- Plug your astronomy camera, guide camera, or other USB-powered accessories into the available USB 3.0 Type-A, USB 2.0 Type-A, or 5V 2.5A MAX Type-C interfaces.
5.4 Connecting Dew Heaters and Sensors
- Connect your dew heating belts to the PWM1-2 RCA Interfaces. These channels allow for automatic control based on environmental data.
- Attach the Temperature and humidity sensor to the 2.5 T+H port and the Temperature probe to the 2.5 Temp port. These sensors provide data for intelligent dew point control.
6. Instrucións de funcionamento
6.1 Control de potencia
The SV241 Pro allows for remote power control of connected devices. The DC 5.5*2.1 Switch 1-5 interfaces can be individually controlled via software. The 'Always on' interface provides continuous power.
6.2 Compatibilidade de software
The SV241 Pro is fully compatible with NINA (Nighttime Imaging 'N' Astronomy) software. This allows for seamless integration into mainstream astrophotography workflows for direct power control and status monitoring. Firmware has been upgraded to V1.2, adding Power-off Memory functionality.
