44  ZeroWire Reference Guide 
WiFi Password 
Password required to access the WiFi network. Ask the administrator if you are 
not sure. 
Ports 
Here are the ports that the computer needs to communicate with the ZeroWire 
system. 
Defaults: 
•  HTTP Port = 80 
•  HTTPS Port = 443 
•  Download Port = 41796 
Time Server 
Enter the URL or IP address of a time server to allow the ZeroWire to 
automatically update and synchronise its clock without user intervention. The 
default is pool.ntp.org 
IP Options 
•  Enable DHCP: Allow the ZeroWire panel to be automatically assigned an IP 
address by the network. 
•  Enable Ping: Allow the ZeroWire panel to respond to the PING command. 
•  Enable Clock Updates: Allow the ZeroWire internal clock to synchronise with 
the internet time server specified. 
•  Enable Web Program: Enabling this option will cause ZeroWire Web Server 
and UltraSync + app to always display the Advanced menus when an installer 
logs in. 
Disabling this option will hide the Settings and Advanced menu on ZeroWire 
Web Server and UltraSync + app regardless of the login. To reveal the 
Settings and Advance menus, have a Master User press Menu 8 and enter 
their PIN code on the ZeroWire keypad. This provides greater security by 
disabling web programming until a user with adequate permissions enters 
their PIN on the physical ZeroWire panel on-site. 
•  Always Allow DLX900: Enabling this option will allow DLX900 to connect at 
any time if the correct Download Access Code is provided. Disabling this 
option provides greater security by only allowing DLX900 to connect when 
program mode is active. This allows the system to have DL900 access 
disabled until a user on site with physical access to the keypad enters 
program mode with a valid PIN code.  
ZeroWire will be in program mode if a user gains authorized access to menu 
5, 8, or 9. 
•  Monitor LAN: When the Monitor LAN option is enabled the panel will monitor 
the Ethernet port for a valid Ethernet cable. If the Ethernet cable is 
disconnected while this option is enabled, and the panel is unable to 
communicate, it will log a Fail To Communicate event.
