INSYS WLAN serial 2.1 Function Overview
6Function Overview
The INSYS WLAN serial 2.1 offers the following functions :
WLAN to R232 interface transmission
The serial interface of the INSYS WLAN serial 2.1 can be reached from a
WLAN via a TCP- or UDP network connection . With the INSYS WLAN serial
2.1 you can integrate an application with serial interface into a WLAN.
Support of the WLAN Standards 802.11b/g with WEP and WPA
The INSYS WLAN serial 2.1 supports the WLAN standards 802.11 b/g. Fur-
thermore the INSYS WLAN serial 2.1 supports the encryption of data
transmission in the WLAN using the methods WPA-PSK and WEP . With the
WEP method, the INSYS WLAN serial 2.1 supports key lengths of 64 and
128 bit.
Configuration via HSComm or Terminal program
The most important functions of the INSYS WLAN serial 2.1 can be config-
ured with the help of the configuration software. Alternatively, the INSYS
WLAN serial 2.1 can be configured with a terminal program.
IP-configuration via DHCP
The INSYS WLAN serial 2.1 can receive its IP parameters (address, network
mask and gateway) from a DHCP server.
The IP-address can be assigned via ICMP and ARP
The IP address of the INSYS WLAN serial 2.1 can be assigned with the help
of the network tools arp and ping
Remote maintenance via Telnet
The INSYS WLAN serial 2.1 can be configured and serviced over the net-
work via Telnet. The access is password-protected.
Digital Switch Outputs and Inputs
The INSYS WLAN serial 2.1 has two switch outputs, which can be used to
switch other functions in an application. The INSYS WLAN serial 2.1 also
has digital inputs, the status of which can be read via AT command or via
configuration software HSComm.
IO tunnelling
The status of an input or output of the INSYS WLAN serial 2.1 can be
transmitted to other INSYS devices with IP tunnelling via a network con-
nection. This means that if the input at the INSYS WLAN serial 2.1 changes
its status, the status of the output of the device which is connected via IO
tunnelling is changed as well.
19

Function Overview INSYS WLAN serial 2.1
VCOM Support
Via INSYS VCOM, the virtual COM port, the INSYS WLAN serial 2.1 can
transmit serial data to an application, which does not support TCP/IP. This
means that older control center programs can also be connected to the IN-
SYS WLAN serial 2.1.
Firmware Update
The firmware of the INSYS WLAN serial 2.1 can be updated via terminal
program. An update can be performed locally or remotely.
