Are you sure about that? If you actually read the Victor 884 data sheet, it definitely sounds like you're supposed to send a 1-2ms pulse with a frequency no greater than 120Hz. A 2ms pulse should be full forward, even though that's substantially less than 50% duty.

It's not quite that easy. You'll need a couple of capacitors and resistors, I'm sure. Search around for 555 circuits, or pick up a copy of Forest Mims' timers and op-amps notebook.
