Configuring the UDS Using Telnet or the Serial Port

Manual Connection
The UDS attempts to connect when directed by a command string received from the
serial port. The first character of the command string must be a
C
(ASCII 0x43), and
the last character must be either a carriage return (ASCII 0x0D) or a line feed (0x0A).
No blanks or space characters may be in the command string. Between the first and
last command string characters must be a full or partial destination IP address and
may include a destination port number.
The IP address must be in standard dot-decimal notation and may be a partial
address, representing the least significant 1, 2, or 3 bytes of the remote IP address. A
period is required between each pair of IP address numbers.
If present, the port number must follow the IP address, be a decimal number in the
range 1-65535, and be preceded by a forward slash (ASCII 0x2F). The slash
separates the IP address and the port number. If you omit the port number from a
command string, the internally stored remote port number starts a connection.
If a command string contains a partial IP address, the UDS interprets the command
string as the least significant bytes of the IP address and uses the internally stored
remote IP address to provide the most significant bytes of the IP address.
If the IP address entered is 0.0.0.0/0, the device server enters Monitor Mode.
For example, if the remote IP address already configured in the unit is 129.1.2.3, then
an example command string would be C3/7. (This would connect to 129.1.2.3 and
port 7.) You may also use a different ending for the connection string. For example,
C50.1/23 would connect you to 129.1.50.1 and port 23.

Connect to 129.1.28.10, port 12
Autostart (Automatic Connection):
If you enable autostart, the unit automatically
connects to the remote IP address and remote port specified.
Datagram Type:
When you select this option, the unit prompts for the datagram
type. Enter
01
for directed or broadcast UDP.
Hostlist:
If you enable this option,
the Lantronix unit scrolls through the hostlist until it
connects to a device listed in the hostlist table. Once it connects, the unit stops trying
to connect to any others. If this connection fails, the unit continues to scroll through
the table until it connects to another IP in the hostlist. Only Channel 1 supports the
hostlist option.
