ERD97P21-AUX Auxiliary relay will turn on but can not be turned off.
DX4700 or DX4800 series DVR/HVR currently does not support the unlatching of relays when used with ERD97P21-U and ERD97P21-AUX. Additionally, the KBD300A with KBD300USBKIT interfaced to DX47/DX48 does not provide unlatching of relays.
NOTE: The interface of the listed products only provide the ability to trigger the relays NO or NC.
