3.5 MTPC BOARD
The function of the PC board is mainly the control of the Video hardware
via the software and to interface the peripheral equipment (i.e. remote
controller) with the Video hardware.
Three types of MTPC boards can be used:
• A1/R2 with JUKI 3712 motherboard (with Floppy Disk Drive)
• A2/A3 with COMMEL HS870 motherboard (with bootable USB)
• A2/A4 with COMMEL HS870 motherboard and a new time code
management module (with bootable USB)
In standard configuration the PC hardware is composed by:
• One mounting PC board, with serial ports, LTC reader and generator, is
controlled by the motherboard.
• IDE System Hard disk: the IDE disk drive is used for storing the EVS
software and the DOS operating system. Neither audio nor video data is
saved on this disk. The capacity of this drive may vary depending on
market availability, but the system partition is always set to 1GB. The
remaining capacity of this drive is not used.
• 64/128MB SDRAM modified. The SDRAM used has been modified to suit
the system requirements. Please contact EVS support for RAMs
upgrade. Do not use standard PC RAM modules.
