Hello,
I have some difficulties to make 2nd lock work on my VTO6210BW (VTK-VTO6210BW-VTH1550CH).
I have these firmware installed:
General_VTH151X_Eng_P_SIP_V4.300.0000000.1.R.20180605.bin
General_VTOXXX_Eng_P_16M_SIP_V4.300.0000000.1.R.20190305.bin
And I use as extension:
DEE1010B
The ideea is that VTO6210BW is not sending anything on RS485_A and RS485_B, I masured the voltage on them connected to dee1010b, is 2.4V on each side (should rise to 5V in case of signal), and when i press 2nd unlock, on vth1550ch or gDMSS application, it says: "Open Lock2 Failed" and "Unlock Failed".
Also dee1010b has 3 x leds, one of power, run (who blinks, green), and unlock which it does not responds on any unlock activity.
I attached some pictures from VTO web interface.
I have no ideea what to do more....
