12 AF-1 and AF-2 fans user manual
A F - 1 1 0 V c o n t r o l i n s t a l l a t i o n
AF-1 fan speed can be controlled by connecting a suitable analog 0 - 10
volts DC controller via the ANALOG IN connector. Up to four machines
can be linked on an analog control link. To create an analog control link:
1. Power fans off.
2. Connect a suitable cable to the controller’s output and the first fan’s
analog input.
3. Use suitable cable to connect the first fan’s analog output to the next
fan’s analog input, and continue connecting fans output to input.
4. Reapply power.

Up to 32 devices can be controlled on one DMX data link. Devices must
be ‘daisy-chained’ in one continuous line without branches. More devices
can be added and the link can be branched using an optically isolated
splitter/amplifier such as the Martin RS-485 Opto-Splitter (P/N 90758060).
DMX cable connection
A reliable DMX data connection requires suitable cable. Standard
microphone cable cannot transmit DMX data reliably over long runs. For
best results, use shielded cable with at least one twisted pair specifically
designed for RS-485 applications. Your Martin dealer can supply suitable
high quality cable in various lengths.
AF-1 and AF-2 fans both connect to a serial DMX data link via XLR
connectors:
• The AF-1 fan has three-pin XLR connectors for DMX IN and DMX OUT.
• The AF-2 fan has both three-pin and five-pin XLR connectors for DMX
IN and DMX OUT.
All DMX connectors on AF-1 and AF-2 fans are wired with pin 1 to ground,
pin 2 to signal - (cold), and pin 3 to (hot). This is the standard pin
assignment for DMX devices.
