RGB (8-pin DIN 45326)
This page was last modified 03:42, 7 April 2018 by Grauw. Based on work by Gdx and Wernerkai and others.

Here is the description of RGB output for all MSX systems that use a DIN connector.

The RGB output connector used on MSX is generally DIN 45326 with 8-pin. There are two versions of this connector:

  • DIN 45326 type 8A, with pins 6,7 displaced at 45°, also called DIN 8 270°
  • DIN 45326 type 8B, with pins 6,7 displaced at 41°, also called DIN 8 262°

Type A has its pins laid out like a "C", or horseshoe. Type B pins instead has more the form of a "U" (See picture).

Unfortunately the differences do not end there, as the pin-out also varies. Look for the relevant vendor or system below to see which pin-out and DIN type it uses.

5 R Red signal To SCART pin 15
6 AUDIO Audio To SCART pin 6
7 G Green signal To SCART pin 11
8 AV Slow switch To SCART pin 8


Daewoo CPC-300, CPC-300E, CPC-400, CPC-400S and Mitsubishi ML-F80 (AZERTY)

These computers use DIN 45326 type A. The pinout is described in the following table.

Pin Name Description SCART Connection
1 AUDIO Audio To SCART pin 6
2 GND Ground To all SCART ground pins

Fujitsu FM-X, Pioneer PX-7, Pioneer PX-V7 and Pioneer PX-V60

These computers use a DIN 45326 type A as other MSX but signals are Digital RGB output (D8A), an old Japanese standard. If you use this connector only 8 colors can be displayed. The pinout is described in the following table.

Pin Name Description
1 VCC +12V (FM-X) / N.C. (Palcom)
2 GND Ground
3 I N.C.
4
HSync
Horizontal synchronisation
5
VSync
Vertical synchronisation
6 R Red signal
7 G Green signal
8 B Blue signal


Monitors that support digital RGB are rare. If you still want to use the RGB output, try the diagram below to make an adapter to RGB21. It is based on this diagram. (Not tested, the diagram is probably adaptable for the SCART.)
