Introduction
The RetroTINK-2X SCART is the next evolution of the original 2X for converting RGB video
signals from retro consoles to a modern Digital Video display. The 2X-SCART is specifically
designed to handle 240p off-spec signals and output 480p with low latency and minimal
artifacts to preserve the original gaming experience.
The SCART version adds a scanline generator, USB firmware upgrade support and is housed
in an injection molded enclosure. In addition, the 2X-SCART is fabricated on a 4-layer PCB
with improved routing, power supply and filtering for lower video noise.

Quick Start
First insert a microUSB power cable to the device. You may use any source capable of
supplying at least 500 mA.
Second, connect your console to the device via the SCART connector.
Third, connect the device to your display via a Digital Video cable. You should now see the
output from your console on your display.
Finally, press the ‘FITLER’ button until your desired effect is shown. The effect cycles between
normal (blocky), smoothed and scanline effects.
The RetroTINK-2X SCART remembers the filter settings between power cycles.

Firmware Upgrade
The 2X-SCART has the ability to upgrade the firmware over USB using a PC-based
application. No special tools are needed.
Firmware upgrades requires that the 2X be started in bootloader mode. Hold the ‘FILTER’
button down while connecting the 2X to a PCB via USB cable. The LED indicator should
remain solid RED.
If the upgrade process fails, simply restart by powering off the device and re-entering the
bootloader. Since the bootloader resides in a protected region on memory on the
microcontroller, bricking the device is extremely unlikely.
To exit bootloader mode without upgrading, disconnect the microUSB cord from the 2X, then
reinsert without holding the ‘INPUT’ button down.

Troubleshooting
Q: No image is shown.
A: Double check that the 2X is powered up and that the Digital Video cable from the 2X is
securely plugged into your TV. Try another TV and Digital Video cable. Without any console
connected, you should see a colorbar test pattern. If you do not, contact your seller for
additional assistance.
Q: Some consoles work but other consoles show a black screen on the TV
A: Retro-consoles deviate from standard video refresh rates and timing. The 2X is a low-
latency line doubler and thus, does not alter these off-spec timings. It is likely your TV does
not like the output rate of a specific console. Try another TV or monitor.
Q: Picture is noisy and/or interference is seen.
A: In almost every case, the noise originates from the console, console’s power supply and/or
the cables used to connect the console to the 2X. The noise almost never originates from the
2X itself. In addition, to preserve image sharpness, the 2X does minimal filtering to attempt
and smooth out noisy sources. For the best image quality, always use official power supplies
for your console and shielded video cables.
Q: No sound is heard.
A: Double check to make sure the audio cables are connected correctly. Try another TV. The
off-spec video timing of some-retro consoles causes some displays to reject the audio stream
in the Digital Video connection. Alternatively, directly connect the audio output from your
console to your sound system and bypass the 2X.
