Product Overview
Hardware/Firmware Architecture
This system includes the following subsystems:
•
PWA main board
The main board has a main CPU in which the application software runs. All of the
peripherals, such as the display, internal modem, LAN, serial ports, USB ports, and
SD card are interfaced and controlled by this CPU. It also has a programmable SoC
that controls the power section, thermal printer interface, motor, and keypad. The
on-board DSP controls the integrated ACQ module.
•
Display
The display is a 7–inch TFT display with 800 x 480 resolution and interfaced to the
main board through the LVDS interface cable.
•
Keypad
This system has a matrix keypad with 10 x 9 interfaces, 66 normal keys, 16 stress
keys, and one dedicated power key. It also has LED indicators for battery status
and AC mains status.
•
Thermal printer
The printer has an A4/Letter thermal printhead, motor, paper sensors, and door
sensor.
•
Power supply
The power inlet connector is connected with the AD/DC module through an EMI
filter. The AC/DC is a 65W power supply accepting a wide input AC voltage and
delivering 24 DC to the main board.
•
KISS pump
An internal KISS pump is powered by the main board. The suction connector is
terminated next to the patient connector in the assembly.
Product Interfaces
This system offers the following interfaces for connecting to external devices for data
communication, software updates, and the control of workload devices:
• RS232 port (2)
• COMM Port A connects to the MUSE or CardioSoft system
• COMM Port B connects to a treadmill and other stress devices
• RJ45 port (1)
Connects to networks using a 100baseT Ethernet connector through an external
medical isolator.
• USB connector (2)
Connects to USB-capable devices, such as an optional barcode reader, external
USB keyboard, or WiFi Dongle.
• Secure Digital (SD) card slot
Interfaces with a Secure Digital card, which is used for the following:
• Storing ECGs
• Flashing the device with software updates
• Connecting memory or future I/O extensions
• RJ11 port (1)
Connects an internal medical grade analog modem (optional) to a phone line.
