System Integration
The T-SMINT O provides NT1 functionality without a microcontroller being necessary.
Special selections can be done via pin strapping (DIO, BUS, TM0-2). The device has no
μP interface.
The IOM -2 Interface serves only for monitoring and debugging purposes. It can be
regarded as a window to the internal IOM -2.

Normal operation
1)
The S-transceiver transmits pulses with alternating polarity at a rate of 192 kHz resulting in a 96 kHz envelope.
2)
The S-transceiver transmits pulses with alternating polarity at a rate of 4 kHz resulting in a 2 kHz envelope.
3)
Forces the U-transceiver into the state
Transparent
where it transmits signal U5.
4)
Forces the U-transceiver to go into state
Test
and to send single pulses. The pulses are issued at 1.0 ms
intervals and have a duration of 8.33 μs.
5)
The U-transceiver is hardware reset.
