Frequency Table (MHz)
*** E4(5645) & E8(5945) are disabled by default.
Frequency Selection (Button)
Press Button A to select the Group, Press B to select parameters in each Group.
When LED blinks, Group & parameter can be changed
New Frequency & Power will be saved if no button action within 5 seconds.
The VTX remains the current frequency until new setting is saved.
PIT mode: Press B to enter PIT mode(1mw output), Pit LED blinks
Press B again to quit PIT mode

PINIO Power switch
Any unused RX/TX/motor/PWM pad can be remapped for PINIO in BetaFlight
e.g. F405-CTR TX3 is used for CMS control, connect PINIO pad to RX3 of F405-CTR
CLI resource to locate RX3 pin name
RX3 pin is C11
then
resource SERIAL_RX 3 none
resource PINIO 1 C11
set pinio_box = 40
save
Go to modes tab and assign an AUX channel to the USER1 mode. Click SAVE.
Flip the switch and test
VTX Power OFF VTX Power ON
Tips
If FC has PINIO power switch built-in, e.g. F722-SE, F722-mini, no need to use this VTX PINIO function.
VTX PINIO would cut 5V output, so don’t power your FC via VTX 5V pad if you want to use this function.
CMS control
Protocol: Tramp(TR)
*** CMS would override the button control if CMS control is enabled.
TR power level vs VTX power level
TR PIT -- VTX PIT
TR 25 -- VTX 25mw
TR 100 -- VTX 200mw
TR 200 -- VTX 200mw
TR 400 -- VTX 400mw
TR 600 -- VTX 800mw
CLI
vtx_low_power_disarm = OFF
Allowed values: OFF, ON, UNTIL_FIRST_ARM
If ON and the flight controller is disarmed, the video transmitter output power will be set to 25mw
Otherwise, the video transmitter output power will be set to the configured value.

VTX CLI command
DFU
SH1.0-8P
20602
ICM
STM32F722RET6
MCU
1. Connect VTX TX/RX to one of FC UART
VTX RX to FC TX, VTX TX to FC RX, Common ground
2. Connect FC USB to your computer
3. Connect FC to BF configurator
4. Power ON VTX
5. Type Serialpassthrough code in CLI & press the keyboard “Enter”
If using the FC UART1, Type “Serialpassthrough 0 115200”
......
If using the FC UART6, Type “Serialpassthrough 5 115200”
*** Following command is in VTX firmware,
It is not related to BF command
6. Type “help” after FC forward the port
7. Type “config list” to check VTX setting
E4_5645 and E8_5945 are disabled by default
8. Type “set freq 5645 = enable” to enable E4
Type “set freq 5945 = enable” to enable E8
9. You can also enable/disable whole band
e.g. “set band A = disable”
10. If Freq/band is disabled, button control will jump over it.
11. Unplug USB & battery,
Serialpassthrough mode will be invalid.
