Determine Your Requirements
Serial Ports are used to interconnect other
dimmers, smart control panels, sensors and
AV controllers. Serial port devices can be
identified by 4 terminals, labelled: GND,
DATA+, DATA-, +VE.
Serial Cable Connections
There is one RS485 port for DyNet signals, in
the form of a RJ12 socket, on the front panel,
which is used for the temporary connection of
a PC or a Portable Programmer. There are
data terminals on the control card, for
permanent connections. The recommended
cable for connections to the serial port is
screened, stranded RS485 data cable with
three twisted pairs. Recommended cable
types include:
Belden: 9503
Dynalite: DYNET-STP-CABLE
Garland: MCP3S
Hartland: HCK603
M&M Cable: B2003CS
M&M Cable: B9503CS
Multicables: AWM E120236 2092 20
RS Components: 368-687
Dynalite DYNET-STP-CABLE
One pair is paralleled for GND, one pair paralleled for +VE,
and one pair used for DATA+ and DATA-.
Recommended Cable Colour Coding
Green/White pair
Orange/White pair
Blue/White pair
Brown/White pair
The colour-coding scheme used is not critical,
as long as the same scheme is used
throughout the installation.
Serial Cable Connecting Method
The recommended connecting method is to
'daisy chain' devices (ie. starting at the first
device, then looping in then out of devices,
with a single cable terminating at the last
device. There should not be any spurs or
stubs, and only the first and last device
should terminate 1 cable, all other devices
should terminate 2 cables). Devices may be
wired in any order. The Data Cable should
be segregated from any Mains Cables by
30mm. A data cable that is connected to an
energised dimmer is live. Do not cut or
terminate live data cables. If the data cable
has to cross over any mains cables, it should
do so at a 90° angle.
