minisatip configuration in satip-axe firmware

The idl4k boxes have integrated universal switch matrix for all four inputs. It allows very complex usage. This document tries to explain some special configurations. For simplicity, the input are numbered as 0-3 here, but the physical F-type connector on the box have numering 1-4.

Standard DiseqC timing and setup

Example: '-q ":5-15-0-5-5-0" -d ":*1-0"'

Power

Since build 11, you may control the power on box inputs. If you use '-P 1' option, the inputs will be powered down when no active client is using the minisatip. This behaviour is similar to minisatip implementation in build 10 or bellow.

If you keep the standard behaviour '-P 0', the inputs are powered down when they are not used by any client. There is a delay of 30 seconds before the power is turned off. Depending on the coaxial wiring and used reception components, the independent input power down might affect the signal quality during the power down phase.

Linked inputs

Example1: '-L 0:2,1:3'

Example2: '-L 0:1,0:2,0:3'

The first number means master tuner and the second slave tuner. The tuners in same group (master can have multiple slaves) can use only same combination of source (src=X), band (low/high) and polarization at a time.

Quattro LNB

The quattro LNB can be configured using -Q option for minisatip. All diseqc (AA), voltage and tone setup is executed, so you may eventually connect a multiswitch or quad LNB (it makes sense only with the -Z option).

The -Z option can eventually reduce the used input to 2 filtering the loband (inputs 2,3) or hiband (inputs 0,1) only. For example, 23.5E satellite positions have useable transponders only in hiband. So, it is enough to connect coaxial cable only to input 0 and 1 and use other two inputs for other LNBs (standard way). Note that SAT>IP source number 1 is always handled for the inputs 0 and 1 (to use full 4 tuners for the loband/hiband inputs).

Example: '-Q -Z 1'

box input 0 ---- multiswitch with diseqc AA = 23.5E
box input 1 ---- multiswitch with diseqc AA = 23.5E
box input 2 ----+---- diseqc AA = 28.2E (SAT>IP src=2)
                +---- diseqc AB = 19.2E (SAT>IP src=3)
                +---- diseqc BA = 16E   (SAT>IP src=4)
                \---- diseqc BB = 13E   (SAT<IP src=5)
box input 3 ----+---- diseqc AA = 0.8W  (SAT>IP src=2)
                \---- diseqc AB = 9E    (SAT>IP src=3)

As you can see, all tuners have src=1 (23.5E), tuner 2 has four additional diseqc sources and tuner 3 two additional sources.

Note: This requires build 11 or above of the satip-axe firmware.

Unicable/Unicable II

Example 1: '-u 0:1-1420,1:0-1210,2:2-1680,3:3-2040'

0:1-1420

0 = minisatip/box input (0-3)
1 = unicable slot number (refer to your unicable equipment)
1420 = transpoder frequency for the tuner

Note: 0:1-*1420 means that only 13V (voltage) will be used.

Note2: If you don't specify the adapter as unicable, it can be used to control the standard LNBs/diseqc equipment.

Multiple unicable groups

You may connect multiple unicable LNBs through multiple coaxial wires to the box. In this case, it is necessary to tell which tuners will use which physical input. In this case '-X T1,T2,T3,T4' option should be used wheren you can define the parent inputs for all four tuners like: '-X 0,0,2,2' where two unicable groups are connected to minisatip input 0 and 2.

box input 0 ---+--- wire 1 (unicable group 1)
box input 1 ---/

box input 2 ---+--- wire 2 (unicable group 2)
box input 3 ---/
