RF system – same as on AC.
Test switch
Non-operational
Test LED – bi-color Red/Green
Indicates status of last test – see function table above
Status LED – bi-color Red/Green
See function table above
RFoperation
Three encoders
Encoder one actually sets one of 16 RF channels
Encoder two and three sets an 8-bit address.
The user just treats this as a two-digit ‘channel code’, in this case the same as
the floor number.
Depending on system testing, we may change the functionality (for example,
keep all traffic on one RF channel…) so it’s better not to expose this detail to
the user
A fixture will respond to motion events from fixtures on the same floor, or
one floor above or below.
Uses CC430 with integrated CC1101 radio
Implement simple broadcast flood meshing
Packet has a hop-count field, we have a fixed system hop-count 5
max.
When radio rx’s a packet it decrements the hop count and
retransmits the packet unless the hop count is 0.
Use collision avoidance built into radio
Proprietary XRF packet format
Allow for future options
Allow for gathering status from fixtures
Allow for use of broadcast address for queries
Broadcast ‘groups’ are the floor number settings
Motion events are broadcast to cut down on-air time
Flexible ‘report’ packets, i.e. power status
CC430 has built in UID, use it for our network UID.
Production test support
serial port status output
