Using LAN
Controlling the Relay – 8 can also be done over LAN. This
is done by creating a TCP connection from the control
system to the control port (Default 5000).
The protocol that is used to control the Relay – 8 over
LAN is the same as used when controlling it by RS232.
See the section on page 14. When connecting to the
Relay – 8 control port, the RS232 control on RS232 port
one is disabled.
Controlling an electrical screen or lift
The Relay – 8 offers you the possibility to control up to
four electrical screen and lift directly by 240VAC. When
controlling electrical screen and lift we always recom-
mend that you use two relays. One relay for screen up
and one relay for screen down (In a configuration called:
mutual blocking). Here you can see how to connect your
screen to the Relay – 8.

When making the above configuration you add an extra safety level to your installation. The mutual
blocking prevent that power can be connected to both up and down at the same time.
How you control this configuration depends on the way you connect it to you control system. In
the previous three sections, you can find information on the three types of control you have.
How to control Switching Relay – 8 through USB
After Project Designer 1.6.4 it is possible to control and configure the Switching Relay - 8
through USB the same way you do today with RS232.
When connecting the Switching Relay - 8 to your computer it will be installed as a RS232 port
on your system (The Windows driver is already included in the Project Designer software). Choose
your favorite hyperterminal program or simply open the device driver in the Device Editor and use
it to send the commands.
