3202D Sign Driver
The 3202D sign driver is microprocessor based. It provides a link between the NTCIP Sign Controller and the row and column drivers that operate the disk elements of the sign. It accepts serial communication from the NTCIP Sign Controller, and on command displays messages and returns status information. Power is supplied locally by an on board low differential regulator.

AutoBoot©
AutoBoot© is an intelligent, automatic, equipment re-booting device. AutoBoot© counts the number of rings when connected to a standard telephone line. After six unanswered rings, a general purpose output on the device cycles power (10 seconds OFF) to connected equipment
including modems, power supplies and controller equipment.

Column Driver Board
The Column board interfaces the 3202 sign driver PWB to the 5 X 7 disk modules that make up the sign. The 3202 sign driver uses only low voltage, low current logic levels. The driver board decodes and converts these logic levels to the 3 amp, 30 to 40 volt drive level required for the electromagnetic coils on the display modules.

Lighting Control Master Module/Photocell Module (LCMM/PM)
The Lighting Control Master Module/Photocell Module (LCMM/PM) is a microprocessor-based module designed to control up to 63 Light Control Slave Modules (LCSM). The LCMM/PM can precisely control the brightness of 2 or 4 lamps connected to each LCSM as well as determine the status of the lamps connected to the LCSM’s.

General Purpose I/O PWB
The General Purpose I/O Card (GPIO) is a multi-purpose circuit board that is part of the 3800 series of sign controllers. It supplies the controller with input/output (I/O) signals at transistor-transistor levels (TTL) and it also regulates power to the controller from the Model 1 power supply.

3800 Keypad Assembly
The 3800 Keypad assembly is an integral part of the 3800 series controller. This assembly accomplishes many functions including providing an interface between the user/control system and the 3800 controller. The Keypad is powered by the Model 1 Power Supply via the STD Bus Card Cage and controlled by the parallel output port of the WinSystems CPU.

Lighting Control Master Module (LCMM)
The Lighting Control Master Module (LCMM) is a microprocessor-based module designed to control up to 63 Light Control Slave Modules (LCSM). The LCMM can precisely control the brightness of 2 or 4 lamps connected to each LCSM as well as determine the status of the lamps connected to the LCSM’s.

Lighting Control Photocell Module (LCPM)
The Lighting Control Photocell Module (LCPM) is a microprocessor-based module designed to read the brightness levels of up to three photocells and transfer the data to the Lamp Control Master Module (LCMM). The LCPM also has 2 temperature inputs and contains output control for fans, heaters, abort relays and general-purpose outputs.

Lighting Control Slave Module (LCSM)
The Lighting Control Slave Module (LCSM) is a halogen lamp level controller designed to work in conjunction with the Lamp Control Master Module (LCMM). The LCSM will drive either 2 or 4 - 12 Volt, 50 W halogen lamps and will provide lamp status information back to the LCMM. The LCSM provides up to 32 levels of brightness using zero crossing, phase controlled dimming circuits.

Model 1 Power Supply
The Model 1 Power Supply is a robust switching-type power supply, designed to provide a reliable source of uninterrupted power. Features include transformer line isolation, ELV (extra low voltage) operation, UPS battery back-up with zero transfer time, an integral charger, a low voltage alarm, and load dump circuitry.

Reflective Disk Display Module
These module assemblies consists of 35 reflective disk elements arranged in a 5 X 7 matrix. Each element can be individually programmed to be set (reflective color side out) or reset (non-reflective side out). The sign module assembly can be one individual module or can be grouped with other modules to form a unique display pattern.

netDMS© Sign Controller
The netDMS© Sign Controller is a microprocessor-based device for controlling and monitoring overhead and portable traffic information signs and general-purpose text-only signs. Fiber-optic enhanced reflective disk, reflective disk and LED type Dynamic Message Signs (DMS) are supported as well as Blank Out Signs, Changeable Message Signs, Lane Control ...

Row Driver Board
The row driver board interfaces the 3202 sign driver PWB to the 5 X 7 disk modules that make up the sign. The 3202 sign driver uses only low voltage, low current logic levels. The row driver board decodes and converts these logic levels to the 3 amp, 30 to 40 volt drive level required for the electromagnetic coils on the display modules. The row driver board incorporates failsafe circuitry to prevent coil burn-out in case of 3202 failure. On board sensing circuitry allows the 3202 driver to determine if a coil on a display module is open, shorted, or normal.

RS323 Interface Board
The RS232 PWB provides RS232 to TTL level conversion, power supply, and switch input (option selection) for the 3202 D/G sign driver PWB assembly. It has its own 5V power supply for local operations (a requirement for compatibility with older drivers) and develops the +/- voltage supplies for RS232 level conversion locally.
