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 pro-
tocol. Devices that share the 2.4 GHZ spectrum, including Wi-Fi, are manufactured to efficiently share the spectrum and cause minimal interference. Both ShowLink and Wi-Fi
use "listen before talk" technology to transmit short message packets only when needed to conserve bandwidth. 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 uninterrupted on the new ShowLink channel. If ShowLink goes off-line for
any reason, audio transmission will not be interrupted.
Coverage Area
The coverage area of the access point matches the transmitter's RF 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. Any transmitter within
range of an active access point with available capacity will be automatically con-
trolled by that access point. When multiple access points are used to increase trans-
mitter capacity or to increase coverage range, transmitter control is automatically
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 transmitters that are
within the coverage area. Multiple access points automatically 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, an external power supply may be used.
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 source
supplying 15 V DC ±10% (600 mA).
1. Connect the power source 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 transmit-
ters to a clear channel. Channel agility is able to avoid interference from the following
devices that operate in the 2.4 GHz spectrum:
• Wi-Fi (802.11)
• Cordless phones
• Wireless video
ShowLink Icon
The ShowLink icon appears on the home screens of a linked transmitter and receiver
to indicate that the transmitter is controlled by an access point, enabling ShowLink
control. If the transmitter is beyond the range of the access point, or if the receiver is
off-line, the icon will disappear, indicating a loss of ShowLink control.
