NEMA TS-2
Type 2
Secondary and Master Controllers
|
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 maser
unit. The master unit also runs additional software allowing it to serve as a master and a
secondary controller in a system configuration. |
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. |
