VertX V1000 (CS) Quick Installation Guide
4
. RS-485 Connections –
The V1000 has
two - RS-485 connectors and uses the 10-
pin connector on
P3
and
P4
. Each RS-485
bus can support a maximum of 16 V100-
Series panels using one or two ports.
Having two ports on each bus provides the
option of splitting each RS-485 bus into two
physical connections, allowing a total of
four physical connections for the two
busses.
RS-485 busses must be connected in a
daisy chain topology and not a star
topology.
The V1000 termination jumper should be in
the
Out
position if there are no panels
attached to that port. If there are
downstream panels attached then the
termination jumper should be in the
In
position.
CAUTION:
The V1000 RS-485 Ports 1 and 2 (P1) are a common bus and therefore cannot have
panels with duplicate Interface Addresses assigned. The same is true of the V1000 RS-485,
Ports 3 and 4 (P4). For example, two panels, both with Interface Address 0 (factory default),
cannot be connected to Ports 1 and 2 (P1).
It is recommended to wire the RS-485 to the
In
position of the P9 terminal block of the V100-Series
panel. This is especially important when the RS-485 communication is in a “daisy chain”
configuration. If the RS-485 is wired
In
and
Out
, and power is lost, or the P9 terminal block is
unplugged on a V100-Series panel, RS-485 communications will be lost to downstream V100-
Series panels.
