The S-transceiver transmits pulses with alternating polarity at a rate of 192 kHz resulting in a 96 kHz envelope.
The S-transceiver transmits pulses with alternating polarity at a rate of 4 kHz resulting in a 2 kHz envelope.
Forces the U-transceiver into the state ’Transparent’ where it transmits signal SN3T.
Forces the U-transceiver to go into state ’Test’ and to send single pulses. The pulses are issued at 1.5 ms
intervals and have a duration of 12.5 µs.
The U-transceiver is hardware reset.
