The COM Port number on the PDS-220Fx.
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-220Fx will move the data
from the COM Port FIFO to the PDS-220Fx. 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-220Fx will determine that
the data transfer is over and return to process next tasks.
Set the receive buffer size. When the buffer receives the data
reaches to value, it will be sent out.
Settings range: 1 ~ 1460 Bytes
The PDS-220Fx 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)
M3: Modbus Gateway
The more detailed information regarding M0, M1, M2 and M3
modes, please refer to the Section 4.3.1 "Operation Mode: M0, M1,
M2 and M3".
