Page 6: General Information
RESI® 4 General Information Our RESI-KNX-MBMASTER gateway connects a KNX bus system to MODBUS/RTU slave devices, which have a serial RS232 or RS485 interface. The gateway offers an integrated KNX bus coupler with 2-wire connection. The time-critical KNX communication is handled directly in the gateway. On the MODBUS/RTU side, our module is a MODBUS/RTU master. - Page 7 LED indicator Clamps Clamp wire cross section Max. 1,5 mm² CE conformity Tightening torque Max. 0.5Nm IT Accessories Use our free software to configure and test the mapping between KNX and MODBUSConfigurator MODBUS register.
