FREQUENTLY ASKED QUESTIONS
Q: Can I use the ONfinity system with other software?
A: The ONfinity system and FreeClass software allows your wand to work with any software on your computer. It acts basically like your mouse and will also provide the ability to annotate over other software as well as the ability to easily copy and paste screenshots into the FreeClass whiteboard pages.
Q: What size image can be interactive with the ONfinity system?
A: The ONfinity system's receiver will work at distances up to 17 feet. The receiver scans an area that is approximately two-thirds the width of the distance, therefore the maximum scan area is about 11.5 feet wide, which equates to a 14 foot diagonal image.
Q: Will the ONfinity receiver work with a rear projection screen?
A: Yes, the ONfinity receiver detects the light from the tip of the wand, therefore the fact that the rear projection screen allows light to pass through the screen makes this possible. In this setup application, the presenter can be in front of the screen while the projector and the ONfinity receiver are behind it.
Q: How can you judge if there is ambient lighting disturbance?
A: There is a red indication light on the top of the signal receiver. This indication light will be stable when there is no optical signal communicated from the E-Pen. When the receiver detects optical signals, it will flash. If there is no optical signal being transmitted from the E-Pen and the indication light keeps flashing, this means there is ambient lighting disturbance. In the case of positioning calibration failure, cursor fluctuating or unpredictable lines appearing, check the indication light on the signal receiver first. One simple way to find out the cause is to cover the front panel of the signal receiver with your hand. The indication light should stop flashing. This indicates the device is functioning properly and the signal reception failure is due to ambient disturbance. Otherwise, the device may be defective. Seek help with product distributor or reseller.
Q: How can I remove ambient lighting disturbance?
A: Avoid strong light shining directly on the projection screen or the signal receiver.
Disturbance from sunlight: Be aware that the disturbance of sunlight is not necessarily correlated to the brightness of the room. For example, when the drawn curtain leaves a slit which lets in a shaft of very bright sunlight it can cause very strong lighting disturbance for infra-red devices. Other sources of light can also cause disturbance to the signal receiver, such as lighting close to the projection screen or the signal receiver, and the existence of reflecting materials close to projection screen.
A: The Onfinity receiver has both a USB connection and a serial connection so in cases that require a cable that is longer than the USB cable, a serial cable can be connected to the ONfinity receiver and run to the computer. The ONfinity Serial/USB converter will then be needed to make the connection to the computer. See your ONfinity dealer for these cables.
Q: How long does the battery in the wand last?
A: The battery in the wand will last about a year with normal use. Replacement batteries are available at most drug stores, department stores or from your ONfinity dealer.
TIPS AND TRICKS
When using the ONfinity system with a projector setting atop a table, use Velcro to attach the receiver to the top of the projector. This will "lock" the positioning of the projector's image and the receiver's field of view, allowing the projector to be easily re-positioned or accidentally bumped without the need for re-calibration.
TROUBLE SHOOTING
I have received the error message “hardware device not found”
The reason for “hardware device not found” while the FreeClass program is being activated may be one of the following:
1. Connection cable is not connected properly.
Inspect the connection cable to make sure it is connected properly. Since the signal receiver is connected to the PC via a USB cable, when the PC is powered on, the ONfinity power indication light should be on as well. If not, check if the connection port between the equipment is proper and the connection cable is plugged in completely.
2. Some anti-virus software or programs may block the use of USB or serial port.
Make sure no such software or program is activated. If yes, close all such programs and restart the FreeClass program.
3. Defect on PC’s USB port.
Check if the PC’s USB port and the setting are functioning properly. Call a qualified engineer to repair in case of USB defect.
4. No USB driver has been installed.
After the installation of the USB driver on the PC, a new usable port can be found in “Control Panel – System –Device Manager-Port”. Otherwise, it is “driver not installed” or “not installed properly”. Alternatively, check “Control Panel-Device Manager-USB Controller”, if an unknown USB device found states that no driver has been installed or not installed properly, reinstall the USB drivers. These can be found on the system CD-Rom or on the support page of this website.
5. PC’s operating system recognizes the signal receiver as another device and activates the relevant program. This causes a serial port being occupied. Check if any unknown serial device has appeared in the Device Manager. For example if an abnormal serial device appears in “Control Panel-System-Device Manager-Mouse and other pointer device”, just prohibit the use of the device and restart the program again.
6. When the notebook PC’s power runs out, the USB port may stop functioning, causing the USB device not to be detected or utilized properly. In this case, the notebook PC should be connected to a power source. The USB port on some notebook PC’s may not supply the standard 500mA current or incompatible with the USB device. Under such unusual circumstances, please consult with PC engineer.
Remarks: the simple way to check device connection is to click at “About” on the tray menu. A hardware’s serial numbers HSN is listed in the menu window. The hardware may not be connected properly if it is not listed.
If the CM2 Max logo does not appear and 4 beeps are not heard after launching the FreeClass software, exit the software and try once again. In some cases the drivers are not functional until the software has opened a second time. We plan on fixing this situation in the near future.
No green dot appears on the PC screen after the positioning calibration routine has been activated.
This may be due to a number of reasons:
1. The PC screen is being refreshed continuously. Close all programs that involve screen refresh, e.g. Flash animations, etc.
2. The green dot will not appear when the signal receiver device is not detected by the PC. Check the device connection and restart the program.
The first green dot has not turned black in the process of positioning calibration.
First check if the indication light on the signal receiver is flashing continuously, if yes, that means the signal receiver is being disturbed by a light source. Try repositioning the receiver. Alternatively, it may be due to improper installation position of the signal receiver or the receiver is positioned too close to the screen.
The green dot has turned black automatically.
This may be due to ambient lighting disturbance. Adjust the position of the signal receiver or remove the lighting source. Also check that the pen is not active (button stuck on).
The E-Pen does not appear to be responding when in operation.
1. Check to see if the plastic shipping wrapper has been removed from the battery.
2. The E-Pen battery may need replacing.
3. Disturbance by strong ambient lighting.
4. Receiver is not connected properly.
5. The signal path from the signal receiver may be blocked by the user. Avoid blocking the signal path when working on the projection screen.
6. The receiver is not positioned correctly to "see" the image.
Calibration incomplete - the Wand does not turn all of the green dots black.
1. Reposition the receiver so that when the red button is pushed, the red dot appears in the center of the image.
2. If the red dot is in the center, the area scanned by the receiver may not be as large as the projected image. Zoom the image smaller with the projector zoom control or move the receiver further from the image.
The wand is not active at the very edge of the image.
1. The receiver may be repositioned to aim a bit more towards the edge that is not responding.
2. If the wand is not responding at both sides of the image, the area scanned by the receiver may not be as large as the projected image. Zoom the image smaller with the projector zoom control or move the receiver further from the image.
The annotation lines appear jagged in real-time writing.
1.The E-Pen is being used at a distance too far from the projection surface.
2. The E-Pen battery needs replacing.
The E-Pen does not function after the PC enters standby or sleep mode.
When the PC enters standby or sleep mode, the signal communication between the PC and the signal receiver is terminated. Quit the program and restart the program again to resume normal functionality.
The position of the mouse cursor is not accurate.
This can be due to the following:
1. Positioning calibration is not accurate.
2. The position of the signal receiver or the projector has been changed.
3. The screen display resolution has been changed. Re-calibration of the system is required.
4. If the projector has auto keystone correction, an adjustment to the image may cause the need for re-calibration.
NOTICES
Operation of the Optional ONfinity E-Pen
1. The (Optional) Stylus E-Pen functions in the same manner as the Pointer E-Pen (Wand) via its operational buttons, but can also be operated via its pen tip.
2. The Stylus E-Pen is pressure triggered and functions as mouse left click when pressed.
3. Hold the Stylus E-Pen at an angle of 30 to 45 degrees to the projection surface to implement annotation. Make sure the tip can be "seen" by the receiver.
4. The pen tip of the Stylus E-Pen is very delicate. Do not over press the pen tip when writing to avoid damage to the E-Pen or the projection surface.
5. In the case that the Stylus E-Pen lights up continuously while writing, slightly tap the pen tip with your hand to return it to its normal position.
The ONfinity E-Pen functions vial optical signals. It is important to make sure there is no strong light (e.g. sunlight) on the projection screen and the reception panel of the signal receiver when using the system.
Signal communication can be abnormal when the USB cable is too long. Use a serial cable and the ONfinity USB/Serial converter for cable distances beyond the distance accommodated by the provided USB cable(s). See your ONfinity dealer.
