Door station DIP setting
Total 3 bits can be configured, bit-1 and bit-2 are used to assign ID code for door station, bit-3 is
used to match the video impedance.The switches can be modified either before or after installation.
Note: if the video impedance need to match, please set the bit-3 on.
Indoor monitor DIP setting
There are 6 bits in total. The DIP switches are used to configure the user code for Monitors.
Bit-6 is an video impedance match switch, which have to be set to ON if match the impedance,
otherwise set to OFF.
Bit-1~Bit-5 are used to set user code, to DT595A door station, the user code should set to 0~15.
