Advanced options - HMT140

These advanced parameters (Options > Advanced Options) are applied each time an Update function is performed (available in HMT140 Utility version 1.1.4.0 and higher).

• Extended Transmit, Log Periods and HMP Polltime: Adds an additional transmission, logging and polling time periods on the Sensor tab. These additional periods are meant to be used for testing, evaluation and demonstration of HMT140 and, if used regularly, can have a severe impact on battery life.
• Log Conversations: When this option is selected, HMT140 Utility will capture the conversation between HMT140 Utility and 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, HMT140 will cache its IP address assigned from the DHCP server until the DHCP lease time has expired or HMT140 is power-cycled. If not selected, HMT140 will request an IP address each time it attempts to contact the host.
• ARP Caching: When this option is selected, HMT140 will store and keep a list of IP/MAC relationships. If not selected, HMT140 will rebuild the IP/MAC relationships with every attempt to contact the host.
• DNS Caching: When this option is selected, HMT140 will cache the IP address that results from the DNS lookup of the Destination hostname. HMT140 will keep the destination IP address until either the DHCP lease time expires or HMT140 is power-cycled. If not selected, HMT140 will request a DNS lookup of the Destination hostname each time it attempts to contact the host. This setting is not recommended for most monitoring systems.
• Allow Channels 12 and 13: Enable the use of channels 12 and 13. This option should only be used in regions in where these channels are not restricted.
• Connect Window: Set the amount of time in seconds (3 to 8 seconds) that HMT140 will attempt to associate and authenticate to an access point or a wireless 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 1 to 54 Mbit/sec. The lower the data rate the longer range HMT140 will have. The 802.11b data rates are: 1, 2, 5.5 and 11. All other data rates are 802.11g data rates. An access point or wireless router may be configured 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, HMT140 Utility will force the Destination Port to use this entered number. Use this feature to force the Destination Port to another value other than the default 6767.
