Serial Port Profiles
144 IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0
Terminal Profile
Overview
The Terminal profile allows network access from a terminal connected to the IOLAN’s serial port.
This profile is used to access pre-defined hosts on the network from the terminal.
Direction The direction in which information is received or relayed:
z Disabled—UDP service not enabled.
z LAN to Serial—UDP Port can be set to Auto Learn or Port. The IOLAN
will listen on port value configured in the
Listen for connections on UDP
port
parameter for messages coming from the learned or configured port.
z Serial to LAN—UDP Port can be set to Port only. The IOLAN will listen
on the port value configured in the
Listen for connections on UDP port
parameter and will send to the configured port.
z Both—Messages are relayed in both directions. UDP Port can be set to
Auto Learn or Port. For messages coming from the LAN to the serial
device, IOLAN will listen on port value configured in the
Listen for
connections on UDP port parameter for messages coming from the
learned or configured port. For messages going from the serial device to
the LAN, the IOLAN will listen on the port value configured in the
Listen
for connections on UDP port parameter and will send to the configured
or learned (if
Auto Learn is enabled, the IOLAN must receive a UDP
message before it can send one, since the port must first be ’learned’) port.
Default: Both for UDP 1 and Disabled for all other UDP ranges
Start IP Address The first host IP address in the range of IP addresses (for IPv4 or IPv6) that the
IOLAN will listen for messages from and/or send messages to.
Field Format: IPv4 or IPv6 address
End IP Address The last host IP address in the range of IP addresses (for IPv4, not supported
for IPv6) that the IOLAN will listen for messages from and/or send messages
to.
Field Format: IPv4 address
UDP Port Determines how the IOLAN’s UDP port that will send/receive UDP messages
is defined:
z Auto Learn—The IOLAN will only listen to the first port that it receives a
UDP packet from. Applicable when
Direction is set to LAN to Serial or
Both.
z Any Port—The IOLAN will receive messages from any port sending UDP
packets. Applicable when
Direction is set to LAN to Serial.
z Port—The port that the IOLAN will use to relay messages to
servers/hosts. This option works with any
Direction except Disabled. The
IOLAN will listen for UDP packets on the port configured by the Listen
for connections on UDP port parameter.
Default: Auto Learn
Port The port that the IOLAN will use to relay messages to servers/hosts. This
option works with any Direction except Disabled. The IOLAN will listen for
UDP packets on the port configured by the
Listen for connections on UDP
port
parameter.
Default: 0 (zero)
