Clock Rate
This is the “Data Rate" value for on board crystal frequency of input clock. The
baud rate can optionally be adjusted according to the data rate required. The
clock pre-divisor is used to divide the input clock prior to baud rate generation.
This parameter must matches with the oscillator (crystal) frequency on the board.
System default is 14745600 Hz. We do NOT recommend for modification
without SUNIX instruction. User can click “Defaults” button back to manufactory
settings.
UART Type (Default: Auto RS-422/485 )
User can select RS-422 or RS-485 interface for each COM port of this board.
1). Auto RS-422/485
SUNIX developed a unique technology “Auto Detect & Switching RS-422/485,
which can automatically detect the state of RS-422 full duplex or RS-485 half
duplex and control the data transmitting and receiving wires at the same port
without any hardware or software settings.
2). RS-422 (4-Wire RS-485)
This COM port forces to run RS-422 full duplex mode.
(RS-485 ACS function can not open under this mode.)
3). RS-485
This COM port forces to run RS-485 half duplex mode.
