1.3 Installing the lamp
Installation
1.4 Lamp alignment
Every time a new lamp is installed in the fixture, it must be aligned with the optical system to ensure optimum even light output from the unit.
1. Install the new lamp (par. 1.3), close the fixture and switch it on
2. Connect the fixture to a lighting console.
3. Point the fixture at a flat surface (if possible white or light colored) at least three metres from the fixture.
4. Set the control channels to obtain a white beam. Then open the IRIS, set the DIMMER fully open, FOCUS correctly and do NOT
project GOBOS or COLORS.
6. Use screws 1, 2 and-3 to align the lamp until an evenly projected light beam is obtained, with no shadows or zones which are
brighter than others.
1.5 Installing /replacing gobos
Metal: After opening the fixture, locate the gobo to be replaced, press delicately downwards (Fig.1) until the spring and the gobo
come out, making sure they don't fall inside the fixture. Install the new gobo (1) as shown (Fig.2), followed by the locking spring
(2).
Dichro: After opening the fixture, locate the gobo to be replaced, press delicately downwards (Fig.1) until the spring, ring and the
gobo come out, making sure they don't fall inside the fixture. Install the new gobo (3) as shown (Fig.2), followed by the ring (4)
and the locking spring (5).

2.0 -Construction of the signal cable
Giotto spot has a DMX 512 input fitted with standard 5-pin XLR connectors. Screened cables in compliance with EIA RS-485 specifications and the following characteristics must be used for connections:
- 2 conductors plus screen
- 120Ohm impedance
- low capacitance
- max. transmission rate 250kBaud.
Cable connections:
1

3
COMMON see illustration, taking care with the screen, which must be connected to Pin 1
DMXDMX+
2
ATTENTION: the screened parts of the cable (sleeve) must NEVER be connected to the system's earth, as this
would cause faulty fixture and controller operation.
Example of connection of the DMX line
DMX Line
DMX Termination
DMX controller
pan
tilt
To avoid the risk of faulty operation, follow these indications:
Maximum cable length: 500 metres
Max. N° of fixtures connected: 32
Cable runs: Avoid running cables alongside power supply lines.
Termination: A 120Ohm resistor between Pins 2 and 3 on the last fixture.
2.1- Construction of the DMX termination
The termination avoids the risk of DMX 512 signals being reflected back along the cable when they reaches the end of the line:
under certain conditions and with certain cable lengths, this could cause them to cancel the original signals.
The termination is prepared by soldering a 120Ohm 1/4 W resistor between pins 2 and 3 of the 5-pin male XLR connector (see
diagram).

Installation
For this connection, use good quality screened coax cable (RG58 50Ohms) to avoid problems with signal transmission and faulty
fixture operation.
Connectors must always be 5-pin XLRs. Refer to the diagram for wiring.

Giotto Spot is equipped with a microcomputer which allows to customize the fixture to suite the type of installation. In fact, it's possible to assign
the start address; obtain information regarding lamp life and fixture operation time; run test programs to check correct fixture operation and customize some parameters.
3.1 Navigating in the menu
When it's switched on, the fixture runs a start-up reset procedure and the display indicates if there's an input signal or not.

3.2 Allocating the first addressed channel
Addr=xxx
In order to receive the commands necessary to operate from a lighting console, each fixture has to be allocated a
start address. This address normally indicates the first channel used (start channel) and can be allocated following
a different criterion from that used to connect the signal line. Giotto uses 33 controls channels, so during allocation, this quantity must be kept in mind to avoid possible overlapping of other fixtures' channels, which would
cause problems with the perfect control of all the available functions. Should it be necessary, it's possible to allocate the same start channel to several fixtures, in this case the fixtures will all follow the same commands, but can't
be controlled separately. To address fixtures correctly, proceed as follows:
1. Connect Giotto Spot to the power supply, wait until it has completed reset operations and “DMX
signal” appears on the display.
2. Use the UP/DOWN keys to find the “Addr” menu
3. Press ENTER to confirm. The message on the display starts to flash.
4. Use the UP/DOWN keys to select the channel required.
5. Press ENTER to confirm.
