IntelliBox-I/O 2100 User Guide 168
Connect Mode has six variations:
 Disabled (no connection)
 Enabled (always makes a connection)
 Active if it sees any character from the serial port (makes a connection upon
receiving any character)
 Active if it sees a specific (configurable) character from the serial port
 Modem emulation (controlled by modem commands)
 Modem control asserted (makes a connection when the modem central signal on the
serial line becomes active)
For the “any character” or “specific character” connection states, the IntelliBox 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 IntelliBox 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, and 10002 for serial port 2.
Accept Mode supports the following protocols:
 SSH (IntelliBox 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
Accept Mode has the following options:
 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 (when the modem control on the serial line corresponding to
the tunnel becomes active)
