| MSG-2191 Infrared Radio Beacon Checker |
 |
|
|
The MSG-2191 is a signal generator designed for generating simulation signal of VICS' Infrared Beacon and Radio-wave Beacon; it is used for testing Infrared/Radio-wave Beacon receivers. This unit is operated from a PC through USB interface by using the attached application software. Also, users can input their Infrared Beacon data and Radio-wave Beacon data to this unit from PC. A special designed antenna for transmitting/recovering beacon is attached as standard. Note: The application software is not capable of creating and editing data.
* In VICS (Vehicle Information and Communication System), Infrared Beacon (at Main trunk roads) and Radio-wave Beacon (at Expressways) are used for providing traffic congestion information to vehicles and collecting traveling time from vehicles. |
| ■ |
This unit has six Records for each Infrared data and Radio-wave data. Data from PC can be input into Record No. 1 to No. 5. (No. 0 is a fixed data for confirmation.) |
| ■ |
In case of the Radio-wave Beacon, the level can be set to be changed automatically to obtain such an image as a vehicle approaches to the Beacon and then, goes away. |
| ■ |
In case of the Infrared Beacon, down link and up link (two-way communication) tests can be performed. |
| ■ |
When turn power switch off, setting of this unit is saved by battery backup function. |
| ■ |
When turn power switch on, self-test function detects abnormity of this unit. |
