PWMST provides the main control function, 128 channels
transmitting/receiving and related signal processing. It is also
connects to CWD board.
PMIO board receives MISC signals from PWMST board and
make necessary processing. And then, PMIO sends to Rear
Panel and KBDTRSF board.
KBDTRSF board receives MISC signals from PMIO board. It
males necessary processing and then sends to LCD monitor,
touch panel, main KBDboard, SoftKBD board and system
speakers.
APSTRSF is a power supply board in Vivid T8/ Vivid T8 Pro, it
accepts power from APS module and ACDC adapter. Under the
PWMST's control, it generates all kinds of voltages to meet the
power requirements of PWMST.
Power Control PWA is assembled in the power box. It provides
an interface for AC power input and provides isolated AC power
output for the system.
Relay board provides an interface for PWMST and four probes.
It transmit/receives signals from PWMST and provides an
interface for drive the LED board.
Rear Panel and BNC Board will receive MISC signals from
PMIO board and make necessary processing. It provides MISC
user interface.
