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 ampliers, ne8800 and ne4800 system processors, the  ne24.24M matrix processor, and all models of the NE multichannel (four or eight channel) power  ampliers.  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 specic 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

down block connection, then back out from there to the next WR-5 data input (J2 pin 2), out J2 pin  1 of that WR-5 back to yet another isolated punch down block connection, and so on, with the last  WR-5 Data Output (J2 pin 1) wired back to the host unit’s Data In connection.  In this type of cen-
tralized wiring scheme, every WR-5 that returns its data signal back to the punch down block using J2 pin 1 must have its J6 jumper installed.  Without the J6 jumper installed, the data input signal on 
J2 pin 2 is routed to J3 pin 2 for WR-5 series wiring as illustrated above.  Maximum cable length for  data integrity is 1,000 combined feet between any two active units.
When more than four WR-5s are being used, an external DC power supply is re-
quired.  The power supply must provide at least 13VDC and no more than 35VDC.  In addition, each  WR-5 requires 30mA of current, (or 0.03 Amperes).  To determine the minimum current rating of the  power supply in mA, multiply 30 times the number of WR-5 remotes to be used (Note: 1000mA =  1A).  
Ashly offers an Inline Power Booster called the RPS-18 that provides 24VDC and 625mA  maximum current.  It has common, euroblock-style terminals for easy insertion between the host  data port and WR-5 Input jack.  Alternatively, it can be inserted between the J3-LINK jack of any  of the rst four WR-5 remotes, and the J2-INPUT jack of the next WR-5 in the chain.  This latter  application can be useful to overcome voltage losses, caused by long cable runs to multiple remotes.   In either application, do not connect the +18V pin from the host unit’s Data connector to the exter- nal supply +18V.  It is possible to use the host unit’s +18V for the rst four WR-5 remotes and then  supplement any remaining WR-5 remotes with the inline power booster.  Always connect the exter-
nal power supply ground to the host unit’s Data connector ground.
Cable Length - Two things to consider when running cable to the WR-5 are data integrity 
& power supply voltage.  Active buffers (line drivers) in the WR-5 maintain data integrity, allowing  up to 1,000ft (304m) of cable between devices.  Thus, a maximum cable length up to 1,000ft may be  used between the Remote Data Port and WR-5 remote, and another cable up to 1,000ft may be used  from the WR-5 Link jack to an additional WR-5 remote, and so on. Hence each WR-5 functions as a  data repeater.
However, long cable runs act as resistors, which reduce the DC power supply voltage delivered  to the WR-5.  Each WR-5 requires a minimum of 13VDC measured across J2-INPUT jack terminals  3 & 4.  It is vital to keep track of the power supply voltage drop across each successive cable run to  those pins.  For example, typical CAT5 (24AWG) wire has a DC resistance of 0.026 ohms per foot.  Since there are two conductors, (V+ and GND), the resistance is doubled to 0.052 ohms per foot.  Therefore, voltage drop across CAT5 wire can be computed as: 
Voltage drop = current (in Amps) * 0.052 (ohms) * cable length in feet
Where current is computed at 30mA (0.03A) per WR-5.  If the supply voltage at the WR-5 falls  below 13VDC, the WR-5 will not power up.  TIP: To minimize voltage loss over cable length, use
multiple conductors for V+ and GND, (WR-5 terminals 3 & 4). For example, CAT5 wire has a total of eight 24AWG conductors. Use one pair for wiring up the two data terminals. Use three conduc­tors in parallel for V+, and use the three remaining conductors for GND. This effectively reduces the power supply voltage drop by a factor of three.

3. Getting Started
The WR-5e comes with all function buttons set to “Off”.  To program from a PC running Protea 
NE Software, follow these steps:
1)  Connect a PC running Protea NE Software to the host NE product using a standard ethernet 
RJ-45 cable.
2)  Connect the rst WR-5e to the NE product’s data connector as shown, installing the jumper 
on J6 if it is the only WR-5.
Upon connecting and powering up the system, the WR-5e will have a “heartbeat”, meaning an  internal small green LED on the PCB will be ashing.  As a WR-5 powers up, the LCD rst shows  the two digit rmware revision, then once communication with the host is established the WR-5e  displays “- -” in the LCD window.  If there is a two-digit number showing in the LCD, that means  the WR-5 has been previously programmed to control a zone and that number is the gain level for  that zone.
In the Protea NE software window, the WR-5e will appear in an expaned menu of its host unit  in the left side listing on the screen.  Individual NE products and their remote control units can be  dragged onto the project canvas to simulate physical rack and room installation groups, but editing  each product can be done from either the product list or the canvas.  Once an image has been placed  on the canvas, it must be deleted by hand if that device is no longer available to the software.  Scan­ning for devices does not automatically remove images which may have been installed at one time  but are now off line.  However, in the NE system menu at the left side of the screen, an ofine host  unit will appear in red text while an online unit appears in green.   Further WR-5 help is available
by opening the WR-5 device and pressing F1, or by navigating through the software Help menu.
The project canvas is used to visually represent and control a xed physical sound system  installation, and can display all Ashly NE processors, ampliers, and remotes used in that system.   Lines, rectangles, text, and image les can be added to create a custom virtual control screen along  with the NE products and individual control objects.  To see all available canvas tools, right click  anywhere over open canvas.  Checking <Design Mode>  allows placed objects to be moved around,  while unchecking <Design Mode> locks objects in place.
4. Programming the WR-5e
Protea NE software is able to determine from the host product which functions are available for  WR-5 control, as not all functions listed below are available on all NE products.
1)  Off - No function assigned and the button’s LED remains unlit
2)  Preset Recall - A single preset number is assigned to a button.  When the button is pressed,  the recalled preset number and the letters “PC” are alternately ashed on the WR-5 for seven sec­onds, also locking out any other WR-5 action for that time.
3)  Preset Scroll Mode - A range of presets can be assigned to a button and selected by press­ing and holding the up/down buttons.  Upon release of the up/down button, the displayed preset will  load.  The button’s LED will ash for the duration of the preset scroll operation.
4)  Gain Control - Ashly NE products with Hot-Plug DSP processing must have an (ne)WR5  Remote Gain block placed in software on the channel(s) whose gain is to be under WR-5 control.

Operating Manual - WR-5e Remote Control for NE Products
Since there are many possible gain adjustment points within the various NE products, the  WR-5 displayed gain level is only a relative adjustment for that WR-5.  In other words, gain could  be changed elsewhere in the host unit, independent from WR-5 control.  The WR-5 can adjust gain  from a relative 0 to 99, and an upper and lower number limit can be set in the function range section  to limit the maximum and minimum reach of that control.  
When a gain control button is pressed, its LED ashes and the up/down buttons determine gain.   If the up/down buttons remain idle for ve seconds, the gain button becomes inactive until being  pressed again.  
If a Zone Output is active for that WR-5, meaning one or more output checkboxes are selected  within the Zone Setup area, the WR-5 up/down buttons and numeric display will revert (after ve  seconds of inactivity) from the individual button gain mode to the overall output gain adjust mode  for that zone.  If no output is selected for that zone, the display shows “--” as the default.
5)  Channel Engage/Mute - A button can be congured to engage or mute a channel or group 
of channels.  The button LED is on when the channel(s) are engaged on.
6)  Zone Source Selection - This is used to select one or more inputs for the zone under WR-5  control.  When multiple zone source select buttons are assigned uniquely different or overlapping  inputs, each button will simply add to or subtract from the other’s input selections, unless the Ex­clusive Source Selection box is checked in the zone setup, in which case only the current button’s  selected inputs will be used.
The Disable Zone Level Control software checkbox allows input source selections to be  changed from the WR-5, but not the output gain.  The output gain can still be adjusted from soft­ware, but the WR-5 user is locked out from making zone output gain changes.
7)  Logic Output Active High - This allows the user to toggle the Logic Output assigned pin to 
the button.  The LED is on when the output is High.
8)  Logic Output Active Low- The LED is on when the output is Low.
9)  Matrix Mixer - This is used to select one or more inputs for the zone under WR-5 control, 
and allows level control of that group at the dsp matrix mixer point.
