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 iN2 unit cannot be placed on that corner, so an iN3 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 iN3 unit as well as the iN2 unit on the same
phase on the opposite side of the intersection.
From the Main Menu, select PBS Configuration, then select Wireless Sync.
Ena
ble this function by tapping the ‘Wireless Sync’ switch at the top of the screen.
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 iN2 unit, but it does not need to
be enabled on the iN3 unit if there are no button wires connected to the large terminal
block.
Note: In iNavigator (iN2/iN3) units, 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.
