ISSUE:
Using our Wireless Products with an existing wireless network
All of Digital Yacht's wireless NMEA devices use the same Wi-Fi module that is pre-configured during
production with settings that will give good operation for the majority of customers. However, some
customers have requested the ability to change some of these settings i.e. the wireless SSID network
setting, or to make the product join an existing wireless network onboard the boat.
This Tech Note provides a command reference that explains how to check and change many of the settings.
This procedure is not recommended for all customers and assumes a certain level of experience and
expertise in wireless networking.
SOLUTION:
To configure our wireless NMEA products you need to use a free terminal program called Tera Term. To
carry out this configuration, it is necessary to have a Windows PC that has a wireless adaptor and a copy of
"Tera Term" installed. A copy of this program is included on the Digital Yacht "Software and Drivers" CD-
Rom (in the Utilities folder), or is available for download at the link below;

After installing Tera Term, it is necessary
to connect the PC to our wireless device
using the Windows Wireless Network
utility, scan for available networks and
connect to the device to be configured.
Once connected, run Tera Term and when the "New Connection" window is displayed, select the TelNet
service, enter the IP address and Port number of our wireless device – which is 169.254.1.1 Port 2000.

- Page 4 Digital Yacht wireless products can only create OPEN (unencrypted) networks which does mean that anyone can connect to them. At sea this is very unlikely to cause a problem, unless you don’t trust your crew (!), but it is possible to make all of our wireless products connect to an existing encrypted wireless network.

- Page 6 If your wireless device has UDP enabled (all units sold since April 2012) or you have enabled this yourself by following our Tech Note 00030-2012, then you do not need to find out what IP address your wireless product has been given, simply connect your iPhone/iPad/Laptop/etc. to your wireless network and then initiate a UDP connection on port 2000.
