• Error-free data exchanges are ensured with an auto-correcting protocol.
  
• The PC produces diagnostic messages reporting the proper operation of the communication link.
  
• The IR-20 incorporates a small microprocessor.
  
• Up to eight IR-20's can be used on the same standard COM port of a PC for multiple lane operations.
  
• Status lights simplify system diagnostics.
  
• Compatible with the IRDA (Infrared Data Association) format: the IR-20 can communicate via the infrared link available on most new laptop computers and Palm devices.
  
• Our DC-10 Data Collector can also be used with an infrared link.

Installed on-board the vehicles and in the service dock areas of the garage, the units transfer passenger-counting data to the garage computer and upload the on-board computer’s software when necessary.

The IR-20 comes with the optional IRMAN utility. IRMAN is a practical software tool that keeps track of vehicle downloads and helps identify errors or vehicles that have a saturated memory.
