The 1/3 and 2/4 jacks are 1/4" stereo
(tip-ring-sleeve) jacks. If you plan to only use 2 of the 4
relays available then you can simply plug standard mono cables
between the FootSim and the Amplifier or device you wish to
control. In this case only relay 1 and 2 are accessed. To use
all 4 relays, use a stereo cord or stereo to dual-mono Y style
cord in each jack.
The Last Indicator illuminates if the last
relay selected switches to an "on" state and extinguishes if the
relay goes to an "off" state. This is a convenient indication of
the state of the most recently selected relay.
The Power Indicator lights when DC power
from the module is applied.
The MIDI Indicator flashes whenever the
FootSim sees MIDI data that it recognizes and uses on its own
channel. This is an indication that the unit has just responded
to a command.
The MIDI In Jack connects to a standard foot
controller or the MIDI data stream.
The MIDI Thru Jack passes all MIDI data
through undisturbed.
The Power Jack connects to the supplied power module and
operates at 9V DC @ 100ma with the center pin positive.
The FootSim measures approximately 5-1/2" X 3" X 1-1/2" in size.
The PowerSwap can be controlled either by
MIDI Program Change commnads or by Control Change commands
(Instant Access Switches) as are commonly found in some modern
foot controllers. Below shows how various Program numbers
control the relays.

This next chart shows how Control Change
numbers are used to control the relays. Control Change is the
mechanism used in "Instant Access" Switches.
