5.6. Base station firmware update
The latest firmware is always included in the latest ESL server application, which can be
downloaded from our FTP:
ftp://ftp.opticon.com/pub/ESL/
You can upgrade the firmware by selecting the base station in the base station-tab of the ESL
server application and pressing the firmware update button on the bottom right.
The firmware file for the base station can be found in the 'firmware' folder of the installation
directory of the ESL server.

5.6.1. Trouble shooting
If a firmware update fails, this can have a number of causes:
Older firmware versions require the EBSxx and ESL server to be on the same subnet
(connect the EBSxx on the same subnet)
One of the following ports is use: 67, 68, 69, 1002 or 13633 by another process (use netstat
to find out which process uses one of these ports.
Your firewall of router is blocking on of the above ports.
Your router/switch has its own bootstrap server (BOOTP) enabled. Check your manual of
your router on how to disable BOOTP (i.e. using ‘ip dhcp bootp ignore’ on Cisco systems) or
connect the EBSxx directly to your ESL server,
