Assigning the IP using the serial port

After a Com-Server reset a time window of around 1-2 se-
conds is available on port A, during which you can assign a
new IP address, subnet mask and gateway address by ente-
ring at least 3 „x".
In contrast to other methods described above, this serial me-
thod functions regardless of whether the Com-Server already
has an IP address or not. The procedure can be repeated as
often as desired. The appendix contains the detailed procedu-
re under Windows.
Preparations/requirements
First connect the serial port A of the Com-Server to a com-
puter. For a standard PC or laptop, you will need a crossed
RS232 cable (=Null modem cable, see RS232 mode).
Any serial terminal program can be used for assigning. The
following transmission parameters must be set regardless of
any other settings in the Com-Server:
9600 baud, no parity, 8 data bits, 1 Stop bit, no Handshake
Start the serial configuration mode
Reset the Com-Server by interrupting the power. While the
Com-Server is starting up, use the terminal program to send
the letter x at least three times. The COM-Server will then re-
turn 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.
Together with the IP address, the subnet mask and gateway
address can also be assigned serially. The entry is separated
