3.3.8 Terminating the sender/receiver units when operating the FLOWSIC100 with
"2-path measuring" configuration
3.3.8.1 Checking the sender/receiver unit(s) - MCU connection
Checking the termination
The connection between sender/receiver units and MCU must be terminated at the start
and end with resistors for both single and bus wiring. The terminating resistors are already
on the circuit boards and are activated by
plugging jumpers on the respective pins.
