TS480 - RRCs connects but panel is dark

[PY1KN]

Hello

My remote setup is a TS-480, connecetc via two RRCs. The station also includes control of rotator, steppir and wattmeter via serial device servers.

After many months of reliable operation I can not connect the RRCs. When I press the power button on the TS480 panel there is no error tones, but the panel remaisn darkm there is no audio but I hear some clicks.

The strange thing is that when I open the web interface, the control RRC reports connected status. (see attached file)

I made a test, and I can connect via PC-Client normally, so I am sure everything is fine at the radio side.


I checked the 6-way TTL cable between the front panel and the RRC, and it is good.

Anyone has any clues? Should I suspect either my front panel or the control RRC is bad? Any tests I could do?

Thanks

An update...

I´ve just noticed that even though the Control RRC reports Radio ON, the Radio RRC shows Radio OFF.

It seems I can't switch the radio on from the RRC, but can with PC-Client plus ARCP-480

The units are in program mode 5 (TS480).

Hi Both Control RRC and Radio RRC should always shows radio ON when set in TS-480 mode. If the radio-RRC do not show Radio ON check the cable from radio to Radio-RRC. The Radio-RRC should show Radio ON as long as the Radio is connected to 13.8V it doesn't matter if it's ON or OFF.

Solved.

It was the TTL cable at the radio end.

Thank you Mike.
