A Python library to emulate a Zoom H6 recorder remote control

H6

This library allows you to control your Zoom H6 recorder from your computer using an USB to TTL adapter. For this, you will need a few components to make a specific cable, but it's quite simple.

Cable

You will have to make a specific cable that connects a USB port from your computer to the Zoom H6 remote control port, but fear not. It's actually really simple.

You will need:

• An FTDI USB to TTL converter:

• A 2.5mm jack screw terminal:

• A simple 3 wire cable

All of these components are widely available to buy online and the overall cost is less than 5€.

Once you have all of the components, the wiring is also quite simple:

IMPORTANT: Make sure that the FTDI USB to TTL adapter jumper is set to 3.3v before using the cable. Leaving it at 5v could damage your recorder.

Installation

Simply install the library using pip:

pip install h6

Usage

You can include this library in your Python project or run it directly as a CLI tool.

CLI

To execute commands using your command line run:

h6 -p /dev/cu.usbserial-alcdut1 -c stop

You must specify the serial port using -p or --port and the command to send using -c or --command.

Importing the library

Usage example:

from h6 import ZoomH6
from time import sleep

# Define the serial port
serial_port = '/dev/cu.usbserial-alcdut1'

# Instantiate recorder
recorder = ZoomH6(serial_port)

# Initialize recorder
recorder.initialize()

# Send 'rec' command
recorder.send('record')

# wait for a while
sleep(3)

# Send 'stop' command
recorder.send('stop')

As you can see, when instantiating the ZoomH6 class you will need to specify the serial port where your FTDI USB to TTL adapter is connected.

The initialize() function executes a specific handshake expected by the Zoom H6 recorder in order to accept incoming commands.

You can send any valid command to the recorder. Keep reading for a list with all the available commands.
