Submodules

Decoder

TBC2 has two input decoder submodules. Each supports Component (YPbPr/RGsB), Composite (CVBS) and S-Video (YC) inputs. With the addition of the VGA/SCART expander, it supports VGA (RGBHV) and SCART (CVBS/RGsB) inputs.

Encoder

TBC2 has two output encoder submodules. Each supports Patchable 1V (YRGB) outputs. The output video standard follows the setting of the Genlock Module.

Media

TBC2 has one media submodule. This module is capable of loading still images (JPG, PNG, BMP) from the front MicroSD card socket. The output video standard follows the setting of the Genlock Module.

To use the media module, copy your images into a subfolder of a compatible MicroSD card. For example:

/media/folder/frame1.JPG

We recommend preparing media in a size matching your system's output video standard in JPG or PNG formats. For example, for NTSC video, prepare media at 720 (W) x 486 (H) dimensions.

Always eject or insert your MicroSD card only when your system is powered off. Keep remote backups of any data on your MicroSD card.

The maximum number of images per media folder is determined by the current output video standard, with a minimum of 24 frames in 1920 (W) x 1080 (H) media sizes.

Ramp Generator

TBC2 has one Ramp Generator submodule. The output video standard follows the setting of the Genlock Module. The Ramp Generator is a low speed software renderer designed to generate programmable gradients and other patterns. After any settings change, this module will render a new output frame.

MicroSD Card Compatibility

TBC2 is compatible with some, but not all MicroSD cards. When you acquire a MicroSD card to use with TBC2, we recommend selecting from the specific brands and models we have tested to be hassle free, listed below. Always purchase MicroSD cards from a trusted vendor with name brand packaging to protect yourself against counterfeits. To prepare your MicroSD card for use with TBC2, please format the card as FAT32 with default sector size.

Brand / Series	Size
SanDisk	8GB, 16GB
SanDisk EDGE	8GB

Firmware Update

Download the latest firmware package from the releases section, and unzip the files. Find BOOT.bin and copy it to your MicroSD card.
Power down your TBC2 and insert the MicroSD card.
Power on your system and wait for TBC2 to finish booting, then activate the Update Firmware button on the System page.
Wait for firmware update to complete, until you see the System Restart prompt. Activate the Confirm button to restart your system.
Confirm that your TBC2 boots to the correct version by comparing version numbers on the System Page. Power off / power on your system if you see the wrong version initially.

Factory Reset

To reset your TBC2 firmware to the version shipped from the factory, activate the Reset Firmware button on the System page.
Wait for firmware reset to complete, until you see the System Restart prompt. Activate the Confirm button to restart your system.
Confirm that your TBC2 boots to the factory installed version by comparing version numbers on the System Page. Power off / power on your system if you see the wrong version initially.

Troubleshooting

If the module is receiving power, but the screen is blank, complete the following procedure:

Format a Micro SD card, sized 16gb or smaller.
Copy the current TBC2 firmware (available below) onto the card.
With the module powered off, install the card in the slot in the front of the module.
There are two buttons on the back edge of the module's circuit board. Hold down the top one (labeled "Boot from SD" on early units) and power up the module.
Once the module has powered on, select "update firmware" in the menu and let the module complete that process. Once complete, power cycle the module.
If the issue persists, please make a service request at the bottom of this page.
