Serial Interface
RockREMOTE Mini and Mini OEM provide a physical serial interface for local device control, configuration, firmware maintenance, positioning data and Iridium Messaging Transport (IMT) messaging.
Connect the serial interface​
RockREMOTE Mini​
Use the 12-way Power, Serial and GPIO cable. See the connector pinout and wiring table, or the installation guide when planning a permanent installation.
RockREMOTE Mini OEM​
The OEM product exposes the serial interface through its 30-way header. Refer to the Mini OEM pinout and electrical interface notes before designing or connecting an interface board. The Mini OEM pinout is different from the RockBLOCK Pro OEM pinout.
Default settings​
| Setting | Default |
|---|---|
| Interface mode | RS232 |
| Baud rate | 115200 |
| Data bits | 8 |
| Parity | None |
| Flow control | None |
The physical port can be changed to a supported RS4XX mode or another baud rate in user.cfg. See Serial Communication in the RockREMOTE Mini User Configuration guide.
Use the serial interface​
- Use the shared AT command reference for device control, configuration, positioning and IMT messaging.
- Follow the firmware and configuration update process when transferring firmware or configuration files over the physical serial port.
- Configure GNSS NMEA forwarding in the User Configuration guide.
AT commands, serial firmware updates and NMEA forwarding share the physical serial interface. Use one function at a time. In particular, disable NMEA forwarding before using AT commands or starting a serial firmware update.
