Installing the Dobby 2.0
Before you can use the Dobby 2.0, it has to be attached to your loom. If your
loom has a mechanical dobby system attached, you have to disassemble
this system first. Please refer to the user manual of the mechanical dobby
and follow the instructions in the reverse order.
Parts included with the Dobby 2.0 are:
1. 1 power cable
2. 1 USB A-B cable (use only this cable)
3. 1 Switch block
4. 2 Threaded ends, with 2 barrel nuts, 6 washers and 4 knurled nuts
5. 1 USB stick with drivers
6. 1 USB to Ethernet adapter
Attaching the Dobby 2.0
Mount the switch block onto the
knife (the slanted metal strip that
takes the activated dobby hooks
down) on the front side of the
loom, as shown. The switch block
should be facing the dobby unit.
Don’t tighten the knurled nuts too
much. You want to be able to
move the block around until it is
properly aligned with the dobby
top sensor –after the dobby is
attached.

2
Insert the barrel nut into the hole
in the side of the middle section.
The slots indicate the direction of
the threaded hole in the nuts.
Make sure these slots are facing
outwards.
Insert the threaded rod into the
hole and screw it into the barrel
nut. Turn the end by hand until it
sits tight.
Slip on a washer, screw a knurled
nut on and tighten it firmly onto
the washer and place a second
washer onto the end.
Repeat this assembly on the other
side.

3
Slide the Dobby 2.0 over the
threaded ends, and fasten it with
the second knurled nut on each
end.
Now you need to check if the
switch block is directly in line with
the top sensors on the Dobby 2.0.
The distance between the switch
block and the Dobby 2.0 sensor
needs to be less than 1 mm. You
can change this distance by
turning the long nut tensioned by
a spring, screwing it in or out.
The easiest way to set the switch
block is to hold the knife down so
the switch block and the sensor
are aligned. Tighten the long nut
to the front of the sensor. Then
turn the nut back two turns. Check
if the distance between the switch
and lower sensor is also correct.
You can change the height of the
switch block on the knife slightly. If
the height is still incorrect you can
move the entire knife up or down,
for this action, see the loom
manual.
Is the block positioned correctly,
tighten the black knurled nuts on
the back of the sensor block.
The Dobby 2.0 comes with a foot
rest. You can use the foot rest for
your left or right foot.

Connecting the main power supply
First make sure the Dobby 2.0 is
switched off by checking the
power switch on the front.
Connect the Dobby 2.0 with the
cable from the power supply. After
that connect the power supply to
the main power supply. The flat
side of the connector should face
the wooden case of the dobby.
Turn on the Dobby 2.0 by the
on/off switch under the screen.
The screen will show “Please
Wait” while the computer starts
up. This will take about one or two
minutes.
Once the Dobby 2.0 has started
up, the status display shows a
number of things:
Wireless Online
Device Offline
Computer Online
‘Wireless online’, means the Wifi
in the Dobby 2.0 is on and online.
‘Device offline’ means the
solenoids are not active.
‘Computer online’ means that the
built-in computer is on and has a
internet connection.
Below the status messages, the
current IP address is shown.

The bottom part of the status
screen has three buttons:
-Show Password: toggles the IP
address shown with the pasword
for the dobby. This password
changes when a factory reset has
been initated.
-Reset: restarts the internal
computer of the dobby. Used
when your dobby becomes
unresponsive.
-Factory Reset: resets the dobby
to a known default state, activates
the internal wireless access point
and forgets the previous used
network. This also generates a
new password for the dobby.
To connect to the Dobby 2.0 built-
in wireless access point you need
its password. Press “Show
Password” on the status screen of
your Dobby 2.0. The IP address
of the Dobby 2.0 will be replaced
with the password. This password
is used for the internal wireless
access point and besides that to
be able to control the web
interface of the dobby.

Connecting your Dobby 2.0
Setting up a connection between your device and the Dobby 2.0 is a two
step process, in which you first setup a direct connection to the build in
access point in the Dobby 2.0. You will be able to configure it and then, in a
second step, connect the dobby to your home network. (if applicable)
The Dobby 2.0 can only be configured from within the Louët interface web
page so doing this first step is mandatory.
The second step is only necessary if you want to be able to use your
controlling device to do other things like browsing the web or listen to
internet radio at the same time as controlling your Dobby 2.0. This is
because a device (laptop, tablet, phone) can only be connected to one
wireless network at a time
First step: connecting your device to the Dobby 2.0
Determing the network name, address and password of the Dobby 2.0.
The built-in access point of the Dobby 2.0 has the network name “LouetWifi”.
This name cannot be changed. The IP address and password can be seen
on the status screen of the Dobby 2.0:
The status screen normally shows
the IP address of the dobby 2.0.
Out of the box and after a Factory
reset, this is 10.42.0.1
Press “Show Password” on the
status screen: The IP address of
the Dobby 2.0 will be replaced with
the password. This password is
used for the internal wireless
access point and besides that to be
able to control the web interface of
the dobby. The password starts with
a capital L, followed by seven
numbers
You need your local network name and password to be able to connect to
the Dobby 2.0 to your local network.
