Posted: Sat Aug 21, 2004 1:27 pm Post subject: Rookie needs help w/ interface question |
|
|
I'm having a problem with DecodeIR 2.14.
I am getting a communication error "No response from
interface. Make sure that the interface is connected to
PC, and that you have corrected the correct port."
I have run HyperTerminal on the com port (1) at 300,1200 and
2400 with the interface connected and seem to be receiving data
from that port. I am getting characters on the HyperTerminal window.
From this I am assuming that the interface cable is OK.
I have tried reversing one battery as suggested in post http://www.hifi-remote.com/forums/viewtopic.php?t=2622 but
that didn't do anything. I tried to go back to a previous version as I had read that the URC8811 wouldn't program from
the latest version, but the earlier doesn't support serial port communication.
From this point, I don't know where to go. Can anyone suggest a way to
troubleshoot this?
Thanks;
Don |

I assume you mean IR v5.x? DecodeIR.dll is a support library used by IR and doesn't directly communicate with the remote.

Go to the Interface menu in IR and make sure the Serial... option has a check mark next to it.

Try without batteries as well. _________________ Mark |

Thanks; Turns out that you CAN plug a parallel port device into a serial port.
Appreciate your response

You had me convinced you were using a serial interface when you talked about HyperTerminal. _________________ Mark |

Yeah, well I was pretty convienced to. I couldn't figure out why they would send me a 25pin connector with the wrong gender. I'm glad this is just between you and I |

Me too. I just finished my Cable, parallel, and it will not work. I read your message and it made me look again. I am OK as my system is very new and it only has a db25 for a printer. I am starting to think the pins are getting pushed in on the jp1 I made and pin 3 may be pushed. I can fix that though. I did not see where the latest IR lets you specify a port. Is it automatic?
P.S. Mark, where are you in Connecticut?
Dave, Weaver HS, Hartford, Class of...well you get the idea.

Don't the pins have ears that lock them into the plug?
If you go into INTERFACE > PARALLEL > SELECT PORT you can specify the port.
Don't forget to slow things down in the ADVANCED > TRANSMISSION DELAY
Hope this helps.

Yup...just found that.
I did see the pins lock, but I reused the shell and the plastic locks may be bad. I can take them out of the shell and place them on the jp1 1 at a time to see if it works. The parallel part looks OK and ohms out OK.
Also my delay is 1600.

OK, I am "goin in", I will open the Parallel Conector as well.
This is stupid. It is not like it is "Rocket Surgery"
I built this whole OverClocked System with Raid0 and did not have this much trouble! _________________ "It it ain't broke, fix it 'til it is" |

MSPAN, what remote are you using?
What message(s) does IR give you?
Have you tried with and without batteries in the remote?
Is your parallel port enabled?
BTW, I'm near New Haven. _________________ Mark |

Mark, our first house was in Milford. Born and grew up in Hartford and everyone I know is still there...including family.
IR Message just says that it can not find/communicate with the remote. This is on 2 systems and 2 remotes. One remote is a 15-1994 and the other is a 15-2117. Tried with and w/o batterys and even reversed 1 battery in the 2117.
Ports are fine and I have "ohmed" out the cable 10 times. Even checked out the Parallel ports and 25 is ground.
Can it be that my 5 foot cable is too long?
TIA,
Dave

So how'd you end up in Portland?
I was born, raised, and still live in New Haven county.

Is IR configured to use the Parallel... port on the Interface menu?
What message do you get when you click Interface, Driver Status...?

Is this a Simple interface? Homemade or purchased? Do you know what value resistors were used?

That shouldn't have any adverse affect. Did you check the cable itself for continuity from end to end? _________________ Mark |

Well, I am a "migrant electronics worker".
Moved from Hartford to Fairfield, then Milford when I serviced Computers at State Nat'l Bank. Then on to Colorado, California and then offerred Job in Oregon.
Anyway, cable is OK as I tested pin-out from Parallel end to jp1 end and is OK. I used 1K resistors and built the simple interface cable myself. Parallel pin 3 to JP1 6 is 953 ohms. Same on pin 4 to jp1 pin 5.
IR is configured for Parallel and will look at the driver message.

And obviously you verified the diode is oriented properly, correct? _________________ Mark |
