'''S.Port (inv.)'''<br />

'''S.Port'''<br />

When it comes to sending telemetry data back to the radio it get's more complicated. There is an older system called S.PORT that allows to send telemetry data using a second line. This was firstly introduced for RC drones. One problem here is that the signal is electricaly inverted similar as it is done with Futaba SBUS. But as most controllers do not have signal inverters by default, FRSky did add an inverted S.Port signal to some of their receivers. So that protocol can be read as "normal" UART. If you've got one of those receivers you can use it in combination with MICROBEAST PLUS / ULTRA and NANOBEAST. Please note that you need to add an additional '''10k resistor''' between signal line and ground/minus in order to stabilize the signal!<!-- The MICROBEAST ULTRA has an inverter built in, so here you can use receivers with the original S.PORT.--><br />

You can also use the StudioX app to start receiver scan and perform further setup steps. In this case open the '''Control''' menu in StudioX and click the '''SCAN''' button in this menu's screen. For further informations please refer to the StudioX instruction notes.<br />

Please note that when using S.PORT (inv.) telemetry connected to [SYS], you must disconnect the receiver from [SYS] temporarily, switch off your radio and power cycle your device. It will then enable "normal" [SYS] operation for programming purpose. When using F.Port connected at [SYS] in combination with MICROBEAST ULTRA you can connect your BLE2SYS/USB2SYS at the DI2 port at the side of the device using the [https://www.freakware.de/en/p/adapter-cable-telemetry-adapterkabel-micobeast-beastx-bxa76406-a174871.htm Telemetry adapter cable BXA76406].<br />
