GridRouter™ User Guide
2 Getting Started
Please review the reference documentation before you begin the installation and use of the supporting
software.
2.1 Operations
The GridRouter is a system that provides flexibility by implementing a card system that uses Field
Replaceable Units (FRUs) to implement a variety of network solutions that can be replaced as technology
changes. Wide Area Network (WAN) cards allow for a link to the Internet and ultimately to the back office.
Local Area Network (LAN) cards allow for aggregating or meshing of multiple meters on a WAN
connection. One of the popular use-cases establishes a connection between a conventional RS232 serial
interface and a TCP socket over a wireless protocol – CDMA or GPRS. It is intended for use by
commercial and industrial utility customers.
The GridRouter offers secure over-the-air transfer of data between the RS232/RS485 interfaces on the
GridRouter and any front-end system capable of TCP/IP communication.
2.2 Precaution
WARNING!
Use authorized utility procedures for installing, maintaining, and removing a GridRouter.
Equipment damage, personal injury, or death can result if devices are not used properly.
2.3 Prerequisites
To perform the installation of your GridRouter, you must have access to the following supporting software
and should have reviewed relevant documentation.
2.3.1 DNS Server Setup
The GridRouter supports dynamic DNS updates for modems that have dynamic IP addresses. A DNS
server must be set up and installed to use this feature. The GridRouter also supports and encourages the
use of transaction signatures (TSIG) as a mechanism to secure DNS messages to provide protected
server-to-server communication. TSIG uses shared secrets and one-way hash functions to authenticate
DNS messages and provide data integrity.
Berkeley Internet Name Domain (BIND) is the most commonly used DNS server on the Internet. The
newest version of BIND (BIND 9) supports the TSIG protocol. Microsoft DNS is the DNS server provided
with Windows Server and it, too, supports the TSIG protocol.
2.3.2 SNMP Server Setup
The GridRouter is a Simple Network Management Protocol (SNMP) agent capable of responding to
requests from SNMP management software. The GridRouter uses the SNMP TRAP operation to send
information to the network manager regarding events such as power outage and overheating alarms. To
make use of the SNMP functionality on the GridRouter, an SNMP management application must be
installed on a server and accessible from the GridRouter.

NOTE: Actual Configuration may vary
3.3.1 Power
The GridRouter power board is available in either an AC or DC configuration. For the AC configuration
the power plug should be connected to a 120VAC supply. The DC configuration should be connected to a
9-30VDC supply capable of at least 20 watts. The power switch is ON when pushed to the left, OFF when
pushed to the right. When first powered up the status LED will be solid orange for roughly 60 seconds
before it starts to blink. While the status LED is blinking orange during low-level boot up, holding down the
reset button for 6 seconds will result in a factory reset. The status LED will alternate between green and
red to designate this event. While the status LED is blinking green during normal operation, holding down
the reset button will turn the status LED red and result in a clean reboot of the GridRouter if held for more
than 6 seconds.
To cleanly power off the GridRouter, the reset button should be held until the status LED stops blinking.
Directly after the status LED turns solid orange again, the device should be powered off.
Failure to cleanly power off the GridRouter can result in data loss and possible corruption on the
system.

GridRouter™ User Guide
3.3.2 Ethernet
This Ethernet port connects the GridRouter to another Ethernet network device on a wired network. The
Eth1 and Eth2 LEDs represent Ethernet Link and Activity respectively.
3.3.3 Serial
There are two serial interfaces on the GridRouter and they have RJ45 connectors referred to as Port 0
and Port 1. A mezzanine board attached to the power supply board defines whether the ports are RS232
or RS485. The RS232 board makes both Port 0 and Port 1 communicate via RS232. The RS485 board
turns Port 0 into an RS485 port and Port 1 into an RS232 port. The RS485 board has 3 jumpers which
control whether the card is half-duplex or full-duplex. If all of the jumpers are installed then the board is in
half-duplex mode. If none of the jumpers are installed then the board is in full-duplex mode. The pin
definitions for both RS232 and RS485 ports are shown below.

3.4 Mounting Options
The GridRouter has several different mounting options for a variety of environments. Contact your
SmartSynch sales representative for information on available mounting hardware.
Note: SmartSynch is not responsible for damages incurred by unsecured mounting hardware.
13
GridRouter™ User Guide
4 Installing
4.1 Preliminary Inspections
The GridRouter is calibrated and tested at the factory and is ready for installation. Before installing and
applying power to the product, a quick inspection of the GridRouter is recommended to ensure there is no
damage to the GridRouter, which could possibly occur during shipping. Physical damage to the
GridRouter indicates potential damage to the inside of the GridRouter. Do not connect power to a
GridRouter that is suspected of having internal damage. Contact your SmartSynch technical support
representative if you suspect your GridRouter is damaged.
4.2 Installation Process
The SmartSynch GridRouter contains a cellular communications device. When the device is powered up
for the first time it will try to configure itself. The configuration process includes provisioning the modem
on the network, updating its hostname on the DNS server, and sending traps to an SNMP server.
4.2.1 Typical Installation Scenarios
On average, a technician will need 10 minutes to verify if a device has coverage. The GridRouter first
needs to be mounted correctly. Next, make sure that the power switch is in the OFF position (right) and
then attach the power connector. Wait until the battery LED illuminates before flipping the power switch to
the ON position (left). This could take up to 5 minutes.
The status LED will turn solid orange for approximately 120 seconds while the system is performing lowlevel setup for the first time. Once the high-level setup begins, the status LED will begin blinking orange
for approximately 60 seconds until the system is done with setup at which time the status LED will begin
blinking green.
The WAN LED for the modem will turn solid green when power is applied to the modem and it will begin
blinking green once the modem begins dialing out. If the modem is not provisioned, it will first try and
download the preferred roaming list (PRL) from the carrier before connecting to the internet. Once the
PRL successfully updates, the SGR will try and connect the modem to the internet and then try and
update its DNS entry in the specified DNS server. The DDNS LED will turn solid green once the DDNS
successfully completes. At this point, the GridRouter is fully operational.
4.2.1.1 Serial Device
Connect the serial cable between the end device and one of the serial ports on the GridRouter.
4.2.1.2 Ethernet Device
Connect an Ethernet cable between the end device and the GridRouter.
14
GridRouter™ User Guide
5 Provisioning the GridRouter
The provisioning processes must complete to ensure that the GridRouter can receive remote
communication.
5.1 Cellular Modem
GSM modems have SIM cards and can be activated and provisioned through the cellular carrier without
any interaction from the GridRouter. CDMA modems must be activated by the carrier and then
provisioned by the GridRouter, done by dialing a phone number. This provisioning process for CDMA
modems is necessary for downloading and updating the Preferred Roaming List (PRL). The GridRouter
queries the modem routinely and updates the PRL when necessary.
5.2 Dynamic DNS (optional)
If the GridRouter modem has a dynamic IP address, it is recommended to setup dynamic DNS so that
communication can be initiated remotely. The default hostname for the GridRouter is based upon its 10digit serial number: sgr{serial#}. An example hostname is sgr3509f00001. The default DNS server
hostname is dyndns.org.
An example DNS setup with www.dyndns.com uses a hostname of “sgr3509f00001.dyndns.org” and a
DNS server address of “update.dyndns.org”.

GridRouter™ User Guide
6 Configuration
6.1 Explanation of the UCI
The UCI (Universal Configuration Interface) is a collection of text files that contains the configuration for
the processes on the GridRouter. These settings can be altered through the web-based utility (HTTPS),
SSH, and the serial console.
16
GridRouter™ User Guide
6.2 Web Interface
ATTENTION – Windows XP and Internet Explorer users
The default GridRouter SSL cipher is set to AES with 128-bit encryption. This level of security is not
supported by Internet Explorer (IE) when used on Windows XP. It is recommended to use Firefox or
Opera when using Windows XP or to use Windows Vista/7. The GridRouter is capable of being
configured (pre-deployment or over SSH) to use a lesser form of encryption so that IE can be used on
Windows XP.
The web-based utility provides the ability to change the configuration settings on the GridRouter. You can
access the utility via a web browser on a computer connected to the GridRouter’s Ethernet port with the
default IP address, “https://192.168.0.254”, or over-the-air using the hostname or modem IP address.
The first time you open the web-based utility use the default user name “SGR_admin” and the default
password “admin_SGR“. (You can set a new password on the System > Password screen.) Click “OK“ to
continue.
Figure 6-1: Password Screen
The first time that you open the web-based utility on a given browser you will be forced to accept the
security banner by clicking “Enter”.
Figure 6-2: Security Banner
It is also worth noting that every screen in the web-based utility contains a common header and footer.
The header contains the firmware version, host name, uptime, date, time, and load. The footer contains
three links: “Apply Changes & Reboot”, “Clear Changes”, and “Review Changes”.
Pages that alter the GridRouter’s configuration all have a ”Save” button. The save button must be clicked
to temporarily write the files into RAM. The changes to the configuration can be reviewed by clicking the
”Review Changes” button and they can be committed to flash by pressing the ”Apply Changes &
Reboot” button.

“9000-9009,9011,9014-9016”.
Port Forwarding
Port forwarding is used to allow access to devices connected to the GridRouter. An example would be
accessing a device connected to the Ethernet of the GridRouter. To forward a single port, enter the
information on each line for the criteria required. The IP address “0.0.0.0” can be used to denote any
address.
Name: Specifies the name to give the rule. The name should not have any spaces.
Protocol: Select the protocol used for this rule, either “TCP“ or “UDP“, or “Both“.
Source IP: Specifies the IP address the request is coming from.
Destination Port: Specifies the external port number. Multiple ports can be specified using a hyphen and
commas: ” 9000-9009,9011,9014-9016”.
To IP Address: Specifies the local IP address that should receive the requests.
44
GridRouter™ User Guide
To Port: Specifies the internal port number. This value should normally be blank so that a 1 to 1 port
forward can occur. If, however, a value is specified here then any port(s) listed under “Destination Port”
will be redirected to this single port. There is currently not a way to forward ports 1-9 to 21-29 in a single

Figure 6-174: Network > DHCP
LAN DHCP
The DHCP settings for devices connected to the GridRouter through the Ethernet connector.
DHCP: DHCP is enabled by factory default. If a DHCP server is not desired, then select “Off“.
th
Start: Specifies the 4 octet of the IP address to start issuing IP addresses. For example, the default IP
address is “192.168.0.254“, so this start value must be less than 253 (192.168.0.253). The default Start
value is “1“ (192.168.0.1).
Limit: Specifies the maximum number of devices that the DHCP server will assign IP addresses to.
Lease Time: Specifies the number minutes a network user will be allowed connection to the GridRouter
with their current dynamic IP address.
Static IP Addresses
The DHCP server uses the matching IP address instead of allocating a new one from the pool for any
MAC address listed in this file.
Name: Specifies the name of the rule or end device.
MAC Address: Specifies the MAC address of the device that will be receiving the static IP address.
IP Address: Specifies the IP Address to assign to device with the specified MAC Address.
Device Type: Specifies the type of device receiving an IP address. This value should be “Generic“
unless connected to an Echelon Ethernet Data Concentrator (DC).
The Echelon DC requires that its local IP address changes when the GridRouter’s WAN address changes
to ensure that the DC will call back into the NES server. The least time should be around 5 minutes to
ensure that the DC will call back within 5 minutes of the WAN address changing. The local IP address
assigned to the DC will cycle through the range of address specified by the Start and End IP Addresses
each time that the WAN address changes. The suggested range is 10 addresses and 2 is the minimum.
Port forwarding firewall rules that have a “Static IP Rule” set to something other than “None” will
automatically be adjusted to match the DC’s address.

6.3.1.9 Serial PPP
Serial PPP is an application that acts as a modem emulator and provides a PPP connection to a device
connected serially to the GridRouter. Any device that would connect directly to a modem and issue AT
commands should be able to connect to the GridRouter and access the same network as the GridRouter
(whether public to the Internet or a private network). Some serial devices alert a head-end server
whenever their IP address changes, so the GridRouter has the capability to reset the serial PPP
connection whenever its WAN IP address changes. The GridRouter toggles between a primary and a
secondary local IP address when assigning one to the serial PPP device.
Figure 6-220: Network > Serial PPP
Configuration
Enabled: Default value is “Disable“.
Baudrate: Specifies the number of symbols per second transferred.

The GridRouter can provide network connectivity to a device that only talks over serial (RS232/RS485).
A single TCP port can be mapped to a serial port such that all traffic sent or received from either one is
passed through to the other. For instance, a software application that traditionally connects to a serial
port (i.e. COM5), could connect to an IP address and a TCP port and communicate to the end device.
The steps required to enable serial passthrough on the GridRouter are as follows:
1. Attach a serial cable (generally null modem) between one of the GridRouter’s serial ports and the
device’s serial port.
2. Visit the web-based utility’s Network > Serial Passthrough screen.
3. Click the “Enable“ button on an instance of the serpass process (i.e. serpassA).
4. Enter the correct serial port settings (baudrate, data bits, parity, stop bits).
5. Enter the correct TCP settings (port and timeouts).
6. Click Save Changes and wait for the page to refresh.
7. Verify configuration values.
8. Click Apply Changes & Reboot.
Once the GridRouter reboots, the serpass process will be running and passing data between the
specified TCP port and the specified serial port.
Note: The GridRouter’s firewall will automatically allow incoming traffic on the specified TCP port for
serpass.

7.2 Serial Data Concentrator to NES
When a serial Echelon Data Concentrator (DC) is connected directly to a modem it dials a number with an
AT command (i.e. “ATDT10001”). The modem will respond with “CONNECT” and then the Point-to-Point
Protocol (PPP) will be used to establish a direct connection between the DC and the Internet service
provider (ISP). The GridRouter acts as a modem emulator and will listen for the “ATDT” command before
responding with “CONNECT” and then initiating the PPP connection.
The DC will natively try and alert the head-end server (NES) whenever its IP address changes. Since the
DC is on the GridRouter’s local network (192.168.*.*), the DC’s IP address will normally stay the same, so
that the firewall rules can be the same. Therefore, the DC will never alert the NES server when the WAN
address of the GridRouter changes, leaving the DC without communication.
The GridRouter has the ability to change the local IP address of the DC when the WAN address changes
to force the DC to alert NES. A primary and a secondary IP address are toggled and assigned to the DC
and the firewall rules are automatically altered to match the DC’s address. To ensure that this toggling of
addresses is used on the DC, make sure to enable the ‘Update Local IP’ rule on the web interface.
The steps required to set up the GridRouter to connect to a Data Concentrator are as follows:
1. Attach a null modem serial cable between the Data Concentrator and a GridRouter serial port.
2. Visit the web-based utility’s Network > Serial PPP screen.
3. Click the Enable button on an instance of the serppp process.
4. Enter the correct serial port settings.
5. Enter both a primary and secondary local IP address to assign to the Data Concentrator.
6. Disable ‘Update Local IP’ if your GridRouter has a static IP address.
7. Add port forwarding rules so that the NES software can reach the Data Concentrator through the
GridRouter’s firewall.

8. Click Save Changes. Wait for page refresh.
9. Verify configuration values.
10. Click Apply Changes & Reboot.
Once the GridRouter reboots, the serppp process will be running and the Data Concentrator will be ready
to go.
Note: Common communication ports for the Echelon Data Concentrator are 65432, 65400, and 22 (SSH).

7.3 Ethernet Data Concentrator to NES
The Ethernet Data Concentrator (EDC) is slightly different than a “normal” Ethernet device. As with the
serial Data Concentrator, the EDC alerts the head-end server when its IP address changes. If the
GridRouter has a static WAN address then a static local address can be assigned to the EDC and
everything will work like a “normal” Ethernet device. If the GridRouter has a dynamic IP WAN IP address
then the GridRouter has to routinely alter the local IP address assigned to the EDC so that it will call into
the head-end server. The EDC must be set up for DHCP, else this will not work.
The GridRouter will statically assign an IP address to the EDC based upon its MAC address. The
leasetime is set to 5m so the EDC will request an IP frequently. If the GridRouter WAN address changes,
it will change the IP address assigned to the EDC.
The steps required to set up the GridRouter to connect to an EDC are as follows:
1. Attach an Ethernet cable (straight or crossover) between the EDC and the GridRouter’s Ethernet
port.
2. Visit the web-based utility’s Network > DHCP screen.
3. Create a Static IP address rule
a. Set the name (no spaces)
b. Enter the MAC address in the form aa:bb:cc:dd:ee:ff
c. Select a local IP address to assign to the EDC. Make sure it is on the same subnet as
the GridRouter.
d. Select “Echelon DC” as the Device Type.
e. Provide a Start IP Address. This should be the same as the IP address from above.
f. Provide an End IP Address that is roughly 10 addresses larger than the start. The range
can be as small as 2 but is recommended at 10.
g. Set the leasetime to something around 5 minutes. This is essentially the maximum
amount of time that the EDC will be waiting before it contacts the head-end server after a
WAN IP change.
4. Click Save Changes. Wait for page refresh.
5. Visit the web-based utility’s Network > Firewall screen.
6. Add Port Forwarding rules so that the NES software can reach the EDC through the GridRouter’s
firewall. Be sure to set the “Static IP Rule” equal to the name of the DHCP name provided earlier.
This value is in a drop down.
7. Click Save Changes. Wait for page refresh.
8. Click Apply Changes & Reboot.
