Architecture
• Writer Table 1: Host Display Subsystem Components Component
Description
Host CPU Board
The Host CPU located on an Advantech Computer on Module ROM-7420 Qseven has a main CPU in which the application software runs. The CPU interfaces with all peripherals through the Expansion board.
Expansion Board
All of the peripherals, such as the display, touchscreen, LAN, Wireless, USB ports, and KISS Pump are interfaced and controlled by the CPU through the Expansion board.
Display Touchscreen Assembly
The display is a 15.6–inch diagonal graphics LED backlit full HD display with P-CAP multipoint touch input, 1920 x 1080 resolution, and interfaced to the Expansion Board through the LVDS interface cable.
KISS Pump (optional)
A KISS pump is powered by the Expansion Board. The KISS pump power connector is terminated next to the Acquisition Module connector in the assembly.
Table 2: Writer Subsystem Components Component
Description
Printer Board
The Printer Board has a Programmable SoC (PSoC) that controls the system power-on, thermal printer interface, motor, and keyboard.
Power Supply
The power inlet connector interfaces with the AD/DC module. The AC/DC is a 150-Watt power supply accepting a wide input AC voltage range of 100 to 240 V at a frequency range of 50 to 60 Hz and delivering 24 DC to the printer board.
Keyboard
This device has a standard keyboard with alphanumeric keys, writer controls, and trimpad cursor controls. It also has LED indicators for battery status and AC mains status. The keyboard is available in different languages.
Thermal Printer
The printer has an A4/Letter thermal printhead, motor, paper sensors, and door sensor.
