A triva true view based upscaler/video converter board

for retro gaming hardware

overview

GBS control is an improved GBS8200 RGB to VGA converter board, and an

alternative firmware for Tvia Trueview5725 based Upscaler / Video converter

board.

NOTE:

1) This device does not support composite and S-video inputs.

2) HDMI and VGA outputs will not work if connected at the same time. You will

only be allowed to have one connected at a time.

3) If you want to switch the video input signal (when you have more than one

input video source connected into this device), you need to power off the

device first to avoid potentially damaging the device.

FEATURES

1) Almost zero latency.

2) Supports most retro video game consoles.

3) Supports RGBS, RGSB, RGBS SCART, RGBHV, Component and VGA

Inputs.

4) Supports RGBS, VGA, Component and HDMI Outputs.

5) Supports high fidelity audio output.

6) Built in Si5351 stable clock generator.

7) Supports Video image adjustment.

8) Ability to balance the amplitude of the three primary colour signals - R, G, B.

9) Supports upscaling up to 1080p.

10) Supports downscaling to 240p/288p (Only through the Saturn AV

Connector).

11) No synchronization loss switching between 240p/480i, 480i/480p or

288p/576i.

12) Supported resolutions include:

(240p/288p/480i/480p/576i/576p/640p/720p/960p/1024p/1080i/1080p).

13) OLED Screen and WIFI web configuration pages help you make settings

MICRO USB:

The micro-USB port only supports firmware updates and does not supply

power to the device. If you need to update the firmware, please see the

“firmware update” guide on page 14.

RGBS SYNC SELF-LOCKING BUTTON:

When you press down the RGBS Sync Self-locking button the LM1881 chip

will “strip” the sync information from composite video. When the switch is not

pressed down it will bypass the composite signal.

SYNC ON GREEN SELF-LOCKING BUTTON:

When the SYNC ON GREEN BUTTON is pressed down, this device will

accept the VGA, RGBHV, RGSB signals. When the button is not pressed in,

this device will accept the RGBS and Component (YPbPr) signals.

NOTE:

When this button is pressed, this device can extract and use the sync on

green signal, so the RGsB signal (such as the progressive scan mode on

the retro game console) is accepted, but the “SYNC ON GREEN SELF-

LOCK¬ING BUTTON” and the “RGBS SYNC SELF-LOCKING BUTTON”

must be pressed simultaneously.

POWER SELF-LOCKING BUTTON:

When this button is pressed down, this device is POWERED ON.

DC 5V 2A:

Connect a suitable 5V2A, 2.1 x 5.5mm PSU.

HDMI OUTPUT:

Standard 3.5mm stereo headphone plug type connector. Outputs High-

Fidelity audio.

DC 5V 2A:

Outputs a HDMI Digital signal.

RGBS/YPBPR OUTPUT (SATURN A/V CONNECTOR):

If you want to output RGBS (which you

must through the Saturn A/V connector),

you need to slide across the switch to

“RGBHV/RGBS SLIDE SWITCH”. If you

want Component signal output through

the Saturn A/V connector, you also

need to turn on the “RGBHV/Component

Toggle” in the web settings page.

NOTE:

1. The HDMI Slide Switch much be switched to off if you want to output

RGBS/Component signals through the Saturn AV Connector.

2. The GBSC only outputs lower resolutions such as 240p/288p through the

Saturn AV Connector.

VGA OUTPUT:

Standard D-Sub15 (VGA) connector.

NOTE:

If you want to output VGA signals through this interface, The “HDMI SLIDE

SWITCH” must be turned to “OFF”.

HDMI SLIDE SWITCH:

Toggles the HDMI signal OFF and ON.

RGBHV/RGBS SLIDE SWITCH:

If you want to output RGBS signal, please slide this switch to “RGBS” side. In

other cases, please keep RGBHV by default.

NOTE:

This function is used as RGBHV (VGA) to RGBS signal output.

SCART INPUT:

The European standard SCART interface can only receive RGBS signals.

The less common Japanese JP21 SCART must be used with a converter.

VGA INPUT:

Standard D-Sub15 (VGA) connector, accepts the VGA and RGBHV signals.

It can also receive RGsB signals.

NOTE:

If you use this interface, you must press down the switch ”SYNC ON GREEN

SELF-LOCKING BUTTON”.

COMPONENT INPUT:

Accepts the Component (YPBPR) signal.

NOTE:

The “SYNC ON GREEN SELF-LOCKING BUTTON” and “RGBS SYNC

SELF-LOCKING BUTTON” must stay pressed in.

AUDIO INPUT:

Left and right audio input.

182MM

105MM

RGBS INPUT:

Accepts the RGBS Signal. We recommend you press the “RGBS SYNC

SELF-LOCKING BUTTON” down to get a clean sync signal through the

LM1881 chip when using RGBS.

NOTE:

If you are using this input for a progressive scan RGBS signal (normally

480p or 576p), please press down these two switches at the same time. The

“RGBS SYNC SELF-LOCKING BUTTON” and “SYNC ON GREEN SELF-

LOCKING BUTTON”.

RGB KNOB:

Adjust the red, green and blue signals intensity of the output images.

COMPATIBILITY MODE SLIDE SWITCH:

Toggles compatibility mode ON and OFF.

NOTE:

The “Sega 32x/Neo Geo AES” consoles require the compatibility mode slide

switch to be turned ON. For best results restart the GBSC for the changes to

take effect.
