Under connection settings switch off the "beam" - apparently there is a conflict between the IR beam port and one of the ports used by the GPS system. Has worked for me.

Communication port is not working properly

COM1 and COM2 refer to a computer's communications, or serial, ports. COM1 ports are often used on older PCs to connect network devices, digital cameras and mice. Faulty drivers software that enables the hardware to communicate with the operating system or incorrect hardware configuration can influence COM1 behavior. In rare cases, the expansion card that adds the serial ports to the PC can fail, rendering both COM1 and COM2 ports useless. To repair a COM1 port, you must determine what is preventing the port from working before attempting a solution.

Click "Start." Go to "Control Panel" and then click "Hardware & Sound." Select "Device Manager" from the submenu. Expand "Ports (COM & LPT)." Double-click "COM1." Review Device Status on the General tab to check for problems with the software driver. If the message "The Device Is Working Properly" appears, click "OK" to close the window; otherwise, look up the error message on Microsoft Support. Follow the directions in the Knowledge Base to correct the issue. Press "Alt" and "V" to open View. Scroll to "Resources by Type." Press "Enter." Double-click "Interrupt Request (IRQ)" to see a list of devices. Double-click "Communications Port (COM1)." Check the term to the left of COM1 to see if the card uses an ISA or PCI interface. If the card uses a PCI interface, it can use the same IRQ as another PCI device without producing a hardware conflict. If the device is ISA, it needs its own IRQ. Go to the "Resources" tab. If "No Conflicts" appears in the Conflicting Device List, close the window; otherwise, uncheck "Use Automatic Settings." Click the drop-down menu and select each configuration until the port no longer interferes with another device. If conflicts occur with each configuration, double-click "IRQ"; you may need to try different configurations before Windows gives you permission to edit the interrupt request. Click the up or down arrow to change the IRQ until the message "No Devices Are Conflicting" appears in the Conflict Information field. Click "OK" to close each window. Click "Yes" when prompted. Connect a device to the COM1 port to test the port. If the device doesn't respond, shut down the computer and then unplug the power cable. Disconnect all devices from the back of the PC. Remove the case cover and touch the computer's chassis. Set the computer on its side so that the PCI and ISA cards sit at a 90-degree angle to the floor. Find the serial ports on the back of the PC. Look on the opposite side of the case to find the associated card. Shine a flashlight onto the card and make sure that the copper contacts are not visible. If you can see the contacts, reseat the card in its slot so that it's fully installed to the motherboard. Reassemble the case and boot into Windows to test the COM1 port. If the port still fails to work, you may need to replace the serial port card.

I have a Cipherlab scanner 8001, when i connect it to a linux computer, it doesnt download it gives me a Time out error, but when i connect a Cipher scanner 711 to the same COM port it works. Please advice...

OK,you indicated COM1 serial port is working on the a Cipher scanner 711.
Please check the communication setting on the Cipher scanner 711.
The most popular setting are
9600 bps 8 bits N for no parity check and 1 for check bit.
Short for as
9600 8 N 1
Check the setting on the Cipher scanner 711 communication speed and make set the Cipherlab scanner 8001 to the same rate.
MAKE SURE YOU RE-BOOT the Cipherlab scanner 8001 before re-try.

Please keep me up to date on the fix via email.

No valid GPS signal for two days, what I can do?

You can try a reset Check in the manual where the reset hole is i thinlk this model is under the scfreen surround which is removable.

This will take ut back to factory settings, you might want to check if its set to the right PORT and BAUD try this

GPS Program Port: COM1
GPS Hardware Port: COM9
Baud Rate: 4880
Manage GPS Automatically (Ticked)

Now other reasons are low battery= low signal//fully charge the battery

no signal from satellites= damaged SIIRF chip caused by plugging into car power when starting engine...needs new m/board

Maximum time to access 1-9 minutes max...

Please rate my help++++Thanks for using FIXYA...

Hello! I have a problem with scanning bar codes by ls2208 scanner. This device uses rs232 serial port, and when I try to read some bar code, the scanner is reading, but there is no number in notepad. How...


The scanner is sending the data to the serial port. You need an application to pull that data in off of the COM port. You can test using HyperTerminal. The scanner defaults to 9600 baud, 8 data bits, 1 stop bit, no parity and no hardware or software handshaking. Point HyperTerminal to the correct COM port (most likely COM1) and set it to the settings I just listed. When you scan you should see the data show up in the window.

If you want the data to go into Notepad or any other program expecting keyboard strokes I would recommend the Motorola (formerly Symbol) USB cable CBA-U01-S07ZAR or the CBA-K01-S07PAR keyboard wedge cable.

Garmin GPS III Pilot to PC communication problem

If it were doing this just on the Vista machine I would say it was Vista related but since you are getting it from an xp machine as well the problem is either cable or the gps unit. You don;t say if this just started happening or ? If you can try out the cable on something else to make sure so you can eliminate it. About the only thing you can do is to make sure the port settings in the pilot are set correctly. Generally the slower the better if you are having communication problems as this makes the signal timing not as critical. Try 9600 baud to start. Make sure that the data bits are also set roght. This is the 8n1 or 7n1 thing you see. I can;t think of what the default is on the garmin but as long as both pc and garmin have speed, bits, parity, and stop but set the same they should talk.

Try to download from the unit as well as upload.Unfortunetly you can only change the speed and protocal or reset the unit. You won't be able to fix it if is a hardware thing. If you are using a USB to Serial adapter then I would say that is your problem or could be. Cheaper ones just don't work often on higher port speeds. You might want to try the gps on a pc with a actual serial port if you are using one. If it works then you should try a different brand of adapter or really slow down the speeds.

This won;t solve it unless you luck out but it should let you know where the problem is.

NMEA communication does not work ( but file transfer is OK)

Try rebooting windows, with gps off connect the cable to gps.

Go out side get a good gps signals on nav menu.

Set the gps communications menu to , nmea, 2.1

Plug the device into a good usb port.

If you look under modems, in control panel you should see a new modem called explorist xxx

If you look at the properties for that you can see its com port number.

I just tried this program

and it views nmea from the explorist, just set the com port to the one in the explorist modem .
