19.  Enter  the  obtained  number  into  the  IP  address  boxes.  You  should  be  safe  using

192.168.0.1 for the gateway address and 255.255.255.0 for the Submask.

20.  Download  the  new  data  to  Netiom-UDP  using  the  “Write  To  NETIOM”  button  on  the

general page.

21 When the download is complete remove the programming link.

Interface Software

PC based software is provided to provide a graphical interface to programming Netiom-UDP.

On  the  opening  page  there  are  controls  for  loading  and  sending  data  and  a  logging  area

which will show a log of activity as well as any problems encountered.

The Data page is used to set all the necessary parameters for the Netiom-UDP.

Data

Data can be written to Netiom-UDP or read from it via the serial port at 19200 baud. Note that

the  programming  link  must  be  in  place  before  communications  can  be  established  with

Netiom-UDP. The best way to use the program is to read data from Netiom-UDP, modify it

and then write it back.

At start up the program will load a set of defaults from the file “DefaultConfig.txt”. If you need

a different set of defaults you can overwrite this file with your own values. If you have several

different configurations then these can be saved as separate files.

Before sending data to Netiom-UDP the data is checked for any inconsistencies and will not

proceed if any are found. If problems are encountered a list is written to the logging window.

During the write operation to Netiom-UDP all data is read back and compared with the data

sent. If there are any problems then they will be reported in the log window.

Setting The Address

In order to function properly on a network Netiom-UDP needs know the following information:

IP Address

Gateway Address

Submask

Netiom-UDP  is  able  to  collect  this  information  automatically  if  the  network  has  a  DHCP

server. However if these addresses are obtained automatically they will be dynamic and can

change with time. This may cause an interruption to the link, however it should be restored

automatically.

To  obtain  an  address  automatically  check  the  “Get  Address  Automatically”  box.  After  you

download the data to Netiom-UDP and remove the link Netiom-UDP will attempt to obtain the

relevant information.
