Geniatech T230
August T210v2

A combined DVB-C, DVB-T and DVB-T2 USB 2.0 device from Geniatech. It is also known as MyGica T230. It is supported since kernel 3.19. August T210v2 seem to be identical to MyGica T230.

Don't confuse this with Geniatech T220 or T220A that are the earlier models of the same product. The model number is printed on a sticker.\\ Don't confuse with the following model either, the Geniatech T230C, which looks the same but has different hardware (and requires different drivers).


Components Used

The following components are used on the device

  • USB interface: Cypress CY7C68013A-56LTXC
  • Demodulator: Silicon Labs Si2168-B40
  • Tuner: Silicon Labs Si2148-A20 (a few, mostly Geniatech-branded devices) or Si2158-A20 (most devices)

Driver support

Drivers are included in kernel 3.19. They can be built with media_build for older kernels.

si2157 6-0060: downloading firmware from file 'dvb-tuner-si2158-a20-01.fw'

NOTE: This device needs I2C-Mux support in kernel or as kernel module (CONFIG_I2C_MUX).


Firmware for both the demodulator and tuner are necessary. OpenELEC dvb-firmware collection includes firmwares for this device too.

  • dvb-demod-si2168-b40-01.fw
  • dvb-tuner-si2158-a20-01.fw

Place the 2 firmware files in /lib/firmware.

0cba7ce61c1411cbe7f22c0746e24e33  dvb-tuner-si2158-a20-01.fw

IR Remote Control

The supplied remote control is supported by the driver.

Known issues

Some problems with high bitrate DVB-C streams. Applies to certain DVB-C operators.

An Issue with firmware (TBD) can prevent the August T210v2 from working in this case use dvb-demod-si2168-02.fw instead.
