Specifications
Supports the RS485 or POE power supply.
● Supports eight RS485 or AI/DI signal inputs.
● Can connect to sensors such as the smoke sensor, water
sensor, door status sensor, and infrared sensor.
● Each port can supply power. Two RJ45 ports share one
12 V DC power supply that is controlled independently.
The maximum output current is 900 mA when the
voltage is 12 V. (COM1/AIDI_1 and COM2/AIDI_2 form a
group, COM3/AIDI_3 and COM4/AIDI_4 form a group,
COM5/AIDI_5 and COM6/AIDI_6 form a group, and
COM7/AIDI_7 and COM8/AIDI_8 form a group).
● The 12 V DC power supply can be switched on or off
and is on by default.
Connects to the ECC800-Pro through the POE port.
● One 4-bit DIP switch is used to set the RS485 address.
● OFF indicates 0 and ON indicates 1.
● Bit 1 is the least significant bit, and bit 4 is the most
significant bit. For example, if the board address is 5, the
corresponding bits are ON, OFF, ON, and OFF, and the
corresponding binary number is 1010 (ON is 1 and OFF
is 0).
