5 Connecting multiple hubs
The Hubs can be connected in Daisy chain configuration to synchronize their clocks which will
enable hubs to use receiver from other hubs whose clocks are in sync with each other. The front
panel of the Hub has 2 RJ45 connectors that are used for clock synchronization marked as
CLOCK IN and OUT. There are 8 other RJ45 connectors that are used for connecting receivers,
(marked numbers 1 through 8 under RECEIVERS) to the hub.
The following sections guide you through connecting the Hubs:
 In a daisy chain to the Hub (on page 15)
In This Section
Connecting multiple Hub together in clock sync mode ................. 17
Use care to only connect Receivers to the Hub port connectors on the front panel and to only connect LAN
cables to the Ethernet port connector on the rear panel and use CLOCK IN and OUT for hub clock synchronizing.
Improper connections may result in damage to Receivers, Hub or external LAN equipment.
For best result the Hubs used for clock synchronization and receiver sharing should be located on the same
LAN subnet.
Connecting multiple Hub together in clock sync mode
You can connect the CAT 5E power and data cables between the Dart RTLS Hubs in a daisy
chain.
To connect Hubs in a daisy chain configuration:
1 Plug the RJ45 Ethernet connector of the first CAT 5E cable into Hub#1 clock out port marked
CLOCK OUT on the front of the Dart RTLS Hub.
2 Connect the other end of the CAT 5E cable to the RJ45 connector marked “CLOCK IN” of
Hub #2.
3 Connect a second CAT 5E cable to the RJ45 connector marked “CLOCK OUT” of Hub#2.
4 Connect the remaining end of the second CAT 5E cable to the RJ45 connector marked
“CLOCK IN” of Hub $3.
5 Continue to connect additional Hubs as required to the chain in series.
