Network Cable Run Distance Detail
Devices that operate on IlC’s lightsync CAT-5 , 5e, 6 data line include lightsync switches, photocells, and interfaces like
the lightsync D-6 and sIB-4. A standard CAT-5 , 5e, 6 cable is used for the data line and provides both data and power
to these devices. There are limitations to the distance data can travel over CAT-5 , 5e, 6 cable without loss, and distance
limitations due to voltage drop associated with cable length and number of devices on the lightsync data line. These
limitations are addressed by the addition of a Power supply Repeater, Power supply or lightsync hub (see chart),
depending on the application. The specific use of these devices depends on the project layout.
There are four main areas of limitation to be addressed:
1. Total Data Line Overall Distance:
The total data line end to end distance may not exceed 3000 feet without the
addition of a PsR to the data line. Only a PsR will extend the data line.
2. Total number devices (ILC panels and LightSync devices):
Total number of devices without a PsR is 32.
A PsR will add 31 more devices (PsRs are counted as a device).
3. Total number of LightSync devices powered:
no controller panel can power more than its maximum
lightsync devices on the data line without a Ps, PsR or lightsync hub (each can power up to 20 additional
lightsync devices).
4. Total Power Cumulative Distance:
The cumulative distance from each device to its power supply may not exceed
2000 feet if powered by a IlC panel, or 3000 feet if powered by a Ps, PsR or lightsync hub.
ILC Power and Data Repeating Devices
A
Power Supply Repeater
(PsR) is both a power supply and data repeater and its primary purpose is to repeat data and
provide a bridge to another data line capable of 3000 feet end to end. This device also has one incoming and two out-
going RJ45 ports to split the line into two different directions. The PsR also adds power to lightsync devices for an
additional 3000 cumulative feet.
A
Power Supply
(Ps) provides additional power as needed to the lightsync data line. This is the most efficient
option to compensate for voltage drop from multiple lightsync devices on the data line. note that a Ps provides
power only and does not repeat data.
A
LightSync Hub
(hUB) is a device that allows a home run configuration by providing RJ45 ports for up to 20
lightsync devices, supplying power and data up to 1500 feet per each port.
