Introduction 5
I NTRODUCTION
Thank you for selecting a Jem AF series fan.
The AF-1 MkII™ and AF-2™ fans are powerful machines designed for
professional and semi-professional use in clubs, TV studios, theaters and
touring contexts. They are suitable for a wide range of applications
including smoke and haze dispersal, sending smoke through ducting,
wind effects and cooling performers or equipment. When fans are used at
high output in conjunction with a smoke machine at low output, a perfect
haze effect can be produced.
Both fans have high quality sealed motors designed to withstand the high
condensation levels associated with close proximity smoke
AF-1 MkII™ and AF-2™ fans can be controlled using the remote control
unit supplied with each product or via DMX on a serial data link. They may
be interfaced with all Martin and Jem smoke machines to allow
simultaneous smoke and fan operation.
When used in combination with smoke machines, etc., DMX control
allows atmospheric effects to be integrated in the light show directly from
the lighting console. The remote control allows variable fan speed in
continuous or timer operation. When using the built-in timer, operating
periods and intervals between operating periods can be set
independently.
AF-1 MkII™ and AF-2™ fans can be installed at any angle.
The most recent version of this manual is available under Smoke in the
Support area of the Martin website at: http://www.martin.com

Installing control hardware 11
I NSTALLING CONTROL HARDWARE
The AF-1 MkII™ and AF-2™ can be operated either using the Jem
multifunction remote control unit supplied with each machine, or via DMX
using a DMX control device and serial data link.
Remote control installation
To connect the remote control unit:
1. Power the fan off.
2. Plug the XLR connector on the remote control cable into the REMOTE
IN plug on the connections plate (see “Connections panels” on page
4).
3. Reapply power.
The AF-2 touring frame available as an accessory includes a docking
station for the remote control unit (see illustration below). The remote
control can be fastened in place using the two thumbscrews provided,
and the remote cable wrapped around the brackets.
DMX installation
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).

12 AF-1 MkII™ and AF-2™ user manual
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 MkII™ and AF-2™ both connect to a serial DMX data link using
either their 3-pin or their 5-pin XLR DMX In and Out connectors. DMX
connectors are wired with pin 1 to ground, pin 2 to signal - (cold), and pin
3 to signal + (hot). This is the standard pin assignment for DMX devices.
To connect the DMX data link:
1. Power all devices off.
2. Connect a data cable from the controller’s DMX data output to the first
device’s DMX input
3. Connect the DMX output of this device to the DMX input of the next
device.
4. Continue connecting up to a total of 32 devices in one single line,
output to input.
5. Terminate the link by inserting a male termination plug (available from
your Martin dealer: P/N 91613017) into the data output of the last
device. A termination plug is simply an XLR connector with a 120
Ohm, 0.25 W resistor soldered across pins 2 and 3.
Specifying DMX control channels
AF-1 MkII™ and AF-2™ use a single DMX control channel to receive
instructions from the controller. This control channel is the DMX address.
To control machines individually, each must have its own unique DMX
address. To control identical machines as a group, they can all be given
the same DMX address. They will then receive the same instructions and
should behave identically. Setting up identical fixtures with the same DMX
address can also be a good tool for troubleshooting unexpected behavior.
The DMX address on AF-1 MkII™ and AF-2™ fans can be set to any
channel from 1 to 511 using DIP-switch pins 1 - 9. To set the DMX
address:
1. Decide on an available DMX address for each machine.
2. Look up the DIP-switch settings using the Martin Address Calculator at
http://www.martin.dk/service/utilities/AddrCalc/index.asp, or look for
the address in the DIP-switch settings table on page 13. For example,

Installing control hardware 13
to set the DMX address to 101, you need to set DIP-switch pins 1, 3, 6
and 7 to ON, as shown in the illustration below:
3. Power the controller and all devices off.
4. For each device, set the DMX address by setting DIP-switch pins 1
through 9 to the ON (1) or OFF (0) position as listed in the table on the
next page. As an example, channel 101 is highlighted in the table.
DMX address DIP-switch settings
To use Table 2, first find the DMX address in the main block in the table.
Then read the settings for pins 1 - 5 to the left and read the settings for
pins 6 - 9 above the address. “0” means OFF and “1” means ON.

14 AF-1 MkII™ and AF-2™ user manual
For example, to set the DMX address to 101, you need to set DIP-switch
pins 1, 3, 6 and 7 to ON, as highlighted in the table.
DIP-Switch 10 test function
DIP-switch 10 allows testing without a remote control or DMX signal. If you
switch it to the ON (1) position, the fan runs at full output for 2 seconds.

Operation 15
O PERATION
Before powering on, check that the fan is correctly and safely installed.
Using fans with smoke machines
When using a fan in
combination with a
smoke machine, fog
machine or hazer,
place the fan behind
the machine, as
illustrated on the
right. Do not place
the fan in front of the
machine and direct
the output from the
machine into the fan,
as this will cause
undesirable moisture
and residue build-up.
The fan blades will
also degrade the
quality of the smoke.
Using fans with smoke ducting
For best results and easy directional control, connect fans to smoke
ducting using a Y-shaped arrangement, placing the fan on one arm of the
Y and the smoke machine on the other.

Operation 17
Timer operation
The automatic timer sets the AF-1 MkII™ to produce timed fan bursts at
regular intervals. You need to set two times: the run/on time during which
the fan will run, and the wait/off time during which the fan will switch to
idle. To set up timer operation:
1. Press TIMER SET. The ON LED will flash. You are now setting the
On/Run time.
2. Turn the LEVEL / TIMER control to the required "run" time, as shown
on the scale (OFF - 255 seconds).
3. Press TIMER SET once. The ON LED will light constantly and the
OFF LED will flash. You are now setting the Off/Wait time.
4. Turn the LEVEL / TIMER control to the required "wait" time (OFF - 255
seconds).
5. Press TIMER SET once more. Both ON/OFF LEDs will light to show
that the timer is programmed.
The run and wait times are now stored and will be remembered even after
the unit has been powered off.
To start the timer using the times you have set, press RUN / TIMER
ENGAGE briefly. To turn off the timer, press RUN / TIMER ENGAGE
briefly again. When the timer is engaged, the ON LED lights during the
On/Run time and the OFF LED lights during the Off/Wait time.
Additional functions:
• If you only want to change the Off/Wait time, leaving the On/Run time
unchanged, press TIMER SET twice. This will take you directly to
setting the Off time without changing the On time.
• To find out what the current time settings are, press TIMER SET then
rotate the LEVEL / TIMER control slowly until the "ON" LED begins to
flash very rapidly. The control is now set to the current run/on time.
Press TIMER SET once and rotate the control slowly again until the
"OFF" LED begins to flash very rapidly. The control is now set to the
current wait/off time. Press TIMER SET again to return to normal
operation.
“One-shot" operation
“One shot" operation lets you run a fixed-time fan burst at will by pressing
the RUN button. To set up “one-shot” operation:
1. Press TIMER SET. The ON LED will flash. You are now setting the
On/Run time.

2. Turn the LEVEL / TIMER control to the required "run" time as shown
on the scale (OFF - 255 seconds).
3. Press TIMER SET once. The ON LED will light constantly and the OFF
LED will flash.
4. Turn the LEVEL / TIMER control fully right to "OS" ("One Shot").
5. Press TIMER SET once more.
The timer is now programmed to one-shot mode and this will be
remembered even after the unit has been powered off.
To produce a timed fan burst, press RUN briefly. To stop the timed burst
early, press RUN briefly again.
