HAPCAN installation tips and troubleshooting when assembling, commissioning and configuring devices.

I'm using the MONOSTABLE RELAY UNIV 3.2.1.0
The unit is still configured according to the firmware dbroefault startup values.
I notice that on every powerup, the unit briefly toggles all outputs from 0 -> 1 -> 0 again.
Why is it doing that? It messes up the equipment connected to it.
I have the unit connected to automatic dooropeners, and on every powercycle, the doors open once.
I'd like to avoid that.
What do I need to change in the firmware to avoid this?
If we are doing this to get the latest state broadcast on the bus, can we then please change it so that the state is broadcast without actually toggling the real output state?
This is an unexpected behaving.
Are you using the latest firmware UNIV 3.2.1.0 [rev3]?
Have you tried the firmware which is for 16A version UNIV 3.2.3.0 [rev2]? The hardware is similar, so you could do this.
What are your relays power up settings (on, off, last state)?
I will have a look in the relay firmware code.
The powerup state is all off. That's what I'm counting on, and that is what the firmware defaults are too.
But when I power up, the toggle from off -> on -> off. After that it is stable off.
It seems that I might have not been using rev3 of the firmware.
After upgrading to that, it looks like the powerup behaviour does not involve toggling the initial states any longer.
Apologies for the confusion.
