Time Settings
The Gateway is the timekeeper for the WirelessHART network, so it is
imperative that the Gateway’s time is accurate for timestamp data to be
meaningful. Time settings can be found by navigating to Setup>Time.
There are three ways to set the Gateway time:
1. Network Time Protocol (recommended).
This option uses a Network Time Protocol (NTP) server to slowly
adjust the Gateway’s time in order to match the time of the control
network. Enter the IP address for the NTP server and select the
packet version (1, 2, 3, or 4).
2. Set with PC Time.
This option will match the Gateway’s time to that of the PC/Laptop.
3. Manual Entry.
This option allows the user to enter a specific date (MM:DD:YY) and
time (HH:MM:SS).
NOTE
Network Time Protocol (NTP) is recommended for the best network
performance because it always adjusts time to match the network time server.

TCP/IP Network Settings
Prior to the gateway being installed and connected to a live control network, it
should be configured with an IP address, as well as other TCP/IP network
settings.
Request the following configuration items from the network administrator:
• Specify an IP address, or use a DHCP server
• Hostname
• Domain Name
• IP address
•Netmask
• Gateway
Obtaining an IP address from a DHCP server is not recommended, since the
Gateway operation will be dependant on the availability of the DHCP server.
For maximum gateway availability it is best practice to specify an IP address.
Use caution when making changes to the TCP/IP network settings. If they are lost or
improperly configured, it may be impossible to log into the Gateway. Contact the network
