KNX / RS232 PROTOCOL CONVERTER

ORDERING CODE
BTCC-02/232.1

DESCRIPTION
The RS232/ KNX Controller is designed for an intelligent building control system which is used to connect RS232 devices to KNX installation. As an interface device, it supports point to multipoint one-way communication and its maximum communication distance is 15m. The KNX/EIB bus control system can send a telegram to the RS232/ KNX Controller, and then transfer to the RS232 devices by the Controller. The control commands and the technical data are different from different devices with serial port, so you must know its commands and technical data, such as the baud rate etc, before configuring it. It is the only way that the relevant parameters can be set correctly for the RS232/ KNX Controller. The RS232/ KNX Controller has two serial ports, they are called COM1 and COM2. It uses nonstandard connection, and each serial port only keeps three signal wires to achieve communication. The three signal wires are TxD, RxD and GND. The current version of the RS232/KNX Controller does not use RxD, only allow one-way communication via TxD and GND, and allow the cables to parallel in a serial port to control several devices.

FUNCTIONS / CHARACTERISTICS

  • Two serial ports with three wires, nonsupport flow control, and only support one-way communication
  • The two serial ports are independent, the length of data is fixed for 8bits, and stop bits and parity can be set individually
  • Support up to 64 serial port control commands which length could be up to 64 bytes and the baud rate and the COM port can be set individually
  • Up to 16 communication serials can be set, and each serial provides up to 6 control commands which could be sent to RS232 devices via COM1 or COM2
  • Each serial can be triggered via 1bit or 1byte communication object
