Command Overview INSYS WLAN serial

Command Description

AT&K

Data flow control

AT&K

sets the function of the data flow control.

AT&K0

switches the data flow control off (default).

AT&K3

switches the hardware data flow control (RTS/CTS) on

AT&K8

Activates the controlled half duplex operation on the serial interface for
RS485

In this mode, the CTS signal is deactivated (high), while the device sends data
at the serial interface. Thus, the CTS signal can be used as driver release
signal for a RS485 driver. Controlling of the data direction for RS485 takes
place via the CTS signal. Polarity setting via

AT&R

.

AT#KEEP

TCP/IP Keep Alive

This timer enables the monitoring of an existing TCP/IP connection when no data is
transferred. When 3 consecutive monitoring packets are not answered, the connection is
terminated and re-established, if necessary (in leased line mode, see

AT&L

).

AT#KEEP=n

n=1..255

The time between monitoring packets in units of 10 seconds

n=0

No monitoring packets (default)

The setting

AT#KEEP

is immediately stored in the permanent memory (independent

from the command

AT&W

).

AT#KEYn

=

Define WEP keys

Entering of the WEP keys 0..3 as a series of hexadecimal digits (0..9,A..F) in quotes. After
every two digits an underscore follows as separator.

For 64 bit keys 10 hexadecimal digits are required; for 128 bit keys 26 hexadecimal digits.

Default setting: empty keys (all 0)

AT#KEY0

=”11_12_13_14_15_16_17_18_19_1a_1b_1c_1d”

AT#KEY1

=”11_12_13_14_15_16_17_18_19_1a_1b_1c_1d”

AT#KEY2

=”11_12_13_14_15_16_17_18_19_1a_1b_1c_1d”

AT#KEY3

=”11_12_13_14_15_16_17_18_19_1a_1b_1c_1d”

A single WLAN is determined by joint codes (SSID) and WEP keys.

WEP encryption is switched on via

AT#WEL

. The key length is determined via

AT#WKL

. The

active WEP key is selected with

AT#WKY

.

The setting

AT#KEYn

is immediately stored in the permanent memory (independent

from the command

AT&W

). The setting will only take effect with Reboot (

AT#RBT

).

AT#NM

Set network mask

AT#NM

sets the address range of the local network in connection with

AT#IP

. All packets

that are not sent to the local network, are sent to the gateway address set by

AT#GW

.

The default setting is

AT#NM

=255.255.255.0

The setting

AT#NM

is immediately stored in the permanent memory (independent from

the command

AT&W

). The setting will only take effect with Reboot (

AT#RBT

).

IP address, gateway and network mask must be coordinated in the local network
segment.

AT&O

Set the function of the OH line

AT&O0

OH is active (low) as soon as a physically functioning WLAN link is available,
i.e. the module is registered at the AccessPoint. (Link ok, default)

AT&O1

OH is active (low), as soon as a connection (TCP/IP or UDP/IP) is active
