12.13.2. Getting started
Equipment

two HX0130 or HX0030 sensors

an HX0190 SUBD9 connection board (optional) or an HX0191 M12 connection board
(optional)
Configuration files

" ProfibusDP_12Mbps " for a Profibus DP bus, 12 Mbps speed, amplitude > 4 V

" ProfibusDP_inf4V_12Mbps " for a Profibus DP bus, 12 Mbps speed, amplitude < 4 V

" RS485_10Mbps " for a RS485 bus, 10 Mbps speed, amplitude > 4 V

" RS485_inf4V_10Mbps " for a RS485 bus, 10 Mbps speed, amplitude < 4 V

" RS485_19200bps " for a RS485 bus, 19200 bps speed, amplitude > 4 V

" RS485_inf4V_19200bps " for a RS485 bus, 19200 bps speed, amplitude < 4 V
, The configuration file parameters are compliant with the EIA-485 standard.
- To analyse the Profibus bus at other speeds you must create a new « .BUS »
configuration file using the PC SxBus software.
Connections
OU
HX0190 SUBD9
Pin 3 : RxD/TxD-P
Pin 8 : RxD/TxD-N
Pin 5 : RxD/TxD-N
To be analyzed, the signal
amplitude must be greater
than 700 mV.
