IRIS

Intelligent Roadway Information System


GPS

A GPS (global positioning system) receiver allows device locations to be tracked and automatically updated with the nearest roadway and direction. They can be created, edited and deleted with the GPS form.

Setup

Select View ➔ GPS menu item

Each GPS must be associated with a controller on an appropriate comm link. Several [protocol]s are supported:

Protocol IO Pins Notes
NTCIP 2 same controller as DMS or weather sensor
RedLion 1 controller on separate comm link for modem (tcp port ????)
SierraGX 1 controller on separate comm link for modem (tcp port 9494)
Sierra SSH 1
Field Description
Notes administrator notes, possibly including hashtags
Geo Location device location name (same as device name)

To check a GPS device, select the device (DMS, etc.) and open its Properties form. On the Location tab, there are widgets for querying the GPS status.
