FIELD TEST DEVICE sigfox RC2 - Guide utilisateur / User guide version V1.0.0
The screen will display:
• The number of frames sent (UL COUNT), including repetitions
• The number of frames received (DL COUNT)
• The Packet Error Rate (PER) as a percentage
The PER measurement is calculated by comparing the number of frames transmitted to the number of frames received:
• PER (%) = 100 - (DL_COUNT/UL_COUNT) * 100

IMPORTANT : in this menu, a long press will allow you to reset the counters to zero.

This menu can be accessed by briefly pressing on pushbutton 2 after the PER menu. It will allow you to view a downlink frame sending by the
network. This frame is displayed in ASCII caracters. The non printable caracters are replace by a point.
The screen allow a viewing of 51 caracters (17 caracters per lines). If the size of the payload is upper than 51 bytes, the product will not display
the extra bytes.

4. DECODING THE PAYLOAD

The size of the Field Test Device's payload can vary depending on the information transmitted. The first byte will enable you to identify the pres-
ence of information contained in the payload. Information will always be shown in the order indicated in the following table.
The frame is transmitted either periodically or on event following a press of the button. Depending on the communication mode (monodirectional
or bidirectional) defined by the S382 register, the interpretation of the end bytes of the frame is different:
Example of a payload received: 8C1B45159690005534502020
This example will be used in order to explain how the payload is decoded.
