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.
