• TX Voltage
: To display the voltage for the
transmitter's battery.
• RX Voltage
: To display
the power supply voltage
for the receiver.
• Signal strength
: To display the signal strength
between the transmitter and the receiver. It is
calculated by using SNR. The signal strength will
be displayed as a value between 0 and 100. In
the same environment, the farther the distance,
the smaller the value. If the signal strength
drops to 4 or below, the system will alert the
user.
• RSSI
: To indicate the power of the signal
received by the receiver. 0 to -40dBm: Indicates
that the distance between transmitter and
receiver is close and the communication quality
is best. -40dBm to -85dBm: The communication
quality is good. Less than -85dBm: Indicates
that there is an obstacle between the transmitter
and receiver or the distance is far. Please
shorten the control distance to avoid losing
control.
• SNR
: The signal-to-noise ratio refers to the
decibel difference between the signal and the
noise received by the receiver. The signal-to-
noise ratio equals the data of RSSI subtract the
data of Noise, which is a decisive parameter
in the overall quality of the signal. If the SNR
drops below 11, reduce the range quickly to
prevent loss of control.
• Noise
: Noise is generated due to interference
from other nearby transmitters such as
WIFI. In places where there are too many
transmitters, excessive noise will affect the
remote-controlled distance.
• The ID number 1 represents the transmitter
• The ID number 2 represents the receiver
or the primary receiver(Multi-receiver
connected), and its related information,
such as signal strength, RSSI, Noise, or SNR.
• The ID number 4 represents the first external
sensor connected to the receiver, and so
on. There are up to 15 senseors can be
connected.
