3.4 Assigning the IP using the serial port
After a device reset a time window of around 1-2 seconds is
available, during which you can assign a new IP address, sub-
net mask and gateway address by entering at least 3 „x“.
In contrast to other methods described above, this serial
method functions regardless of whether the device already
has an IP address, a password or not. The procedure can be
repeated as often as desired.
1 To avoid unintended changes to the IP address, the
DHCP client of the device is automatically deactivated
when configuring using the serial port.
Preparations/requirements
First connect the serial port A of the device to a computer. For
a standard PC or laptop, you will need a crossed RS232 cable
where only the pins 2,3, and 5 are connected.
Any serial terminal program can be used for assigning. The
following transmission parameters must be set regardless of
any other settings in the device:
9600 baud, no parity, 8 data bits, 1 Stop bit, no Handshake
Start the serial configuration mode
Reset the device by interrupting the power. While the device
is starting up, use the terminal program to send the letter x
at least three times. The device will then return the prompt
IPno.+<Enter>:.
Assigning the IP settings
Use the usual format (xxx.xxx.xxx.xxx) to enter the IP
address, and end the entry by pressing <Enter>. If the ent-
ry was accepted, the acknowledgement is the assigned IP
address. Otherwise you will get a FAIL message followed by
the last current IP address.
