The next step is the definition of the connections table in which the physical
connection point of each I/O device is defined. During this procedure the host is
informed about the addresses of the RTUs existing on the particular channel, and
which I/O devices are connected to each.

SETTING UP THE INTERFACE AND THE RF MASTER
The RF INTERFACE has been designed to support the GIII and GIV versions, but it
can be compatible with older versions as well. When used with the previous
generation MASTER (up to version 7.8) jumper JP6 should be set to
can be compatible with older versions as well. When used with the previous
generation MASTER (up to version 7.8) jumper JP6 should be set to
“OLD” position
and when us
ed with a MASTER of version 7.9 or higher, JP6 should be in “NEW”
position (see picture below). Talking about compatibility it must be pointed out that
Master of version 7.9 or higher cannot work properly with interface of the old
generation, therefore if there is a need to replace a Master of version 7.8 or lower
with a Master of version 7.9 or higher it forces the replacement of the old RF
interface to the new one as well.
To indicate that the system contains analog inputs that are supposed to be read
through the RF RTU system, JP13 must be set in left position, leaving the right pin
free as in the picture below.
