Communication Circuitry
The Ethernet communication section of the main processor PCB provides
an Ethernet communication interface for the monitor. The data is sent
and received at a rate of 10M bits per second over the Ethernet-based
Unity Network.
The communication circuitry also provides for Tram-net
communications. (Tram-net signals are not provided for the SolarView
remote display controller.) The Tram-net controller packages the data for
serial transmission to/from the monitor peripherals and relieves the
main microprocessor from performing the serial transmission conversion.
The data transferred may be patient data from the Tram-rac housing or
user input signals from a remote control. An FPGA functions as a header
hub in the Tram-net local-area network returning the sent data to all
nodes.
Asynchronous signals are sent to/from the four UART devices on the
main processor PCB. Async data is processed for serial transmission to
the auxiliary async (RS232/RS422) ports. The RS422 async port is used
for the peripheral devices like the DDW, remote control, and for software
updates. The RS232 port is reserved for future use.
Low-Voltage Power
Supply
The low-voltage power supply converts the AC voltage from the
transformer windings to provide all low voltage power requirements for
the monitor as fi16.75V and +5V.
For the Solar 7000 monitors, +24V DC is also provided. Only when a
control line from the main processor PCB is activated to the color Solar
7000 low-voltage power supply, the power supply will connect 100V to the
degaussing coil for the CRT.
Keycap PCB
The keycap PCB interfaces with the user and the main processor PCB. It
receives user input from the five hard keys and the Trim Knob control.
Additional Solar 7000
Circuit Boards
The following circuit boards are used in the Solar 7000 monitor only.
Mono CRT Controller
PCB
The monochrome CRT controller PCB controls electron beam deflections
in both axes and contains all the necessary drive circuitry for the display.
It contains circuitry for horizontal deflection, vertical deflection, video
drive, and dynamic focus. A protection circuit is provided to shut off the
electron beam should one of the deflection signals be lost.
Color CRT Controller PCB
The CRT controller PCB receives video and sync data from the main
processor pcb assembly. The video signals are amplified and DC level
restored. This pcb drives the three cathodes that control the intensity of
the color CRT.
Deflection PCB (Color
Only)
The deflection PCB provides the deflection signals to the yoke for
synchronous scanning of the CRT. The synchronizing signals are received
from the main processor PCB. This circuit board also develops auxiliary
voltages for other assemblies in the monitor.
