RS-485 / RS-422 wiring diagrams
When connecting RS-485 or RS-422 devices in a multidrop configuration, there must
usually be a 120Ω termination resistor at one or both end devices in the network, but
NOT on any devices in the middle of the loop.
In RS-485 or RS-422 systems, the ground connection is optional. It is typically used to
connect the cable shield for a shielded, twisted pair cable. In the ZyWAN, the RS485/422 ground is common with the RS-232 grounds, but is isolated from the metal
case. In order to avoid ground loops, connect the cable shield to the RS-485/422 GND
AT ONLY ONE POINT in the network.

After logging into the ZyWAN, type the command ifconfig eth1 at the command
prompt. This shows the current network address which has been assigned to the
ZyWAN by the network:
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 from obtaining its address. An address can be
manually set if necessary, by issuing the following command:
ifconfig eth1 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).

If using the ZyWAN 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,
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, depending on the test being performed.
If the ZyWAN is acting as a DHCP Server to the PC and is configured to serve the
DNS addresses, these should be displayed in the ipconfig settings.
Log into ZyWAN COM1 for diagnostics
When using a null modem serial cable connected to COM1, as described in Initial
configuration over a network on page 23, several commands can be issued to the
ZyWAN to diagnose network configuration or operation.
To check network configuration or availability:
ifconfig
To set a temporary network address on an interface:
ifconfig eth1 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).
To send a diagnostic message to another device on a network:
ping address
where address is the numeric or named address of another device.
Press Ctrl-C to stop the ping.
To check the route table of the ZyWAN:
route -n
To make a TCP/IP connection to a port on a device:
nc ip_address ip_port
where ip_address is the device address on the network or 127.0.0.1
for the ZyWAN itself,
and ip_port is the network port.
Check with network administrator
If you are still unable to get the ZyWAN to connect to an existing network, check with a
network administrator for additional support.

ZyWAN-EVDO options
On the ZyWAN-EVDO, the Cellular tab looks like this:
EvDO modem modules contain the account activation information stored in the modem
rather than a removable SIM card. Generally this is the responsibility of the customer
to activate a module to put it into service. This can also be used to switch to an
alternate account on the same module. These operations can be done via the Web
configuration page.
The manual activation process for EvDO consists of the following steps:
1
Obtain the activation code (Master Subsidy Lock) and other NAM profile account
information for a data account on an EvDO network.
2
Configure the modem module with the NAM profile information. On the ZyWAN,
this is done by filling in the correct fields and clicking the Set NAM Profile button.
3
Provision the account profile to be active on the network. On the ZyWAN, this is
done by filling in the correct fields and clicking the IOTA Provision button. IOTA
stands for the ‘Internet Over-the-Air’ protocol. This must be done in an EvDO
coverage area in the service provider’s network area.
The EVDO network provider must be specified at the time of order so that the
correct modem can be installed from the factory, so this is not given as a user
configuration option. The service provider can be viewed on the Status page,
see Status on page 71 for more information. Typically, the provider is Sprint or

The best time server to use is one available on a local
network, if available. This avoids using public Internet
resources and gives more accurate time. The second best
option is to use a time server which is located on the
Internet somewhere close (small roundtrip time). Otherwise,
some possible addresses are: 0.pool.ntp.org, 1.pool.ntp.org
and 2.pool.ntp.org (these addresses point to three randomly

Field/Option
Explanation
Server IP Address:
Enter the numeric IP address or FQDN to which the UDP

of the host computer, which should 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 receive the GPS data over UDP. Port numbers should
be a number between 1 and 65535. If the ActSoft Format is
used, the port number should generally be 8502.
Request Interval:

how often the GPS data is obtained from the GPS receiver.
Multiple GPS positions can be collected and buffered, to be
sent all together as determined by the Send Threshold
(below), 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 shall not be sent until the
specified number of GPS positions have been obtained from
the GPS receiver.

Explanation
Unit ID:
Enter the unit ID which identifies the GPS data from this
ZyWAN 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-GPRS: The Unit ID is a unique 10-character
serial number, with format to be specified by ActSoft.
For ZyWAN-IDEN: The Unit ID is the 10-character modem
serial number.
For ZyWAN-GPRS: The Unit ID is a unique 10-character
serial number, with format to be specified by ActSoft.
It is essential to observe that this modem serial
number is entered correctly. If not, and if duplicate
ID’s are reporting from any other device, both
customers may suffer loss of data and an
interruption of service.
Enable Cache?
Select Yes to enable caching of GPS data. When caching is
enabled, the ZyWAN stores 100 positions in non-volatile
memory. After this cache is filled, the oldest positions are
discarded. Once the network connection is re-established,
positions in the cache are transmitted in a first-in, first-out
order.
When Enable Cache is set to Yes, a UDP acknowledgement
is required from the host computer, which allows the ZyWAN
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
network address must be accessible to host
computer, since the host must initiate a one-way
UDP acknowledgement message to the ZyWAN. If
the acknowledgement is not received (due to
network problems, etc.), the ZyWAN caches the
GPS points based on the Request Interval and
Send Threshold parameters (above), and continues
to try sending the next point every 10 seconds.
When Enable Cache is set to No, a UDP acknowledgement
is not required. The ZyWAN simply sends out the GPS
points and discard 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 shall be
transmitted using the User Datagram Protocol (UDP). If caching is enabled, the
ZyWAN 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 shall be retransmitted. This process shall continue indefinitely.
The ACK should be 3 ASCII characters (0x41 0x43 0x4B).
The position message is defined below. 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 shall

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

operate similar to a Carrier Detect (CD) output from a dial
modem, which is asserted after a data connection is
established.
Buffer Size
Enter the maximum number of data bytes (between 1 and

may be less if the Demark Timer (below) times out before the
serial buffer is full.
Demark Timer
Enter the maximum time (in milliseconds, between 10 and

before sending whatever serial data has been received.
Reconnect Delay
Enter the length of time (in seconds, between 1 and 65535) the
Terminal 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, with its Matching Dial String set
to an empty field.
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, with its Matching Dial String set to an
empty field.
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.
This 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 does not make an
outbound Terminal Client connection. See Matching Dial String
(below) 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

Demark IP Packets
If a large network packet is sent to the ZyWAN 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 RS485
This option is used when the internal (COM3) or an external RS485 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.

ZyWAN User Manual
Configuring the ZyWAN
Field/Option
Explanation
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 send 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 data is discarded and not 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 alreadyconnected client is disconnected. With Number of Servers
greater than 2, 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 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.

ZyWAN User Manual
Configuring the ZyWAN
The Serial Ports Table is part of the Terminal Server configuration. At least one row
must be configured in the Serial Ports Table for it to work properly:
The following buttons are available:
Button
Explanation
Insert Row#
Each row of the Serial Ports Table contains the definition of a
serial port to use for this Terminal Server configuration. One
Terminal Server may send data received from the network client
to multiple serial ports simultaneously. In order to insert a row in
the table, enter a number in the box between 1 and one greater
than the highest number of rows. Then click the Insert Row#
button to insert a blank row. This row must be filled in with all data
required.
Note that when adding or deleting rows of a Serial Ports Table,
make sure to click the Insert Row# or Delete Row# buttons
within the brown section of the Serial Ports Table, not the buttons
at the very bottom of the main table.
Delete Row#

In order to delete a row of the Serial Ports Table, enter a number
in the box between 1 and the highest number of rows. Then click
the Delete Row# button to delete the row. Once a row is deleted,
it cannot be restored without inserting a row and entering the data
again.

ZyWAN User Manual
Configuring the ZyWAN
The following options are available for the Serial Ports Table. At least one row of the
Serial Ports Table is required for the Terminal Server to operate.
Field/Option
Explanation
COM Port
Select the serial COM port to which the Terminal Server data is
sent.
Make sure this COM port is not configured for
another service in the ZyWAN. Otherwise, both
services may conflict for the port and not operate
correctly.
It is possible in some applications to configure two
Terminal Servers to use the same COM port. In
order for this to work, the Demark option must be
set to Half Duplex or Broadcast. In Half Duplex
mode, the clients connecting to each port may
need to wait much longer for a response, since the
Demark and Response Timeout times for all
connections are observed, in the order that the
requests are received from each client.
Baud Rate
Select the baud rate to use for the Terminal Server port. Baud
rate options range from 1200 to 115,200 bps.
Data Bits
Select the number of data bits to use for the Terminal Server
port. Options are 5, 6, 7 and 8.
Parity
Select the parity to use for the Terminal Server port. Options are
None, Odd, Even, Mark, Space.
Stop Bits
Select the number of stop bits to use for the Terminal Server
port. Options are 1, 1.5 and 2.
Flow Control
Select whether to use hardware flow control for the Terminal
Server port. Options are None and RTS/CTS (hardware flow
control).

Status
The Status tab looks like this:
The Status tab includes several items which give the current status and hardware
configuration. The hardware configuration is done in factory configuration and is
provided here for information. See ZyWAN model numbers, page 9, for information on
the ZyWAN model numbers based on hardware configuration.
The screen offers the following fields and options:
Field/Option
Explanation
Hardware Model
The Hardware Model gives the type of cellular modem installed.
Options are indicated as: gprs, iden and evdo.
EVDO Provider
Since the EvDO cellular provider has to be specified with the
modem provided with the ZyWAN, this is set as part of the
factory configuration (applies only to ZyWAN-EVDO models).
Options for EvDO provider are: Sprint.
GPS
This option indicates whether or not GPS hardware is installed.
802.11B
This option indicates whether or not an 802.11b WiFi module is
installed.
Last COM Port
This option indicates what is the last available COM port on the
ZyWAN, which is used in all other configuration menus where a
selection of COM ports is allowed. Typically this is COM3.
COM3 Type
The COM3 port may be factory configured to be either RS-232
or RS-485/422. Options are indicated as: RS-232 or RS-485.
