2.
Tip the MAC 600/E on its side or install the clamps while the fixture is in the flight case.
3.
Align a clamp with 2 mounting points. Insert the fasteners into the base and turn both levers a full 1/4turn
clockwise to lock. Install the second clamp.
4.
Verify that the structure can bear at least 10 times the weight of all installed fixtures, clamps, cables, auxiliary
equipment, etc.
5.
Working from a stable platform, hang the fixture on the truss. The front is indicated by an arrow on the base.
6.
Install a safety wire that can bear at least 10 times the weight of the fixture. The attachment point is designed
to fit a caribiner clamp. Never use the carrying handles for secondary attachment.
7.
Tighten the rigging clamps securely to the structure.
8.
Verify that there are no combustible materials or surfaces to be illuminated within 1 meter of the fixture, and
that there are no flammable materials nearby.
Connecting the serial link
Ti p s f o r b u i l d i n g a s e r i a l l i n k
1.
Use shielded twisted-pair cable designed for RS-485 devices.
Standard microphone cable cannot transmit
control data reliably over long runs; use only cable designed for RS-485 applications. 24 AWG cable is suitable
for runs up to 300 meters (1000 ft). Heavier gauge cable and/or an amplifier is recommended for longer runs.
2.
Never use a “Y” connector to split the link.
To split the serial link into branches use a splitter such as the
Martin 4-Channel Opto-Isolated RS-485 Splitter/Amplifier.
3.
Do not overload the link.
Up to 32 devices may be connected on a serial link.
4.
Terminate the link
by installing a termination plug in the output socket of the last fixture on the link. The
termination plug, which is simply a male XLR connector with a 120 ohm, 0.25 watt resistor soldered between
pins 2 and 3, “soaks up” the control signal so it does not reflect back down the link and cause interference. If
a splitter is used, terminate each branch of the link.
C o n n e c t i n g f i x t u r e s
The MAC 600/E has locking 3-pin data input and output sockets that can be configured for use with either DMX or Martin
Protocol controllers. 7KHGHIDXOWSLQRXWLVFRQILJXUHGWRWKH'0;VWDQGDUG, i.e., pin 1 to shield, pin 2 to
signal (-) and pin 3 to signal (+).

1.
Connect the controller’s data output to the MAC 600/E’s data input. For a
•
DMX controller with 5-pin output:
use a cable with 5-pin male and 3-pin female connectors such as
P/N 11820005. Pins 4 and 5 are not used.
•
DMX controller with 3-pin output:
use a cable with 3-pin male and female connectors such as the one
supplied.
•
Martin RS-485 Protocol controller
: use a phase-reversing cable, such as P/N 11820006, with 3-pin
male and female connectors or reconfigure the XLR output.
2.
Continue the link: connect the output of the fixture closest to the controller to the input of the next fixture. Use
a phase-reversing cable when connecting a DMX-standard (pin 3 +) device to a Martin-standard (pin 3 -)
device.
