Read point

The read point settings can be configured using this page. The current state of the read points can also be viewed in this page.

• Antenna Status - Shows the status of the read points on this reader. There can be three possible state of a specific read point.

.        Connected - Read point is enabled and an antenna is connected to the port. (Shown using the green button).

.        Not Connected - Read point is enabled, however no antenna is connected to the port. (Shown using the red button).

.        User Disabled - Read point is disabled by the user. (Shown using the yellow button).

Clicking on the status button of a read point will allow the user to see / change the selected antenna's configuration.

• Refresh Interval - Allows the user to set the refresh interval (in seconds) to update the readpoint status on this page. The minimum value of the refresh interval is 10 seconds while the maximum value allowed is 86400 seconds.
• Maintenance mode - Places the reader in maintenance mode in order to intermittently drive PWR, ACT and STAT LEDs to enable easily locating the reader. Also enables quick reporting of Antenna status by setting the refresh interval to 2 seconds. Note that user is not allowed to modify the refresh interval in this mode.
• Choose Read point - Allows choosing a specific readpoint whose configuration is displayed.
• Description - User specified description of the read point. Accepts alpha numeric characters with a maximum size of 32 characters.
• User Configuration - Setting allows the user to enable or disable a specific read point. Disabling a read point ensures that no RF operation are performed using the antenna connected to the specific port.
• Air Protocol - Shows the list of air protocol supported by the read point. Currently only EPC class1 "GEN2" air protocol is supported.
• Cable loss(dB/100 ft) - Allows the user to specify the cable loss in terms of dB per 100 feet length for the antenna cable that is used to connect this read point port to the antenna. This information can be obtained from the specification of the antenna cable. The default value for this is 10. Setting this and the cable length to non zero values allows the user to compensate for the RF signal loss in the cable due to attenuation by specifying an appropriate increase in the transmit power for this read point.
• Cable length(ft) - Allows the user to set the cable length in feet of the physical cable used to connect the read point port to the antenna.The default value for this is 10.
• Set Properties - Clicking on "Set Properties" button sends the user changes to the reader.
