I wonder can anybody help. I have a Denon cd receiver with a remote
control. Connected to it I have an Onkyo cassette deck. Both
machines have mini jack plug
sockets for remote control interconnection. Will the Denon (which has
the infrared sensor) control the Onkyo? Would connecting them be
likely to cause any damage?

As an alternative approach, would a "universal" remote be of any use?

I'd be very grateful for any advice.

Unlikely

Possibility of damage, yes.

Nope. Your cassette deck is blind - it won't see it!

However, some remote control bus systems simply distribute the
demodulated serial stream transmitted from the IR remote around the
addressable internals of the equipment (e.g. RC-5/I2C), others
communicate with a central microprocessor that resends rather more basic
controls signals specific to each peripheral device.

If it's the former - a distributed system, AND the IR carrier frequency
& modulation method is the same for both Denon/Onkyo, AND the bus
addressing is compatible, AND you can get the two boxes to electrically
connect without fireworks than that is a _very_ long shot of working
using the two original IR remotes, or one universal.

Someone with a knowledge of hacking with digital control logic,
equipment schematics, a scope and a PIC programmer would be able to sort
this out, but the development time would cost more than the equipment. :-(
