Re: IR modular jack wiring layout

Colby -

The built-in IR jack uses +12V, but the 25-pin connector has +9V and +5V. I assume that the regulated +5V is used for the IR devices on the expansion board. If this is true, three questions come to mind:

1) Is the IR receiver that came with the slink-e any different than those that ship as "additionals" in order to accomodate the different voltages?

2) Likewise, should I be concerned about plugging IR transmitters in to the built-in jack, or will they accomodate both +5V and +12V?

3) Will the built-in jack work better for longer runs that the expansion jacks?

4) Out of curiosity, why was this done? Off-hand, it would seem that uniformity between jacks would be desireable.
