MARC controllers are designed for on-street operation and meet NEMA TS1-1989 and NEMA TS2-1992 environmental standards for actuated controllers. The friendly, English language-based user interface allows full system access from the on-street master or from an optional central office site via ITS’s MARCNX Windows based software. The remote access allows master and local intersection programming and monitoring, providing improved programming efficiency while reducing errors.

Hardware Design
MARC controller units are designed for efficient operation and ease of maintenance. The metal chassis offers ready access to boards for testing without disassembly. MARC units have minimum components for maximum reliability. Maintenance and troubleshooting is facilitated using the internal diagnostic program.
Displays & Memory
The MARC controller unit display provides true visibility
into program entries, system data and status. Related parameters are visible simultaneously.
EEPROM technology is used to retain all system timing and control parameters to insure the accuracy of traffic control parameters even during power outages. No
batteries are required for retention of traffic system
parameters. Clock Time and Event Logging functions use RAM memory with long life battery support.
Programmability
The MARC controller unit offers on-site programming via the front panel keyboard and LCD display or upload/
download.
Programming is easy using the English Language Menus. Within menu, each parameter may be viewed, and a cursor movement for that parameter makes any changes easy and
error free.
System Management
MARC provides the user system configuration and/or operation controls including:
- Add/Delete Controllers and System Detectors
- Enable Traffic Responsive Mode
- Assign Intersections to Groups
- Assign System Detectors to Computational Channels
- Assign Computational Channels to Pattern Select
Routines
Front panel access is permitted to each local controller from the master location or from the optional central office for modification of intersection parameters. Special and/or standard detectors can be assigned as system sampling detectors for use with Traffic Responsive computational channels or for historical activity logging.
Security
MARC permits unrestricted viewing of system parameters,
data or reports but requires a user-specified security code entry for data alteration. The code can be disabled for perpetual access capability.
Diagnostics
An internal diagnostic program enhances the maintenance and troubleshooting of the MARC controller. Automatic diagnostics begin at power up and continue as long as
the unit is operating. ROM, RAM and Processor checks are included. Other features of the Resident Diagnostics Program provide total indication of unit operation
including verification of input and output ports, keypad and display.
Warranty
A standard one year warranty from date of manufacture is provided.
Miscellaneous Options
The MARCNX system offers full access capability of on-street controllers from an optional central office location via Windows-based PC software.
System components can communicate via hardwire, cable, optical fiber, or radio.
