eBUS port (see figure 14,
— eBUS is a technology (proprietary bus architecture and serial communication
protocol) developed by Extron. It allows many eBUS devices (such as button panels)
and accessories (including power and signal hubs) to be connected to a single
control processor to expand the capabilities of a control system. Button panels are
automatically recognized by the host control processor and can be added or removed
at any time.
See the eBUS Technology Reference Guide (part 68-1499-01) before you install eBUS
devices and accessories. It explains how to determine how many devices are supported
when directly connected to the control processor and where (at what distances and
what points in a system) and when it is advisable to add external power supplies. Also
see the guide for each eBUS device for detailed installation information specific to each
product, such as how to set the eBUS address and mount the devices. Each device in
a system must have a distinct eBUS address that is not shared with any other device in
the same system.
Wire both ends the same on each cable that connects eBUS devices. Extron STP 20
Series cable is recommended for these connections (see the
diagram on page 23).
eBUS Link LED (green)
Lights steadily and remains lit
when the unit detects connected
eBUS devices, there are no ID
con icts, and eBUS rmware is
not currently being synchronized.
eBUS Busy LED (amber)
Blinks while eBUS rmware is
being synchronized.
Blinks if the unit detects an
eBUS ID con ict.
eBUS Accessory Port
Connect the rst eBUS device to this port, then connect
other eBUS devices and accessories to that device in
the desired topology (daisy chain, star, or combination).
• Wire the connectors the same at both ends for every
eBUS device.
• See the eBUS Technology Reference Guide for the
recommended distance from the control processor to
the last eBUS device and maximum quantity of
devices per control processor.
• The IPCP Pro can provide power to the button panel
devices.

OVER
eBUS Overload LED
(red)
Lights steadily when the
eBUS port exceeds
maximum threshold
power usage and enters
the fault state.
During this fault state,
eBUS port power is
shut down until the
power usage falls back
below the threshold.
The Over LED remains
lit during the fault state.
eBUS Status LED (green)
LED is not lit — This indicates one of
the following conditions:
• No power is present.
• No eBUS devices are detected.
LED is blinking fast — An eBUS ID
con ict has occurred: two devices
have the same bus ID number.
LED is blinking slowly — A rmware
update is in progress: the control
processor is synchronizing rmware
of the eBUS panel(s).
LED is lit steadily — Power is present with
con rmed communication and there are
no eBUS ID con icts in the entire system.
