Gold Member Username: LklivesPost Number: 8219 Registered: Jan-06 | MOST FTA receivers are made for computers with SERIAL ports, NOT USB ports...this has been addressed for years here and common knowledge for anybody considering FTA use.. there are 2 types of cable...null modem ..and straight..they look identical and U cannot tell the difference..they both have DB9 pin female ends...all U can do is get an USB adapter (with CD Driver installed) to convert the "null modem" cable U should have, from a serial to USB port connection, which does NOT work in many cases..and u need to find the correct puter comport settings...I'm guessing U are getting a "flash failed" message, which is a communication problem (cable and/or comport) between receiver and computer..there is NO guarantee fix for this except buying a new receiver intended and USB ready or using an old puter with serial port...or keep buying various adapters with drivers until U possibly luck out and find one that will work...its that simple.. |

Silver Member Username: Hawaiian_timeKanaka freak... Post Number: 939 Registered: Apr-06 | True that. Better to get an Ultra and use a usb flash drive. |

Bronze Member Username: Saqeeb90Post Number: 36 Registered: Dec-06 | LK sorry i didn't understand what you were saying. how to i recognize b/w straigt and null modem cable. also i have DBN male end and i am using a female end adapter to use it on my megaset reciever.and i am using coolset pro loader. it detects the port setting but when i click on connect it doesn't shows me any error messasge it shows me connecting but there is nothing happening. so my question is which cable should i buy that works with my laptop . please help |

Bronze Member Username: LokbongtomPost Number: 25 Registered: Jun-06 | This one did not work at all with the FTA :http://cgi.ebay.ca/USB-to-RS232-Serial-DB9-9-Pin-Cable-Adapter-Garmin-GPS_W0QQit emZ270099983282QQcategoryZ41995QQrdZ1QQcmdZViewItem This one work but with XP you need to force to install manually two driver difference :first install the .exe file from cd ,reboot you pc ,plug the usb to serial cable XP will ask you the driver ,you have to select the driver from the cd and force its to install, it will work 100% with your FTA. but repsect the cable nul-modem or straight depend on your model FTA http://cgi.ebay.ca/NEW-for-USB-to-Parallel-Serial-Printer-Adapter-Cable_W0QQitem Z290092230692QQcategoryZ11196QQrdZ1QQcmdZViewItem |

Silver Member Username: TapemanPost Number: 748 Registered: Oct-06 | That is the issue They convert USB to serial port They don't convert USB to null To use USB you must have Windows XP no driver required (don't even think about it if you don't have XP) If you are willing to test at your own risk. I never tried it. But what will make more sense to me. If you are willing to give it a risk: - Convert your printer port to 9 Pin Male - Then use null cable It should work If it doesn't work try using 9 pin serial cable with converter. If it does't work (forget it) {additional hard wires maybe required} Just get a LAP TOP that has null cable  |

Gold Member Username: LklivesPost Number: 8238 Registered: Jan-06 | it doesn't work with printer port..and U do NOT need XP either.. |
|
Silver Member Username: TapemanPost Number: 751 Registered: Oct-06 | I was talking about USB in XP operating system You can make 25 pin serial port to 9 pin serial port. It does require cable rewiring. I havn't open rs232 for nearly 22 years. Simple pin configuration but may not be simple to FTA users. |
|
Gold Member Username: LklivesPost Number: 8243 Registered: Jan-06 | I was just simply saying U do NOT need to have XP OS installed on your computer, if using the USB port and adapter with driver on your flash cable.. |
|
Silver Member Username: TapemanPost Number: 752 Registered: Oct-06 | Fine LK, thanx No problema 9 pin 9 pin female/female null This stu*pid null cable is nothing but 4 wires Not all pins even required Here is how and why:  |
|
Silver Member Username: TapemanPost Number: 753 Registered: Oct-06 | Notice only 4 wires required in this case  |
|
Silver Member Username: TapemanPost Number: 754 Registered: Oct-06 | Or 5 wires One of these has to work I just don't remember which one Be my guest if anyone interesred  |

Gold Member Username: NydasPost Number: 2152 Registered: Jun-06 | Tru statements for IBM PC clones with various Windows Operating systems: 1. USB to Serial converter converts the signals properly. 2. If the converter you buy comes with its driver, you should preferrably use that driver over the driver provided by the OS. 3. Try to keep the overal length under 10 feet. 4. If you do not know the cable type (whether straight or null), you can always use it with an additional M/F null adaptor in series. 5. You can always check if a cable is null or straight RS232, by checking connection between pin 2 at one end and pin 3 at the other end. If your multimeter shows connection (continuity or no resistance), then it is a a null cable 6. Under Windows XP, you may get a comport other than 1-4 assigned to your USB-serial convertor, or may get a conflict with other serial ports. You should remove the conflict and also make sure that through your device manager assign com port value of 1,2,3, or 4. Also set a baud rate in the 4 digit value range. 7. In the work normally undertaken by visitors to the FTA forums (uploading of BIN), the usual problem after solving the connection problems is the use of wrong BIN or wrong uploader or unzipped files. |

Gold Member Username: NydasPost Number: 2164 Registered: Jun-06 | sada: I understand you have a USB to serial converter and a DB9 9 pin F/F cable. You are trying to use this combination on the megasat. Things to do. 1. Check via device manager. start/settings/control panel/admin tools/computer managment/device manager Find the device and make sure you have a com 1-4 port on it. 2. Make sure you are using unzipped files, which are OK for your receiver which is a clone. If the set up does not work, 3. Get a M/F 9 pin null adapter (or short cable) from Radio shack, stick it at the end of the cable and try again. |
