2. Wiring a WR-5
The WR-5 uses a four conductor 
phantom powered serial bus to con-
nect to its host unit or to subsequent 
WR-5 units.  Up to four WR-5 re-
motes can be powered from one host 
unit.  Ashly makes an Inline Power 
Booster for use in applications that re-
quire 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 capaci-
tance will degrade the data signal.
Wiring in Series:
than one WR-5 is being wired in 
series, connect the next length of 
four conductor bus wire from the first 
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 first 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 loca-
tion 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 first WR-5 Data In-
put (J2 pin 2), out J2 pin 1 back to an isolated punch
