(3). FPIO2: IR Header (Infrared)

There is a specific orientation for pins 1 through 5, attach the connector from the IR KIT or IR device to the FPIO2 header. This motherboard supports standard IR transfer rates.

Note: Watch the pin position and the orientation

(4). SMB1 and SMB2 System Management Bus (SM-Bus) Connectors

These two connectors are reserved for the system management bus (SM-Bus). The SM-Bus is a specific implementation of an I2C bus. I2C is a multi-master bus, this means that multiple chips can be connected to the same bus and each one can act as a master by initiating a data transfer. If more than one

master simultaneously tries to control the bus, an arbitration procedure decides which master gets priority. You can connect the devices that utilize the

SM-Bus.

Note: Watch the pin position and the orientation

(5). RT1: System Temperature Thermistor

The RT1 is used to detect the system environment temperature. You can see the readings in the BIOS or the hardware monitoring software screen.
