Operating Instructions

The R8 is programmed by sending it MIDI System Exclusive program-
ming messages from a device capable of creating System Exclusive
messages, such as a computer-based MIDI sequencer. These commands are
described in detail on the following pages. For decimal to hexadecimal
conversions, see the chart on page 10. Upon receipt of a System Exclusive
programming message, the MIDI indicator LED turns off briefly and then
flashes rapidly for about one second to indicate that the setting has been
stored. Settings are retained in non-volatile memory until reprogrammed with
new settings.
Connect the In of the R8 to the MIDI Out of the device being used to
program the R8. This is the only connection necessary when programming the
R8 (the MIDI Out and Rel1-8 may be left disconnected). Once the R8 is
programmed, it may be inserted anywhere in the MIDI setup. The relays
(Rel1-8) can be connected directly to footswitch inputs using standard 1/4"
phone cables. If the relays are being connected to devices other than
footswitch inputs, insure that the switching requirements do not exceed the
relay ratings on page 11. Connect the In of the R8 to the MIDI Out or Thru of
the sending MIDI device. Connect the Out of the R8 to the MIDI In of the
receiving MIDI device. It is recommended that the number of MIDI Solutions
products chained together between any two MIDI devices be limited to five.
The R8’s MIDI Indicator LED will light as soon as the sending device is
turned on, and flashes whenever MIDI data passes through the unit. The R8
responds to MIDI messages according to its programmed settings described
on the following pages. All MIDI messages appearing at the MIDI input are
sent to the MIDI output. The relays retain their present state when power is
removed from the unit.
