Single-Wire Hookup
Power over Ethernet (PoE) capability powers the CEN-WAP-ABG-1G through the
LAN wiring, eliminating the need for a separate power supply. A Category 5 (CAT5)
cable simply connects the wireless access point to a PoE injector (PWE-4803RU),
allowing for installation at a convenient location apart from the access point.
Alternatively, using the Crestron five-port PoE switch (CEN-SW-POE-5), up to four
access points can be powered from a single location, simplifying design and wiring.
A third-party PoE source device can also be used to power the access point.

802.11a/b/g Wireless Access Point Crestron CEN-WAP-ABG-1G
No Configuration Required
Using the CEN-WAP-ABG-1G, a secure Wi-Fi touchpanel connection can be made
quickly and easily right out of the box. Each wireless access point ships with a
unique network name and network key printed on a removable sticker on the front of
the unit. Entering this information into the touchpanel is all that is required to
complete the connection. Multiple access points can be installed in the same vicinity
without causing any connection problems.
Web-Browser Configuration and Management
For applications that require a customized configuration, the CEN-WAP-ABG-1G
features built-in browser-based management tools. From any Web browser, the easy
setup wizard lets you simply select the scenario, such as a standalone network or a
high-security environment, and applies the necessary configuration settings for you.
After configuration using the setup wizard is completed, step-by-step instructions are
then provided for connecting Crestron Wi-Fi touchpanels to the network. Beyond the
wizard, there are more comprehensive configuration and security settings available
for advanced users and system administrators.
Enterprise Level Security
For a secure wireless network in the home or office, the CEN-WAP-ABG-1G
supports up to 152-bit WEP encryption as well as more advanced WPA and WPA2
authentication and encryption methods. RADIUS certificates are also supported for a
true enterprise level solution.
DHCP Server
The CEN-WAP-ABG-1G can assign IP addresses automatically to touchpanels and
other client devices using DHCP (Dynamic Host Configuration Protocol).
MAC Address Filtering
Unauthorized devices can be prevented from joining the wireless network,
maximizing bandwidth for control and streaming AV signals to support only the
touchpanels, computers, and other devices that you specify. MAC filtering increases
security without switching to an authentication method with more overhead.
Event Logging
To assist in troubleshooting, the CEN-WAP-ABG-1G keeps a history of the last 500
client connections, disconnections, and failure events, and includes helpful details
such as the reason for a disconnect or failure.
Bridge Mode
This useful feature allows a CEN-WAP-ABG-1G to be used to add wireless
connectivity to any device with an Ethernet port, or to extend a LAN via a wireless
link whenever a CAT5 wire cannot be run.
Ethernet Pass-Through
An Ethernet port is available on the front of the CEN-WAP-ABG-1G, providing a
convenient LAN connection for computers and touchpanels. This port can be
disabled via software if not required.

of 54 Mbps and an operating frequency of 2.4 GHz.
• 11 B/G Mixed: (Default setting) Specifies both 802.11b and 802.11g.
NOTE: The presence of a single 802.11b client device forces all devices to
operate using 802.11b instead of 802.11g.
• 11A: Specifies 802.11a, which allows a maximum data transfer rate of
54 Mbps and an operating frequency of 5 GHz.
Channel number: From the drop-down list, do either of the following:
• Select Auto to allow the access point to automatically select an RF channel
based on other channels already in use. The access point looks at nearby
access points in the channel range 1-11 and selects the first available
channel that has no other networks present.
• Select the appropriate RF channel for your wireless network. Channel
numbers range from 1 (2.412 GHz) (default setting) to 11 (2.462 GHz).
NOTE: The number of available RF channels depends on local
regulations.
NOTE: To avoid one access point from interfering with others in range, set
the channel number of the access points to different channels. In 802.11b
networks, use channels 1, 6, and 11 to ensure enough frequency separation
to avoid conflicts. For additional information, refer to the latest version of
the Best Practices for Installation and Setup of Crestron RF Products
Reference Guide (Doc. 6689), which is available for download from the

Configuring Advanced
Wireless Settings
To configure advanced wireless settings, click the WIRELESS tab and then click the
ADVANCED subtab. The “Advanced” page opens.
“Advanced” Page
Refer to the configuration guidelines that follow.
Frag. Threshold (byte): In the text box, enter the maximum number of bytes a data
packet must be before breaking into smaller pieces (fragmenting) and transmitting
over the network. The default setting is 2346.
NOTE: The recommended setting is 2346 bytes (default). A smaller setting creates
smaller packets and therefore more packets for each transmission. In areas, however,
where wireless communication is poor or a great deal of radio interference occurs,
you may lower the setting to about 500 bytes.
NOTE: Whenever you change the default setting, it is recommended that you
perform range and reconnection testing.
RTS Threshold (byte): In the text box, enter the maximum number of bytes a data
packet must be before the access point can issue a request to send (RTS). The default
setting is 2346.

Page 33
Crestron CEN-WAP-ABG-1G 802.11a/b/g Wireless Access Point
NOTE: A low value causes RTS packets to be sent more often, consuming more of
the available bandwidth and therefore reducing the apparent throughput of the
network packet. The more packets that are sent, however, the quicker the access
point can recover from interference or collisions.
If several touchpanels are connected to a single access point, lowering the RTS
threshold to a value ranging from 500 to 1000 may improve performance. Assigning
a dedicated access point to each touchpanel improves the performance more.
Beacon Interval (ms): In the text box, enter the desired number of milliseconds
between beacon transmissions. The access point transmits beacons to let the wireless
clients know its name and information. The default setting is 100.
NOTE: By increasing the beacon interval, you reduce the number of beacons and
associated overhead. Increasing the beacon interval, however, delays the association
and roaming process since devices scanning for available access points may miss the
beacons.
A high value ranging from 250 to 500 milliseconds may improve performance in
areas with high radio interference but can also increase reconnection time.
Decreasing the value below 100 does not improve reconnection time.
