==Short Introduction==
JVS, or Jamma Video Standard (sometimes even called JAMMA 2), is a specification by a JAMMA special sub-committee consisting of the major arcade game manufacturers. JVS specifies the type of connectors to use for video (HD-15), audio (RCA) and power ([[JST_VL]]), in addition to the communications protocol between the game board and the I/O board. In contrast to (old) JAMMA, JVS concentrates I/O functions in a separate board.
===A note on the USB connectors===
Although USB connectors and cables are used for communication, both the physical signals and the protocol transmitted is completely different and not compatible.

===Sega 838-13683-93===
There is a some confusion as to what this IO board should be called, some refer to it as 'rev.b'.

* No general purpose outputs
* 9 Buttons pr player, with buttons 6-9 via CN3:
1 - 5VDC Out
2 - 5VDC Out

===Sega 838-13683-02===
This is the second IO board with a JAMMA interface Sega made, there is some confusion as to what this is called, but to be precise it's probably best to stick to what the sticker says (838-13683-02). It identifies itself as:
SEGA ENTERPRISES,LTD.;I/O 838-13683D ;Ver1.09;99/11

The operation and pin-out of extra buttons is identical to 838-13683-93, BUT the silkscreen/markings on this version leaves a little to be desired when it comes to clarity. Pin14 is in the top-left corner in the picture below.

==JVS bus detailed mode of operation==
JVS consists of 4 signals:
* RS-485 A
* RS-485 B
* SENSE
* GND

The RS-485 is for data transfer, is shared between all nodes (implying half-duplex) and runs at 115200 baud, while the sense line is point-to-point.

== Arcade Hardware Using JVS ==
* [[Namco system 256]]
* [[Namco System 357]]
* [[Sega NAOMI]]
* [[Sega NAOMI 2]]
* [[Sega TriForce]]
* [[Sega Chihiro]]
* [[Sega Lindbergh]]
* [[Taito Type X]]
* [[Taito Type X²]]
