Expansive I/O For Tolling

Overview

Sealevel partners with an IT services and integration company that specializes in solutions for the tolling and transportation industries. The company services several of the top 15 toll authorities across the United States, processing billions of toll transactions per year.

The company’s roadside solutions include electronic tolling, dynamic pricing, express lanes, and asset management. As a result of reliability and availability issues with other vendors, they designated Sealevel as their primary source for digital I/O in support of a variety of tollbooth applications. In addition to a highly reliable solution with long-term availability, the customer needed a product that could trigger a wide variety of technology including cameras, bill acceptors, license plate readers, and gates. The requirements expanded to include the identification of vehicles and violations.

The Solution

Sealevel’s team specified the SeaI/O 463E DAQ Module to meet the application’s extensive – and growing – needs. This Ethernet to digital I/O interface provides 96 channels of buffered drive digital I/O. Using standard, 50-in IDC ribbon cables, the customer was able to connect multiple relay racks for further control and automation of the various sensors and peripherals. Initially deployed to trigger the various peripherals, the 463E was able to also address the tolling-specific identification needs due to its capacity.

With Modbus TCP protocol compatibility as well as the Sealevel SeaMAX API, the customer was able to achieve quick communication and control. And the SeaMAX software driver simplified installation and allowed for flexibility with Microsoft Windows and Linux.
