OnCell G3100 Series Additional Serial Port Settings
Port Communication Parameters
Port alias: This optional field allows you to assign an alias to a port for easier identification.
Serial Parameters
ATTENTION
The serial parameters for the ea
ch serial port on the OnCell G3100 should match the parameters u
serial device. You may need to refer to your serial device’s user’s manual to determine the
serial communication parameters.
Baudrate (default=115200 bps): This field configures the port’s baudrate. Select one of the standard
baudrates from the dropdown box, or select Other and then type the desired baudrate in the input box.
the port requires a special baudrate that is not listed, such as 500000 bps, you may can select the
and enter the desired baudrate into the text box. The OnCell G3100 will automatically calculate the
supported baudrate. The margin for error will be less than 1.7% for all baudrates under 921600
Data bits (default=8): This field configures the data bits parameter. Note: If data bits is set to 5 bits, stop bits
will automatically be set to 2 bits.
Stop bits (default=1): This field configures the stop bits parameter. Note: If data bits is set to 5 bits, stop bits
will automatically be set to 1.5 bits.
Parity (default=None): This field configures the parity parameter.
Flow control (default=RTS/CTS): This field configures the flow control type.
FIFO (default=Enable): This field enables or disables the 128-byte FIFO buffer. The OnCell G3100 provides
FIFO buffers for each serial port, for both the Tx and Rx signals. Note, however, that you should disable the
port’s FIFO setting if the attached serial device does not have a FIFO buffer of its own. This is because a serial
device that does not have its own buffer may not be able to keep up with data sent from the OnCell’s FIFO
buffer.
Interface (default=RS-232): You may configure the serial interface to RS-232, RS-422, RS-485 2-wire, or
RS-485 4-wire.
