Introduction 1
Revision 1.0 - 7-May-02 HUB24 Series Dimmer Operating Manual
1 Introduction
The JANDS HUB24 is a unique combination of dimmer channels, power distribution
and isolated DMX splitting, all in one compact and low noise package. The HUB24 is
specifically designed for demanding touring and theatre applications and is ideal for
shows where a mixture of conventional and automated lights are used.
Especially suitable for live shows, school auditoriums, trade shows and other similar
applications, the HUB24 eliminates the usual clutter associated with dimmer racks,
power distribution boxes and DMX splitters. The HUB24 also includes the ability to
record and playback snapshots and chases without a lighting console.
One HUB24 incorporates:
– 15 Dimmer outputs
– 9 Power Distribution outputs
– 1 in 2 out opto-isolated DMX splitter
HUB24 dimmers use a chokeless IGBT output topology for reduced weight and low
acoustic noise. The unit is primarily cooled by natural convection; small fans will turn
on only in extreme circumstances.
The unit monitors the supply current drawn on each phase. If more than a preset limit is
drawn from a phase, all the dimmer outputs on that phase are dimmed down until the
current is near to the limit. This ensures connector and upstream circuit breaker current
ratings are not exceeded for long periods of time.
The HUB24 features microprocessor-based digital control. A menu-driven user
interface, consisting of only two buttons, an encoder wheel and a large graphics LCD,
enables the user to easily monitor and select all the built-in functions.
The user has the ability to soft patch the channels out of sequence, test selected channels
while the remainder of the dimmer stays on-line, download custom dimming curves,
capture or build up to eight non-volatile snapshots and chases.
Other functions provided are dimmer “soft” start, bad (soft) neutral detection,
monitoring supply voltage, current and other working parameters of the unit.
Control signal connection to the HUB24 is via a standard DMX-512 socket located on
the front panel along with DMX through and two opto-isolated DMX outputs. Also
located on the front panel are the dimmer and distribution output sockets. The three
phase power entry and a cable tray are located on the rear panel.
The unit will “wake-up” in the mode it was last programmed to run - an ideal function
for stand alone applications. If no particular mode has been previously defined, the unit
looks for DMX control. The user has the ability to set how the HUB24 will respond if
DMX control is lost, but in all cases the dimmer outputs will turn off if the DMX signal
is not restored within 10 minutes.
The HUB24 range of dimmers have been designed to receive future optional software
upgrades to the operating system, without opening the unit.
The HUB24 is convenient to transport due to its solid carry handles, protective
transportation bag and built-in cable tray for storage of the three phase cable.
An optional wall bracket allows the HUB24 to be wall-mounted and optional hand-rail
mounting brackets allow the HUB24 to be mounted on a catwalk rail.

4 Getting Started
Operating Manual HUB24 Series Dimmer
3 Getting Started
3.1 Positioning the Unit
Correct positioning and adequate ventilation are essential for reliable operation. Ensure
the transportation bag or road case is totally removed before use. The HUB24 must be
upright when in use, with clearances of 100mm behind, 200mm above and 100mm on
each side. The unit’s feet provide air intakes (front, back & 2 sides), these openings
must not be obstructed.
See section 6.2 for wall mounting details. See your Jands distributor for other mounting
options.
3.2 Connecting power
The three phase cable must be completely removed from the cable tray before applying
power to the unit.
The mains supply to the HUB24 dimmers must be protected by upstream circuit
breakers or fuses (see sections 8.2.3 & 8.2.4). If the supply cable is damaged, it must be
replaced with a cable available from JANDS or its service agents.
The power plug must be connected to an appropriately rated socket outlet. The plug’s
retaining lock ring (if present) must be screwed home.
WARNING
DAMAGE MAY OCCUR IF THE RETAINING LOCK RING IS NOT
PROPERLY SECURED.
Ensure adequate mains socket access once the dimmer is installed, to allow for
switching the HUB24 on and off.
Turn on the power and check that the three PHASE indicator LEDs are on. Check the
large display is on and not showing any faults before connecting any loads. If the
PHASE LEDs or the display indicate a fault condition, power down and remedy the
fault before trying again. See section 5.5 regarding phase faults.
3.3 Set DMX start channel
The HUB24’s dimmer outputs respond to 15 DMX channels. The first channel can be
set anywhere from channel 1 to channel 512, the remaining channels will follow in
sequence.
• At the main screen (see section 4.1) press the large button 3 times
(to select
Menu1 DMX Settings1-1 Start Channel ).
• Turn the encoder wheel to change the displayed DMX channel.
• Press the large button (now shown as OK) to save the new start channel.
See section 4.2.2 if the dimmer outputs need to respond to out of sequence DMX
channels.
Getting Started 5
Revision 1.0 - 7-May-02 HUB24 Series Dimmer Operating Manual
3.4 Connecting loads
Power down the HUB24.
Plug in the loads to the Dimmer output sockets. It is recommended that, where practical,
the load on the dimmer outputs be evenly spread across the 15 channels. This will
minimise fan noise and make it harder to overload a single phase.
Ensure the load on each dimmer output is greater than the minimum (see section 5.7).
Plug in the loads to the Distribution output sockets. Each output must not be loaded
beyond the capacity of its socket.
3.5 Connecting DMX-512
The dimmer input signal should conform to the USITT DMX-512 (1990) specification.
See section 8.1 for connector wiring details.
The status of the DMX signal is indicated on the bottom of the display.
The DMX input to the HUB24 dimmers connects to the IN socket on the front panel.
The DMX signal may be daisy-chained to the next dimmer via the THRU socket. If the
THRU socket is not being used see section 4.2.3 for how to terminate the DMX
segment.
The two ISO sockets may be used to start two new fully isolated DMX segments, which
may be required for:
• Isolating DMX segments that run to equipment that is powered from different
supplies.
• Star DMX network topology.
• Amplifying the DMX signal for extremely long cable runs.
• Driving more than the normal maximum of 32 devices from a console.
3.6 Power-up sequence
When powering up, the following sequence should be used:
1. Power up the control desk.
2. Power up any softpatches and/or DMX receivers.
3. Ensure the dimmer RCDs and circuit breakers are switched on.
4. Power up the dimmers last, preferably one at a time starting from the first
dimmer rack in the DMX loop.
This procedure minimises the risk of lamps and fixtures responding to any false DMX
data produced by control desks or ancillary equipment at turn-on (producing the lighting
equivalent of an audio “thump”) and prevents damage to lamps, dimmers, and other
controlled devices.
Use the reverse procedure when powering down.
