Ashly WR-5E User Manual
WR-5e NE Product Remote Control
1. Introduction
The WR-5e is a microprocessor based remote control unit for most Ashly NE products. Compatible products currently include Pema ampliers, ne8800 and ne4800 system processors, the
ne24.24M matrix processor, and all models of the NE multichannel (four or eight channel) power
ampliers. Additional products may become available in the future. Using Protea NE software,
six function select buttons and two parameter adjust buttons are available to control a limited range
of assigned functions within their host product. Up to four WR-5e units can be daisy-chained and
phantom powered from one NE product, and even more can be added using an in-line power supply
adapter such as the Ashly RPS-18. Note: If a WR-5e is used with a NE host product, no other serial
communications devices, including the Ashly RD-8C, may be used with that product.
The WR-5e is designed
to t into a European electrical
wall box, but functionally is
the same as the WR-5. Electrical connections to the host
unit are made using a four
conductor low gauge wire
terminated with euroblock
connectors. There is also a
two pin jumper labelled “J6”
which requires the provided
female jumper to be installed
in specic situations (see section 2). A standard decora
plate (not included) can be
purchased separately to cover
the WR-5e electrical box and
satisfy the aesthetic needs of
the installation.
Note: Avoid static shock disruptions to connected devices by mounting the WR-5e to an earthgrounded metal wall box, or by earth-grounding a metal decora plate. This prevents any static
discharge from owing through the data lines.
Each of six buttons on the WR-5e can be programmed through Protea NE Software to engage
one of the following functions (if available): preset recall, preset scroll, gain control, channel engage/mute, zone source selection, logic output active high, logic output active low, and matrix mixer,
with a green LED next to each button to display active status. To the right of each button is a pocket
in the mylar overlay for a paper function label to be inserted. The two other buttons are used to adjust function parameters, indicated by the LED display.

2. Wiring a WR-5e
The WR-5 uses a four conductor
phantom powered serial bus to connect to its host unit or to subsequent
WR-5 units. Up to four WR-5 remotes can be powered from one host
unit. Ashly makes an Inline Power
Booster for use in applications that require more than four WR-5 remotes.
Four conductor telephone wire is
suitable for all wiring, as well as
CAT5, but if shielded wiring is used
be sure to ground the source end of
the shield. Under no circumstances
should shielding be left unconnected
to ground, as the added line capacitance will degrade the data signal.
Wiring in Series: If more
than one WR-5 is being wired in
series, connect the next length of
four conductor bus wire from the rst
WR-5’s “LINK” connector to the
following WR-5 “INPUT” connector,
and so on, until the last WR-5 is wired. On the last
WR-5 in series wiring, and even if there is only one
WR-5, install the female jumper 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.
Maximum cable length for data integrity is 1,000 ft
between the host unit and the rst WR-5, and 1,000
ft between each subsequent WR-5.
Wiring in parallel from a central
location: Some installations are more suited to
wiring multiple WR-5 units from one central location rather than daisy-chaining one WR-5 to the
next. Using a punch down block wired to the host
unit’s data connector, each WR-5 uses one four
conductor cable terminated with a single euroblock
connector originating from the punch down block.
The +18 and Ground connections get parallel wired
to each WR-5 (up to four), but the data signal still
gets wired in series In the following manner: Wire
the host unit’s Data Out (pin 2) to the punch down
block, then out from there to the rst WR-5 Data Input (J2 pin 2), out J2 pin 1 back to an isolated punch
