Important:
These additional periods are meant to be used for test-
ing, evaluation and demonstration of the HMT140 and,
if used, can have a severe impact on battery life.
Log Conversations:
When this option is selected, the
HMT140 Utility will capture the conversation between
the utility and the HMT140 and place it in a file called
OutputLog.txt. To locate the file, go to the
Help
menu,
select
Utility Folder Paths
, and then
Explore Data
.
DHCP Caching:
When this option is selected, the
HMT140 will cache its IP address assigned from the
DHCP server until the DHCP lease time has expired or
the HMT140 is power-cycled. If not selected, the
HMT140 will request an IP address each time it attempts
to contact the host.
ARP Caching:
When this option is selected, the HMT140
will store and keep a list of IP/MAC relationships. If not
selected, the HMT140 will rebuild the IP/MAC relation-
ships with every attempt to contact the host.
DNS Caching:
When this option is selected, the HMT140
will cache the IP address that results from the DNS
lookup of the Destination hostname. The HMT140 will
keep the destination IP address until either the DHCP
lease time expires or the HMT140 is power-cycled. If not
selected, the HMT140 will request a DNS lookup of the
Destination hostname each time it attempts to contact
the host.
Connect Window:
Set the amount of time in seconds
(three to eight seconds) that the HMT140 will attempt to
associate and authenticate to an access point or a wire-
less router (this includes the time to obtain an IP address
from a DHCP server). The default rate is 5 seconds.
Data Rate:
The default data rate is 1 Mbit/sec. and can be
set from one to 54 Mbit/sec. The lower the data rate the
longer range the HMT140 will have. The 802.11b data
rates are: 1, 2, 5.5 and 11. All other data rates are 802.11g
data rates.
Note:
An access point or wireless router may be config-
ured to exclude 802.11b data rates.
Override Destination Port:
Leave blank to not use this
feature. If a number (1 to 65535) is placed in this field,
