JP1 Remotes

Posted: **Fri Aug 16, 2019 8:17 am**

I have: Ubuntu (Linux) Mythtv V30 in home build box, USB IR receiver, URC-7130 essence R02, Logitech K120 wired keyboard in use, RM, RMIR, RMPB, Bookmarked web site https://www.mythtv.org/wiki/Programming ... _Keyboards , JP1 Adapter and JP1.2/1.3 (FLASH) USB Cable for Universal Remotes. I can start RMIR but when I select download(I presume from remote) it says 'no remote found'. Adaptor is at ttyUSB0 and it is listed in the USB devices(lsusb). I have tried all 4 different combinations of cable and adaptor, with and without batteries in the remote. What setting am I missing in RMIR? Any other clues could help.

In RMIR, trying explicitly setting the serial port:

Remote > Interface > JP1.X Serial...

Choose Other and enter ttyUSB0

Thanks Greg but I have already done that, it put another entry in the list.

I may be wrong or misreading this

But are you using a JP1 adapter in addition to the JP1.x cable?
If so, then you should leave the JP1 adapter out and only use the cable to connect to the remote. The reason why is becuase you have a JP1.3 (I think) remote

Also, did you try /dev/ttyUSB0

/dev/ttyusb0 is rw for the dialout group which I am in, so thats out.
I have tried the cable without the adaptor, both ways and with and without batteries. No joy.
The board in the remote is labelled as jp1-4(not jp1.4), if this means anything.
Thanks rem and greg.

If your remote is JP1.4, you definitely should NOT be using the legacy JP1 adapter.

Sorry The Robman. I repeat that it is labelled 'jp1-4' not jp1.4. I have not heard of the URC-713x series being jp1.4. It is about 3 years old, could it be?

For the UK remotes, I notice the JP1.x socket within the battery hatch will be shaped like an AA battery symbol/shape.
So Pins 5&6 will are on the end with the notch and pins 1&2 are on the flat end.
Eg using the AA battery shape pins 5&6 will be the +ve end, pins 1&2 on the -ve end.
ie from a vertical view

or from a horizontal view

You mention diygadget.com in an earlier post, so I tried looking it up to see what you're working with

Top image shows the pin assignments on the connector

There are 2 USB JP1.x cables at diygadgets.com
One is a FTDI type, the other is not. I wonder if there are functional differences between them when used in Linux?

The cable I use in Linux Mint is the 'original USB FTDI' bought from ebay as mentioned in this forum, so I am using an FTDI type in Linux Mint.

So when I check the messages after connecting the cable I see this

Anyway - these are my suggestions in no particular order
Make sure you know which way the connector goes - if possible try another remote
Check your cable works by using another machine/pc
Eg you may wish to try another machine
a windows machine or
another Linux pc or
boot from Live Linux http://www.hifi-remote.com/forums/viewt ... 5&start=88 which starts at
