1)
If backward pulses are expected, a "Calculated channel" (see "Calculated channels" on page 50) must be used to
subtract the backward pulses from the forward pulses.
2)
The myDatalogNANOamr cannot evaluate type A3/B3 direction signal. This connection example can be used if no
backward pulses are expected.
3)
The myDatalogNANOamr cannot evaluate type A4/B4 tamper/error signal.
7.4.2 Connection of the GSM antenna
Important note: To ensure the correct functionality, only use antennas that are supplied by
the manufacturer.
The standard antenna is directly attached to the antenna cable (see "Overview" on page 16) of the
myDatalogNANOamr . In the event of a low radio signal strength, you can use the Flat antenna Smart
Disc FME-F (206.814).
If the length of the 3m antenna cable of the myDatalogNANOamr is not long enough, you can use a
5m Extension cable for Antenna 900 FME (206.805).
