EDS4100 4 Port Device Server User Guide 124
Connect Mode has five states:
 Disabled (no connection)
 Enabled (always makes a connection)
 Active if it sees any character from the serial port
 Active if it sees a specific (configurable) character from the serial port
 Modem emulation
For the “any character” or “specific character” connection states, the EDS4100 waits and
retries the connection if the connection cannot be made. Once it makes a connection and
then disconnects, it does not reconnect until it sees any character or the start character
again (depending on the configured setting).
Accept Mode
In Accept mode, the EDS4100 waits for a connection. The configurable local port is the
port the remote device connects to for this connection. There is no remote port or
address. The default local port is:
 10001 for serial port 1
 10002 for serial port 2
 10003 for serial port 3
 10004 for serial port 4
Accept Mode supports the following protocols:
 SSH (EDS4100 is the server in Accept Mode). For this protocol, the SSH server host
keys and at least one SSH authorized user must be configured.
 TCP
 AES encryption over TCP
 Telnet/IAC mode (The EDS4100 currently supports IAC commands, but these
commands are not passed to the serial devices attached to the EDS4100.)
Accept Mode has the following states:
 Disabled (close the connection)
 Enabled (always listening for a connection)
 Active if it receives any character from the serial port
 Active if it receives a specific (configurable) character from the serial port (same start
character as Connect Mode’s start character)
 Modem control signal
