The following is an overview of the parameters contained in the COM Port Settings section:
Item
Port (COM0 for ALL
PORTS)
Baud Rate
Data Bits
Parity
Stop Bits
Rx FIFO Trigger Level
Data Buffered Delay
Time (DBDT)
End Char
Operation Mode
The COM Port number on the PDS-8x1 controller.
This parameter is used to set the Baud Rate for the COM
ports.
This parameter is used to set the Data Size for the COM
ports.
This parameter is used to set the Parity for the COM ports.
This parameter is used to set the Stop Bits for the COM
ports.
This option is used to set the number of characters that
the COM Port can receive at once time, the PDS-8x1
controller will move the data from the COM Port FIFO to
the PDS-8x1 controller. If the amount of data transferred
is large and uses a transfer speed (115200 bps), setting a
smaller value is helpful in preventing data loss.
When the COM port does not receive data from devices
connected over the period of DBDT setting, the PDS-8x1
controller will determine that the data transfer is over
and return to process next tasks.
The PDS-8x1 controller outputs an Ethernet packet
immediately after the ending-chars pattern is identified
from the incoming serial data.
M0: Transparent Mode (Multi-echo mode)
M1: Slave Mode (Single-echo mode)
M2: Half-Slave Mode (Is situated between M0 and the
M1 mode)
The more detailed information regarding M0, M1 and M2
modes, please refer to the
