<h2 id="body">Commands and responses</h2>
|
||||||
|
<p>Response packets of this format include a source address, which should match the destination in the request. The
|
||||||
|
sequence number of both the request and response should be the same (? todo: verify this), and should be modulo 32
|
||||||
|
(20<sub>h</sub>).</p>
|
||||||
|
<p>While the packet format would suggest it supports multiple commands, I have never observed more than a single command
|
||||||
|
per packet. Response packets include the command number between their packet status and report status bytes.

<h1>JAMMA Video Standard</h1>

<a href="{{ROOT}}/static/JVST_VER3.pdf">A copy of the JVS standard can be found here</a>. The astute reader may observe
|
||||||
|
it is in Japanese. A rather excelent translation can be <a href="http://daifukkat.su/files/jvs_wip.pdf">found here</a>.

|
||||||
|
<p>JVS is a communication standard designed for I/O devices in arcade macines. It typically operates over RS485 serial,
|
||||||
|
however the framing format can and sometimes is used outside of this context.</p>
|
||||||
|
<p>This page documents the canonical JVS structure. Some devices, notably the {{ part("838-14971")|safe }}, use a slight
|
||||||
|
variant on the format. <a href="./comio.html">The differences between the two formats are document here</a>.

<h2>Escaping</h2>
|
||||||
|
<p>Every packet sent begins with the <mark>SYNC</mark> byte, <code>0xe0</code>. Read buffers should be continually
|
||||||
|
flushed until this
|
||||||
|
byte is observed.</p>
|
||||||
|
<p>As such, <code>0xe0</code> is reserved, and is escaped. A byte is escaped using <mark>MARK</mark>, <code>0xd0</code>,
|
||||||
|
followed by
|
||||||
|
the byte's value subtract one. While any byte can be escaped, the only two that require escaping are
|
||||||
|
<mark>SYNC</mark> and <mark>MARK</mark>, escaped as <code>D0 DF</code> and <code>D0 CF</code> respectively. All
|
||||||
|
operations on packets, such as checksums and length calculation, are performed on the <b>unescaped</b> packet.

<p><mark>SUM</mark> is calculated by summing all bytes in the packet, excluding <mark>SYNC</mark> and <mark>SUM</mark>
|

|
itself. <code>n</code> indicates the number of bytes succeeding itself. Due to the existance of the checksum,
|
||||||
|
<code>n=0</code> is nonsensical.

<h2 id="body">Commands and responses</h2>
|
||||||
|
<p>A request packet may contain multiple commands within it. <code>D<sub>0</sub></code> always contains the first
|
||||||
|
command. It is followed by <code>m</code> bytes of data, typically a constant number per command but not always (see
|
||||||
|
the command reference), at which point either we have consumed <code>n-1</code> bytes and the next byte is
|
||||||
|
<mark>SUM</mark>, or the next byte is another command and we repeat.
|
||||||
|

<p>Response packets are structured similarly, however the <mark>CMD</mark> byte is not present, instead relying on the
|
||||||
|
response to be ordered exactly the same as the request. The data of each command is preceeded by a report code,
|
||||||
|
indicating that individual command's status. The below diagram also includes the entire-packet status byte too for
|
||||||
|
clarity.</p>
