Serial transmitter 7100 is exceptionally versatile andaccepts all common temperature and process signal inputs. You can connect its digital output direct to devices having RS485 serial port. The 32 transmitters may be connected to one serial bus. Transmitter suits for appli- cations where digital input is required, like PC serial port or programmable logic controllers. Nokeval serial converter 711 can execute RS485/RS232 conversions (two RS485 ports) if only RS232 port is available. Serial transmitters are slightly more accurate than transmitters with analog output because you do not need to convert output to current or voltage output signal. The linearity of A/D-converter is
