REMOTE CONTROL PCB
The IWA Series can be remotely
controlled via infrared, wall-mount, or
custom controls (see pages 2 & 3).
Remote control capability is provided
by an optional (user installed) Remote
Control PCB (printed circuit board).
The Remote Control PCB allows
remote control of Main & Zone Output
levels, as well as switching of three
relays (included on circuit board).
Connections are provided for up to two
remote controls, which may then be
assigned the necessary functions for a
specific location or application. A nonvolatile memory allows storage & recall
of up to eight presets (levels & relays).
The Remote Control PCB is installed at
the lower-left of the mixer PCB (see
diagrams). Remove two jumpers from
both P4 & P5 (on mixer PCB), and
screws from the four stand-offs. Mate
receptacles J4 & J5 (on rear of Remote
Control PCB) to P4 & P5, and secure
the PCB with the four screws. A power
wire harness is tie-wrapped to the
mixer wire harness. Cut tie-wrap and
push connector onto J1 (at upper-right
of PCB). Connections for remote
controls are provided at the lower-right.
The "normally open" contacts for three
DPDT relays are provided at the upperleft ("normally closed" contacts are
provided as wiring pads next to each
relay). The relay contacts are rated for
5 Amps max.
The Remote Control PCB provides an
infrared receiver at the right edge (IR1)
for "set-up" purposes (see page 2).
After set-up, this receiver may be
disabled via the adjacent jumper (J6).
Two jumpers are provided near the
center of the PCB (J2 & J3). Once
presets have been stored, jumper J3
allows remote control "store" buttons to
be disabled. When power is turned on,
the most current settings will be
recalled, however, jumper J2 allows
preset #1 to be recalled instead. LEDs
indicate status of each relay, as well as
reception and errors from remote
controls. A switch and LED (at bottom
edge) are used to enter "set-up" mode.
