NEMA TS-2 Type 2 - Secondary and Master Controllers

Model 980 - Secondary

NEMA TS-2 Type 2

The TS-2 Type 2 Model 980 Secondary and Model 981 Master / Secondary controllers are designed using state of the art electronics for reliability, long life, and superb performance in all signal control applications. The advanced architecture and NTCIP compliance provides the traffic engineer with a flexible platform for the future.

The Model 980 Secondary Controller meets and exceeds NEMA TS2 specifications, and includes advanced functionality for complex phasing, detector processing, coordination, preemption, communications, adaptive timing, as well as full systems operation in a closed-loop, hybrid, or centralized configuration.  

The advanced LCD display and menu driven software provides a user-friendly approach to programming and access, and built-in diagnostics permit rapid evaluation of operational status. The use of Flash Memory allows software upgrades without PROM replacement.

The basic difference between the Model 980 (Secondary) and the Model 981 (Master /Secondary) hardware is the additional serial port in the master unit.  The master unit also runs additional software allowing it to serve as a master and a secondary controller in a system configuration.

Model 981 - Master / Secondary

FEATURES

FLASH PROMS The Model 980 and 981 Controllers are easily configured to various firmware versions by the utilization of FLASH PROMS which eliminate the need for obsolete EPROM technology. A complete firmware update requires only ten minutes, and does not require hardware changes or EPROM replacements.
DISPLAY  A back-lighted 4-line by 40-character supertwist LCD display provides full menu screens for ease of data entry. The display maintains an optimum contrast and brightness over the entire NEMA specified temperature range, using special temperature-compensating circuitry. The menu-driven format and context sensitive help screens eliminate need for programming instructions or look-up codes.
EASILY SERVICED The Model 980 and 981 consist of only two printed circuit boards (three with optional modem) and an open frame power supply. The CPU/display board and the I/O board utilize machine tooled sockets for all integrated circuits for easy maintenance. An identification silkscreen on each circuit board clearly labels all components. No special tools or extender cards are needed for troubleshooting.
REAL-TIME CLOCK
The real-time clock maintains accurate timing by utilizing a “super capacitor” which allows accuracy of 0.005% during a 24-hour time period. Retention time during power failures for the real time clock is extendible to 30 consecutive days.
4 Rings / 16 Phases

/ 16 Overlaps

Naztec controllers allow the user to program a maximum of 16 phase sequences by assigning up to 16 phases in 4 separate rings (8 phases per ring). This flexibility combined with NTCIP concurrent phase definitions and 16 overlaps provides a phasing solution for single or multiple intersection control and diamond interchange operation.
KEYBOARD A 20-position keyboard containing 4 red function keys, 6 gray cursor movement keys, and 10 white digit keys with built in audio/tactile feedback provides user-friendly enhanced data entry.
DIAGNOSTICS Built-in diagnostics provide for improved maintenance and easier repairs. Internal diagnostics allow operator tests on all input and output signals, RAM devices, and memory. A built-in EEPROM eraser allows for a “clear-all” memory function.
COMMUNICATIONS Two RS-232 ports and an optional FSK modem port are available with each secondary unit.  Four RS-232 ports and an optional FSK port are available with each Master unit.  These ports are keyboard programmable with selectable baud rates from 300 to 19.2K with full and half duplex options. Various communication configurations allow the user multiple interfaces to other cabinet devices: conflict monitor, preemption equipment, detectors, WWV clocks, modems, notebooks, printers, etc. An RS-485 SDLC Bus Interface Port is provided for all TS2 Applications. The NTCIP protocol is fully supported.
