Exit” button to close the program and the “Configure..” button if you wish to open the
configuration window again.
Note: When closing the program, the last crosshair selected will always be deselected.
5.3.1 The area “Visible”
This part of the window includes four buttons which are provided with LED symbols. These
buttons are used to activate or deactivate the individual crosshairs. The lit or unlit LEDs shows
the current status of the corresponding crosshair. If an LED is unlit, the crosshairs are not
activated, i.e. not visible. If the same button is clicked again, the crosshairs will become visible
again. This is also indicated by the green LED symbol in this button.
Invisible crosshairs can not be edited and the corresponding selection buttons are not active.
If the crosshair currently selected for modification shall be deactivated, the selection will be
revoked. In this case no crosshairs are selected.
5.3.2 The area “Single Cross Settings”
This area groups all elements which affect an individual crosshair. To modify it’s setup, a
crosshair must be selected by pressing the corresponding radio button inside the frame labeled
with “Select:”. The active selection is indicated by an red rhombus. Inside the FKG-1, the se-
lection is represented by changing the shading of the crosshair. To deselect the crosshair, simply
click the radio button again. Now none of the crosshairs will be selected.
Revision 1.5, Dipl.-Ing. Joerg Desch / esw 12 / 16

User Manual FKG-1 5 Controlling the FKG-1 running Windows
Note: The shading of the selected crosshairs diverge from the unselected crosshairs. If the shad-
ing of the unselected crosshairs (the normal display mode) is dark, than the selected crosshairs
are brighter. In the case of bright crosshairs, a darker shading is used to represent the selection.
Apart from the position functions, the line width and height can be changed. Using the counter
controls “Lineheight” and “Linewidth”, it is possible to select two different line heights and four
different line widths. Positioning is available through the arrow buttons. Each click on these
buttons will move the selected crosshair in the corresponding direction. The pitch of the move
can be set with the counter “Stepsize”. As default after the application start up, this value is set
to the smallest pitch.
The button labeled with a cross symbol is used to move the selected crosshairs to the middle
of the screen. With this function, you can quickly return to a basic position.
5.3.3 The area "‘Persistent Camera Settings"’
This area includes functions which affects the whole device, i.e. no crosshairs must have been
selected beforehand. With the slider “Brightness” you can set the general brightness of all
crosshairs displayed (normal operation mode). Changes are realized while the slider is moved,
so that all changes can be instantly monitored on the screen.
The buttons “Save”, “Recall” and “Reset” are of particular importance. With the “Save”
button you can save the current settings in the EEPROM of the FKG-1. These settings will then
be available next time, when the FKG-1 is powered on. No PC must be connected then.
The “Recall” button is used to undo all manual changes since the last program start or the last
saving process. This is effected by reading the values saved in the EEPROM, which are then
taken over as new settings. This might be advised, if the user has made unintended changes.
With the “Reset” button you can return to the factory setting as delivered. Because this proce-
dure will cause the deletion of all data stored in the EEPROM, the user will be asked if he really
wants to continue. Figure 10 shows the dialog box.
Figure 10: Confirmation of the reset demand.
The user now has got the option to run the reset or to cancel. Click “Yes” to confirm the
reset process. All available crosshairs will then be visible and grouped around the middle of the

picture. If you select “No”, the reset process will be cancelled without causing any data loss.
