|
|
I created the transister based serial cable for my one for all urc7960. I tried downloading the remote data but remote master shows no remote found.
can someone help me in debugging the problem.
I am connecting the cables based on the pin number of the jp1 connector on the remote.
using windows 10 64bit, with remote master 2.03
Thank you |

well, the primary suspect is the cable that you built, so my guess is people will need a lot more info on the cable in order to help. _________________ Rob

Is this primarily an exercise and trying to build something yourself or do you just want a working cable? Because if it's the latter, I would just spend the $9 on buying a cable on ebay.

I have a serial port on my pc, and the circuit of the cable was not difficult. so i decided to create it myself.
the link you posted, isnt it a usb to serial cable only??
sorry if i am wrong. |

Maybe I misunderstood what you are trying to do. The cable that I linked you to is a USB cable that can be used to program a JP1 remote, the only thing missing from it is a standard 6-hole JP1 connector, but if you are able to build your own devices, I assumed that wouldn't be a problem. _________________ Rob

|
|
Thank You Robman for the link.
The cable is USB TTL Serial. The only difference between the original serial on our PC and this is the vcc voltage, which is 5 volts or 3.3 volts for high in this.
however i am confused about the pinouts. you are not connecting the vcc, i.e the pin 1. and pin 5 on the remote side?
are we suppose to remove pin 1 and pin 5 on the jp 1.3 cable??
thank you in advance. |
