Data Communication and Host Modes
Rev 3.0B Feb.08 51
• UDP and UDP PAD: Any data received on the serial port
is assembled into UDP packets and sent to the session’s
associated IP address and Port (described later). Any
responses received from the associated IP address and port
destined for the Device Port are unwrapped and sent out
the serial port.
• TCP and TCP PAD: Any data received on the serial port is
packaged into TCP messages and sent to the associated
connection’s IP address and Port (described later). Any
data received from the TCP peer is unwrapped and sent
out the serial.
Data Communication
• Public and Private Modes: The method used by the Raven
to pass an IP address to a connected device.
• Keepalive: How the Raven maintains its connection to the
cellular network.
Basic Modes
Start up Mode
The serial port of the Raven can be configured to enter any of
the modes automatically on power up (in most cases, this is
also after it has registered on the cellular network). This is
done by setting the Startup Mode Default to the desired mode.
If this setting is non‐zero, the modem will enter the specified
mode after 5 seconds. If you want to cancel this behavior, the
ATMD0 command can be used before the 5‐second time‐out
expires.
You can configure the Startup Mode in AceManager at part of
the UDP group.
