Creating a data link
Fixtures on a serial data link must be daisy-chained in one single line,
maximum 500 meters (1640 ft.) long, with maximum 32 fixtures. To
exceed 32 fixtures or 500 meters, or to add branches, an optically isolated
amplifier-splitter such as the Martin RS-485 Opto-Splitter (P/N 90758060)
must be used.
A reliable data connection requires suitable cable. Standard microphone
cable cannot transmit DMX data reliably over long runs. For best results,
use cable specifically designed for RS-485 applications. Your Martin
dealer can supply suitable high quality cable in various lengths.
Data cable can be connected to the Ego X Series via XLR connectors on
the control panel that are wired with pin 1 to ground (earth), pin 2 to
signal - (cold), and pin 3 to (hot). This is compatible with the
standard for DMX devices.
One or more adaptor cables may be required to connect fixtures to the
controller and/or other types of fixture, because some devices have 5-pin
connectors and others may have reversed signal polarity (pin 2 hot and
pin 3 cold). Signal polarity is normally indicated on the fixture.

1. Connect a suitable cable to the DMX output of the controller. If
connecting to a controller with a 5-pin XLR output, use a 5-pin male to
3-pin female adaptor (P/N 11820005).
2. Connect the cable to the male XLR data input of the first fixture on the
link.
3. Continue connecting fixtures output to input. If connecting two fixtures
with opposing polarity on pins 2 and 3, insert a phase-reversing cable
between the two fixtures.
