Description

JVC Camera Remote Protocol

README

JVC Remote

Usage

For interactive use inkvoke the script like this: python3 -i listen.py then you can call functions as follows: >>>initCam() >>>sendCmd("Autoiris", 0) >>>sendKey("Iris", 127)

Pinout

26pin_studio_10pin_remote_6pin_tally.xls

Es wird nur der Remote Anschluß benötigt. Der Stecker ist ein gewönlicher 6pin Mini-Din (der PS/2 Stecker) Anschluß. Zum Beispiel: http://www.reichelt.de/SE-DIO-M06/3/index.html?&ACTION=3&LA=446&ARTICLE=17457&artnr=SE-DIO+M06

Protokoll

Signallevel: 3.3V Format: 9600baud 1E8 (8 daten, 1 stop-bit, even-parity)

Protocol Flow

Typical Sequence

Startbyte

Speculative interpretation of ACK byte:

0xA0 => transmission understood, everything OK 0xF2 => transmission understood, but Feature not implemented

Data bytes:

4 Byte:

3 Byte:

Bitflags[2] = apply setting Bitflags[1] = request special transmission

Features

This table was taken from cmds.csv wich was made by capturing the init sequence of CCU and CAM. With this handshake all available/unavailable Features should be negotiated.

cmd type

cmd => 3 byte key => 4 byte

setting

hex value for a specific setting (topic) must be treated differently for key and cmd

value

value to be set for the setting

bitfield

currently we are thinking these bits represet specific flags applies only to 3 byte commands; also see the section about 3 byte data

cam response

Response byte sent by the Camera, tells if the requested feature is available in the specific model. The following table was created by listening to communication with a JVC GM-HY251 //TODO: camera model?

topic

human readable representation of the setting-id for example cmd setting 0x07 is understood as gain control

value-representation

human readable representation of the values a setting can have. such as ON, OFF, incremental values, specific operation modes, ...
