Downlink
This feature is available on ACW-TM1D models that meet the following conditions:
Application software:
Radio firmware:
SIGFOX version
V7.10
or higher
v5931
or higher
LoRaWAN version
V7.10
or higher
v2.3.3
or higher
The USB configuration of these products requires an ACW configuration tool of version
4.4.0
or higher.
The document ATIM_ACW-DLConfig explains how the downlink works and is available at the below link:

The parameters specific to ACW-TM1D-HP models are:
a.
Keep-alive frame frequency
Parameter code (Byte 1)
Parameter value (Byte 2)
0x03,
0x00 = Deactivated,
0x04 = every 10 min,
0x05 = every hour,
0x0A = every 2 hours,
0x0B = every 4 hours,
0x0C = every 8 hours,
0x06 = every day,
0x0D = every 2 days,
0x0E = every 3 days,
0x0F = every 4 days,
0x07 = every week (7 days),
0x08 = every month (30 days).
b.
Mode of operation
Parameter code (Byte 1)
Parameter value (Byte 2)
0x0A
0x00 = Periodic,
0x01 = Energy Saver.
c.
Lower threshold
Parameter code (Byte 1)
Parameter value (Byte 2)
Parameter value (Byte 3)
0x0B
0xYY
0xZZ
For a threshold in °C with a precision in sixteenths of a degree °C, 0xYY and 0xZZ are calculated as follows:
0𝑥𝑍𝑍𝑌𝑌 =
𝑡ℎ𝑟𝑒𝑠ℎ𝑜𝑙𝑑 × 10000
625
The threshold must fall between -55.0°C and +125.0°C.
d.
Upper threshold
Parameter code (Byte 1)
Parameter value (Byte 2)
Parameter value (Byte 3)
0x0C
0xYY
0xZZ
For a threshold in °C with a precision in sixteenths of a degree °C, 0xYY and 0xZZ are calculated as follows:
0𝑥𝑍𝑍𝑌𝑌 =
𝑡ℎ𝑟𝑒𝑠ℎ𝑜𝑙𝑑 × 10000
625
The threshold must fall between -55.0°C and +125.0°C.
