Introduction

When Digi began serving

the utility industry, Dire Straits

Money for Nothing” topped

the Billboard charts, the first

cell phone was hitting the market

(weight: 1.3lbs, talk time: 1hr)

and Ronald Reagan was president.

We’ve come a long way since 1985, but the qualities that we started with—dedicated engineering, responsive tech

support and an industry-leading warranty—are the same qualities that allow us to continue serving the largest

investor owned utilities as well as the smallest rural electric cooperatives.

On the following pages we provide information on connecting common C&I meters with Digi TransPort® 3G and 4G

LTE cellular routers, as well as information on installation, cabling and antennas.

Special thanks are due to Digi customers in meter shops across the world. Thank you for sharing what you’ve

learned as you have used Digi product in the field.

Cellular Communications for Commercial and

Industrial Metering

Flexible and secure cellular routers connect remote

C&I meters with a utility’s meter data management system

for accurate billing and planning.

The utilities business is challenged from every angle to be increasingly productive and profitable. The very nature

of managing remote equipment in many locations can be difficult and expensive, and maximizing uptime while

reducing costs is often a requirement. Meter shops face a growing set of demands: more accurate and timely

billing, increased support for dispute resolution, measurement of power quality and reactive power, and support

for measuring the cost of power delivery. To meet these demands, metering professionals need a cellular router

that:

• Supports multiple Ethernet and serial devices

• Can be preconfigured for easy installation by field technicians

• Is certified on Sprint, Verizon, AT&T, Rogers and Telus

• Offers the high security features required by NERC/CIP

Digi TransPort® routers fit the bill. They are secure (dynamic routing, VPN and firewall support), carrier-agile

(supporting Sprint, Verizon and AT&T on one platform) and flexible (with Ethernet, RS232/485, GPS, USB and

analog/digital IO). Learn more at www.digi.com/transport.

Digi’s Solutions for the Utility Industry

Problem Solution

“Under the glass” cellular-enabled meters

can’t be moved to improve reception.

Digi TransPort routers oer several mounting

and antenna options.

Meter shops must support a mix of new and legacy

equipment with diverse protocols and physical interfaces.

Digi TransPort cellular routers have Ethernet and serial

ports, proven compatibility with common MDM systems and

support for DNP and Modbus.

No way to confirm proper communication between a

meter and router.

Digi TransPort routers can be pre-configured to double

check communication and green light

the installation.

Complicated installations require training and

documentation.

Pre-assembled, weatherproof Utility Communication Hub

simplifies installation.

Expensive and complicated to support a piecemeal

solution with products from

many vendors.

Digi oers a single source for all warranty

and support concerning the Utility

Communication Hub.

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

• 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.

Connecting the Digi Transport to Common

Electric Meters

3.1 Common Problems when Connecting to a Digi TransPort via

the Ethernet Cable

– Turn off the Wi-Fi on the laptop before connecting the Ethernet cable to the Digi TransPort. The Wi-Fi DHCP could

also be using the 192.168.1.X network.

– You may need to release your old IP address in order to acquire a new one from the Digi TransPort. On a Microsoft

Windows system you can do this by going to the command line (Start->Run->cmd) and entering ipconfig /release

followed by ipconfig /renew.

3.2 Connecting the Digi TransPort to Ethernet Capable Meters

(All Meter Types)

– In the Digi TransPort WebUI go to Configuration-Network > IP Routing/Forwarding > IP Port

Forwarding/Static NAT Mappings. This is where you will define where to redirect the communications from the

head-end server. Note that each meter IP and Port must be known. A typical configuration is below (IP addresses

and Ports may differ depending on how the meter is set up):

– After entering each rule hit the Add button. When finished hit the Apply button and then click on the Save here

button when it pops up. Hit the Save All button when the new window pops up.

Meter Engineers Handbook for Cellular Communication 6

– When using Static NAT Mappings the IP and Port on the cellular interface must be enabled. By default only the IP

port is NAT’d. Go here in the WebUI of the Digi TransPort: Configuration-Network>Interfaces>Advanced>PPP 1.

Scroll down to the checked box Enable NAT on this interface and check the circle for IP address and Port. Click on

the Apply button and Save All.

3.3 Connecting the Digi TransPort (WR21 Model Only) to Serial Meters

– Most meters come equipped with RS-232/485 ports to enable communications. The Digi TransPort WR21 serial port

can be configured for either RS-232 or RS-485.

– The Digi TransPort WR21 comes defaulted for RS-232 communication (115200 baud, Hardware flow

control, 8,n,1). To change these parameters go here in the Digi TransPort WR21 WebUI: Configuration-

Network>Interfaces>Serial>Serial Port 0. Check the user manual for the particular meter you’re connecting too

to see what these settings should be. Here is the pinout of the RS-232 port:

– The serial port needs to be set up as a ‘Port’ the Digi TransPort WR21 can forward too. To do this go here in the Digi

TransPort WR21 WebUI: Configuration-Network>Network Services. In the ASY 0 Listening Port: window type in

the port you want to use. By default this is port 4000 and it can be left as port 4000. In the following example it’s

been changed to port 2000:

RS-232 Port Pinout

Pin # Direction RS-232 DCE Description

1 Out DCD Data Carrier Detect

2 Out RXD Receive Data

3 In TXD Transmit Data

4 In DTR Data Terminal Ready

5N/A GND Ground

6 Out DSR Data Set Ready

7 In RTS Ready To Send

8 Out CTS Clear To Send

9 Out RI Ring Indicate

Meter Engineers Handbook for Cellular Communication 7

– Now redirect incoming communications to this port by using the port forwarding rules. Go here in the WebUI:

Configuration-Network>IP Routing/Forwarding>IP Port Forwarding/Static NAT Mappings. Add the rule to

forward to the serial port as below.

– Ensure that NAT’ing is applied on both IP address and Port by going here: Configuration-

Network>Interfaces>Advanced>PPP 0. Make sure the IP Address and Port circle is checked under the Enable NAT

on this interface check box.

Meter Engineers Handbook for Cellular Communication 8

3.4 Connecting the Digi TransPort WR21 to RS-485 Meters

– Similar to the RS-232 instructions, set up the Listening Port and the Port Forwarding rules and ensure the IP

Address and Port are enabled for PPP 1 interface. For pinouts from the various types of meters to the DB9 of the

Digi TransPort WR21 see below in section 4.

– The DB9 of the Digi TransPort WR21 is software selectable for either RS-232 or RS-485. To configure it for RS-

485 communication, go here in the WebUI: Configuration-Network>Interfaces>Serial>Serial Port 0. Drop the

Advanced tab down and in the Async Mode: box select RS-485. Terminating resistors are software selectable if

needed, there is no need to put external terminating resistors in place.
