Gateway Configuration
Default is Ethernet format.
Ethernet address This is the 12-digit MAC address of the controller’s Ethernet adapter.
The address is assigned by the System Manager and administered
locally.
Enter the last 8 hexadecimal characters of Ethernet address. The
first 4 positions of the address are 0200 ( Ethernet format ) or 4000
( Token-Ring format ).
Valid characters are 0-9, and A-F (upper case).
SAP Enter the Service Access Point (SAP) for the Controller. The value is
in hexadecimal ranging from x'04' to X ‘FC', in multiples of 04. For
example, valid values could be x'04', x'08', x'0C', x'10', and so on.
Valid characters are 0-9 and A-F (upper case).
NOTE: Each Ethernet adapter has a unique MAC address. Since
each Ethernet adapter is capable of supporting several PU’s and a
Gateway, they must be differentiated by using the SAP address.
Use other addresses than the defined SAP addresses which are
displayed on the screen.
Response Timer This value is the maximum time allotted to receive an appropriate
response from the workstation. The minimum value must be the total
number of possible frame delays in a system. Valid values are 1-20
seconds. Default is 1.
Inactive Timer This value is the maximum time that the Token-Ring/Ethernet
network or workstations may be inactive before it is considered
inoperative. The minimum value must be ten times the Response
Timer value.
Valid values are 1-99 seconds. Default is 30.
Receiver
Acknowledgment
Timer This value is the maximum time that the controller is allowed to send
acknowledgments to the attached workstation.
Valid values are 1-255 milliseconds. Default is 30.
Retry counter This value is the maximum number of retries to perform the
checkpoint procedure, including retransmission after the Response
Timer has expired. The combination of the Response Timer value
and the Retry Counter must allow for error detection and recovery on
the network. Valid values are 1-99 retries. Default is 8.
Maximum Out This value is the maximum number of frames sent by the controller
before waiting for an acknowledgment. The minimum value must be
4
