Wiring and configuration information for this sync extension is described under Wiring to Extend Network
Sync.
W ir ing t o Ext end Net w or k Sync
The following procedure can be used to extend network sync by one additional hop, as described under
Passing Sync in an Additional Hop. When a co-located module receives sync over the air, the co-located
modules can be wired to pass the sync as follows:
1. Connect the GPS Utility ports of the co-located modules using a sync cable with RJ-11 (for 450) or
RJ-45 (for 450i/450m) connectors.
2. Set the Sync Input parameter on the Configuration page of the co-located AP or BH timing master
to AutoSync.
3. Set the Device Type parameter on the Configuration page of the co-located AP or BH timing
master to Remote.
4. Set the Sync Output to Aux Port parameter on the Configuration page of the co-located AP or BH
timing master to Disabled.
5. Set the UGPS Power parameter on the Configuration page of the co-located AP or BH timing
master to Disabled.
6. Set the Frame Timing Pulse Gated parameter on the Configuration page of the co-located SM or BH
timing slave to Enable.
Note
This setting prevents interference if the SM or BH timing slave loses sync.
