RF150 Communication Option:
The
–RF150 communications option to the RCI series utilizes license-free 150-154 MHz MURS Band
radio frequency transmissions to exchange the signal data between a host and its remote(s). There
are two types of
Topologies
that can be configured: 1) Point-to-Point and 2) Host-to-Multipoint.
In a
Point-to-Point
topology one host
communicates with one remote. The two
exchange all their signals with one another.
The remote is configured as remote #1
even though it is the only remote in the
system.
In a
Host-to-Multipoint
topology one host
communicates to several remotes. Each
remote is assigned an address (1,2,3, etc.)
so that the host may distinguish between
them. There may at most be as many
remotes as there are inputs & outputs on
the host.
For example, an RCI-200, having two
analog/contact inputs and outputs, may
communicate with up to two RCI-100
remotes each having one analog/contact input and output. In this case all
#1 inputs and outputs on
the host correspond to the #1 inputs and outputs on remote #1
and all
#2 inputs and outputs on
the host correspond to the #1 inputs and outputs on remote #2
. The second analog/contact input
and output on each of the two remotes would be unused.
All radio configurations are done via two banks of DIPswitches. SW1 assigns the remote address from
1 to 9 using a binary encoding scheme. SW2 assigns the Topology, Channel ID, Channel Numbers
and Host/Remote Mode. The switches are located on the left side of the communications board. They
are slide type switches that slide
up for ON
and
down for OFF
.
