4.3.2 Receiver ID
The Receiver ID is automatically generated by the plug-in for new Readers, but it may be
changed at a later date. The Reader ID must be unique across the network of Readers.
Once the Reader ID has been programmed into a Reader, it may be moved in its location
amongst the other Readers on the network and still retain its identity and associated
configuration.
4.3.3 Location and Name
The Location and Name fields are for your own identification of the Reader at this time – no
HomeSeer
devices are created using these names, but the location and name fields follow
the HomeSeer
nomenclature in case future revisions create devices to work with the plug-
in.
4.3.4 RSSI (Received Signal Strength Indicator)
The RSSI indicates the strength of the signal from a Tag when it is received at a Reader.
This configuration setting for the Reader determines the MINIMUM value of RSSI before the
Reader will acknowledge the Tag’s signal. For example, a Tag that is very close to a Reader
may send a signal that is received by the Reader measuring an RSSI of 130. When that
same Tag is 350’ away from the Reader, the measured RSSI of the received Tag signal may
only be 50. If the Reader RSSI setting is 60, the Tag signal from 350’ away will not be
acknowledged by the Reader, whatsoever. Although the various Reader and Tag
combinations will have different characteristics for RSSI, the current R500HA Readers and
Tags generally have RSSI values between 30 and 130. Readers that you wish to configure
for the maximum range should be set to zero, and anything 30 or higher will begin to affect
the range at which Tags are detected.
4.3.5 GAIN
The receiver GAIN setting sets a characteristic of the receiver’s radio that affects the range
of the Tags it can “hear.” If you are seeking the highest possible range of Tags to be
received, set this to HIGH, otherwise set it to LOW , change to HIGH only if you cannot get
the range you seek for the application of the Reader.
4.3.6 Min Timeout (Minimum Timeout and Additional Timeout)
When a Reader no longer hears a Tag signal, it is considered “absent” from the Reader. In a
single-Reader, single-Tag system, updates from the Reader will occur approximately at 0.8
second intervals, but updates increase dramatically with multiple Readers and multiple
Tags. In a large system, a Tag signal may not be received for a few seconds, so the timeout
parameter helps prevent the plug-in from assuming a Tag is absent when it actually is not.
When the last time a Tag has been “seen” and the current time are different from the total
timeout period (or more), then the Tag is removed from the list of Tags associated with that
Reader, and the “Tag is absent from Reader” trigger (if there is one used in the system) is
raised. The total timeout period consists of the minimum timeout, which is set for each
Reader (this configuration setting) and the additional timeout that is configured with each
Tag. This setting is in seconds, and the minimum value for this setting is 2 seconds.
