M1 command
If IA (I/O Input Address) is set correctly and P1 command is configured as PWM1 output, incoming AD0
samples automatically modify the PWM1 value. See PT (PWM Output Timeout).
To configure the duty cycle of PWM1:
1. Enable PWM1 output (P1 = 2).
2. Change M1 to the desired value.
3. Apply settings (use CN or AC).
The PWM period is 64 µs and there are 0x03FF (1023 decimal) steps within this period. When M1 = 0
(0% PWM), 0x01FF (50% PWM), 0x03FF (100% PWM), and so forth.
Parameter range
0 - 0x3FF
Default
0
RP command
The PWM timer expiration in 0.1 seconds. RP sets the duration of pulse width modulation (PWM) signal
output on the RSSI pin. The pin signal duty cycle updates with each received packet and shuts off
when the timer expires. This command is only applicable when P0 is set to 1 which enables RSSI PWM
output.
When RP = 0xFF, the output is always on.
Parameter range
0 - 0xFF (x 100 ms), 0xFF
Default
0x28 (four seconds)
LT command
Set or read the Associate LED blink time. If you use D5 command to enable the Associate LED
functionality (DIO5/Associate pin), this value determines the on and off blink times for the LED when
the device has joined the network.
If LT = 0, the device uses the default blink rate: 500 ms for a sleep coordinator, 250 ms for all other
nodes.
Parameter range
0, 0x14 - 0xFF (x 10 ms)
Default
0
