Remote Hub Connection
failed
 Description: An attempt to connect to a remote hub failed at UNIX time of
<timestamp>.
 Recommended Action: Check network cable and whether remote hub is
functioning.
 Message Type: This event packet will be sent after every retry to connect with
the remote hub and will persist until a connection can be established.
 Message Format:
Dart: D,0,0,0,0,0,timestamp,DpacketID,‘Error: Remote hub

of <timestamp>.
 Recommended Action: None.
 Message Type: This event packet will be sent once when an attempt to connect
with the remote hub succeeds.
 Message Format:
Dart: D,0,0,0,0,0,timestamp,DpacketID,‘ Remote hub connection

Hub Sync 100M Clock error
 Description: Clock sync failed between hubs that share receivers, at UNIX
time of <timestamp>.
 Recommended Action: Check the RJ45 cable between hubs are connected in a
daisy chain. There can by only one master hub supplying the clock in a chain of
connected hubs.
 Message Type: This event packet will be sent every minute until clock sync is
established between hubs.
 Message Format:
Dart: D,0,0,0,0,0,timestamp,DpacketID,‘ Error: Hub sync 100M
clock error’
Hub Sync 100M clock good
 Description: Clock sync OK between hubs that share receivers, at UNIX time
of <timestamp>.
 Recommended Action: None.
 Message Type: This event packet will be sent once when clock sync is
established between hubs.
 Message Format:
Dart: D,0,0,0,0,0,timestamp,DpacketID,‘ Hub sync 100M clock
good’

D-packets possible during operation
Reference tag lost
 Description: A reference tag with tag ID <refTagID>, configured to be at
location (x,y,z), has lost signal for more than 20 seconds. The <battery>
represents the tag battery level at the last detection time, and <timestamp> is
the UNIX time (i.e. the number of elapsed seconds since January 1, 1970, UTC),
at which the reference tag signal was last detected.
 Recommended Action: Verify the reference tag is present and not damaged.
 Message Type: This warning packet will be sent only once when the reference
tag has not been detected for 20 seconds
 Message Format:
Dart: D,refTagID,x,y,z,battery,timestamp,DpacketID,‘Error: reference tag lost’
