Configuring your AirLink device

Rev 2.0 C Aug.10 17

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 port.

Data Communication

• Public and Private Modes: The method used by the AirLink device to pass

an IP address to a connected device.

•Keepalive: How the AirLink device maintains its connection to the cellular

network.

AT Mode

Using a terminal connection, AT commands can be used to configure the device,

command it to do something, or query a setting. ACEmanager is a graphical user

interface for most AT Commands and includes other parameters without AT

counterparts..

• AT commands must always be terminated by <CR> (ASCII character 0x0D),

a carriage return (pressing enter on the keyboard). Some may also include a

new line or line feed <LF>.

• If E=1 (Echo On), the AT command (including the terminating <carriage

return) will be displayed (output) before any responses.

• Two settings affect the format of AT command output: V (Verbose) and Q

(Quiet).

• If Q=1 (Quiet On), no result codes are output whatsoever, so there is no

response generated by a (non query) command.

• If Q=0 (Quiet Off), result codes are output. The format of this output is then

affected by the Verbose setting.

If Quiet mode is off, the result code is affected as follows:

For V=1 (Verbose mode), the textual result code is surrounded by a

carriage return and new line. Any AT query response is also surrounded

by a carriage return and new line.

For V=0 (Terse mode), a numeric result code is output with a single

trailing carriage return (no new line is output), while any AT query

response is followed by a carriage return and new line (there is no

preceding output).

• For example, possible output to the AT command “AT” with carriage return

(assuming quiet mode is not on) is:

carriage return - if V=0

carriage return and new line OK another carriage return and new line - if

V=1
