Serial Port Profiles

144 

IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0

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.

The direction in which information is received or relayed:

z

Disabled—UDP service not enabled.

z

 can be set to 

 or 

. The IOLAN 

will listen on port value configured in the 

 parameter for messages coming from the learned or configured port.

z

 can be set to 

 only. The IOLAN will listen 

on the port value configured in the 

 

parameter and will send to the configured port.

z

Both—Messages are relayed in both directions. UDP Port can be set to 

 or 

. For messages coming from the LAN to the serial 

device, IOLAN will listen on port value configured in the 

 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 

 parameter and will send to the configured 

or learned (if 

 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

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

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

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 

 is set to 

or 

.

z

Any Port—The IOLAN will receive messages from any port sending UDP 
packets. Applicable when 

 is set to 

.

z

Port—The port that the IOLAN will use to relay messages to 
servers/hosts. This option works with any 

 except 

. The 

IOLAN will listen for UDP packets on the port configured by the 

 parameter.

Default: Auto Learn

The port that the IOLAN will use to relay messages to servers/hosts. This 
option works with any 

 except 

. The IOLAN will listen for 

UDP packets on the port configured by the 

 parameter. 

Default: 0 (zero)
