The IP Address Filter parameter allows you filter out packets
received by the Serial Adapter from any IP Address other than
one specified IP Address. You may specify only one IP Ad-
dress from which to accept messages. The default for this
parameter is to receive packets from any IP Address.
The configuration menu allows you to apply Packet Type
Filters to limit the type of messages the unit receives. You may
chose to filter either Point-to-Point or Broadcast messages. By
default, the Serial Adapter will accept all packet types.
The Escape Parameters option allows you to customize when
the configuration menu will appear by changing the Escape-to-
Menu Character from “$” and by changing the Escape-to-
Menu Delay settings to an interval of 0.1 of a second. Note that
when entering a value for the Escape-to-Menu parameter, a value
of 1 corresponds to a delay of 0.1 second. Likewise, a value 10
corresponds to a 1 second delay.
The Escape-to-Menu Delay parameter sets the length of time
which must elapse, with no additional keystrokes, both before
and after the three identical Escape-to-Menu Characters are sent
to the Serial Adapter. By default, the configuration menu
appears when “$$$” is sent to the Serial Adapter and the unit has
not received any characters for 1 second before or after the
receipt of “$$$”.
The Notify Remote Nodes of Pin Status Change parameter is
only relevant when the Serial Adapter is in Packetized mode.
When enabled, the Serial Adapter will pass changes in the status
of the RTS, CTS, DTR, DSR, RI, and CD pins to the remote side
of the connection. This information is not visible to the user.
The Lost Communication parameter allows you to set the
behavior of the Serial Adapter when it is in Pass-through mode
