Channel changer arguments

[qznaught]

I am using a USB-UIRT as my second channel changer.
I have a batch file that uses uutx.exe to change the channel and use a 3 digit string as argument to change channel
If I enter channel.bat 234 in cmd.exe it changes the channel on my set top box to channel 234.
However when I entered this in nextpvr it did not change the channel.
Here is relavant part of log and attached is screen shot of device setup.

2017-10-31 21:15:24.788 [DEBUG][10] About to tune graph to:
<tuning>
<type>HDPVR</type>
<locator>
<channel>3</channel>
<input>0</input>
<audio_input>RCA Audio Input</audio_input>
<blaster_executable>C:\Windows\System32\cmd.exe</blaster_executable>
<blaster_args>/c c:\users\anita\desktop\uutx_0_3\channel.bat {channel}</blaster_args>
</locator>
</tuning>


Can anyone tell me what I am doing wrong

Can you post the logs show and attempt to either watch or record this channel?

It might be that the recording service runs as a System account and doesn't have access to C:\users\anita. Can you try it somewhere else like C:\Temp or C:\Users\Public\NPVR\scripts?

Here is part of log preceding the above the file is too big for me to attach.

I copied the cmd.exe file and .bat file to C:\users\public\npvr\scripts and put
executable: C:\users\public\npvr\scripts\cmd.exe
argument /c channel.bat {channel}

it did not work

I tried coping to C:\program file (x86)\NPVR\ (This is where I had to copy Haupblast.exe to make my other colussus and set top box work)
executable: C:\program file (x86)\NPVR\\cmd.exe
argument /c channel.bat {channel}

Originally this did not work but I had failed to copy uutx into the folder after I did that it finally worked.

It had definitely run that command then. There was possibly something wrong with your batch file, like assuming the current path when executed. You probably just needed an explicit "cd ......" command, or full paths to any executables or data files.

I have the same setup
Exec: C:\uutx\Pace110_Changer.bat
Arguments: {channel} Pace110-z3.dat

Pace110_Changer.bat:

rem Remote# is %2
rem Dishchanger.bat {channel #} {Remote File Name #}
rem usbuirt fix
set sleep=0
set loops=5
:WAIT
IF EXIST c:\uutx\usblock.dat (GOTO PING) ELSE (GOTO CC)
ING
timeout 1
set /A sleep=%sleep%+1
IF %sleep% EQU %loops% GOTO ERROR
GOTO WAIT
:CC
ECHO wait_lock > c:\uutx\usblock.dat
#Hasn't been working, may not need it?
#c:\uutx\devcon.exe restart USB\VID_0403*
set input=%1
#timeout 2
if not "%input:~0,1%" == "" c:\uutx\uutx.exe -r1 -f%~dp0%2 %input:~0,1%
if not "%input:~1,1%" == "" c:\uutx\uutx.exe -r1 -f%~dp0%2 %input:~1,1%
if not "%input:~2,1%" == "" c:\uutx\uutx.exe -r1 -f%~dp0%2 %input:~2,1%
if not "%input:~3,1%" == "" c:\uutx\uutx.exe -r1 -f%~dp0%2 %input:~3,1%
del c:\uutx\usblock.dat
exit
:ERROR
ECHO %DATE% %TIME% >> c:\uutx\changer_error.log
GOTO :CC

Pace110-z3.dat contains the IR changer codes
