Pluto Relay Mod Fault?

[glen_turner2002]

Hi,

I've fitted the relay output mod to the Pluto and and i cant get the relay to switch. Is there something i need to enable in the new firmware?

I cant measure anything on the GPIO pins.

Has anybody had this problem?

What firmware are you using. Only the F5OEO firmware works.

Also why is D1 fitted? http://www.farnell.com/datasheets/1633363.pdf

Hi Mike,

Thanks for the reply. Yes the new firmware is installed and I thought I needed the diode. Will fitting the diode prevent it from working?

You only need the diode if you buy a relay without a diode already fitted. It should not make a difference - look at the schematic and analyse. When you say it does not work what do you mean? How are you trying to operate the relay? I assume in the web interface of the F5OEO software?

I'm sending a stream via Vmix and expected the relay to energise when it's got a stable stream, but it doesn't.
I know the Vmix stream works.

Am I doing something wrong? I've read the info and i think it should have worked.

I don't know. Are you sure the diode is in the right way around, the transistors are what they claim to be and the 1k5 resistors really are 1k5?

When you say sending stream via VMIX, are you using the PTT button on the interface? The one that controls the PTT relay? Transmit ON / OFF?

I am afraid I can't help much more as I gave up on VMIX a long time ago due to the HD restrictions and use OBS and UDP. Latterly with FFMPEG as it's much better at coding. You can do the same with VMIX I think.

This is a batch file for H264 to the Thursday net on QO-100 with OBS. FFMPEG needs to be downloaded and installed.

c:\ffmpeg\bin\ffmpeg -f dshow -i video="OBS-Camera" -thread_queue_size 512 -f dshow -i audio="OBS-Audio" -vcodec h264_nvenc -s 1280x720 -r 15 -bf 0 -pix_fmt yuv420p -b:v 300k -preset slow -profile:v main -rc cbr_hq -rc-lookahead 5 -acodec aac -aac_coder twoloop -ar 48000 -ac 1 -b:a 32k -f mpegts -muxrate 440k -streamid 0:256 -streamid 1:257 -max_delay 1500000 -metadata service_provider="MyCall" -metadata service_name="MyName" -y "udp://192.168.2.1:8282?pkt_size=1316"

For VMIX use the appropriate VMIX external output sources for audio and video. If you don't have an Nvidia card, get one. Alternatively use the standard H264 codec, libx264 in place of h246_nvenc

Hi,

I thought the stream switches on the relay?
It says under "PTT output" The PLUTO Firmware now supports a PTT output so that when a valid RTMP stream starts the PTT pin changes state to allow amplifiers etc to be keyed.

I don't have the ADLAM-PLUTO DATV Controller screen like you have, I've googled for it but i cannot find it. If need that to switch the relay on can you give me a link please?

All the components are from Farnell and are correct plus the diode is in the correct way around.

Thank you so much for your help.

Just put the pluto address into your web browser. It also has all the instructions for using the stream
