Introduction
Revision 1 - 07 July 1999 Event 4 TECHNICAL MANUAL
1 - 1
1. Introduction
The Event 4 lighting control console is designed for stage, theatre, corporate, and live music applications. It has been designed to control all equipment with a DMX-512 input. New fixture types can be added by modifying the fixture library disk if they are not available on the existing release library.
The console has been designed with the capability for users to upgrade the software without removing the base. This is achieved by inserting a diskette with the new operating system, and selecting the appropriate options in the “boot menu”. The boot menu also provides other functions, including console self tests.
Note that static sensitive devices are used throughout the console, and normal handling precautions should be applied during service. Note also that connections should never be made with the power switched on.
Metric fasteners are used almost exclusively throughout the console. The Event 4 Operating Manual should be consulted for a description of desk
operation. Jands recommends that all service procedures be performed by a Factory Authorised
Service Centre or the Jands Electronics Service Department.

Revision 1 - 07 July 1999 Event 4 TECHNICAL MANUAL
2. Equipment Description
The Event 4 is constructed using a folded steel chassis, covered with a reverse screened lexan. The decorative wooden ends are made from plantation growth native Australian timber mounted on an aluminium former, which provides structural rigidity. The timber also protects the fascia of the floppy disk drive. An additional pair of front to back struts reduce flex and ensure front to back spacing is consistent with the base.
A separate assembly is used to hold the power supply (PSU) and central processor (CPU) cards. This bracket is removable as a complete pre-wired unit. A backpanel vent next to the CPU card is removable from the inside and can be used to fit options.
2.1 Tools
With the exception of the base screws and D connector mounting nuts, metric hardware is used throughout the console. The following tools are recommended:
• 7mm nut driver
• 5mm nut driver
• #1 Posidrive screwdriver
• #2 Posidrive screwdriver
2.2 Disassembly
Access to the console is through the base. To remove the base place the console face down onto soft padding. Using the #2 posidrive screwdriver remove all (and only) the silver screws, leaving the four black screws. The base can then be lifted away.
To remove the PSU/CPU assembly, disconnect all cables to the CPU and PSU, and use the 7mm nut driver to undo:
• three nuts next to the power inlet socket,
• two nuts between the PSU and CPU,
• three nuts between the CPU card and the vent/option panel
Use the posidrive screwdriver to undo:
• two screws that hold the CPU tray to the chassis. The assembly can then be removed by sliding it toward the front until it is clear of the
studs, then lifting it out of the chassis. Note that the CPU card can be removed from the console without removing the
complete assembly. To remove the CPU card from the assembly:
• Remove all connections to the card
• Undo the D connector nuts
• Undo the nine PCB mounting screws
• Slide the CPU card away from the back panel until the D connectors are clear of
the assembly, and lift the CPU away.
Page 8
Circuit Notes 3 - 1
Revision 1 - 07 July 1999 Event 4 TECHNICAL MANUAL
The remaining PCBs may be removed by undoing the relevant screws, however attention should be made to the following points:
• Faders should be pushed to their mid position before their knob is removed.
Failure to do so may result in damaged faders.
• The position of the address jumpers on the Palette and Assign cards should be
noted when they are removed so they can be correctly set during reassembly
2.3 Reassembly
Attention should be paid to the following during reassembly:
• LCDs and their windows should be wiped clean with a lint-free cloth before
assembly.
• Ensure the address jumper on Palette and Assign cards are set correctly. Note all
cards should only ever have one (1) address jumper installed. Refer to section 3.2.1 for further information on the card select jumper settings.
• When fitting the CPU ensure all connectors are properly installed, including the
DMX output connector. Also check that the DMX connector wiring is located within the cutout section of the CPU card.
• The CPU trim procedure should be followed if either the CPU or power supply
have been changed, or if the trim has been inadvertently adjusted. Refer to section
3.1.2.
• Test the console fully before installing the base. This includes the disk drive, desk
lamps, back lights, and DMX outputs.
• Double check all flatcable latch connectors are closed before the base is installed.
• Do not overtighten the base screws.
2.4 Precautions and Installation Notes
The Event 4 should be installed in a position which allows sufficient ventilation around the back panel vents – there should be at least 100mm clear space around the back panel.
The Event 4 has been manufactured to comply with all CE/C-Tick regulations, and uses plated panels to ensure minimal radiation emanates from the chassis. In order to maintain compliance all panels and covers should attached using all screws. All connections should be made using the recommended cable type. All back shells should be connected to the cable shield.

Circuit Notes 3 - 1
Revision 1 - 07 July 1999 Event 4 TECHNICAL MANUAL
3. Circuit Notes
The Event 4 uses a main CPU to provide all processing functions. The CPU communicates with the front panel PCBs via the front panel card bus.
3.1 Processor Card
The major functional blocks are as follows:
Function IC Number
Core CPU IC1-8, IC33, IC30, OSC1 Boot EPROM IC25 FLASH ROM IC11-14 RAM Bank 1 IC16-19 Floppy Disk Drive Controller IC48 DMX output IC53, IC38, IC39, IC50, IC51 MIDI IC48, IC35, IC52 VGA output IC6, IC57-60, IC66 Reset/power fail/RAM power IC15 Real time clock IC31 Front Panel Card bus IC9, IC10 Expansion bus IC24, IC26-29
3.1.1 Boot ROM, FLASH, and RAM
The CPU memory consists of a Boot EPROM (IC25), four FLASH ROMs (IC11, IC12, IC13, IC14), and four static RAMs (IC16-19).
The CPU card has the capacity to be fitted with a maximum of 2MBytes program memory (four x 29F040 devices) and 2MBytes show memory (four x 512Kbyte devices).
Only AMD brand 29F040 FLASH devices should be used with boot software versions up to 0.5.
3.1.2 Trim procedure
The adjustment trim on the CPU card adjusts the point where the CPU is informed that power is failing. If a console is dropping its memory, trimpot T1 may be out of adjustment and should be adjusted as follows:
1. Save any necessary console information to diskette
2. Turn T1 fully anticlockwise
3. Place a shunt across J1
4. Switch console on and wait until it has completely started up
5. Slowly adjust T1 until LED L3 lights
Page 10
Circuit Notes 3 - 1
Revision 1 - 07 July 1999 Event 4 TECHNICAL MANUAL
6. Switch off console.
7. Remove shunt across J1 This procedure should be performed whenever either a new CPU or PSU is installed.
3.1.3 Battery
The lithium battery should last approximately 5 years from the date the battery was made - note that a 4 year life from date of product sale would not be unex pected when
delivery and manufacturing times are allowed for. The battery should be considered flat if its terminal voltage measures below 2.9 volts. Backup any required show data to diskette before the battery is replaced.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the battery manufacturer. Dispose of used batteries according to the battery manufacturer’s
instructions.
3.1.4 Logic
The logic requirements for the board are contained in two logic devices, IC33 and IC53. These are in circuit programmable, and are programmed by connecting an appropriate header to CONN3. If it is necessary to reprogram these devices in the field, follow the instructions supplied with the kit.
3.1.5 Desk Lamp Dimmer
The desk lamp dimmer circuit consists of a PWM switching circuit protected by a PTC polyswitch. The polyswitch will trip under overload conditions – when it does LED L6 will extinguish. Due to the nature of the polyswitch it is necessary to either disconnect all desk lamps or switch the console off for approximately one minute in order for it to reset.
3.1.6 DMX Outputs
The DMX outputs are not opto-isolated, however a protection network decouples the driver ICs from high voltages which may be applied during external mains faults. After a fault has been removed these devices take approximately one minute to reset, and during this time the output cables should be disconnected or the console switched off.
3.1.7 Keyboard
The console is protected against excessive load current through the keyboard connector by a polyswitch. After a fault has been removed this device takes approximately one minute to reset, and during this time the keyboard should be disconnected or the console switched off.

Circuit Notes 3 - 1
Revision 1 - 07 July 1999 Event 4 TECHNICAL MANUAL
3.1.8 Expansion Bus
The expansion bus is provided to allow for options to be added in the future. The expansion bus is a buffered extension of the system CPU bus. It is not compatible with Jandshog, Event, or ESP2 type expansion bus option panels, and they should not ever be installed.
3.2 Front Panel Cards
All front panel cards follow a design similar to that of other Jands consoles. A multiplexed 8 bit data/address bus is used to exchange bytes of information between the CPU and the front panel cards. The pin connections however are not compatible and under no circumstances should Event, ESP2, and Jandshog type front panel circuit boards ever be connected to an Event 4 CPU card. Damage will result.
3.2.1 Card Select Jumpers
A jumper on each Preset and Assign card selects the address of the card in the system. When installing new cards ensure that the replacement card has its jumper in the same position as the card it is replacing.
The correct jumper position for a Preset or Assign card is equal to its position from the left eg. the left most Preset and Assign cards have their jumpers set to 0, the next have it set to 1, etc. Master and Palette cards have no address jumper.
3.2.2 LCDs
The character LCD modules use a single backlight driver circuit to deliver the high voltage required for all of the electroluminescent (EL) backlights. This is the function of the EL driver board, mounted near the power supply. This board receives its power and an analogue control from the CPU card.
Note that intensity of the character LCD backlights reduces with age. This is normal and to minimise the reduction the backlights are deactivated if the console hasn’t been used for a preset time. The backlights are immediately reactivated when any front panel button is pressed.

Maintenance 7 - 1
Revision 1 - 07 July 1999 Event 4 TECHNICAL MANUAL
7. Maintenance
If a console should start to misbehave or operate erratically, the problems encountered can usually be attributed to one of two causes:
• normal wear and tear, eg. switches failing and becoming intermittent.
• physical abuse, eg. transit damage, spilt drinks, shorted cables.
Parts most likely to wear out in time with normal use include the following:
• switches
• faders
• LCD backlights
• digital encoders
These are generally easy to spot and there is little that can prevent such wear from occurring, however careful use will maximise their life. Almost all parts of the console can be damaged by physical abuse, however there are a number of things that can be done to prevent this kind of damage:
• Cover the console when not in use, eg. before, after and between sets.
• ALWAYS insert a diskette into the floppy disk drive when the console is to be
transported. This prevents damage to the drive mechanism.
• Do not use spare audio lines for DMX cable. If so, there is a danger that the
connector will get plugged in to the wrong signal.
• Do not smoke over the console.
• Do not obstruct the rear ventilation holes.
• When cleaning, do not use solvents and never allow the entry of liquids into the
console. Use only a damp soft cloth for cleaning.
The console operating software is extremely complex. It is recommended that the console be deep cleared at the start of each new tour.
