'''8-pin DIN 45326''' is a round 8-pin connector conforming to the DIN 45326 standard. It was widely used on Japanese and European computers and AV equipment for carrying analog RGB video, composite video, and audio signals.

== Variants ==

There are two main variants of this connector:

{| class="wikitable"
! Variant !! Also Known As !! Pin Layout !! Description
|-
| '''DIN 45326 Type A''' || DIN-8 270° || "C" or horseshoe shape || Pins 6,7 displaced at 45°
|-
| '''DIN 45326 Type B''' || DIN-8 262° || "U" shape || Pins 6,7 displaced at 41°
|}

The two types are '''not interchangeable''' due to different pin spacing. Type A is more common on Japanese equipment.

== Common Applications ==

=== Analog RGB Output (Computers) ===

This connector was the standard RGB output on many Japanese computers including:

* MSX, MSX2, MSX2+, and TurboR computers (Sony, Panasonic, Sanyo, Yamaha, etc.)
* Fujitsu FM series
* NEC PC-8800 series
* Sharp X1 series

=== Multi-Input (AV Equipment) ===

Some monitors and TVs used this connector as a multi-purpose input carrying:
* Composite video
* Stereo audio
* Control signals

For example, the Sony Profeel Pro series (KX-21HV1, KX-27HV1) uses an 8-pin DIN for their "Video 1" multi-input.

== Pinouts ==

Pinouts vary significantly between manufacturers. The "official" MSX pinout (used by Sony, Yamaha, Panasonic, Mitsubishi Japan, Sanyo MSX2/2+) is:

{| class="wikitable"
! Pin !! Signal !! Description
|-
| 1 || GND || Ground
|-
| 2 || AUDIO || Audio output
|-
| 3 || AV || AV Control (+4.5V to +5V)
|-
| 4 || SYNC || Composite sync (0.3Vpp) or CVBS
|-
| 5 || YS || Fast switch (+3V or +5V)
|-
| 6 || R || Red signal (0.7Vpp, 75Ω)
|-
| 7 || G || Green signal (0.7Vpp, 75Ω)
|-
| 8 || B || Blue signal (0.7Vpp, 75Ω)
|}

'''Note:''' Other manufacturers (Hitachi, Daewoo, Philips, Canon, Sanyo MSX1, etc.) use completely different pinouts. Always verify the specific pinout for your equipment before making cables.

== Comparison with EIAJ-8 ==

{| class="wikitable"
! Feature !! 8-pin DIN 45326 !! [[EIAJ-8]]
|-
| Shape || Round || Rectangular
|-
| Primary use || Analog RGB output || Digital RGB input
|-
| Signal type || Analog (0.7Vpp) || TTL (0V/5V)
|-
| Common on || Computers (output) || Monitors (input)
|}
