Based on the firmware string, we can infer the physical device:
| Component | Specification | |-----------|---------------| | Main Chip | Ali M3606 (LQFP-128 package) | | Flash ROM | 1 MB (e.g., 25Q80BV) | | SDRAM | 1 MB (e.g., IS42S16100) | | Tuner 1 | Typically an RDA5812 or similar single PLL | | Tuner 2 | Identical to Tuner 1, sharing the same front-end via a switching diode | | Demodulator | Integrated in ALI3606 (DVB-S only, not S2) | | Power Supply | 12V DC at 1A, or internal switching supply | | Connectors | 2x F-type (LNB in/loop out), 1x RS-232, 2x RCA audio, 1x composite video, 1x SCART for RGB | ALI3606 8M Geant GN2500 8M 2Tuner V1.07 20120717.16
Missing features: No HDMI (only SD resolution via SCART/composite), no CI (Common Interface) slot for subscription CAMs, no Ethernet. Based on the firmware string, we can infer
