Connect Data Cable in a 'Daisy Chain'
RJ12 Socket Connections
Serial Cable Permanent Connections
Determine Your Requirements
Serial Ports are used to interconnect dimmers,
other control panels, sensors and AV controllers.
Serial port devices can be identified by 4
terminals labelled: GND, DATA DATA-, +VE. On
the DTP100 connect to Port 1 closest to the
RJ12 Connector.

Serial Cable Connections
There is one RS485 port for DyNet signals, in the
form of a RJ12 socket, on the rear, which is used
for the temporary connection of a PC or a
Portable Programmer (DPP601). There are data
terminals on the main PCB, for permanent
connections.
The
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
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:
The colour-coding scheme used is not critical, as
long as the same scheme is used throughout the
installation. The shield should be terminated in
the "SHIELD" terminal if present, otherwise it
should be terminated to the metal chassis of
electrically earthed devices, and looped through
on devices that are not electrically earthed.
Serial Cable Connecting Method
The recommended connecting method is to
„daisy chain‟ devices (starting at the first device,
then looping in then out of devices, with a single
cable terminating at the last device.
should not be any spurs or stubs, and only the
first and last device should terminate one cable.
All other devices should terminate two cables).
Devices may be wired in any order. The data
cable should be segregated.
