Working with a WAP
Zero Wire DMX will work with any off the shelf Wireless Access Point (WAP). Each WAP
comes with its own configuration setup software which should be run according to the
accompanying manual.
However, after connecting to the WAP either wirelessly or via a cable, your PC should be
able to reach the web interface. For the Linksys ® WAP11 the interface should look like this:
Here it can be seen that this WAP has its SSID set to A and its Channel is set to 1. If the
SSID of the boxes are also set to A then the system will work and the encoder box will route
its airborne DMX data via the WAP, if there is any discrepancy it will not work. Please note
the SSID is Case Sensitive.
The Channel is the physical frequency which the WAP operates on. There are different
numbers of channels available in different countries around the world and it is the users
responsibility to check that they are using a legitimate frequency.
The key to the channel concept is that if you change the channel of the WAP then EVERY
device on the same SSID will move channels.
So if you experience data corruption or interference whilst using the Zero Wire DMX system
you can instantly move to a clear channel. This ability to change channels during the show
and ‘on the fly’ is one of the great advantages of the Zero Wire DMX system above other
similar systems and above traditional older wireless systems.
Configuring the WAP
The WAP should only ever need three parameters changing, these are the IP address, the
SSID and the Channel.
NB The IP address of the WAP must be within the same range as the boxes, so if the boxes
are 192.168.1.1 and 192.168.1.2 respectively then the WAP must be 192.168.1.X
respectively. It is suggested that the numbers above 240 are used for WAP’s so for example
the typical WAP address range would be 192.168.1.240 through 192.168.1.249
Any time a change is made on the WAP configuration page, the change must be committed
or applied to the WAP. If changing the WAP’s IP address and viewing the WAP’s
configuration page through Internet Explorer then you will have to change the IP address in
the IE address bar accordingly to reflect the new IP address.
To apply a change to the WAP you must scroll down to the bottom of the configuration utility
and click on Apply.
