Setting the Static IP Address
To enter a fixed IP address into your clock’s firmware, start a telnet session with the clock
and the use the following command option:
ipconfig -a xxx.xxx.xxx.xxx -m yyy.yyy.yyy.yyy -g
zzz.zzz.zzz.zzz
where
xxx.xxx.xxx.xxx is the IP address, yyy.yyy.yyy.yyy is the subnet mask,
and zzz.zzz.zzz.zzz is the gateway address. All fields must be provided.
Note: Your IT staff must authorize and provide a static IP address to prevent operational
problems which might occur if that address is applied to another device on the network.
Specifying a Time Server
The network time server on the LAN, WAN, or on the internet may be specified by IP Address
or by Host Name.
• Specifying by IP address is typically only safe if the address of the server is under your
IP Group’s control. When specifying time servers on the internet, use the Host Name.
• Specifying by Host Name requires that a DNS server is accessible to the clock:
• If IP addressing is static, the DNS servers must be identified and configured
as well.
• If IP addressing is via DHCP, the DNS servers are typically already
automatically configured (do not over configure!)
The process for specifying a time server is the same for both Host Name and IP Address.
1. Log into the OnTime Digital Clock.
2. At the prompt, type: sntp –h.
3. Press the spacebar.
4. Enter the Host Name of the time server – e.g.
5. Press the Enter key.
