This manual describes ETC’s L86 EMI3M Opto-Isolation module. This L86 component provides optical isolation between input signals and the rest of your L86 system. The EMI3M electronics module is installed in the top left slot of the L86 dimmer chassis. It isolates the DMX512 input signal from each of the L86 EM64 control modules, and also provides isolation between the EM64 modules.
