Type
List box {possible values}, default = "RS232"
COM port can be configured to either RS232 or RS485.
Baud rate [b/s]
List box {standard series of rates from 600 to 1152000 b/s}, default = "19200"
Select Baud rate from the list box: 600 to 1152000 b/s rates are available.
Serial ports use two-level (binary) signaling, so the data rate in bits per second is equal to the
symbol rate in bauds.
Data bits
List box {8; 7}, default = "8"
The number of data bits in each character.
Parity
List box: {None; Odd; Even}, default = "None"
Wikipedia: Parity is a method of detecting errors in transmission. When parity is used with a serial
port, an extra data bit is sent with each data character, arranged so that the number of 1-bits in
each character, including the parity bit, is always odd or always even. If a byte is received with the
wrong number of 1-bits, then it must have been corrupted. However, an even number of errors can
pass the parity check.
Stop bits
List box {possible values}, default = 1
Wikipedia: Stop bits send at the end of every character allow the receiving signal hardware to detect
the end of a character and to resynchronize with the character stream.
Idle [ms]
Number {10 – 16383}, default = 20
This parameter defines the maximum gap (in milliseconds) in the received data stream. If the gap
exceeds the value set, the link is considered idle, the received frame is closed and forwarded to
the network.
MRU [B]
Number {1 – 2047}, default = 1500
