Power Connector
The ZyWAN-G9 can be powered from 10 to 26 VDC. Power to the ZyWAN-G9 is supplied via the 4pin power socket (mating connector: Kycon KPPX-4P plug). The power plug must be inserted with the
flat part of the plug facing up (toward the top of the ZyWAN front panel). The pin configuration is as
follows:
The ignition sense input is intended for sensing the
on/off condition of a vehicle‟s ignition, but it is not yet
supported in the ZyWAN-G9 application software.
Ethernet
The pin assignments for the Ethernet LAN connection are shown in the following table. The yellow
LED is a Link/Activity light, which illuminates when a 10/100Base-T connection is made and flashes
when there is data activity. The green LED illuminates when a 100 MB/s connection is made.
USB
The external USB port is a standard USB 1.1 port available for general use.
Two other locking USB 1.1 ports are available under the ZyWAN-G9 in a covered bay, and are
intended to be used with peripheral devices, generally cellular modems. To release the locking USB
ports, press in the lever above the port while removing the USB peripheral device.
Antenna Connections
The Antenna A and Antenna B connectors on the front of the ZyWAN-G9 are SMA connectors, which if
fitted will come from devices mounted in the USB bay. The Antenna C connector is another optional
position for an SMA connector, which may come from a built-in modem mounted internally (not in the
USB bay).

RS-485 / RS-422 wiring diagrams
When connecting RS-485 or RS-422 devices in a multidrop configuration, there must usually be a
120 termination resistor at one or both end devices in the network but NOT on any devices in the
middle of the loop. The ZyWAN-G9 provides a 4-wire RS-485/422 interface.
In RS-485 or RS-422 systems, connect the ground terminal in common between all devices. It is
recommended to use shielded, twisted pair cable. Connect the cable shield to the RS-485/422 ground
AT ONLY ONE POINT in the network. In the ZyWAN-G9, the RS-485/422 ground is in common with
other electrical grounds in the system.
The following wiring diagrams show the correct device connection arrangements.

Tip:
If your network administrator can determine the DHCP assigned address after the ZyWANG9 starts up, the serial cable is not needed. Skip to 4. Browse ZyWAN Configuration Page
on page 35.
Note:
If the ifconfig command does not show an inet addr address, it may be that the
network does not have a DHCP server or that security policies prohibit the ZyWAN-G9 from
obtaining its address. A temporary address can be manually set if necessary by issuing the
following command:
ifconfig eth0 ip_address netmask subnet
where ip_address is the actual address on the network, and subnet is the subnet
mask in dotted notation (such as 255.255.0.0).
3. Determine ZyWAN Network Address (DHCP)
Port 0 on the ZyWAN-G9 is typically set to acquire its address automatically using DHCP. Since the
address is dynamically assigned, the ZyWAN-G9 address must be determined before it can be
configured.
One way to check the ZyWAN-G9 network address is to use a crossover (null modem) serial cable
between the PC and the ZyWAN-G9. The null modem cable can be purchased from Eurotech, or it
may be obtained from an electronics supply store.
To determine the ZyWAN network address (DHCP), complete the following steps:
1. Use PuTTY or HyperTerminal to establish communication to the ZyWAN-G9 on COM1 at 115,200
baud. See Setting Up Software on page 25, for help with this step.
2. If the ZyWAN-G9 is already started, press the Enter key to get a login prompt. The default login is
root and the default password is arcom (case-sensitive).
3. After logging into the ZyWAN-G9, type the command ifconfig eth0 at the command prompt.
The current network address which has been assigned to the ZyWAN-G9 by the network is
displayed.

Troubleshooting Connection Problems
If the Web configuration page does not come up with the instructions given in the last two sections,
there are several things which can be done to troubleshoot connection problems.
Unable to Load Web Page
If the Web configuration page fails to load, the following are common reasons why this might happen.
1. Due to network configuration, the computer making the connection may not be able to reach the
ZyWAN-G9. Check connection to the Web page by doing a ping command (see Ping the ZyWAN,
on page 37). However, if trying to connect over the Internet/cellular connection, a ping may fail
because it is blocked by the cellular network. In this case, try making an SSH connection with the
PuTTY application (see SSH Client, Terminal Program (PuTTY) on page 26 for help installing
PuTTY), because the SSH connection should work if a connection can be made to the ZyWAN-G9.
2. Over the Sprint network in the United States, it may be that port 80 is blocked. In the Web
browser, try entering the full HTTPS address of the ZyWAN-G9 (https://ip_address/cgi-
bin/php/main.php, where ip_address is the address of the ZyWAN-G9), which may work to load the
Web page.
Ping the ZyWAN
To ping the ZyWAN, complete the following steps:
1. In the Windows Start menu, select Accessories>Command Prompt. The Command Prompt
window is displayed.
2. Type the command:
ping address
where address is the numeric address of the ZyWAN-G9.
A diagnostic message is sent to the ZyWAN-G9 to check communication. If successful, the Ping
response receives the following reply.
Page 38
ZyWAN-G9 - User Manual

110150-4002A
Check the PC’s Network Configuration
To check the PC‟s network configuration, type the command ipconfig /all in the Command Prompt
window. The network interface of the PC is displayed.
If using the ZyWAN-G9 as a DHCP Server to the PC:
Make sure the PC Dhcp Enabled is set to Yes.
Make sure that the PC has been given a proper address from the ZyWAN-G9, according to how it‟s
configured.
If using the PC in a fixed address mode, check the address and make sure that it is compatible with
the address and subnet necessary to communicate on the network or direct to the ZyWAN-G9,
depending on the test being performed.
If the ZyWAN-G9 is acting as a DHCP Server to the PC and is configured to serve the DNS addresses,
these are displayed in the ipconfig settings.
Using ZyWAN COM1 for Diagnostics
When using a null modem serial cable connected to COM1, as described in Initial Connection Over a
Network on page 34, several commands can be issued to the ZyWAN-G9 to diagnose network
configuration or operation.
To check network configuration or availability, use the command
ifconfig
To set a temporary network address on an interface, use the command:
ifconfig interface ip_address netmask subnet
where interface is the network name (eth0, eth1, eth2), ip_address is the actual address on the
network, and subnet is the subnet mask in dotted notation (such as 255.255.0.0).
To send a diagnostic message to another device on a network, use the command:
ping address
where address is the numeric or named address of another device. Press Ctrl-C to stop the ping.
Page 39
PART 1: GETTING STARTED
39
110150-4002A
To check the route table of the ZyWAN-G9, use the command:
route –n
To make a TCP/IP connection to a port on a device, use the command
nc ip_address ip_port
where ip_address is the device address on the network or 127.0.0.1 for the ZyWAN-G9 itself, and
ip_port is the network port.
Check with Network Administrator
If you are still unable to get the ZyWAN-G9 to connect to an existing network, check with a network
administrator for additional support.

Using Default Gateway, DHCP, and DNS
The ZyWAN-G9 provides two Ethernet (eth0, eth1), WiFi (eth2), and cellular (ppp0, ppp1) interfaces.
Each of these interfaces can potentially have a Default Gateway address, DHCP, and DNS server
addresses. One of these interfaces will be made the default route to reach addresses that are not
otherwise available on its local networks.
Configuration Options
The Ethernet interfaces can be configured to be a DHCP client on an existing network (the Use Dhcp
Client? option set to Yes). The WiFi interface can be configured in similar manner (in “managed
mode”). In this case, it is likely that the ZyWAN-G9 will obtain a Default Gateway and DNS server from
the network to which it is attached.
Static IP addresses may also be configured. This allows the Ethernet or WiFi to be configured with a
Default Gateway and one or two DNS Server addresses for the interface. These items may be left
blank if there is no server available or if it does not make sense to include them in the configuration.
When configured with a static IP address, the Ethernet interface may be configured to Run DHCP
Server. This will allow the ZyWAN-G9 to assign an IP address to other devices on the network. The
WiFi interface in “master” mode defaults to static IP and also provides a DHCP server to wireless
clients.
Default Route
The ZyWAN-G9 will make one of its interfaces the default route based on the configuration and the
availability of each network. The order of preference for the default route is:
Ethernet 0 (eth0)
Ethernet 1 (eth1)
WiFi (eth2)
Cellular (ppp0, ppp1)
The first interface which has a Default Gateway (static configuration in Web page, or obtained
dynamically from a DHCP server) will be the one used for the ZyWAN-G9‟s default gateway. If the
Ethernet cable is unplugged or the WiFi is unavailable, the list of interfaces is checked again, and the
first available interface will be selected dynamically as the default route, in order of preference.
This means, for instance, that if an application requires the cellular network to be the default gateway
for network traffic, any Default Gateway (configured explicitly in the ZyWAN-G9 Web configuration or
obtained from a DHCP server) will interfere with the intended operation. Therefore, care needs to be
taken to avoid this situation. For instance, this may require disabling or setting the Ethernet and WiFi
to static IP addresses without the Default Gateway (leaving it blank), to allow the PPP interface to
become the default gateway.
DHCP Server and NAT
If either the Ethernet or WiFi (master mode) is running as a DHCP server, then the ZyWAN-G9 will
respond to any client device on the network that requests an IP address. The ZyWAN-G9 will assign
the device an address in accordance with the list of addresses specified in the ZyWAN-G9 Web
configuration. The client device will use the ZyWAN-G9‟s network address as its Default Gateway.
Thus, if the ZyWAN-G9 is used on a local network where another DHCP server is already running, the
Run DHCP Server option should generally be set to No.
The Open Ports section on the Networking page must include UDP port 67 to allow DHCP traffic to the
ZyWAN-G9.
Page 51
PART 2: SOFTWARE CONFIGURATION
51
110150-4002A
The ZyWAN-G9 is able to act as a gateway, but in order to route traffic from one interface to another,
there must also be a NAT entry configured on the Networking page to route from the source network to
the destination network.
DNS Server
As a DHCP Server, the ZyWAN-G9 also acts as a DNS server, responding to client devices‟ requests
to resolve named addresses (URL or FQDN) into numeric addresses. The ZyWAN-G9 acts as a DNS
proxy, so that any DNS requests from the client device are passed to one of the DNS servers known to
the ZyWAN-G9, and the resulting IP address is returned to the client device.
In order to resolve DNS addresses, the ZyWAN-G9 needs to know the location of one or more DNS
server(s). It obtains the list of these servers in the same way as it obtains its default route, either
statically configured or obtained dynamically. On whichever interface is currently the default route
(eth0, eth1, eth2, ppp0, ppp1, etc.), the DNS servers may be obtained from that network or statically
defined in the Web configuration. This list of address(es) is used by the DNS proxy.
The Open Ports section on the Networking page must include UDP port 53, to allow the ZyWAN-G9 to
receive DNS requests.

FIELD/OPTION
EXPLANATION
Server IP Address:
Enter the numeric IP address or fully qualified domain name (FQDN) to
which the UDP packets are sent containing GPS data. This is the address
of the host computer, which must be available on the network (such as the
Internet) to receive this data. Each of the four fields must be a number
between 1 and 255. If the ActSoft Format is used, this IP address should
generally be gps.comettracker.com.
Server Port Number:
Enter the destination port number on the host computer which receives the
GPS data over UDP. Port numbers must be a number between 1 and
65535. If the ActSoft Format is used, the port number should generally be
8502.
Request Interval:
Enter the interval (in seconds) for how often the GPS data is obtained from
the GPS receiver. Range is 1 to 65535 seconds for the Arcom mode, 30 to
65535 for ActSoft mode. Multiple GPS positions can be collected and
buffered, to be sent all together as determined by the Send Threshold, in
order to reduce the network traffic.
Send Threshold:
Enter the Send Threshold as a number between 1 and 19. The Send
Threshold is a numeric value which indicates how many GPS positions
should be sent in one position message. The position message will not be
sent until the specified number of GPS positions have been obtained from
the GPS receiver.
Unit ID:
Enter a unique 10-character unit ID which identifies the GPS data from this
ZyWAN-G9 when reported to a host computer. This allows the host
computer to have unique identifiers for data coming from multiple remote
units.
When using the Actsoft Format, this Unit ID must be a unique 10-character
serial number to identify this device in the Actsoft system.
For ZyWAN-G9-iDEN: The Unit ID reported to ActSoft must be the 10character modem serial number.
For all other models: The Unit ID is a unique 10-character serial number,
with format to be specified by ActSoft.
Warning:
It is essential to observe that this Unit ID field is entered
correctly. If not and if duplicate ID‟s are reporting from
any other device, both remote devices may suffer loss
of data and an interruption of GPS reporting service.
Enable Cache?
Select Yes to enable caching of GPS data. When caching is enabled, the
ZyWAN-G9 stores 100 positions in non-volatile memory. After this cache is
filled, the oldest positions are discarded. Once the network connection is reestablished, positions in the cache will transmitt in a first-in, first-out order.
This is the only option for ActSoft mode, and the option is not available to
set to No.
When Enable Cache? is set to Yes, a UDP acknowledgement is required
from the host computer, which allows the ZyWAN-G9 to verify the data has
been received. If the UDP acknowledgement is not received, the data
points begin to be cached.
The Enable Cache? option requires that the ZyWAN-G9 network
address must be accessible to the host computer, since the host
must initiate a one-way UDP acknowledgement message to the
ZyWAN-G9. If the acknowledgement is not received (due to
network problems, etc.), the ZyWAN-G9 caches the GPS points
based on the Request Interval and Send Threshold parameters
(above) and continues trying to send the next point every 10
seconds.
The following table lists the fields and options offered.
PART 2: SOFTWARE CONFIGURATION
Page 86
ZyWAN-G9 - User Manual
86
110150-4002A
When Enable Cache? is set to No (Arcom format only), a UDP
acknowledgement is not required. The ZyWAN-G9 simply sends out the
GPS points when it can and does not store them locally. If the host
computer does not receive the position message, those positions are lost.

Arcom Format for GPS Messages (UDP)
When using the Arcom Format for GPS data, the position message is transmitted using the User
Datagram Protocol (UDP). If caching is enabled, the ZyWAN-G9 waits a minimum of 10 seconds to
receive an acknowledgement message after transmission of a position message. If a response
message is received that does not contain the characters ACK or no message is received within the
timeout period, the position message is retransmitted. This process continues indefinitely. The ACK
must be 3 ASCII characters (0x41 0x43 0x4B).
The position message is defined next. The first 12 bytes are a header, followed by 19-byte portions
containing the timestamp and position information. The number of these 19-byte portions is
determined by the Send Threshold parameter. All data is in binary big-endian format, unless otherwise
specified.

entered at the Terminal Client serial port. The OK response is similar to the
way in which a modem responds to a computer over its serial port.
DTR Indicates Connect
State
Specify whether DTR indicates the IP connection state. If set to Yes, the
serial port‟s DTR output is asserted to a positive voltage when the IP
connection is established, and is de-asserted when the IP connection is lost.
This is meant to operate similar to a Carrier Detect (CD) output from a dial
modem, which is asserted after a data connection is established.

Client waits before attempting to re-establish a lost connection with the
server, if the connection has been dropped for any reason. This option only
applies when the Connect Mode is set to Continuously.
Connect Mode
Choose the connection mode. The options available are:
Continuously: Connect automatically upon system restart or upon either
device dropping the IP connection. There must be only one Host
Connection row, and its Matching Dial String field must be left empty.
Any Data: Connect only when data is received from a serial device
connected to the COM Port. There must be only one Host Connection row,
and its Matching Dial String field must be left empty.
ATDT String: Connect only if an ATDT### message is received on the serial
port, where ### is some alphanumeric string. There may be many Host
Connection rows configured under this Terminal Client, with their Dial String
set to unique ATDT### values. The ATDT mode acts as a modem emulator,
whereby each ATDT dial sequence initiates a connection to an IP address.
Until a matching dial string is received, the ZyWAN-G9 does not make an
outbound Terminal Client connection. See Matching Dial String for more
details.
Use DCD Pin: Connect if the Data Carrier Detect (DCD) input signal on the
serial port is raised to a positive RS-232 voltage. This must be used with an
RS-232 port and does not apply when COM3 uses the RS-485 hardware
option. There must be only one Host Connection row, and its Matching Dial
String field must be left empty.
ATDT or DCD: Connect if either ATDT### message is received or if the
Data Carrier Detect (DCD) signal on the serial port is asserted. If the ATDT
message is received, it is compared against the Matching Dial String in the
Host Connection rows to find which IP address to use for connection. If the
DCD is received, the ZyWAN-G9 is connected to the IP address of the first
Host Connection row with an empty field for the Matching Dial String.
Serial Driver
Select whether to use the Native Linux (ttyS) serial driver or the ACSCOMM
Eurotech driver. The ACSCOMM option allows for half-duplex RS-485
communication, and it can provide better handling of hardware flow control if
needed.

Remote IP Port
Enter the port number (between 1 and 65535) to which the Terminal Client
connects. The same port number is used to attempt connections to each of
the three IP Addresses, if configured. There is no option to connect to
different port numbers for each address in the Host Connection row.
Disconnect Mode
Select when to disconnect from the remote address. In any case of a
session disconnect, the Connect Mode (above) determines how a
reconnection occurs.
Options available are:
On +++: Disconnect if three characters +++ (and no more than three) are
received on the serial port within the Demark Time. This emulates the
modem attention string often used prior to hanging up a dial connection.
On Dropped DCD: Disconnect when the Data Carrier Detect (DCD) input on
the serial port goes to a low (inactive) state.
Either: Disconnect either on receiving +++ at the serial port or on an inactive
serial DCD line.
Neither: Never disconnect from the remote server. Connections may still be
lost due to the remote side dropping its connection or due to network
interruptions.
Echo Connect Strings?
Choose whether to echo all commands.
The options are:
To Async: Echo the Connect Message and Failure Message to the serial
port after a connection attempt or after the Terminal Client disconnects.
To Async and Socket: Echo the Connect Message and Failure Message to
the serial port and to the remote server after a connection attempt or after
the Terminal Client disconnects.
Neither: Do not echo the strings to the serial or TCP port.
Matching Dial String
Enter the ATDT string that is used to make a connection if the Connect
Mode option is set to ATDT or ATDT or DCD. Otherwise, this field must be
left empty.
If used, the string must always start with the letters ATDT and be followed
by some unique text (uppercase/lowercase text is treated identically, and
spaces are ignored).
For instance, the Host Connection rows may contain Matching Dial Strings
of ATDT1, ATDT555-1212, ATDTDIAL. When any of these strings is
received on the serial port, the ZyWAN-G9 attempts to connect to the first
configured IP address of its Host Connection row.
Connect Message
Enter a text message (such as “CONNECT”) sent to the network and/or
serial port when a network connection is established to the remote address.
This text is only sent when the Echo Connect Strings? is set to something
other than Neither. This option emulates a modem‟s option to echo a
connect message to a dialing computer. This field may be left blank if no
message is desired.
Failure Message
Enter a text message (such as “NO CARRIER”) sent to the network and/or
serial port when the Terminal Client disconnects from a network connection
and to the serial port when a connection attempt fails. This text is only sent
when the Echo Connect Strings? is set to something other than Neither.
This option emulates a modem‟s option to echo a fail message to a dialing
computer. This field may be left blank if no message is desired.

Time to Live
Enter the Time To Live for the connection (in seconds). This is the
maximum time of no activity from the network-connected client, before the
ZyWAN-G9 closes the Terminal Server connection. The range for Time To
Live is 1 to 65535 seconds. (Setting the value to zero (0) will cause the
Terminal Server to never shut down upon no activity, which is not
recommended.)
Duplex
Select the duplex mode for the Terminal Server. This selects a mode of
operation for handling bi-directional communication with a serial device.
Full Duplex: This mode is designed for unsolicited data from serial devices,
full bi-directional communication, or any serial protocol which may send
large or multiple responses to a request. In this mode, the Terminal Server
is always able to receive data on both the serial and network ports, as long
as a client is connected to the IP Port.
Half Duplex: This mode is designed for simple request-response networks,
especially where serial port sharing with another Terminal Server may be
required. After a request is received from the network and sent to the serial
port, one response is expected (with a number of bytes less than the Buffer
Size). After data is transmitted to the serial port and the Response Timer
times out with no data or after one response is received and returned to the
network client, the Terminal Server does not read any more serial data until
the next request.

Modbus Mode
Select the mode of operation, if Modbus protocol translation is required.
Modbus protocol translation is only needed if the network client is sending
Open Modbus/IP protocol requests. Translation is not needed for other
types of data or if the standard serial Modbus (ASCII or RTU) is
encapsulated within the TCP/IP requests. Options available are:
None: This is the normal option for most applications.
Open Modbus to ASCII: Converts Open Modbus/IP protocol requests to
serial Modbus ASCII protocol, and converts the ASCII response to an Open
Modbus/IP response.
Open Modbus to RTU: Converts Open Modbus/IP protocol requests to
serial Modbus RTU (Binary) protocol, and converts the RTU response to an
Open Modbus/IP response.
Serial Driver
Select whether to use the Native Linux (ttyS) serial driver or the ACSCOMM
driver. The ACSCOMM allows for half-duplex RS-485 communication and
can provide somewhat better handling of hardware flow control if required.
Broadcast Only
Select Yes to only send to the serial port. This option allows the network
computer to send data to the serial port without waiting for a response. The
Response Timeout and Duplex mode are ignored.
Demark IP Packets
If a large network packet is sent to the ZyWAN-G9 and gets broken up over
the network, the fragments can sometimes arrive at slightly different times.
Each packet is sent to the serial port, but if the time difference is too great,
the serial device may not react properly. Set this value to Yes to allow
delayed IP packets to be put together before sending to the serial port. The
value for Demark Timer is used to specify the time to wait for additional IP
data. Set this value to No if this feature is not needed.
Echo Cancel RS-485
This option is used when the internal (COM4) or an external RS-485
converter is used in half-duplex mode. Set this option to Yes to block the
reception of echo bytes on the serial port which get echoed back from the
RS-485 device.
Print Server
This option is used when the Terminal Server is used as a print server to a
serial printer. Setting this option to Yes causes the Terminal Server to
operate in Print Server mode. The Terminal Server absorbs as much IP
data as it can within the available memory and sends data to the serial port
until it is all delivered, regardless of whether the host disconnects.
When this option is set to No (default mode), if a host disconnects and data
is still in the Terminal Server buffer, the remaining data is discarded and will
not be sent to the serial port.
Number of Servers
Enter the number of simultaneous clients which can connect to this Terminal
Server simultaneously. Values must be between 1 and 8.
If this is set to 1, the Terminal Server is pre-emptive. This means that if a
second client connects to the port, an already-connected client is
disconnected.
With Number of Servers set to 2 or greater, any further connections are
blocked when the number of simultaneous connections have been made.
Password
Enter a non-blank field as a password for the Terminal Server, if desired.
The password must be no longer than 15 characters. When this is set,
making a connection to the Terminal Server port returns a prompt for
„Password‟. If the correct password (case-sensitive) is not entered within a
minute, the connection is dropped.
Buffer Size
Enter the maximum number of bytes (between 1 and 4095) which are
allowed in a response to a network client. (The actual number of bytes sent
may be less if the Demark timer times out before the serial buffer is full.)
Demark Timer
Enter the maximum time (in milliseconds, between 10 and 30000) the
ZyWAN-G9 waits for inactivity on the serial port before sending a response
to the network client, if at least one byte has been received.
Response Timeout
This option only applies if the Duplex option is set to Half Duplex.
Otherwise, this field is ignored.
Enter the Response Timeout (in milliseconds, between 10 and 30000). For
simple request-response networks (half-duplex), the request from a network
client is sent to the serial port. If no serial response is received within the
Response Timeout, the Terminal Server does not read any more serial data
until the next request and the serial port is released.

depending on the size and number of updates that have to occur. Do not remove power or
perform a Linux command line „reboot‟ until the updates have completed.
In some cases, the ZyWAN-G9 will be required to reboot automatically in the middle of its
update process. If this occurs, it will continue installing additional files after the reboot. Do
not reboot the ZyWAN-G9 or remove power while software updates are installing, or else
unpredictable results may occur.
Chapter 10 Update
The following screen capture shows the Update tab.
The Update tab on the Web interface provides one method to update the ZyWAN-G9 firmware to a
later version. See the later section, Updating Using WinSCP on page 100, for another recommended
method of updating, especially for systems where the default network is a cellular or private network.

http://network_address/pathname
(HTTP download from ip_address which must be an
HTTP server, with the files existing in pathname)
--ftp-user=username --ftp-password=password ftp://ip_address/somepath
(for FTP download from ip_address/somepath, using
username and password)
Note:
The default URL address listed above should only be used with a standard ZyWAN-G9
software version, because only the main branch of “standard” releases is stored in that
location. Standard G9 will have a “Current Software Version” on the Status page with a
name something like: ZyWAN-G9_release-x.y.z
Customer-specific software releases will have a differently named software version, and
may have entirely different sets of update files. Therefore, trying to apply the standard
ZyWAN-G9 updates to customer-specific systems is likely to cause unpredictable results.
Take care to enter an appropriate Update URL before clicking the Update ZyWAN button.

Note:
If the ZyWAN-G9 is rebooted in the middle of an update, there is a possibility that software
corruption of the file system can occur. Make sure the update process is finished before
removing power or rebooting.
Updating Via the Web Interface
In the Update URL field, enter the network address URL (Uniform Resource Locator) from which an
update file may be downloaded. The address must be accessible through the default network
interface of the ZyWAN-G9 and must point to a file server location containing update files for the
ZyWAN-G9. Some examples of addresses which could be used are:
If the Update URL field is left blank, the following default URL address will be used:
http://files.eurotech-inc.com/ESF/product_updates/eurotech/zywan_g9
The server location must contain the latest versions of the ZyWAN-G9 software release files, such as:
When the Update Zywan button is pressed, the files are downloaded and installed. After the update is
complete, the ZyWAN-G9 will be rebooted automatically if needed.
If more than one update is available at the update site, all updates will occur in numerical order, one
after the other. This may require some time to complete, and may require multiple reboots in between
updates. The Check Update Status button may be clicked whenever the ZyWAN-G9 is available on a
network address, to check on the status of an in-progress update. A prominent warning message will
also be given on the Status and Update tabs, to warn the user that a software update has started but
not yet completed.

Updating Using WinSCP
Some version updates for ZyWAN-G9 could be fairly large. For this reason, it may not be
recommended to use the Update Web interface described in the previous section, because of the cost
or length of time required to load files over a cellular network. There may also be cases where the
ZyWAN-G9 cannot connect to an update site because of limitations on its network access.
The following method describes how to load the ZyWAN-G9 update files locally over Ethernet or WiFi
and to install them manually.
See the section SFTP/SCP Client (WinSCP) on page 28 for information on installing the WinSCP file
transfer program. This program provides a free and secure means of loading the required files,
although other programs may be used which support the SFTP or SCP protocols.
Determine the current software revision by viewing the Status tab of the ZyWAN-G9 Web configuration
page. The following screen capture shows an example indicating a ZyWAN-G9 at software revision
level 2.0.0.
The required files can be obtained upon request from Eurotech, or they may be downloaded from
http://files.eurotech-inc.com/ESF/product_updates/eurotech/zywan_g9 (standard releases only, not
customer-specific).
