Configuring Communication
55 NXD/T-1200V 12" Modero® Video Wall/Flush Mount Touch Panel
Ethernet Communication from the panel can be direct (using an Ethernet cable) or indirect (through the NXA-
PCI80211G AMX Wireless Card (FG2255-04) communicating to a Wireless Access Point (WAP) such as the
NXA-WAP200G). In determining the Ethernet method of communication, the panel will always default first to
the direct Ethernet communication. If no direct connection is detected, the panel will first check to see if there
is an installed wireless interface card and then communicate to the WAP using the Wireless Settings assigned
within the Wireless Settings page. The WAP communication parameters must match those of the pre-installed
wireless interface card installed within the panel.
 Wireless Access Points are the cornerstone of any wireless network. A Wireless Access Point acts
as a bridge between a wired and wireless network. It aggregates the traffic from all the wireless
clients and forwards it down the network to the switch or router. One Wireless Access Point may be
all you need. However, you could need more Wireless Access Points depending on either how large
your installation is, how it is laid out, and how it is constructed.
 Wireless Equivalent Privacy (WEP) Security is a method by which WLANs protect wireless data
streams. A data stream encrypted with WEP can still be intercepted or eavesdropped upon, but the
encryption makes the data unintelligible to the interloper. The strength of WEP is measured by the
length of the key used to encrypt the data. The longer the key, the harder it is to crack.
802.11b implementations provided 40-bit and 104-bit WEP keys. This is known respectively as 64-
bit and 128-bit WEP encryption. 64-bit is generally not regarded as adequate security protection.
Both key lengths are supported by the Modero product line. Whichever level of WEP you use, it's
crucial to use identical settings (CASE SENSITIVE)--the key length, and the key itself-- on all
devices. Only devices with common WEP settings will be able to communicate. Similarly, if one
device has WEP enabled and another doesn't, they won't be able to talk to each other.
Although the calculations required to encrypt data with WEP can impact the performance of your
wireless network, it's generally seen only when running benchmarks, and not large enough to be
noticeable in the course of normal network usage.
Configuring a Wireless Connection
When working with a wireless card, the first step is to configure wireless communication parameters within
the Wireless Settings page. This page only configures the card to communicate to a target WAP (such as the
NXA-WAP200G), it is still necessary to tell the panel which Master it should be communicating with.
This "pointing to a Master" is done via the System Settings page where you configure the IP Address, System
Number and Username/Password information assigned to the target Master.
Step 1: Configuring the Panel’s Wireless IP Settings
The first step to successfully setting up your wireless card is to configure the IP Settings section of the
Wireless Settings page. The section configures the communication parameters from the Modero panel to the
web.
Wireless communication using a DHCP Address
1. Press the Protected Setup button (located on the lower-left of the panel page) to open the Protected Setup
page and display an on-screen keypad.
2. Enter 1988 into the Keypad’s password field and press Done when finished.
3. Press the Wireless Settings button (located on the lower-left) to open the Wireless Settings page.
Wireless communication is set within the IP Settings section of this page (FIG. 59).
4. Toggle the DHCP/Static field (from the IP Settings section) until the choice cycles to DHCP.
This action causes all fields in the IP Settings section (other than Host Name) to be greyed-out.
5. Press the optional Host Name field to open a Keyboard and enter the Host Name information.
If the SSID (Network Name) and WEP fields have not previously been configured, the
Wireless Settings page will not work until the panel is rebooted.
DHCP will register the unique MAC Address (factory assigned) on the panel and
once the communication setup process is complete, assign IP Address, Subnet
Mask, and Gateway values from the DHCP Server.
