Hi,
?
It's like this:
?
- YD6016LN provides a green heartbeat LED. As long as there is power and the module is not broken it will blink: ***.***. etc.? Frequency about 1 Hz. ( note that alle powered YaMoRC modules have this LED )
- YD6016ES provides a two green LED, one on IN and one on OUT.? Both flash rapidly when data is transmitted.
- all YD6016xx have a red activity LED which lights up ever brighter the more inputs are active
?
- DR4088LN provides a green(ish) LED that blink s with about 2Hz. when power is on and module is not broken.
- DR4088 have a red activity LED, that flashes for every occupied input from the module and/or any "upstream" modules
?
==> If a DR4088's activity light dos not flash, there are probably no active inputs.
