KNX Gateway for RS485/RS232 mainly applied in the intelligent control system and installed on the distribution boards with 35mm mounting rail, which can realize Modbus/RS485/RS232 and KNX bus communication.​KNX Gateway for RS485/RS232 powered from KNX bus, and need a 12-30V DC auxiliary supply voltage. It is available to assign the physical address and configure the parameters by engineering design tools ETS with .knxprod ( support edition ETS5.7 or higher ).  Configure basic parameters of communication, such as Baud rate, data bit, stop bit, parity bit and etc.  Channel supports Max.500 datapoints. Each function point is undirectional, which can be configured direction, name and datatype(1bit/2bit/4bit/1byte/2byte).  As Modbus master, read register data from slave and communicate with KNX.  As Modbus slave, report KNX data to master or BA system.  As normal gateway, only converting data, without communication mechanisms and logic.  Support DAIKIN, HITACHI, Mitsubishi and other VRV Air conditioners in Modbus RTU mode, independent control up to 64 devices.  Support some manufacturers of electric curtains and background music host control protocol. Operation voltage 21-30V DC, via the KNX bus Bus current <6mA 30V DC Bus power <180mW Dimension 72 x 90 x 64.1mm Weight 0.17KG Voltage 12-30V DC Current <60mA 30V DC Power consumption <1.8W KNXBus connection terminal (red/black) Auxiliary power Screw terminals Operation –5 °C ... + 45 °C Design Standard 35 mm DIN rail installation
