Toneburst, DiSEqC and Astra + Hotbird
DiSEqC selects the signal path through the satellite cable. A satellite name in the service list cannot select an external switch on its own. The receiver needs a mapping between each port and LNB.
Configure Astra and Hotbird
Section titled “Configure Astra and Hotbird”- Open Menu → Setup → Tuners, Scanning & Reception → Tuner Configuration → the connected satellite tuner.
- Choose Configuration mode: Simple.
- Choose Mode: DiSEqC A/B for a suitable two-input switch.
- Assign Astra 19.2°E to A and Hotbird 13.0°E to B if the cables use those ports.
- Leave voltage and 22 kHz enabled for a conventional universal-LNB system. Save, check and scan each position separately.
A monoblock combines the LNBs and switch in one housing. Whether Astra is A or B depends on the product and mounting. Both LNBs on a multi-feed dish must be aligned to the intended positions.
Simple modes and their purpose
Section titled “Simple modes and their purpose”| Mode / option | Purpose |
|---|---|
| Single | One LNB/position on a conventional feed |
| Send DiSEqC in Single mode | Yes if a multiswitch specifically requires a port-A command; normally No for a direct LNB |
| Toneburst A/B | Simple two-way switching signal for a compatible switch; also called Mini-DiSEqC |
| DiSEqC A/B | Digital port command for two inputs |
| DiSEqC A/B/C/D | Up to four directly selected inputs; set unused ports to Nothing connected |
| Set voltage and 22 kHz | Selects polarisation and band on a universal LNB; does not amplify the signal |
| Send DiSEqC only on satellite change | Avoids resending the port command within one position; check normal per-zap commands if switching is unreliable |
| Use circular LNB | Only for actual circular reception equipment, not an ordinary linear Astra/Hotbird Ku LNB |
| Positioner / satellite group | Motorised installation; see the motor chapter |
1.0, 1.1 and 1.2
Section titled “1.0, 1.1 and 1.2”DiSEqC 1.0 uses committed commands for up to four switch positions. 1.1 adds uncommitted switches for larger or cascaded installations. 1.2 controls motor positions. USALS calculates motor targets from the location and satellite position. Higher numbers do not mean better picture quality. Cascades require matching command order, port numbers and repeats: advanced settings.
If only one position works, check the port mapping and switch output, then test a known frequency on the other position before changing repeats. AutoDiSEqC can identify supported positions but cannot correct the wiring.
