Hi All,

I am new to the remotecentral forums having recently purchased a NEVO SL. I am trying to get a discrete on and off code working for macro purposes. On the Naim forum they have told me the codes are RC5 100 and 101. I have used MakeHex and produced the codes below but they still don’t work. Has anyone any experience with NAIM products and in particular the NAIM N-VI? What do you think I could do differently to get the correct code?

Many thanks Tony

Device=27
Function=101
Define T=0

Protocol=RC5
Frequency=36000
Time Base=889 '888.89 = 32 cycles at 36Khz
Message Time=128 '128 times TimeBase
Zero=1,-1
One=-1,1
Prefix=1 'Officially -1,1 but starting with off is silly
First Bit=MSB
Form=;*,~F:1:6,T:1,D:5,F:6

Device Code: 27 Function: 100
0000 0073 0000 000A 0040 0020 0020 0040 0020 0020 0040 0040 0020 0020 0020 0020 0040 0020 0020 0040 0040 0020 0020 0CC5

Device Code: 27 Function: 101
0000 0073 0000 000A 0040 0020 0020 0040 0020 0020 0040 0040 0020 0020 0020 0020 0040 0020 0020 0040 0040 0040 0020 0CA4

Where did you get device code 27 from?

Did you get any more codes from that forum to help deduce what they really mean by "100 and 101". Maybe they mean function numbers 100 and 101 of some device number, but I doubt it.

More likely 100 and 101 mean functions 0 and 1 with device code 1.

Hi John,

This was my posting to the Naim home theatre forum:

Hi All,
I am in the process of setting up a NEVO SL courtesy of EBAY. Although my sold "As New" device has a nasty crack on the top :-( . To the point is there a way of issuing a discrete power on and power off code for the N-Vi that I can teach the device? It would be really great with macros.

I have thanks to the forum found the discrete input codes.

Regards and Happy New Year all.

The response was short and sweet:-
---------------------snip-----------------
RC5 system code 27 - 100 power on
27 - 101 power off
Sorry, no experience with the NEVO SL here–you're on your own. The discrete codes are best used in the context of a Philips RC5 codeset database already provided for the NEVO (you'll need to download v.2 of the NevoStudio software) or imported from an existing Philips PCF/CCF file.
-------------------------------------

I took the 27 and 100 and pasted that into the MakeHex utility to come up with the hex codes in my first posting - Have I completely misunderstood the response and what I was supposed to do? Thanks for any input.

Regards Tony

Now that I see that response from the other forum, I see that you interpreted it correctly and used MakeHex correctly and generated the Pronto Hex that corresponds to the signals specified by that response.

I don't know why they don't work. Sorry, I don't know anything about the NEVO nor the Naim.

Do you have other functions of the Naim working with the NEVO? Or were On and Off the only functions you were going to use?

If you have Pronto Hex for any working function of the same device, that would help a lot toward understanding why the discrete codes you tried didn't work.
