Wiring of the
BUS
(Slave operation)
Up to 31 TresCon analyzers can operate together on the BUS.
The last instrument on the BUS must provide the terminating resistor
(see Fig. 8-1). If only one instrument is used, this is also the last instru-
ment and must provide the terminating resistor.
Fig. 8-1 TresCon in the BUS
This setting can be made in the software of the last TresCon in the
General Parameters menu (bus termination).
