AVerMedia's DVB-S Pro (A700) Card

A DVB-S PCI card from AVerMedia.

It is currently unsupported under Linux, however, experimental drivers exist (see below for details).

Note: A hybrid version of the card also exists; see AVerTV DVB-S Hybrid+FM (A700)


Overview/Features

  • DVB-S input; svideo, composite input; IR input

Components Used

Identification

The output of lspci -vvnn reveals:

Making it Work

Firmware

Drivers

The card is currently not supported by LinuxTV. However, development is well under way and experimental support exists.

Patches

These patches are available to use the card. All are based on latest sources from the hg-tree.

Note: You can apply only one (!) of these patches.
  • Enable analog just the analog part of the card: a700_analog_patch
  • Driver from Zzam: Patch can be downloaded from here (take the a700_full_*.diff).
  • Driver from Tino: Patch can be downloaded from here

Driver Development Status

  • Analog part works (Composite, SVideo and audio in)
  • Needed: I2C sniff while tuning with working driver.
  • GPIO setting of windows driver (Detected with regspy):
GPMODE:   0x80040100
GPSTATUS: 0x0655a314 (changing)
  • board init gpio values:
    • Zzam (Pro): a600
    • Eduard (Pro): 2f200
    • Peter (Hybrid+FM): 6da00
  • eeprom content: The only bytes different from 0xff are
    • subvendor/subdevice id at 0x00: 61 14 a1 a7
    • 4 bytes at 0xe0: 00 01 81 af
    • 2 bytes at 0xe4, differing between all cards
    • cf dd (Zzam, Pro)
    • d7 09 (Eduard, Pro)
    • ea b5 (Peter, Hybrid+FM)
    • fe f6 (bvidinli, Hybrid+FM)

GPIO table

List of known GPIOs.

  • GPIO 0-7: Input Parallel TS
  • GPIO 16: Input TS Valid
  • GPIO 19: Input TS Start of Packet
  • GPIO 23: Reset-PIN of demod (Setting it to input seems enough to keep demod out of reset)
  • The two output ports of the DVB-tuner (zl10036) (P0, P1) seem to be unusued.

Sample kernel output

After passing the command modprobe saa7134 i2c_scan=1, the relevant output of from dmesg is as follows:
