ISSUE: Updating a WLN10/WLN10HS to Latest AP Firmware
A recent firmware update V4.00 now allows WLN10 products to work in Access Point mode rather than Ad-
Hoc Mode. This results in a more stable and reliable network connection and also allows Android devices
(which do not support Ad-Hoc networking) to connect to a WLN10.
This Tech Note details a procedure that will allow you to update a WLN10 using a home/office wireless
network, assuming that this network provides network settings automatically (using DHCP), that it has an
internet connection and you know the SSID and Password of the network.
Updating a WLN10/WLN10HS involves connecting the WLN10 to a PC via an NMEA to USB adaptor.
Sending it commands via Tera Term running on the PC and then instructing the WLN10 to connect to your
home/office wireless network and to go online via the internet to download the latest firmware from an
FTP site.
IMPORTANT - Prior to starting this process, please make a note of the four digits in the wireless network
name (SSID) of your WLN10 unit i.e. DY-WLN10-1234 you will need this number later after updating your
WLN10.

EQUIPMENT NEEDED:

1) PC with latest copy of Tera Term installed
2) Copy of "TTL Editor", part of the Tera Term installer for editing the Tera Term Macro Script
3) 12v Power Supply to provide power to WLN10
4) Wireless Network with connection to internet
5) Digital Yacht NMEA to USB Adaptor (or similar)
The procedure shows how to do this using one of our USB to NMEA adaptors
but you can use an old PC with a 9 pin serial port or another make of serial to
USB adaptor. If connecting to a 9 pin D-Type connector, you should connect the
WLN10 Yellow wire to the RS232 TD (pin 3), the Orange Wire to the RS232 RD
(pin 2) and the Green+Brown wires to RS232 Ground (pin 5) – see image.
