Door Entry DS-KD8003-IME1 Not Connecting to iVMS4200?

[TippRocks]

Hi,

I have a DS-KH6320-WTE1 (11/2023) with DS-KD8003-IEM1(B) (11/2023) connected through a Wi-Tek 4GE PoE unmanaged switch.

The DS-KH6320-WTE1 is activated and connected to iVMS4200. I also have a DS-KD-KP connected to DS-KD8003-IEM1(B).

The DS-KD8003-IEME (B) & DS-KD-KP will not appear on iVMS or SADP. Both have power. Any ideas on what is wrong?

Thank you for all help.
