    Co-operate with the SM7 Module Lumel Heat and Lumel 3000 systems communicate with industrial devices by means of COM serial ports. The SM7 module does not require the installation of whatever programmable logic controller. In case when there is not enough of serial ports in the computer, one can increase this number installing a PD10 or PD12 USB converter on the bus, what extends computer resources with additional COM ports.
  • Page 11 4. SM7 MODULES PRINCIPLE OF OPERATION The SM7 radio transmission module enables the radio communication of devices equipped with an RS-232 or RS-485 serial port. The maximal baud rate in the radio channel is 76800 bit/s. This rate can be changed in the range: 4800..76800 bit/s.
  • Page 12 - baud rate: 9600 bit/s - transmission mode: 8N2 To switch the SM7 module into the configuration mode, one must press for three seconds during the module operation, the button being at the bottom of the housing. The button location is presented on the fig.6.
