Enter a network address for an AMS Trex unit
You can specify how an AMS Trex unit connects to your network. Enter DHCP to allow a
network address to be assigned, or Static to specify an IP address and/or Subnet Mask.
Note
Contact your network administrator before changing settings. Ensure the port you are
sending to is configured to receive AMS Trex data.
Procedure
1. Tap Settings.
2. Tap Wi-Fi, and turn on Wireless Networks.
3. Tap IP Address, and tap the IP Address Assignment line to change from DHCP to
Static.
4. Enter an IP Address, and/or Subnet Mask.
5. Tap OK.
Forget a wireless network
Forgetting a wireless network prevents the Trex unit from automatically reconnecting to
it. You can forget a network to which you are currently connected, or one where you have
entered credentials.
Procedure
1. Tap Settings or the status bar at the top of the screen.
2. Tap Wi-Fi, then tap the network.
3. Tap Forget.
The network disconnects. If there is data that has not been synchronized with AMS
Device Manager, you are prompted to confirm before disconnecting.
Change the default connection port
AMS Trex communicates with wireless networks at port 8009. If your network uses this
port or restricts access to it, AMS Trex may not be able to communicate with the network.
Contact your network administrator for details.
Procedure
1. Tap Settings → Platform Communications.
2. Tap to change the default, and enter a port number.
Postrequisites
If you change the default port for one AMS Trex unit, Emerson recommends setting all
AMS Trex units to exchange data on that port. All AMS Device Manager stations that
synchronize with AMS Trex units must also have the same port number. See AMS Device
Manager Release Notes for details on changing port settings on the PC.
