Stand-alone Setup
When the Compact Par 7 Tri is not connected to a controller or to other devices, it functions as a stand-
alone device. It can be operated manually, in auto mode or in sound-controlled mode.
For more information about the control modes, refer to 6.2. Control Modes on page 17.
DMX Connection
DMX-512 Protocol
You need a DMX serial data link to run light shows of one or more devices using a DMX-512 controller or
to run synchronized shows of two or more devices set in a master/slave operating mode.
The Compact Par 7 Tri has 3-pin DMX signal IN and OUT connectors.
The pin assignment is as follows: pin 1 (ground), pin 2 (-), pin 3 (+).
Devices on a serial data link must be daisy-chained in a single line. The number of devices that you can
control on one data link is limited by the combined number of the DMX channels of the connected
devices and the 512 channels available in one DMX universe.
To comply with the TIA-485 standard, no more than 32 devices should be connected on one data link.
In order to connect more than 32 devices on one data link, you must use a DMX optically isolated
splitter/booster, otherwise this may result in deterioration of the DMX signal.
Note:
● Maximum recommended DMX data link distance: 300 m
● Maximum recommended number of devices on a DMX data link: 32 devices
