Baud rate
Select the serial transmission speed from “300” to “115200” Baud (bits per second).
Data bits
Select “7” or “8” data bits.
Parity
Select “no”, “even” or “odd” parity.
Stop bits
Select “1” or “2” stop bits.
Flow control
Select the type of flow control: “none”, “Software (XON/XOFF)” or “Hardware (RTS/CTS)”.
Local port
Defines the port on which the serial port can be accessed for serial gateway application. Only
when “Local port” is set to "0" the serial port can be used as a command interface.
If the active serial gateway is enabled and the "Local port" is set to a value then this will be the
source port of the TCP connection. On "0" a random source port is used.
Destination IP
To have this device actively establish a serial gateway select the destination IP address to the
device where the serial data will be transmitted to (and received from).
Select "0.0.0.0" when the serial port is used only locally.
Destination port
Defines the port for the active serial gateway function (see destination IP).
Notes: Both settings, "Destination IP" and "Destination port" have to be set to enable the gateway
function. When the Serial Gateway is activated the serial port cannot be used as a command
interface. This also applies for the device on the other side of the "Serial Gateway".
To establish a "Serial Gateway" between two devices only one device has to be activated. In other
words: Only one device will need a Gateway destination IP and Port set. The other side only needs
the parameter “Local port” to be set to the same value as the above “Destination port”. On power
up the active device connects to the selected device and tries to reconnect automatically if the
connection is lost. This allows the establishment of a serial connection between the attached
devices on each side, over a LAN or WAN.
