The Radiomaster ER6GV receiver has been specially designed for glider
pi lots who require a compact and slim receiver. It can drive up to 6 servos
and has bui lt-in receiver voltage teleme try and flight battery telemetry
with the ability to automatically detect which voltage input to use. The ER6GV
features a dual-antenna with telemetry power up to 50mw. The ER6GV receiver
does not have a built-in al
timeter for competitions that prohibit the use
of vario. The ER6GV can be used wi th a 1S Lipo receiver battery.
2. The maximum input voltage for the EXT-V (external voltage input) telemetry
reading is 35V. Do not exceed 35V or the receiver will be damaged.
3. The EXT-V of the ER6GV is accessed via the EXT-V solder pad on the PCB.
A single wire must be soldered to this pad and connected to the
positive wire
of the battery or ESC. If no EXT-V power source is found, the ER6G will default
to reading the voltage on the receiver pins, only one voltage input can be used
at the any given time.
4. Please ensure that the power supply current of the ESC BEC matches the power
consumption requirements of the servo used. If using hig h-voltage and
high-torque servos, it is recomme
nded to use a 2S 7.4V battery for direct power
supply or a suitable high-current UBEC.
5. Calibration of the telemetry voltage will be required on your radio. Navigate
to the TELEMETRY page on your radio and locate the RxBt sensor. Edit the
SENSOR settings and adjust the offset until the displayed reading matches
the actual voltage of the battery in the model. If there is a large
difference,
adjustment of the ratio may also be required. *For best results calibrate the
voltage of your radio using a fully charged battery of the correct cell count
intended for use in the model.
6. Channel 6 on the receiver must not be used as the power input channel and may
out be used as a servo output channel. Power from an ESC or Receiver battery
must only be applied on
Channels 1 to 5.
7. ExpressLRS Arming requirements and the use of Channel 5: CH5 is required by
ExpressLRS to set the Arm state of the RF module in your radio. It is recommended
to assign CH5 to a switch such as your throttle cut switch as this will provide benefits
such as dynamic power. Using the ExpressLRS LUA or the Wifi WebUI, you can
assign different channels to the CH5 outpu
t of your receiver. See example to the
right: Please visit https://www.expresslrs.org/ to learn more on the importance of
setting up arming.

PASSPHRASE BINDING
1. OPEN the ExpressLRS LUA and navigate to the Wifi Connectivity page. Select the
Enable WIFI option and connect to your radios wifi with a mobile phone, tablet or PC
(See TX WIFI info above). OPEN
the ExpressLRS web page at (http://10.0.0.1/)
and choose a unique bind phrase. Save and Reboot.
2. Power ON the receiver and wait 60 seconds for the LED to blink rapidly to indicate
WIFI mode. Connect your phone, tablet or PC to the receivers WIFI (See RX WIFI
info above). OPEN the ExpressLRS web page at (http://10.0.0.1/) and enter the
matching bind phrase previously entered on yo
ur radio. Save and Reboot. Once both
radio and receiver have the same bind phrase set they will automatically bind.
TRADITIONAL BINDING
1. The first time you power on your receiver, the LED is doing a quick double blink,
which indicates the receiver is in bind mode. If this is not the case, hold down the boot
button for 10 seconds to reset the receiver.
2. Power ON your transmitter/radio
and use the [BIND] button on the ExpressLRS Lua
script, which sends out a binding pulse.
3. If the receiver has a sol id light, it's bound!
*Note: To bind receiver a second time or to another radio, power cycle the
receiver 3 times. On the third power cycle, the LED will double blink indicating
bind mode. If you cannot successfully enter bind m
ode with the 3 power cycle
method, you can hold down the boot button for 10 seconds to reset the receiver to
bind mode or use the passphrase method. WARNING: All previous settings in the
receiver will be erased and need to be re-entered when using the reset button.
SET-UP
1. The recommended ELRS LUA settings on the remote-control end are:
(*Note: Bind phrases are not secret and can be read.)
