I'm guessing that those 1/8" emitters are just "dumb" emitters, and almost
surely they can be connected to act just like an LIRC homebrew serial
transmitter.  Most likely only with three plain 'ole wires, but possibly a
series resistor might be needed.  (depending on if the emitter assembly already
has a resistor.)
