Functions INSYS WLAN serial 2.1
11.13 Configuring IO Tunnelling
The INSYS WLAN serial 2.1 can transmit the states of the digital inputs and outputs
transparent to a remote terminal using the "IO tunnelling" function. You can use another
INSYS WLAN serial 2.1 or another INSYS device with IO tunnelling functionality as remote
terminal.
In order to transmit the states of the inputs to the outputs of another device, the address
of the respective remote terminal as well as its port must be configured at the involved
devices. The INSYS WLAN serial 2.1 transmits the input states to the remote terminal us-
ing UDP packets. It sends UDP packets every 30 seconds automatically or within 1 second
after a change at the inputs. The packets contain the status of the two alarm inputs UE
and UE2. The remote terminal evaluates the packets and sets their outputs UA and UA2
accordingly. This is an easy way to transmit two I/O lines from one device to another. The
transmission takes place "in the background" and is independent of the actual data con-
nection.
Configuration with HSComm
In order to configure IO tunnelling , configure on the "Network" tab in the
"Transfer IO status to partner device" panel the IP address and port of the re-
mote terminal (Figure 7, page 45, position 3)
In order to
enable or disable IO tunnelling , check or uncheck the checkbox
"on" (Figure 7, page 45, position 3).
Configuration with AT commands
In order to enable IP tunnelling , use the com-
mand
AT#IOT=1
In order to disable IP tunnelling , use the com-
mand
AT#IOT=0
In order to configure the IP address and port of
the remote terminal , use the command
Enter instead of <IP> the IP address and in-
stead of <Port> the port number of the remote
terminal.
AT&Z1=<IP>:<Port>
