If you build only this driver from the INDI source tree, the build target is also indi_pegasus_flatmaster_neo.

Connectivity

Section titled “Connectivity”

USB Serial

Section titled “USB Serial”

The FlatMaster Neo uses a USB serial connection. The driver scans serial ports and matches devices whose system name contains FlatMaster.

  • Default baud rate: 9600
  • Supported connection: USB serial only
  • Network / Bluetooth: not used for the serial interface

First Time Connection

Section titled “First Time Connection”
  1. Power on the FlatMaster Neo.
  2. Start the driver from an INDI client or manually with indiserver -v indi_pegasus_flatmaster_neo.
  3. Select the detected serial port or allow automatic scanning.
  4. Click Connect.

The driver handshakes with the device using F# and expects a response containing FMNEO.

Operation

Section titled “Operation”
  • Connect the FlatMaster Neo via USB and start the driver.
  • Use Light Box to control panel power and brightness.
  • Use Dust Cap to park, unpark, or set the cap angle.
  • Use Dew Control to manage heater power, auto dew, aggressiveness, threshold, and save settings.
  • Monitor temperature, humidity, and dew point in Environment.
  • Apply calibration offsets when sensor readings differ from a reference.
  • Use Network for WiFi and hotspot management if supported by your firmware.
  • Use Overview to verify device state, uptime, and reboot when needed.

Troubleshooting

Section titled “Troubleshooting”
  • If the driver cannot connect, verify the FlatMaster Neo is powered and visible as a serial device.
  • Ensure no other application is using the same serial port.
  • Confirm the handshake returns FMNEO; otherwise the connected device may not be supported.
  • If values do not update, reconnect and ensure the device responds to FA, ES, and CR.
  • For network issues, check SSID, password, and WiFi availability.
