5.3 LSC NET CABLING
LSCnet uses Cat5 cable for the interconnection
of devices and all devices are connected in a
daisy chain fashion. All connections are via
industry standard RJ45 connectors.
Cat5 cable daisy chained between devices.
The LSCnet cable is used to carry both data and
power
for the ePlates. LSCnet uses a modified
version of CAN bus, which guarantees that
EVERY command message arrives at it’s
destination, no matter how busy the network
becomes. Architectural systems based on RS-
485 cannot offer this promise, messages can
(and do) get lost, causing the system to miss
important buttons presses.
Each LSCnet enabled product (EKO dimmer,
ePlates, e24 dimmer, TEKO dimmer) is known
as a “device”. Each device has two LSCnet
connectors allowing the Cat5 cable to be looped
from device to device. The EKO can be located
anywhere in the LSCnet network.
The normal rules for data cabling apply.
• You must allow a minimum of 30cm
separation from mains power (or more if
required by local regulations).
• If you must cross over a mains power cable,
always do this at 90 degrees to the power
cable.
• LSCnet cabling must always be a daisy
chain. No Y-splits or T junctions are allowed.
5.4 LSCNET TERMINATION
The LSCnet must be correctly terminated.
Termination is required at BOTH ends of the
data cabling.
• If the LSCnet cable run ends (terminates) at
a device then the termination switch on that
device must be set to TERM.
• If the LSCnet cable run loops through a
device then the termination switch on that
device must be set to UNTERM.
Each ePlate has a main processor board with a
small “LSC Net Connection Board” plugged into
the back of it. This “LSC Net Connection Board”
contains the two network RJ45 connectors and
the “LSCnet TERMINATE SWITCH”.

If an ePlate needs to be removed for service or
testing, the LSC Net Connection Board can be
left in circuit, thus maintaining the network
integrity.
5.5 LSCNET LIMITS
There are limits to the number of devices that
can be powered by the system and limits to the
total length of cable in the network. However,
these limits can be extended by adding power
supply boosters and data repeaters.
5.5.1 Power Limits
The power for the ePlates is supplied from the
EKO dimmer via the Cat5 cable.
A single EKO can power up to 4 ePlates
