WR-5 User Reference

1. Introduction:

The WR-5 is a microprocessor based remote control unit for the Protea 24.24M, Ashly’s multi­channel DSP matrix processor. The WR-5 is designed to fit into a standard electrical wall box for
remote control of assignable 24.24M functions. Each of six buttons on the WR-5 can be pro­grammed to engage one of the following functions: preset recall/scroll, channel volume, mute, or
zone source selection. Programming of each button is done from software, when the WR-5 is con­nected to its host 24.24M, and the 24.24M is in turn connected to a PC using Protea System Software
(version 6.4 or greater). Multiple WR-5 units can be daisy-chained from the same 24.24M for
discrete control over multiple locations under the processing control of one 24.24M.

Installations which currently use WR-3 or WR-4 units can integrate a WR-5, but special wiring
requirements apply (see section 3). For new installations, Ashly recommends exclusive use of the
WR-5.

2. WR-5 Features:

The WR-5 can be thought of
primarily as a programmable zone
controller. The physical acoustic space
in which one WR-5 is installed is gener­ally considered one zone, driven by a

24.24M output or group of outputs.

The WR-5 has six programmable
buttons, each with its own status LED.
Button programming is done in Protea
System Software (V6.4 or higher).
There is a pocket in the mylar overlay to
the right of each button for a paper label
to be inserted. The two up/down buttons
adjust overall zone volume level (if
programmed) or individual button
parameters. The numeric LED displays
zone volume level, button/function
values, or status/diagnostic indicators.

On the back of the WR-5 unit, two four pin euroblock connectors are used for data INPUT from
a 24.24M, or LINK for connecting to another WR-5. There is also a two pin jumper labelled “J6”
which requires the provided female jumper to be installed if the WR-5 is the last one in the data
chain.

3. Wiring and Mounting a WR-5:

All wire connections between a WR-5 and the 24.24M use a two-piece euroblock connectors, a
screw-terminal plug for the wire connections, and the mating jack on the product itself.

The WR-5 uses a four conductor

serial bus to connect to the 24.24M and
to subsequent WR-5 units, with a serial
bus termination (WR-5 jumper J6)
required on the last WR-5. Four
conductor telephone wire is suitable, as
well as CAT5, but if shielded wiring is
used be sure to ground the source end.

Under no circumstances should shield­ing be left unconnected to ground, as

the added line capacitance will de­grade the data signal.

Maximum distance to the first

24.24M Data
Connector

WR-5 is <400ft (120m). Maximum
distance from first WR-5 to the next
WR-5 is <1000ft (300m).

Each WR-5 has two four-pin euroblock connectors on the back of the unit, one labeled

“INPUT” and the other labeled “LINK”. Connect the four conductor serial bus wire from the

24.24M to the WR-5 INPUT as follows:

If more than one WR-5 is being used, connect the next length of four conductor bus wire from
the first WR-5’s “LINK” euroblock connector to the following WR-5 “INPUT” connector, and so on,
until the last WR-5 is wired. On the last WR-5 in the chain, even if there is only one WR-5, install
the female jumper on J6 on the back of the pcb to terminate the serial data bus, and make sure all
prior WR-5 units have that jumper removed.

Note: If more than four WR-5 units are required, an external power supply must be used in­stead of the 24.24M +18V supply. See section 6 for details.

Replacing a WR-3 or WR-4 with a WR-5

Ashly recommends using WR-5 units exclusively in new installations. However, where there is
an existing installation of a WR-3 or WR-4 which use the three wire bus format, the following
wiring instructions allow use of a WR-5 with existing wire runs.

1) Wire the “+18V” wire from the 24.24M to the WR-5 input pin 4.

2) Wire the “Data Out -/Gnd” from the 24.24M to the WR-5 input pin 3.

3) Wire the “Data Out +” from the 24.24M to the WR-5 input pin 2

4) Leave WR-5 pin 1 empty, unless the WR-5 is the last in the chain.

5) Subsequent WR-5 units connect with pins 2, 3, and 4 only

6) On the last WR-5 in the chain, connect input pin 1 back to the 24.24M “Data In +” using the
wiring formerly used as the terminating line from the WR-3 or WR-4. Be sure to install the jumper
J6 on the last WR-5 in series.

7) On the 24.24M, connect “Data In -” to “Data Out -/Gnd” as shown at top of page.
