X Po i n t R o u t e r

XPoint™ Router Fixture-Level Digital Control
Information:			An XPoint Router consists of two types of control card:	
	

	

	

			Driver boards are available as:	

a) The XPoint Router Board 	

b) The XPoint Driver Board

a) Relay Drivers 	

b) Dim Drivers

	

XPoint Router
Board:			The router board has a pair of yellow RJ45s for the GR 2400 bus and a pair of white RJ45s for the XPoint bus. The white

RJ45s are considered the XPoint Port and each RJ45 may drive a “String” of up to 2,000 ft. of Cat. 5 wire with up to 64
modules on it. Thus, one could consider the XPoint bus to be 4,000 ft. long with up to 128 modules only driven from the center
of the bus.

Relay Driver
Cards:		
Relay drivers plug into the XPoint Router board and emulate a single GR 2448 relay panel. Up to two driver boards may drive

a single XPoint port giving a maximum of 96 relays/zones emulated. The relays in the XPoint Modules are software assigned to
operate as one of the emulated relays, now called a Zone. One or as more relays from the XPoint Modules on the bus may be
assigned to a zone. Thus, if one wishes to have individual control, one may have up to 96 zones/relays on the bus. It is far more
usual to have about 12 zones of control with all the relays assigned to these zones.	

Dim Driver
Cards: 		Dim drivers also plug into the XPoint Router Board and similarly emulate a GR 2408 iDim or iDH panel. These are only

available with 4 (0–10 volt) dimmers (in a DH card these are relays), 4 scene accessible relays, 4 photosensor inputs and 8
dry contact scene inputs. Each dimmer or relay can be considered as a zone. Dimmers on the bus can be assigned to dimming
zones, relays to relay zones. Up to 4 driver cards can drive a single XPoint port. These can be a mix of both dimmer and relay
drivers. (No more than two relay drivers.) If all four boards are dimmers, there will be 16 available zones of dimming on a single
bus. XPoint Dim and DH modules additionally have a photosensor and a contact closure input on each module. These may be
assigned to any available “soft input” on each of the driver cards through software. Each driver card has 4 “soft” photosensor
inputs and 8 “soft” scene inputs. A single photosensor may be used to control Dim/DHs in all 4 cards. In the same way the
contact closure input can be assigned and can have an occupancy sensor connected that operates scenes in one (or all four)
of the emulated Dim/DH cards. Occupant sensor inputs can be “soft” programmable to be used with pull high or pull low style
sensors. Only one style may be used on a bus. Note: The photosensor and contact closure inputs only operate on relays or
dimmers assigned to Dim/DH cards. They do not work with relays assigned to relay drivers on the same port.

XPoint™ Module Fixture-Level Digital Control
Description:
The XPoint Modules provide all the features of a networked Relay or (0–10V) Dimmer without the panel. Use the XPoint Module to
control an individual fixture, a string of fixtures, a 30A circuit or anything in between. Precise control exactly where you need it.
Daisy chain up to 128 XPoint Modules from a single port on an XPoint Router. Modules are placed on a string of Cat. 5 cable with RJ45
connectors. Routers come with driver boards that emulate either a relay panel or a dimming panel on the GR 2400 system. The XPoint
Modules may be assigned to any one of up to 96 Relay zones and Dimming Modules to any one of up to 16 dimming zones. Program
each zone as required. Reprogramming is as simple as remotely accessing the LC&D GR 2400 system.
Relays are software selectable normally closed (N/C), normally open (N/O), or “Latching” (no change on power failure).
Note: XPoint Modules may only be plugged into an XPoint Router bus port.

Control any standard ballast—ideal for both new construction and retrofits
Fits into a standard 1/2" KO in any fixture or J-box
Each Port from an XPoint router drives two strings of up to 2000 ft, each string supports up to 64 modules
for a total of 128 modules on a router port. (One could think of this as a 4000 ft bus with 128 modules driven
from the center of the bus in order to minimize voltage drop since Modules are powered from the router.)
Up to 128 modules on each port
Dual relay counts as a single module allowing 256 relays per port
Field installed or shipped to fixture manufacturer for factory installation
Dim and DH Modules have inputs for photosensor and occupant sensor (must use specified occupant   
sensor — each sensor reduces modules on bus by 3)
Optional 0–10VDC control for dimmers
Relay defaults to software selectable state at loss of bus power or loss of communication with router
box (N/O, N/C or Latched)

XPoint LT

XPoint™ LT
	

	

Description:	 XPoint LT is a low cost option specifically designed for small scale XPoint projects where 128 or less XPoint modules are needed.  
XPoint LT combines the GR2400 DTC, GR2400 Modem and XPoint router card into one enclosure.  XPoint LT enclosure has
space for one additional accessory card, such as a Link-To Ethernet card.  Standard XPoint router cards cannot be connected
to this system.  If a larger XPoint system is needed, please refer to the standard XPoint system.  XPoint LT is available in two
configurations:

Switching
Configuration:	 The switching version of XPoint LT provides control of up to 128 modules in 96 discrete zones.  Multiple relays can be put into

the same zone.  If each relay must be controlled separately, then 96 relays should not be exceeded.  Applicable XPoint modules
include: XP RL1, XP RL2 and XP RL480 QK.  Please refer to the XPoint module techsheet for details.

Dimming/DLH
Version:	 The dimming version of XPoint LT provides control of up to 128 modules in (8) 0-10V dimming and (8) switching zones.  Multiple
relays can be put into the same zone.  The Dimming/DLH version provides 8 photocell and 16 dry contact groups.  These inputs
can be accessed through the XPoint Dim (XP RL1 DPI) and XPoint DH (XP RL1 PI) modules which have a photocell and a
contact closure input on each module.  These modules will only work with the Dimming/DH XPoint router card.

	
Features:	 • Reconfiguration of zones without rewiring
	
	 •	Single enclosure for DTC, router cards, and interfaces for quick and easy installation
	
	 •	Enclosure includes space for one additional interface card such as: a Link-To Ethernet card, Link-To BAS card or a

Micro Panel™
	Description:	The MicroPanel™ comes standard equipped with four relays (MicroPanel-4) and provides integration features
simply not available anywhere else; particularly the advanced daylight harvesting properties. In its extended
version it is a compact lighting controller with up to eight switching (iDH) and four 0–10V dimming (iDim)
outputs that links every room into one digital, easy-to-use system.
The MicroPanel-8 (with eight relays) provides eight switched outputs, four of which can be dimmed outputs
using a single control card. It is the ideal solution for applications requiring more than four switch legs per
classroom. Example: “a, b, c” lighting with dimming, a leg for presentation lighting over a white board,
emergency lighting, and a contact closure for the thermostat. For applications that require more than four
(0–10V) dimming outputs, a second control card may be added.

The Digital Daylight Harvesting Solution
Because our competitor’s daylight
harvesting controls are not part of a
system, commissioning and any later
adjustments often require on-site or
hardwiring changes.

With proper installation, expensive
on-site commissioning can be eliminated.
Commissioning can be accomplished
remotely (via dial-up or internet) from the
factory.

The MicroPanel-iDH and -iDim solve
this with our 100% digital lighting control
system.

Any adjustments (e.g.,­­­ to adapt to
interior design changes) can be made
with a phone call.

Adjustments can
be made with a
phone call
Unprecedented Daylight Harvesting
Response Curve. Individually set three
points on the response curve, start dim
level, mid-point and turn off or end point.
This is a major breakthrough in daylight
harvesting, as almost any architectural
setting can be compensated for after
photosensor placement.
Fade Rates. Separate raise and lower
fade rates (0 seconds to 100 minutes)
in response to the photosensor helps
accommodate human eye response.
0v

Baseline. If room occupants feel the
automatic settings are too bright or too
dim, they can adjust the baseline with
an optional slider switch. The adjustment
range of the slider can be set remotely.

Time Delay. Prevents
nuisance cycling.  Adjust
from 0 seconds to 99
minutes.

Occupants offered a degree of control are
less likely to disable the system.

Trim. Individual trim
levels may be set for
each dimmer to compensate for
manufacturers’ ballast response (for
example, 2–8V instead of 0–10V).

Multi-Zone Dimming & Switching
The really big news is the ability of
the MicroPanel to control multiple
daylight harvesting zones (dimming or
switching) with a single (local or global)
photosensor.

Each dimmer (or relay) may have its own
dimming curve appropriate to its location
in the room. These multiple dimming
curves are ideal for open loop or closed
loop daylight harvesting.

No matter what the exposure may be
(north, south, east or west), the right
curve can be precisely set for any
architectural setting.

If you have not filled all 42 breaker positions,
you must order the difference in breaker spacers
(BSPC) (example: if a 225A feed current panel had
32 1-pole breakers were specified, then 10 breaker
spacers would be required, or If 20 2-pole breakers
were specified, 2 BSPC would be needed, or for

Breakers and Breaker Accessories

Due to the complexity of this product, breakers
must be entered as separate line items following
the chassis code. Enter quantities as part of the
line entry. One 20A 1P breaker must be reserved
to provide power for control electronics.

1P[amp]ARB = 1-Pole Remote Breaker
2P[amp]ARB = 2-Pole Remote Breaker
1P[amp]ABB = 1-Pole Branch Breaker
2P[amp]ABB = 2-Pole Branch Breaker
3P[amp]ABB = 3-Pole Branch Breaker
BSPC = Breaker Spacer
CLIP = Locking Clips

If you have not filled all 42 breaker positions,
you must order the difference in breaker spacers
(BSPC) (example: if a 225A feed current panel had
32 1-pole breakers were specified, then 10 breaker
spacers would be required, or If 20 2-pole breakers
were specified, 2 BSPC would be needed, or for
12 3-pole breakers, you would need 6).

Where [amp] is, replace with ampere rating for that breaker (please refer to the
Ampere Rating Table to select the proper rating for a specific breaker type).

Panel

The SilverBullet ™
	

Sub-Branch Circuit Current Limiter

Description:	 Lighting calculations for most energy codes include a deduction for each linear foot of track. California’s

Title 24 “charges” 45 watts/linear foot of track lighting. Seattle “charges” 70 watts/foot. ASHRAE, 30
watts/foot. With today’s lighting technology the connected load is far less than the per-foot requirements
of these codes.

		 The SilverBullet, a “Sub-Branch Circuit Current Limiter” solves this requirement by enforcing a definite
current limit to lower the VA rating of each track lighting circuit.
	

	
	

	 For example, California’s Title 24 would require three track circuits with a total length 100 ft to be
calculated at a minimum of 4500 watts (45 watts/foot x 100 ft). With the SilverBullet those three tracks
could be limited to 8 amps each to reduce the lighting load calculation to 2880 watts (120V x 24 amps).

Features:	 •	 Current limiting for up to 21 circuits

	 •	 Current limiting available from 1-8, 10,13 & 15 amps

	

	 •	 Compact Sizes  12" w x 18" h x 4" d or 12″ w x 12″ h x 4″ d

	

	 •	 AIC Rating of 10,000A @ 120VAC

	

	 •	 Factory pre-assembled

	

	 •	 Each load factory labeled on the door sheet

	

	 •	 No programming required

Specifications:
	 Enclosure dimensions:	 12″ w x 12″ h x 4″ d, (1-12 supplementary breakers)
	
	 12″ w x 18″ h x 4″ d, (6-21 supplementary breakers)
	
Enclosure type:	 Surface mount, hinged locking door, NEMA 1
	 Optional enclosures:	 Flush mount
	
Certifications:	 Panel complies with UL 508, breakers comply with UL 489
	
Max. humidity:	 10–90% non-condensing
	 Ambient temperature:	 32–104° F (0–40° C) (Note: Thermal magnetic breakers. De-rate to 80% of load for temperatures over 70° F)

C(3) states:

Track Lighting

This is what the SilverBullet does.
When doing energy calculations, use
the ampere rating of the supplementary
breaker in the SilverBullet as opposed to
the linear footage of the rack. No magic.

SnapLink™ Latching Relay
	Description:	 The SnapLink™ Latching Relay from LC&D is a single-pole, lighting relay designed to meet the

demands of today’s high-efficiency ballast loads. This latching relay can be specified to default to open
(simulated NO) or to default to closed (simulated NC) upon loss of power. The Normally Closed relay is
the default relay shipped unless otherwise noted.

	Features:	 •	 New larger contacts allow switching up to 30 amps lighting (ballast, HID) at 277V, 20 amps at 347V
and 20 amps Tungsten at 120V

	

	 •	 UL listed for 18,000 amps SCCR (Short Circuit Current Rating) at 277V

	

	 •	 Eliminates zero-cross circuitry—ideal for many modern types of ballast, particularly HID which can
become “core-saturated” when controlled by zero-cross lighting relays

	

	 •	 New heavy-duty, high-conductivity terminal blocks allow up to 2 #8 AWG wires per lug

	

	 •	 3-year warranty

	

	 •	 Since relays are latching, no energy is used to hold contacts, creating less heat

DataLogger™
	
	

Description:	 DataLogger™ lighting management software reads and then logs information about the lighting controls
which can be used to better manage a facility. DataLogger offers three different software modules:

	 Runtime Module keeps a log of the total run time of lighting loads. This can be used to schedule lamp
changes and to keep track of lamp life (in hours).	
	

		 The ON event total counts the number of ON events for each relay. This is useful for lamp life
calculations.
	

	 Event Logging Module keeps a log of all events which affect the status of relays, dimmers,
SmartBreakers, and other digital devices. For example: the actual on and off times of relays, which
device or schedule turned a relay or group of relays on/off or how often lighting is extended after
hours.	

	

	 The GR 2400 Digital Bus writes the logs directly to the UpLink™ network multiplex card for each GR 2400
Digital Bus. Logs can be downloaded and managed from a workstation which has installed DataLogger.
A MetaServer™ digital web server acts as the portal to the UpLink Cards and can be accessed over the
local area network or the internet.

	

	 Refer to the UpLink and MetaServer Tech Sheets for more information about these products.

Balanced audio cable will not do.

The Link-To DMX control card converts 14
contiguous DMX channels into 14 global
GR 2400 switch commands. When the
level set to that channel exceeds 90% the
switch sends out an ON command. When
it drops to less than 10% it sends out an
OFF command. See the GR 2400 manual
for switch programming information.

MetaServer™ and UpLink™
	

Description:	

The UpLink™ network multiplex card links up to 99 digital buses together to create a system with over 12 thousand digital lighting
control devices.

	

	 The MetaServer™ digital web server is a gateway that provides Internet or computer access to these devices.

	

	 Here’s how they work: Up to 127 digital addresses (relay panels, digital switches, etc) may be linked together within a GR 2400 digital bus. Except for the largest projects, this proves to be more than enough capacity. For larger installations where multiple buses are
needed to accommodate the large number of digital devices, LC&D has developed a BackBone Bus using the UpLink™ card and
MetaServer™ to link up to 99 GR 2400 buses together.

	

	 At the head of the BackBone Bus is a MetaServer that does the duty of connecting the whole system via Ethernet or Modem to a
computer or the internet. Connecting each digital bus to the BackBone Bus is an UpLink card. It captures packets meant for that
particular bus and routes the data correctly. The UpLink card has a large memory capacity which acts as a mirror of the status of the
GR 2400 bus for more rapid communication. It also keeps logs of the number of times a relay has been operated, the time it has
been ON since last reset and a log of each event (see DataLogger™ tech sheet for more information).

	

Features:	 •	
•	
•	
•	
•	

An almost unlimited number of commands may move from one digital bus to another. Switches from one GR 2400 bus
may control all relays, dimmers, scenes, groups, or SmartBreakers in other downstream busses with full feedback.
Run-time and event-logging are stored in Flash memory until downloaded by an administrator (see tech sheet for
DataLogger software)
Connect as many as 99 UpLink cards to the internet
Access multiple buses using Unity GX Advanced Graphical Software
The MetaServer requires only a single IP and provides complete access to one or multiple buildings

Bus Booster
Description:	 The Bus Booster is used on the GR 2400 System when the distance between switches and a relay panel

	

cause voltage drop.

Switches are supplied with power over the GR 2400 bus.  While the data can travel 4,000 ft., the power to
a switch needs to be fed with a relay panel or a bus booster every few hundred feet.

Features:    •  Provides up to 0.8 amp at 12 volts DC to the system bus
	

	 •  Simply power up and plug in the bus

	

	 •  Current limited
