Configuring the AirLink Device
Rev 2.3 Feb.12 21
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 a carriage return <CR> (ASCII
character 0x0D), i.e., 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
Note: AT commands work for the port on which they are executed. For example, if the
user types ATE1 and then AT&W using a USB/serial port connection, it will set the USB/
serial port to Echo On but not the telnet connection or the RS232 serial port.
Refer to Appendix E for a list of and details on AT Commands.
