This manual describes ETC's EM264 electronics module. The EM264 uses DMX512 control
signal to control dimmers in ETC L86 Installation Racks and L86 Touring Racks . Each column
of dimmer modules in a chassis is controlled by an EM264 near the top of the column.
The EM264 allows customized dimmer numbering within the chassis. It can compensate for
a mixture of dimmer types within the same chassis and can customize the control curve for
each dimmer. It can also be configured to allow two consoles to control two sets of lights
independently, or two consoles to control the same lights with highest level taking priority.
Generally, EM264s in installation racks are factory configured to match the requirements of
your system. For portable racks, standard configurations are available without custom
programming. For more details about standard and customized systems, see Configuring the
EM264 on page 3.
Additionally, the EM264 provides optical isolation between input signals and the rest of
your L86 system. The module also isolates the DMX512 input signal between each of the
EM264s .
There are several important differences between EM264 s in installation systems and in
touring systems. The following table lists the most important differences:
Touring Rack
Normal output curve
Standard firing mode
Dual DMX512 ports use highest-level input
120V output
Any DMX512 number can be starting address
Dimmer numbers are sequential, following
starting address

address
The front panel of the EM264 contains eight indicator LEDs that provide you with informa-
tion about your dimming system. When you first turn on your system (or press [Reset]) the
EM264 processor runs a series of self tests. If an error is found, the Error, Quiet, High Volt,
or Low Volt LED flashes and all the other LEDs turn off. See the list on page 2 for informa-
tion about the LEDs.

Page 2: Dip Switches
See Configuring the EM264 , page 3, for more information. DIP switches The DIP switches are used to select a variety of EM264 options. See Configuring the EM264 , page 3, for more information. - Page 3 Configuring the EM264 DIP switches on the front panel allow you to select EM264 options. A switch is Enabled when it is in the up position. It is Disabled when it is in the down position. Setting starting address address Three rotary switches on the front panel allow you to set the starting address for the EM264 .
- Page 4 Enabling Quiet mode The EM264 allows you to operate some or all of your system's dimmers in Quiet mode. Quiet mode can reduce lamp noise significantly in lamps connected to these dimmers. Available only in EM264s in L86 Installation Racks, Quiet mode is most often specified for certain dimmers at the same time the system's configuration tables are programmed at the factory.
- Page 5 Lock protects programmed information in your module. Once you have configured an EM264 , you should leave it locked at all times. Before a module can be reprogrammed, you must disable Lock. Lock is activated by enabling the DIP switch labeled Lock. It is turned off by disabling the switch.

Page 7: Self-Test Mode
Self test mode EM264 ’s Self test mode allows you to run a number of diagnostic self tests. Set the rotary switches as shown below to select the desired test. Press [Reset] to start the test. When you press [Reset], all the LEDs flash three times then turn off (except for the Power LED which stays on throughout all the tests), the EM264 resets and the self test runs. -
Page 8: Watchdog Test
(from 000 to 100). Watchdog test The EM264's Watchdog function monitors the EM264 and restarts the processor if it malfunctions. This test checks the module’s Watchdog function. Set the front panel rotary switches to 960 and press [Reset] to run the test. The LEDs light, then turn off one at a time.
