Wireless Sync
Considering a scenario where a crossing on one side of the intersection does not have button wires, but does have a ped
head, an iNS2 unit cannot be placed on that corner, so an iNS3 unit must be used. In this instance, there is no method of
communicating a button press or ped call through a wired connection. The PBS has the capability to communicate via
BLE from PBS to PBS to convey ped call information.
The wireless sync function provides a link between PBSs on the same PED phase such that a button press on one unit
enables the Walk and Clearance sound on the other unit. Both standard and extended push status is transmitted.
Enable the wireless sync feature on the iNS3 unit as well as the iNS2 unit on the same phase on the opposite side of the
intersection.
Enable this function by enabling
the ‘Wireless Sync’ switch.
The Intersection ID is used to prevent any possible interference between nearby intersections which are also using this
feature. Tap the ‘Intersection ID’ box and enter a number (up to 9 digits) and tap ‘Save’. Any number is acceptable as long
as it is different from that used on any nearby intersection. In the same manner, enter the PED phase number for this
PBS. Note: The Intersection ID is shared between the Wireless Sync feature and the PedApp feature. The ID can be
changed in both the Wireless Sync settings page and the PedApp Intersection Info screen, but they refer to the same ID.
When the Remote Ped Call option is enabled, if that unit receives a button push indication from a Wireless Sync
transmission, then it will also cause a Ped Call indication to the traffic cabinet. Enable the Remote Ped Call feature on the
iNS2 unit, but it does not need to be enabled on the iNS3 unit if there are no button wires connected to the large terminal
block.
Note: In iNavigator units (iN2/iN3), when the Wireless Sync feature is active, the PBS will not accept Bluetooth
connections via an iOS device or PC. However, 5 seconds after an Extended Push, the PBS will accept connections until
the start of the next Clearance cycle. iNS units do not have this limitation.
Wireless Sync is compatible between iNS and iN family products.
