1. Introduction The PQ3-P is a special version of a Drivedata product known as the PQ3 or “µFourSight”. The PQ3-P version utilises high quality professional Hirose connectors to allow secure and reliable connection to the Drivedata range of cameras and flashcard recorders. µFourSight is essentially the main control board inside the PQ3 and PQ3-P. This manual and the optional PC Configuration utility will generally refer to “µFourSight” rather than “PQ3” or “PQ3-P”. The Hirose connector pinouts are detailed in the specifications if you need to make your own input/output cables.

For ease of use, the system includes 16 pre-set display modes accessible via an external hex switch, any of which may be reconfigured via the serial Port using the optional PC Configuration utility & cable. The system provides excellent picture quality coupled with a real-time update rate per channel. Custom display modes can also be configured using the PC Configuration utility, allowing the user to optimise the µFourSight output.

µFourSight will operate with almost any composite analogue video source, automatically configuring itself for PAL or NTSC operation. µFourSight consists of a small DC powered unit that is ideal for system integrators, covert and mobile installations.

For OEM applications, the system may be supplied as a unit or PCB, together with full support for interfacing to the product’s serial control protocol.

Figure 1: µFourSight Application Diagram.

2. Quick Start Guide The following describes the basic installation:

2.1 Connect the video output of the µFourSight to a video monitor. The output video format will be the same as the first valid video input 10 seconds after a video source is detected. If no video is detected on power up, NTSC is used until a valid source is present at which point the 10 seconds counter is started.

2.2 Connect up to 4 video sources (cameras) to the µFourSight’s video inputs. µFourSight operates with either PAL or NTSC video formats. All video connections are nominally 1 V pp with fixed 75-ohm terminations.

2.3 Connect a 5 to 28 V DC power source to the DC input. As a guide, µFourSight requires approximately 140 mA at 12 Volts DC.

2.4 Any of the 16 Factory Default Output modes (see Section 5: Factory Default Output Modes) can be selected by using the Hex Switch on the front panel.

3. LED Indicator The bicolour LED indicator located on the front panel shows the status of the µFourSight system with a repeating series of 5 flashes followed by a gap. The first flash indicates the status of input 1 (green for PAL, red for NTSC and green/red for no valid input) and the second, third and fourth flashes indicate the status in turn of channels 2, 3 and 4. The fifth flash indicates whether the output video standard is PAL (green) or NTSC (red).

4. Factory Default Output Modes The hex switch on the front panel selects one of µFourSight’s 16 default picture-in-picture modes. You may select, edit and save these settings to your own requirements via, either the Serial Port using the µFourSight PC application software, or by using the four individual switches (see Section 7: Programming Without A Serial Port). The factory set default modes are as follows: N.B Channel 4 is usually configured with mirroring enabled

Figure 2: Factory Default Output Modes.

5. Operation with other equipment The video output from the µFourSight system will be either PAL or NTSC standard. µFourSight can therefore be used to transmit up to four video channels (as a single picture) over any video transmission system including Analogue Video Links, Digital Video Links as well as ISDN, PTN, GSM and Ethernet video codecs providing they accept a composite video input (see Figure 3). Please note that no vertical blanking data is preserved from the incoming video streams.

Figure 3: Configuration with Video Links

NOTE: When uFourSight is in video standard auto detect mode, if a change in output video standard is required then the unit will reset and select the new video standard. Some cameras will switch standard several times when first powered up, analogue and digital links may also switch video standards when they have a poor link. Selecting a manual video standard will alleviate these problems. Please contact Drivedata for information on how to set the video standard manually on your unit if you need to do this.

6. Serial command interface Using the optional serial cable connected to an IBM-PC serial port; users can configure the µFourSight system. This provides the ability for the user to re-configure various operating parameters, storing the final result as a preset. The serial port uses 8 Data bit, 1 Stop bit, no Parity, 38400 Baud.

7. RS232 command protocol The serial commands are issued as ASCII characters followed, if required, by a hex number in ASCII format. Each command data sequence is terminated by Carriage Return Line Feed (CRLF). Unrecognised commands are ignored. All user commands are echoed.

indicate an ASCII hex number

NOTE - Values written to the µFourSight system modify volatile memory locations. In order for the values to be available after the next power down, the STORE PRESET command must be issued.

8. Optional PC Application Software

8.1 Installation The application software allows full control of µFourSight. Presets can be defined easy and quickly, saved and recalled from the PC, transferred to and from a connected µFourSight. Customer upgrade of the µFourSight is also catered for.

8.2 Software installation The PC Configuration software is designed to operate with a PC running Windows 9x or higher. A free RS232 (serial com) port is also required. Some PCs are no longer supplied with dedicated RS232 serial ports. In this case a USB to serial adapter should be used. If in doubt, please contact Drivedata.

Insert the µFourSight CD ROM into a CD ROM drive on the PC. The installation should auto-run. If it doesn’t then activate Start>Run>CDROM:\”SetUp.exe”. The Default installation folder is C:\Ovation\uFourSight. Please note: For your convenience, Install will place a shortcut to ‘uFS.exe’ onto the PC Desktop.

8.3 Uninstalling the µFourSight Software As the µFourSight software registers itself with Windows®, it should be uninstalled by using the ‘Add or Remove Programs’ utility in the Windows® ‘Control Panel’ folder.

8.4 Hardware Set-Up With the serial lead provided connect the PC to the µFourSight and apply power (5 to 28V) from a PSU capable of providing at least 2W.

8.5 Software Initialisation 8.5.1 Run the software by double clicking on the ‘uFS’ Desktop shortcut. The main

control screen should be displayed.

Figure 9: µFourSight Main Screen

8.5.2 Connect video and power to the system.

8.5.3 The communication window shows all commands sent from the PC (in green) and all replies received from the µFourSight (in yellow). Advanced users can enter commands directly into this window – full details can be found in sections 8 and 9. You must ‘click’ inside this window for it to become active.

8.5.4 If the µFourSight unit is communicating with the PC then, when µFourSight first powers up, the following text should be displayed in the Communication

Window stating the µFourSight’s current firmware issue. Figure 10: Communication Window

8.5.5 You can make or break communication with µFourSight by toggling the

Connect / Disconnect button along the bottom toolbar. Figure 11: Connect /Disconnect Button Plus COM Port Button

If there is no communication then it may be necessary to change the Com Port setting. This is done by selecting a different COM Port in the drop down window at the bottom left of the screen

N.B.: If at any time, you wish to check that µFourSight and the PC are communicating, simply click in the communication window and press the ‘Return’ key on the PC. The µFourSight should reply with a ‘>’.

Figure 12: ‘>’ Reply From µFourSight.

Reminder: All communication sent to µFourSight is shown in green. All communication received from µFourSight is shown in yellow.

8.6 Basic Principles 8.6.1 Selecting the display mode, Left Clicking with the mouse, and then placing the display mode into a preset, by again Left Clicking the mouse, accomplish assigning a preset.

Figure 13: Creating A Preset

8.6.2 Once the display mode is assigned to a preset, the primary channel can be selected by Left Clicking on the primary section of the graphic. If the display mode uses only two channels, Left Clicking changes the channel to display in that section of the screen. Only the Quad and custom display modes are fixed.

Figure 14: The Image Window

8.6.3 Right Clicking a preset forces µFourSight to display the chosen preset. If the preset is blank, then the preset is first read back from µFourSight. It should be noted that at this point no changes have been made to the stored presets in µFourSight. The PC software is sending the ‘Select Mode’ instruction direct to µFourSight.

8.6.4Once any changes have been made, but not yet written to µFourSight, the ‘Write button will flash to remind the user. Pressing the ‘Write’ button will transfer preset information for any preset that is not blank.

Figure 15: Preset Control Buttons.

8.6.4 Pressing the ‘Read’ button transfers the preset data stored in µFourSight to the PC. Pressing the ‘Save’ button allows a user to save the presets to the PC.

Figure 16: Save Presets

Once the presets have been saved to the PC, they can be loaded back in at any time using the ‘Load’ button. Pressing the ‘Write’ button will transfer the presets to µFourSight. Thus a number of units can easily be given the same set of presets.

8.6.5 Pressing the ‘H’ or ‘V’ buttons associated with each camera input, toggles the horizontal and vertical mirror functions. The corresponding button is highlighted if the mirror function is active.

Figure 17: Mirror Controls

8.6.6 User OSD text for each camera input is entered into the edit box using up to

eight alpha, numeric characters. Any camera which has no text assigned displays the channel number. The OSD text is stored in non-volatile memory

so only needs to be entered once. Figure 18: User OSD Text

8.6.7 Factory default presets can be reloaded at any time by typing ‘default’ followed by CR in the terminal window. µFourSight will reset the presets to factory default settings; turn off all mirror functions, erasing user OSD text and

then reset. Custom display modes are not affected. Figure 19: Reloading Factor Default Presets

8.7 Custom Display Modes 8.7.1 Users that require a display mode not already catered for can create their

own. Up to eight custom display modes can be created and then assigned to a preset. Right clicking on the required custom display mode opens the edit window.

Figure 20: Custom Display Mode.

8.7.2 To setup a display mode it is advised to have the appropriate number of inputs and a display with similar characteristics to the intended setup. Most LCD monitors display nearly all the active video where as CRT monitors, unless they have an under scan function will severely reduce the viewable area. The dotted line on the display window indicates the typical viewable area on a CRT display.

8.7.3 Select a channel to edit, turn it on or off as required then select PIP mode if

the channel needs to be forced to the forefront and boundary if a two pixel wide border is required.

8.7.4 Follow the on screen instructions to create the display mode. 8.7.5 Pressing the Close button transfers the data to the main program so that it

can be transferred to the µFourSight and/or PC as a custom display mode. If the Abort button is pressed, all data entered is ignored.

9. Fault Finding

• If the µFourSight appears not to be functioning correctly it is advisable to check the following:

• If the LED does not light, check that the µFourSight system is connected to a suitable power supply (5 to 28 Volts dc, 2.5 Watts) with the correct polarity.

• If the LED is flashing, check that each video input is recognised by the µFourSight (LED flashes red or green - see Section 0) – if not then check the appropriate video input.

• Check that the output is the expected PAL/NTSC by observing the LED – If it is not as required then try a power cycle. If there is still a problem the internal DIP switches may be incorrectly set so please contact Drivedata.

• If there is a problem with communicating via the RS232C port, then please refer to Section 6 and 7.

• You can also refer to the support section of our website: www.drivedata.com

and the FAQs in the PQ3, PQ3-P or µFourSight product pages for common issues and resolutions.
