# FM-SER is classified as DTE (Data Terminal Equipment) in terms of RS232 standard definition.
# RS485 half-duplex mode requires special HW/SW adaptation

'''RJ-11 Serial Ports'''<br>
The serial ports are arranged as COM ports differently on different motherboard configurations, as detailed in Table 2. The physical locations of the ports are depicted in Figure 1.

=== Configuration ===
'''Serial Ports Configuration'''
Each serial port can be individually configured to act in RS232 mode or RS485 half/full duplex mode. The configuration is selected in fit-PC3 BIOS setup.
The default selection between RS232 and RS485/RS422 is determined by E1 jumper position. Default mode determines the power-up state of the Dual Protocol Transceiver. It is applied to all ports and remains valid in case that software configuration is not performed.
The options of jumper E1 selections are detailed in Table 4.

After power-up, any individual port can be configured using software controlled SMBus system management protocol.
'''CAN Bus power supply'''
By default, the FM-SER consumes power from the CAN bus.
After power-up, the power supply option can be determined by a GPIO line connected to the motherboard, and is fully software controlled.
