IOM BACNET GATEWAY

Note：The control operation of the air conditioner should not be too frequent, so that the

command cannot be executed in time and the command is lost. It is recommended that

commands be spaced at least 200 milliseconds apart.

5.4 BACnet Settings

The BACnet network number is in the range of 2~254. You need to restart the device for the

new settings to take effect. Different gateways must have different BACnet network numbers,

and the same network number cannot be used for other devices. The rules to generate the

BACnet device instance number are as follows:

BACnet device instance number for indoor unit = (BACnet network number * 10000) + (Port

number * 1000) + (Indoor unit address);

BACnet device instance number for outdoor unit = (BACnet network number *10000) + (Port

number *1000) +100+ (Outdoor unit address).

485 port number: 0~3. For the 485 port near the network port, the number is 0. Indoor

unit address: 0~63; outdoor unit address: 0~31.
