Format mode, and for Arcom Format where the Enable Cache option is set to Yes .
The following table lists the fields and options offered.
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 10-
character 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 re-
established, 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.
