Figure 5-29 Diagnostics (ZXT9-RM)
Diagnostics: Access diagnostic parameters.
VR
– Firmware Version: Read module firmware version number. Read
Only Function.
HV
– Hardware Version: Read module hardware version number.
Read Only Function.
SH
– Serial Number High: Read high 16 bits of 32 bit unique serial
number. Read Only Function.
SL
– Serial Number Low: Read low 16 bits of 32 bit unique serial
number. Read Only Function.
RP
– RSSI PWM Timer: Set/read duration of PWM (pulse width
modulated) output. The PWM output encodes fade margin (RX signal
strength relative to RX sensitivity) by varying the duty cycle of a 125Hz
square wave. The range is 0x0 to 0xFF
TP
– Board Temperature: Read current temperature of module in
degrees Celsius (8-bit twos-complement, eg. 26C = 0x1A, -10C =
0xF6). Read Only Function.
%V
– Board Voltage: Read supply voltage to module (VCC) multiplied
by 65536 (eg. 5.02V = 5.02*65536 = 0x5051F, maximum of 5 digits
returned). Read Only Function.
DB
– Receive Signal Strength: Read signal level of last good packet
received (RSSI) in dB (reports absolute value, eg. -88dBm = 0x58,
accurate between -40 dBm to RX sensitivity). Read Only Function
ER
– Receive Error Count: Set/read number of RF Packets rejected
because of bit errors in packet. Read Only Function.
