Chapter 1 Quad Box Panel
Introduction to Quad box connections
Quad box is an MRMC axis box with a Quad card inside, usually used to
drive four stepper motors.
The stepper motors can be of type:
23B
17B
34B
These motors run on a 48V voltage and can increase speed when supplied
with higher voltage. The Quad box can handle 26-36V; for higher voltage
of 48V, a Y cable can be added to supply extra power.
The Quad box has four stepper motor connectors. See Quad box
connector summary on page 2.
Notes on head-controller communication methods
Three types of connections between the head and controller are in
common use in MRMC equipment:
Ethernet: This is the most modern preferred method, and uses
standard Ethernet plugs, cables, hubs, and protocols.
DataLink: This is an MRMC proprietary connection type
based on a modified form of Serial RS232. You can connect
several DataLink devices together in a daisy-chain. DataLink is
robust and dependable and is still the preferred connection
method in environments with high electrical interference that
can cause problems on Ethernet networks.
Serial RS232: This is based on standard computer serial RS232
hardware and protocols.
Although many MRMC devices have built-in hardware for two or three of
the above connection methods, any controller that you use (such as the
MSA-20 Handwheels, LFP, Joystick Controller, or Mini MSA) must be
programmed at the factory for the connection method that you want to
use.

Quad box connector summary
1-4. #1 - #4 identical connectors for any stepper motors, such as PAN
and TILT in the head, track motors, and external Lens Control
Motors. For pin-out information see Stepper motor connector on page
4.
5. POWER 18-36V connector, for power input for the head.
When the power is on, the LED next to the POWER
connector lights up. For pin-out information see Power
18-36 Volts connector on page 4.
6. DATA connector. This is a Serial RS232 connector, for connection to
a controller using a Serial RS232 connection (as an alternative to an
Ethernet connection), and for updating the firmware in the Quad
box. For pin-out information see Serial RS232 connector on page 4.

7. TRIGGER connector, for a bi-directional trigger signal
between the head and camera. When the trigger is
activated the LED next to the TRIGGER connector lights
up. For pin-out information see Trigger connector (trigger
out and in) on page 5.
8. ETHERNET RJ45 connector for controlling the head using an
Ethernet network connection. This Ethernet port is rated at 100
Mbits/sec but can operate at lower speeds of 10 Mbits/sec or less.

Quad box connector pin-out information
Stepper motor connector
The Quad box has four connectors for
stepper motors, typically used for Pan
and Tilt plus two for auxiliary devices
such as a track motor or Lens Control
Motor (LCM).
1. GND
2. 24V
3. 5V
4. Homing Datum
5. Step
6. Direction
Power 18-36 Volts connector
Two-pin DC input for powering the
head.
1. GND
2. +24V
Serial RS232 connector
This is a 5-pin Serial RS232 connector.
For usage see page 2.
1. Boot select
2. Tx (out)
3. Rx (in)

4. +5V
Pin 3 can be trigger input or output
depending on a jumper setting in the
box which is set during manufacture. DSLR applications typically use two
trigger outputs, on pins 2 and 3; one for shutter and one for auto-focus.
Video applications typically use pin 2 for trigger output and pin 3 for
trigger input.
Adding a Quad box in Flair
When a new Turntable, other model mover or motor driven by a Quad
box needs to be added to a Flair system, there is a set of steps that need to
be followed to get this information on the nature of the item into Flair so
the network can detect it and load it on bootup.
Devices are added to the network as nodes identified by their IP address,
and it is possible that there may be duplicated IP addresses which will
need to be handled before this is possible.
The additional Quad box will need to have an Ethernet cable connected
to the Ethernet hub of the Flair system, and be powered.
1. Edit the file C:\Flair\Flair6\Flair.ini. This file is a text file
that you can edit with any text editor such as Notepad, either
directly or by using the Flair menu option Help >View .ini File.
You need to add or edit some lines in the file similar to the following
lines.
*NetworkBoards: 3
*NodeProgram3: Quad6Ether_II.btl
The keywords used in the above table are described below:
*NetworkBoards: This line shows the number of network
boards (nodes) in the system. You need to increase this by one

(1) to cater for the new Quad board. For example, if the
number of network boards was 2 increase it by 1 to make it 3.
*NodeProgram3: For the node that you are assigning the new
board to (node 3 in this case), add a reference to the node
program, or.btl file, that you want Flair to load on that node
when starting up. The .btl file is already supplied with Flair
so you don’t need to copy or download it from elsewhere. For
example, in this the new board is assigned to node 3, the .btl
file will be added to NodeProgram3.
Remember to save the file after you have edited it. When this Flair is
booted, Flair will attempt to load all the boards it has been informed
about in Flair.ini. It may fail to do so until correct connections are
made and correct IP addresses are set.
2. In the Flair menu, click on Setups >Network Setup. The first screen
is the Connection tab.
3. In the pop-up, click on the Find button.
4. In the Find results, find the IP address of the Quad box
(192.168.1.236 in this example – this is normally written on the box
at the factory), and copy it into the node that you assigned to the
Quad (Node 3 in this example):
5. In the Network Setup pop-up, click on the buttons Save and Apply.
