11.1 Frequently Asked Questions
Q. How do the e24V3’s go with a load such as a
mirror balIs. Is there any trickle?
A. No problems. We use a circuit called PTFD
(Pulse Transformer Fired Dimming), which
means that we can control virtually ANY type of
load (Resistive, Inductive, Strobes, Motors, ELV,
etc), without the need for dummy loads. This is
one of the key differences between LSC and
most other brands of dimmers.
Q. Do the dimmers work on HTP or LTP when
the ePlate wall stations are connected.
A. The ePlates work in LTP mode. So if you
activate Memory #3 it takes control. Then if
another user activates Memory #7 and it
contains the same channels saved in memory
#3 then Memory #3 is de-activated.
Each Memory can contain any combinations of
channels, so Memory #1 can turn all the lights
on at full, whereas Memory #2 may only control
the odd channels. This allows the client to have
a very flexible configuration that is powerful,
whilst remaining simple to use.
Q. Can you disable the ePlates so that no one
plays with one while a console is in use?
A. Yes. You can setup a few different
configurations for how DMX and the ePlates
interact. The most common configuration
is “Auto Switch”. In this mode as soon as
the dimmer sees DMX (after the console is
turned on) then the ePlates are disabled, so no
one can 'accidentally' turn the lights on/off whilst
the console is in use. When the console is
turned off there is a preset delay (1-999
seconds) and then the ePlates are re-enabled.
The other modes allow a button on a specified
ePlate/s to be programmed to manually change
between DMX and Memory (architectural) mode.
Q. How do the ePlates connect to the dimmers
and how do the dimmers link to each other? Is it
all your LSCnet?
A. The ePlate wall stations and e24V3 dimmers
all connect in a daisy-chain, just like DMX. We
use Cat5 cable, as it is cheap and easy to
install. This Cat5 cable carries the LSCnet data
and power to the ePlates.
Q. How many ePlate wall stations can I have in
one system?
A. The limit is 65,535 “devices” on a network.
These can be made up of e24V3 dimmers
and/or ePlates. Depending on the physical
distances involved and the quantities of ePlates
and e24V3's you may need data repeaters and
power supply boosters to make it work.
There are two simple rules
1) Data Limit. You can run up to 800m of Cat5
cable and 32 devices before a data repeater is
needed.
2) Power Limit….A single e24V3 dimmer can
provide enough power to run 4 ePlates. If you
need more ePlates then you will need either
another e24V3 dimmer or an LSCnet PSU
booster.
Q. Is there a max cable length for the LSCnet?
A. No. You will need a data repeater every
800m, but there is no limit as to how many
repeaters you run. If you need to cover very long
distances (for example, greater than 2km) then
you can use the LSCnet-ethernet bridge to
convert the LSCnet data into standard TCP-IP
ethernet and then use existing computer
networks (including the internet) to carry the
data.
Q. Can I remotely monitor the status of my
e24V3?
A. Yes. You will need LSC’s “Houston” software.
This is a Windows PC application program that
allows you to remotely monitor and fault report
on all LSCnet enabled equipment on a single
network.
