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. 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
