  Initial Setup and Configuration for  
Digi Transport® WR21, WR41 and WR44
2.1  Common Digi TransPort Setup Procedures for all Meter Types
  PRE-CONFIGURATION OF DIGI TRANSPORT
Required equipment for this configuration:
• 
Digi TransPort WR21, WR41 or WR44
• 
Computer or laptop
• 
Ethernet cable
• 
SIM and data plan purchased from a carrier (Verizon, ATT, etc.)
  CONNECTING TO THE CARRIER
 –
Insert the SIM into SIM 1 slot on the front of the Digi TransPort and screw on both WWAN antennas.
 –
Connect the Ethernet cable to port 0 of the Digi TransPort (some models only have one Ethernet port).
 –
Connect the Ethernet cable to the laptop.
 –
Power on the Digi TransPort.
 –
Open a browser on the laptop; i.e., Internet Explorer, Firefox, Chrome, etc.
 –
In the URL window type 192.168.1.1. The default configuration of the Digi TransPort has the DHCP turned on so 
the laptop will be given an IP address automatically. The built in WebUI of the router should now be displayed (see 
section 1.2 for common problems if you aren’t able to connect).
 –
When the login screen comes up, type in the username and password. The default username and password is 
username and password (all lower case). After login you will go immediately to the Home screen.
 –
On the menus to the left, just below the Home option, you will see the Wizards option. Click on Wizards and then 
choose the Carrier Switching Wizard. Follow the directions in the Wizard and pick whichever carrier you’ve chosen.
• 
If you are using Verizon there is nothing else to do. It might take 10-15 minutes but the Digi TransPort will self 
register and populate its APN.
• 
If you are using AT&T (and some others) then an APN must be manually entered here: Configuration-
Network>Interfaces>Mobile. Click on the button to Use custom APN instead of built-in APN and enter the 
APN (Check with your carrier as to what APN your particular SIM uses, some common ones for AT&T are 
broadband, INTERNET and i2gold). It may take 10-15 minutes for the Digi TransPort to register.
