Bus termination for S4 transmitter
To terminate the bus if the instrument is at the end of the bus cable, the termination components in the S4 transmitter can be used. To do so,
close both hook switches in the connection area of the transmitter.
Important
If the transmitter module is removed, bus termination is also canceled.
