You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />

Appears to be the same as the [[TeVii S660]]. It has the same form factor, connectors are in the same location and it uses the ds3000 and dvb_usb_dw2102 modules. Also suffers from the same DiSEqC switching issues as the TeVii one (as of October 2012, a 2013 commit by liplianin mentions a DiSEqC fix so need to retest).

<p>Merbanan: /* Components Used */</p>
<hr />
<div>DVB-S/S2 USB 2.0 box from [[DVBSKy]].<br />
This device and its clone Mystique SaTix S2 V2 USB have a single LNB F-connector port, and include a IR receiver. It's supported by linuxtv as of september 2014. Support in-kernel is expected in Linux kernel 3.18.<br />
<br />
Alternatively, compiling V4L from sources given by the producer [[DVBSky]] also allows it to run. The IR events are forwared not via LIRC but as xevents, but the shipped remote is not fully supported (e.g. the OK key does not produce a xevent).<br />

Appears to be the same as the [[TeVii S660]]. It has the same form factor, connectors are in the same location and it uses the ds3000 and dvb_usb_dw2102 modules. Also suffers from the same DiSEqC switching issues as the TeVii one (as of October 2012, a 2013 commit by liplianin mentions a DiSEqC fix so need to retest).

It uses tuner chip Montage TS2022 instead of TS2020. Kernel module ts2020 has supported that chip since kernel 4.1 but new ID is still not supported. But it is possible to make it work by including the new ID.<br />

* Prepare DVB-T bank for firmware upload<br />
** Write 0x20 to register 0xf0 in T1 bank<br />
** Write 0x03 to register 0xf5 in T1 bank (this most likely set the mcu to reset state)<br />
* Load firmware for demod<br />
** Write all firmware bytes to register 0xf6 to fill the mcu memory<br />
* Start demod firmware<br />
** Write 0x00 to register 0xf5 in T1 bank<br />
* Check parity<br />
** Read register 0xf8 in T1 bank, if byte 5 (0x10) is set the parity check failed.<br />
<br />
=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />
<br />
* Read register 0xFF in T2 bank<br />
<br />

You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />

* Prepare DVB-T bank for firmware upload<br />
** Write 0x20 to register 0xf0 in T1 bank<br />
** Write 0x03 to register 0xf5 in T1 bank (this most likely set the mcu to reset state)<br />
* Load firmware for demod<br />
** Write all firmware bytes to register 0xf6 to fill the mcu memory<br />
* Start demod firmware<br />
** Write 0x00 to register 0xf5 in T1 bank<br />
* Check parity<br />
** Read register 0xf8 in T1 bank, if byte 5 (0x10) is set the parity check failed.<br />
<br />
=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />
<br />
* Read register 0xFF in T2 bank<br />
<br />
The answer should be 0x02.<br />

* Prepare DVB-T bank for firmware upload<br />
** Write 0x20 to register 0xf0 in T1 bank<br />
** Write 0x03 to register 0xf5 in T1 bank (this most likely set the mcu to reset state)<br />
* Load firmware for demod<br />
** Write all firmware bytes to register 0xf6 to fill the mcu memory<br />
* Start demod firmware<br />
** Write 0x00 to register 0xf5 in T1 bank<br />
* Check parity<br />
** Read register 0xf8 in T1 bank, if byte 5 (0x10) is set the parity check failed.<br />
<br />
=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />

=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />

* Prepare DVB-T bank for firmware upload<br />
** Write 0x20 to register 0xf0 in T1 bank<br />
** Write 0x03 to register 0xf5 in T1 bank (this most likely set the mcu to reset state)<br />
* Load firmware for demod<br />
** Write all firmware bytes to register 0xf6 to fill the mcu memory<br />
* Start demod firmware<br />
** Write 0x00 to register 0xf5 in T1 bank<br />
* Check parity<br />
** Read register 0xf8 in T1 bank, if byte 5 (0x10) is set the parity check failed.<br />
<br />
=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />
<br />
* Read register 0xFF in T2 bank<br />
<br />
The answer should be 0x02.<br />

Signal, Carrier, Viterbi, Sync and Lock.<br />
<br />
=== Lock 88473 ===<br />
<br />
==== DVB-C ====<br />
<br />
* Read register 0x85 in C1 bank<br />
* If bit 6 is set then read register 0x89 in C1 bank<br />
* If bit 1 is set then we have lock.<br />
<br />
==== DVB-T ====<br />
<br />
* Read register 0x62 in T1 bank.<br />
* If bit 5 and 7 is set then<br />
* If the low nibble in the result is >8 there is a lock<br />

* Prepare DVB-T bank for firmware upload<br />
** Write 0x20 to register 0xf0 in T1 bank<br />
** Write 0x03 to register 0xf5 in T1 bank (this most likely set the mcu to reset state)<br />
* Load firmware for demod<br />
** Write all firmware bytes to register 0xf6 to fill the mcu memory<br />
* Start demod firmware<br />
** Write 0x00 to register 0xf5 in T1 bank<br />
* Check parity<br />
** Read register 0xf8 in T1 bank, if byte 5 (0x10) is set the parity check failed.<br />
<br />
=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />
<br />
* Read register 0xFF in T2 bank<br />
<br />
The answer should be 0x02.<br />
<br />

Signal, Carrier, Viterbi, Sync and Lock.<br />
<br />
=== Lock 88473 ===<br />
<br />
==== DVB-C ====<br />
<br />
* Read register 0x85 in C1 bank<br />
* If bit 6 is set then read register 0x89 in C1 bank<br />
* If bit 1 is set then we have lock.<br />
<br />
==== DVB-T ====<br />
<br />
* Read register 0x62 in T1 bank.<br />
* If bit 5 and 7 is set then<br />
* If the low nibble in the result is >8 there is a lock<br />
* If the low nibble in the result is >2 there is a signal<br />
<br />
==== DVB-T2 ====<br />
<br />

=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />

* Prepare DVB-T bank for firmware upload<br />
** Write 0x20 to register 0xf0 in T1 bank<br />
** Write 0x03 to register 0xf5 in T1 bank (this most likely set the mcu to reset state)<br />
* Load firmware for demod<br />
** Write all firmware bytes to register 0xf6 to fill the mcu memory<br />
* Start demod firmware<br />
** Write 0x00 to register 0xf5 in T1 bank<br />
* Check parity<br />
** Read register 0xf8 in T1 bank, if byte 5 (0x10) is set the parity check failed.<br />
<br />
=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />
<br />
* Read register 0xFF in T2 bank<br />
<br />
The answer should be 0x02.<br />

<br />
* Write 0x00 to register 0x08 in T2 bank<br />
* Write 0xE1 to register 0xD9 in T1 bank<br />
<br />
==== Parallel TS with variable clock ====<br />
<br />
* Write 0x00 to register 0x08 in T2 bank<br />
* Write 0xE3 to register 0xD9 in T1 bank<br />
<br />
==== Serial TS with variable clock ====<br />
<br />
* Write 0x1D to register 0x08 in T2 bank<br />

=== Lock ===<br />
<br />
==== DVB-T2 ====<br />
<br />
* Read register 0x92 in T2 bank.<br />
* If the low nibble in the result is >12 there is a lock<br />
<br />
==== DVB-T ====<br />
<br />
* Read register 0x7F in T1 bank.<br />
* If the low nibble in the result is >8 there is a lock<br />
<br />
==== DVB-C ====<br />
<br />
* Read register 0x84 in C1 bank.<br />
* If the low nibble in the result is >7 there is a lock<br />
<br />
When lock is detected it means what the demod has:<br />
Signal, Carrier, Viterbi, Sync and Lock.<br />
<br />
=== Lock 88473 ===<br />
<br />
==== DVB-C ====<br />
<br />
* Read register 0x85 in C1 bank<br />

=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />

* Prepare DVB-T bank for firmware upload<br />
** Write 0x20 to register 0xf0 in T1 bank<br />
** Write 0x03 to register 0xf5 in T1 bank (this most likely set the mcu to reset state)<br />
* Load firmware for demod<br />
** Write all firmware bytes to register 0xf6 to fill the mcu memory<br />
* Start demod firmware<br />
** Write 0x00 to register 0xf5 in T1 bank<br />
* Check parity<br />
** Read register 0xf8 in T1 bank, if byte 5 (0x10) is set the parity check failed.<br />
<br />
=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />
<br />
* Read register 0xFF in T2 bank<br />
<br />
The answer should be 0x02.<br />
<br />
=== TS mode ===<br />
<br />
How to set chip ts mode.<br />
<br />
==== Parallel TS with fixed clock ====<br />
<br />
* Write 0x00 to register 0x08 in T2 bank<br />
* Write 0xE1 to register 0xD9 in T1 bank<br />
<br />
==== Parallel TS with variable clock ====<br />
<br />
* Write 0x00 to register 0x08 in T2 bank<br />
* Write 0xE3 to register 0xD9 in T1 bank<br />
<br />
==== Serial TS with variable clock ====<br />
<br />
* Write 0x1D to register 0x08 in T2 bank<br />
* Write 0xE3 to register 0xD9 in T1 bank<br />
<br />
=== Lock ===<br />
<br />
==== DVB-T2 ====<br />
<br />
* Read register 0x92 in T2 bank.<br />
* If the low nibble in the result is >12 there is a lock<br />
<br />
==== DVB-T ====<br />
<br />
* Read register 0x7F in T1 bank.<br />
* If the low nibble in the result is >8 there is a lock<br />
<br />
==== DVB-C ====<br />
<br />
* Read register 0x84 in C1 bank.<br />
* If the low nibble in the result is >7 there is a lock<br />
<br />
When lock is detected it means what the demod has:<br />
Signal, Carrier, Viterbi, Sync and Lock.<br />
<br />
=== Lock 88473 ===<br />
<br />
==== DVB-C ====<br />
<br />
* Read register 0x85 in C1 bank<br />
* If bit 6 is set then read register 0x89 in C1 bank<br />
* If bit 1 is set then we have lock.<br />
<br />
==== DVB-T ====<br />
<br />
* Read register 0x62 in T1 bank.<br />
* If bit 5 and 7 is set then<br />
* If the low nibble in the result is >8 there is a lock<br />
* If the low nibble in the result is >2 there is a signal<br />
<br />
==== DVB-T2 ====<br />
<br />
* Read register 0x8B in T2 bank.<br />
* If bit 6 is set then<br />
* If the low nibble in the result is >12 there is a lock<br />

=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />
<br />

* If the low nibble in the result is >12 there is a lock<br />
<br />
==== DVB-T ====<br />
<br />
* Read register 0x7F in T1 bank.<br />
* If the low nibble in the result is >8 there is a lock<br />
<br />
==== DVB-C ====<br />
<br />
* Read register 0x84 in C1 bank.<br />
* If the low nibble in the result is >7 there is a lock<br />

* Prepare DVB-T bank for firmware upload<br />
** Write 0x20 to register 0xf0 in T1 bank<br />
** Write 0x03 to register 0xf5 in T1 bank (this most likely set the mcu to reset state)<br />
* Load firmware for demod<br />
** Write all firmware bytes to register 0xf6 to fill the mcu memory<br />
* Start demod firmware<br />
** Write 0x00 to register 0xf5 in T1 bank<br />
* Check parity<br />
** Read register 0xf8 in T1 bank, if byte 5 (0x10) is set the parity check failed.<br />
<br />
=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />
<br />
* Read register 0xFF in T2 bank<br />
<br />
The answer should be 0x02.<br />
<br />
=== TS mode ===<br />
<br />
How to set chip ts mode.<br />
<br />
==== Parallel TS with fixed clock ====<br />
<br />
* Write 0x00 to register 0x08 in T2 bank<br />
* Write 0xE1 to register 0xD9 in T1 bank<br />
<br />
==== Parallel TS with variable clock ====<br />
<br />
* Write 0x00 to register 0x08 in T2 bank<br />
* Write 0xE3 to register 0xD9 in T1 bank<br />
<br />
==== Serial TS with variable clock ====<br />
<br />
* Write 0x1D to register 0x08 in T2 bank<br />
* Write 0xE3 to register 0xD9 in T1 bank<br />
<br />
=== Lock ===<br />
<br />
==== DVB-T2 ====<br />
<br />
* Read register 0x92 in T2 bank.<br />
* If the low nibble in the result is >12 there is a lock<br />
<br />
==== DVB-T ====<br />
<br />
* Read register 0x7F in T1 bank.<br />
* If the low nibble in the result is >8 there is a lock<br />
<br />
==== DVB-C ====<br />
<br />
* Read register 0x84 in C1 bank.<br />
* If the low nibble in the result is >7 there is a lock<br />
<br />
When lock is detected it means what the demod has:<br />
Signal, Carrier, Viterbi, Sync and Lock.<br />
<br />

8MHz 0<br />
<br />
* Write the value to register 0x04 in T2 bank<br />
<br />
== Configure demod for signal reception ==<br />
<br />
* Write 0x00 to register 0xFF in T2 bank<br />
* Write 0x66 to register 0x00 in T2 bank<br />
* Write 0x00 to register 0x01 in T2 bank<br />
* Write 0x02 to register 0x02 in T2 bank<br />
* Set the Digital TV Standard<br />
* Set the demod bandwidth<br />
<br />
And depending on the selected standard / bandwidth configuration write one of the following configuration to the demod:<br />

* Prepare DVB-T bank for firmware upload<br />
** Write 0x20 to register 0xf0 in T1 bank<br />
** Write 0x03 to register 0xf5 in T1 bank (this most likely set the mcu to reset state)<br />
* Load firmware for demod<br />
** Write all firmware bytes to register 0xf6 to fill the mcu memory<br />
* Start demod firmware<br />
** Write 0x00 to register 0xf5 in T1 bank<br />
* Check parity<br />
** Read register 0xf8, if byte 5 (0x10) is set the parity check failed.<br />
<br />
=== Demod mcu ===<br />
<br />
You can check if the firmware is running by reading register 0xf5.<br />
<br />
* If bit 0 is 0 it is running<br />
* If bit 0 is 1 it is not running<br />
<br />
You can control the cpu by writing to the 0xf5 register:<br />
<br />
* write 0x03 to stop the cpu<br />
* write 0x00 to start the cpu<br />
<br />
=== Demod probe ===<br />
<br />
* Read register 0xFF in T2 bank<br />
<br />
The answer should be 0x02.<br />
<br />
=== TS mode ===<br />
<br />
How to set chip ts mode.<br />
<br />
==== Parallel TS with fixed clock ====<br />
<br />
* Write 0x00 to register 0x08 in T2 bank<br />
* Write 0xE1 to register 0xD9 in T1 bank<br />
<br />
==== Parallel TS with variable clock ====<br />
<br />
* Write 0x00 to register 0x08 in T2 bank<br />
* Write 0xE3 to register 0xD9 in T1 bank<br />
<br />
==== Serial TS with variable clock ====<br />
<br />
* Write 0x1D to register 0x08 in T2 bank<br />
* Write 0xE3 to register 0xD9 in T1 bank<br />
<br />
=== Setting Digital TV standard ===<br />
<br />
Select the value representing the standard you want from the list.<br />
<br />
DVB-T 2<br />
DVB-T2 3<br />
DVB-C 4<br />
<br />
* Write the value to register 0x03 in T2 bank<br />
<br />
=== Setting demod bandwidth ===<br />
<br />
Select the value representing the bandwidth you want from the list.<br />
<br />
5MHz 3<br />
6MHz 2<br />
7MHz 1<br />
8MHz 0<br />
<br />
* Write the value to register 0x04 in T2 bank<br />
<br />
== Configure demod for signal reception ==<br />
<br />
* Write 0x00 to register 0xFF in T2 bank<br />
* Write 0x66 to register 0x00 in T2 bank<br />
* Write 0x00 to register 0x01 in T2 bank<br />
* Write 0x02 to register 0x02 in T2 bank<br />
* Set the Digital TV Standard<br />
* Set the demod bandwidth<br />
<br />
And depending on the selected standard / bandwidth configuration write one of the following configuration to the demod:<br />

<br />
The NM88472 is a [[DVB-T]]/[[DVB-T2]]/[[DVB-C]] [[demodulator]] chip manufactured by [[Panasonic]].<br />
<br />
=== I2C Adressing ===<br />
<br />
The chips has 3 I2C addresses, one for each demodulator bank:<br />
<br />
8 bit (7 bit)<br />
0x38 (0x1c) - DVB-T2<br />
0x30 (0x18) - DVB-T<br />
0x34 (0x1a) - DVB-C<br />
<br />
<br />
=== Demod Initialization === <br />
<br />
* Write init reg values for all 3 register banks (T2/T and last C)<br />
* Prepare DVB-T bank for firmware upload<br />
** Write 0x20 to register 0xf0 in T bank<br />
** Write 0x03 to register 0xf5 in T bank (this most likely set the mcu to reset state)<br />
* Load firmware for demod<br />
** Write all firmware bytes to register 0xf6 to fill the mcu memory<br />
* Start demod firmware<br />
** Write 0x00 to register 0xf5 in T bank<br />
* Check parity<br />
** Read register 0xf8, if byte 5 (0x10) is set the parity check failed.<br />
<br />
=== Demod probe ===<br />
<br />
* Read register 0xFF in T2 bank<br />
<br />
The answer should be 0x02.<br />
<br />
=== TS mode ===<br />
<br />
How to set chip ts mode.<br />
<br />
==== Parallel TS with fixed clock ====<br />
<br />
* Write 0x00 to register 0x08 in T2 bank<br />
* Write 0xE1 to register 0xD9 in T bank<br />
<br />
==== Parallel TS with variable clock ====<br />
<br />
* Write 0x00 to register 0x08 in T2 bank<br />
* Write 0xE3 to register 0xD9 in T bank<br />
<br />
