ShowLink Basics
ShowLink Channels and 2.4 GHz Spectrum
ShowLink channels that enable remote control of Axient transmitters operate in the 2.40 to 2.484 GHz portion of the RF spectrum in accordance with the
IEEE 802.15.4 protocol. Devices that share the 2.4 GHz spectrum, including Wi-Fi, are manufactured to efficiently share the spectrum and cause mini-
mal interference. Both ShowLink and Wi-Fi use "listen before talk" technology to transmit short message packets only when needed to conserve band-
width. Available spectrum, low interference, and global availability make the 2.4 GHz spectrum an ideal choice for hosting ShowLink channels.
Within the 2.4 GHz spectrum, 16 channels are available for ShowLink communication. To ensure reliable communication, the access point contains an
internal scanning radio that analyzes the 2.4 GHz spectrum hundreds of times per second. If interference is detected, the access point uses channel
agility to automatically switch to a clear channel within the spectrum. All transmitters associated with the access point will continue to communicate unin-
terrupted on the new ShowLink channel. If ShowLink goes offline for any reason, audio transmission will not be interrupted.
Coverage Area
The coverage area of the access point is approximately the same as the
transmitter's range. Use the ShowLink Test feature in the receiver menu
to map the boundaries of the coverage area. Multiple access points can
be used to increase the coverage area or to expand coverage to multiple
rooms.
Transmitter Capacity
A single access point supports up to 16 Axient transmitters, including both
Axient and Axient Digital models. Any transmitter within range of an active
access point with available capacity will be automatically controlled by that
access point. When multiple access points are used to increase transmit-
ter capacity or to increase coverage area, transmitter control is automati-
cally divided between each access point. All changes in control between
access points occur seamlessly and automatically, without requiring user
intervention.
Transmitter Control
An access point with available capacity will automatically control linked
transmitters that are within the coverage area. Multiple access points auto-
matically self-manage to divide transmitter control and maintain coverage.
Transitions between access point control do not affect the transmission of
the audio channel.
Power
The access point is powered through Power Over Ethernet (PoE)-enabled network ports. If PoE is not available, use an external power supply.
Power Over Ethernet
The Shure Ethernet switch and Axient rack components offer network ports
with Power over Ethernet (PoE). The network port powers the access point as
long as the host component is powered on.
1. Insert a Cat 5 Ethernet cable into the Ethernet port located on the body of
the access point.
2. The Ethernet PoE connection supplies power for the access point.
External Power Supply (Optional)
If Power over Ethernet (PoE) is not available, power the access point using
an external power supply.
1. Connect the power supply to the external power supply jack.
2. Tighten the locking ring to secure the plug.
3. Plug the power supply AC line cord into an AC power source.
4. Connect a Cat 5 Ethernet cable to the access point to provide a network
connection.
2.4 GHz Channel Agility to Avoid Interference
When interference is present from Wi-Fi or other devices sharing the
spectrum, built-in channel agility automatically switches the access point
and all controlled transmitters to a clear channel. Channel agility is able
to avoid interference from most devices that operate in the 2.4 GHz spec-
trum, such as Wi-Fi or cell phones.
ShowLink Icon
The ShowLink icon appears on the home screens of a linked transmitter
and receiver to indicate that the transmitter is within range of an access
point making remote control possible. If the transmitter is beyond the
range of the access point, or if the receiver is offline, the icon will disap-
pear, indicating a loss of ShowLink control.
