Connect Mode
In Connect Mode, theEDS-MD4/8/16 continues to attempt an outgoing connection on the network,
until established. If the connection attempt fails or the connection drops, then it retries after a
timeout. The remote node on the network must listen for the Connect Mode’s connection.
For Connect Mode to function, it must be enabled, have a remote station (node) configured, and a
remote port configured (TCP or UDP). When established, Connect Mode is always on. Enter the
remote station as an IP address or DNS name. TheEDS-MD4/8/16 will not make a connection
unless it can resolve the address.
For Connect Mode using UDP, theEDS-MD4/8/16 accepts packets from any device on the
network. It will send packets to the last device that sent it packets.
Note:
The Port in Connect Mode is not the same port configured in Accept Mode.
The TCP keepalive time is the time in which probes are periodically sent to the other end of the
connection. This ensures the other side is still connected.

Settings
Description
Mode
Set the method to be used to attempt a connection to a remote host or
device. Choices are:
Disable
= an outgoing connection is never attempted. (
default
)
Always
= a connection is attempted until one is made. If the connection
gets disconnected, the EDS-MD retries until it makes a connection.
Any Character
= a connection is attempted when any character is read
on the serial line.
Start Character
= a connection is attempted when the start character for
the selected tunnel is read on the serial line.
Modem Control Asserted
= a connection is attempted as long as the
Modem Control pin (DSR) is asserted, until a connection is made.
Modem Emulation
= a connection is attempted when triggered by
modem emulation AT commands.
Local Port
Enter an alternative Local Port. The Local Port is set to <Random> by
default but can be overridden. Blank the field to restore the default.
Host 1
Click on the displayed information to expand it for editing. If <None> is
displayed, clicking it will allow you to configure a new host. At least one Host
is required to enable Connect Mode as this information is necessary to
connect to that host.
Reconnect Timer
Set the value of the reconnect timeout (in milliseconds) for outgoing
connections established by the device. Valid range is 1 to 65535
milliseconds. Default is 15000.
Flush Serial Data
Set whether the serial Line data buffer is flushed upon a new network
connection. Choices are:
Enabled
= serial data buffer is flushed on network connection
Disabled
= serial data buffer is not flushed on network connection
