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

Tips for building a serial link

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 recom-

mended 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 sol-

dered 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.

Connecting fixtures

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. 7KHGHIDXOW SLQ RXW LV FRQI LJXU HG WR WK H'0; V WDQG DUG, 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 fix-

ture. Use a phase-reversing cable when connecting a DMX-standard (pin 3 +) device to a Martin-stan-

dard (pin 3 -) device.

3. Insert a male 120

Ω

XLR termination plug in the output of the last fixture on the link.
