Meaning
This item allows you to enable or disable high performance event timer (HPET) support.
This item allows you to select the unit's response when power is re-applied to the unit after a power loss (for
example, an unplugged power cable).
By selecting S5, the unit will stay powered off when power is re-applied after a power failure.
By selecting S0, the unit will power on when power is re-applied after a power failure.
This item allows you to enable or disable a COM port.
This item allows you to specify whether COM port 1 should be used as an RS-232 or RS-485 port.
This item is only visible when FPGA COM1 is set to Enabled.
❖
This item allows you to specify the amount of memory reserved to be mapped to the memory's input-output
range (MMIO).
This item should not be changed.
❖
This item allows you to enable or disable the FPGA Auxiliary I/O.
This item allows you to enable Power Over Ethernet (PoE) for all Ethernet ports that support it.
The following precautions should be taken whenever using PoE ports or peripherals:
• Make sure that your Matrox 4Sight GPm unit is turned off prior to connecting or disconnecting any PoE
peripherals, such as a camera.
• Enable Power over Ethernet (PoE) only on the ports that require it. If a peripheral does not require power
from the Ethernet cable, keep PoE disabled on that board through the BIOS.
