Connection with the master system is made with Ethernet cables consisting of four pairs of

twisted pair wires (screened). The card is connected on one end while the corporate network's

electronics (hub or switch) is connected on the other end.

If a computer or device is directly connected through its Ethernet port, the Ethernet cable wiring

should have a special provision for said communication.

It is also possible to configure the

CVMk2's expansion card IP address using Power Studio or

PowerStudio Scada by CIRCUTOR. (Said software can be downloaded from www.circutor.

com).

Once installed, the

CVMk2 Ethernet Modbus/TCP device should be selected, as illustrated in

the figure:

In this menu you can configure all options of CVMk2 ethernet card. Once the desired

configuration exit the application must exit saving changes

The speed set in the configuration menu CVMk2 ethernet port must match the

speed configured on the device itself (see chapter 4.6 Communications). If no

match, the device did not communicate properly with the application or master.

a) Once that is done, enter the following command to assign the IP address to the

expansion card connection.

c:\ arp -s 172.16.14.254 00-20-4A-8D-66-66

b) Now, execute a telnet to port 1. ( For some versions of Windows the command Telnet

come deactivated). The connection attempt will always fail, but the

CVMk2 will change

its IP to the one previously assigned.

c:\ telnet 172.16.14.254 1

c) Finally, execute a telnet to port 9999 and configure all the required parameters. Then,

it is possible to begin configuration of the expansion card's Ethernet converter. It is

very important to save the changes before exiting the configuration menu. Example:

c:\ telnet 172.16.14.254 9999

The configuratios screen is as follow
