There are a few basic aspects that may be the cause of the problems you've encountered. Please try each of the steps below. After each step, retry the interface to see if the difficulty has been resolved.
-
Make sure your radio is transmitting in the PPM mode and not PCM. For more information, please refer to the owner’s manual that accompanied the transmitter.
-
If you have a Futaba 9Z and a frequency synthesizer, please remove this synthesized module.
-
If you are using Windows 2000, you may have to install the drivers
manually.
-
If you are using Windows XP, you may have to install the drivers
manually.
-
If you are using the transmitter interface adapters pass through feature, please disconnect any other devices that are plugged into the transmitter interface adapter. This includes items such as a printer or scanner.
-
Ensure that your transmitter includes batteries and that the batteries are fully charged. If your transmitter did not "power up" automatically when the interface cord was inserted, turn the transmitter power "on" at this time. Additionally, make sure that your transmitter is in the FM or PPM mode.
-
Make sure that you are using the proper transmitter interface adapter cord for your particular transmitter. Also, confirm that the cord is properly and firmly inserted into the respective transmitter.
-
Remove the transmitter interface adapter from the parallel port. Re-attach the transmitter interface adapter to the parallel port using a screwdriver. Make sure that it is firmly secured to the port.
-
If using a transmitter which requires the use of the small adapter lead ( i.e. Futaba, Airtronics, Hitec, etc.) between the main transmitter interface adapter cord and the transmitter itself, unplug this small adapter lead from the main interface adapter cord. Then, firmly re-attach once again, listening for an audible "click" confirming that a proper connection is completed.
-
Remove the transmitter interface adapter cord from the back of the transmitter. If applicable, turn the transmitter power "off" and then "on" once again. Securely re-attach the interface adapter cord to the transmitter.
-
Make sure that the transmitter interface adapter is the selected method of control in the "Controller" tab. To do so, start the RealFlight program, click on the Simulator Settings button and then the Controller tab. RealFlight Transmitter Interface should be visible in the Controller Type indication. Additionally, ensure that your respective radio manufacturer is indicated in the Radio Mfr. dialog box. If not, modify the setting(s) accordingly. If the RealFlight Transmitter Interface is not listed as an option, reinstall RealFlight, and enter the interface serial # during the installation procedure.
-
Remove all items from the parallel port. If you have a printer, connect this to the parallel port and print a test page at this time. This will establish that the printer port is active.
-
Disconnect the printer from the parallel port, attaching the Transmitter Interface Adapter in its place. Plug the printer into the pass through on the interface and attempt to print a test page. If this does not work, your interface may not be securely attached. Remove the interface from the parallel port and re-attach it once again to the parallel port using a screwdriver to secure it firmly to the port.
-
Exit the RealFlight program at this time. Right click on the My Computer icon, click on the Properties box, then the Device Manager tab and uninstall all parallel port equipment (scanner, printer, etc) one item at a time. Reboot after each item is removed.
-
If you are comfortable working with the BIOS in your computer, reboot your computer and open your BIOS. Please contact your computer manufacturer if you have questions about accessing and changing your BIOS. Locate the LPT1 settings in the BIOS and change them accordingly. Try changing its mode setting to: (1) ECP; (2) EPP; (3) BiDirectional. Test the interface after each change.
Please note that after you try each suggestion, you must recalibrate the controller to test whether the problem has been resolved.
Following the steps above should have your transmitter interface adapter functioning properly. If not, we suggest that you try your interface on a friend's computer if possible. Alternately, you might also attempt to test another brand and/or transmitter model on your computer as well.
