Description of Operation
Presidor™ Wall Stations (PWS) are designed to support up to 15 stations per room/zone wiring in a daisy-chain
topology. There must be a Main Station in each wiring LAN (Local Area Network) with one Main PWS per room/
zone. Each LAN and Main PWS may have up to 14 Secondary PWS’s connected to it. The Main PWS will output
DMX data for the room directly to the DMX receiving device or to a DMX input of a Presidor™ Room Linker
Combiner (PRLC-4) in a multi-room application.
Installation
There are two models of PWS, both are available in white or black.
Model# PWS-70P-DMX For use in applications where 2 shielded twisted pair wiring capable of
DMX512 protocol exists.
Model# PWS-20P-RETRO For use in legacy installations using analog wiring.
Although both models share the same operation, the station hardware, installation and wiring of each is slightly
different due to the different data protocol used.

WWW.JOHNSONSYSTEMS.COM 7
Model PWS-70P-DMX
Model #PWS-70P-DMX is designed for new applications where CAT5/5e or CAT6 can be provided or retrot
applications where existing shielded 2 or 3 twisted pair wiring capable of RS485/DMX512 exists (eg. Belden
#9773). Capable of up to 70 presets, this model will accept DMX512 on its input and output DMX512 when
congured as a room Main Station. Inter-room communication between multiple PWS will be PMX multiplex
(RS485) protocol. Routine “series” or “daisy-chain” RS-485 topology between multiple station and termination
practices must be followed.
Model PWS-70P-DMX Configuration and DIP Switch Settings
Important! Only one station in each LAN (local Area Network) or room must be designated as a Main PWS (switch 4
ON). Only one Main Station per LAN. All Secondary PWS connected to the Main PWS (maximum 14 PWS) must have
switch 4 turned OFF.
Important! Communication between Main PWS and Secondary PWS is PMX protocol (Presidor™ Multiplex).
This RS485 protocol requires active termination (switch 2 ON) on the rst and the last PWS in the LAN for each
room/zone.

Model PWS-20P-RETRO
Model PWS-20P-RETRO is designed specically for use in Heritage Buildings using existing wiring (typically
analog) not capable of RS485. Communication is performed via a proprietary Unipolar Bi-Directional (UBD) low
baud rate protocol. This permits digital control upgrades to facilities that would otherwise be faced with a very
expensive wiring replacement cost!
Multiple stations must be series or daisy-chained. Minimum of 3 wires is required. No wiring “tee’s” or “starring”
is permitted. This will result in hardware damage to one or more stations and void all warranty claims! Where a
“tee” or “star” must be used, 6 wires to each location shall be required permitting a continuous data and power
daisy-chain between all room stations. No “Tees” or “Star Wiring” permitted! Maximum distance dependent
on wire type and gauge. Typical 1000' or 300m on #18 AWG wiring.
Model PWS-20P-RETRO Configuration and DIP Switch Settings
Important! One station in each wiring LAN must be designated as a Main PWS (switch 4 ON). Only one Main Station
per LAN. All Secondary PWS connected to the Main PWS (maximum 14 PWS) must have switch 4 turned OFF.

Installation Procedure
Each PWS comes complete with a pre-assembled main sub-assembly, wall mounting plate and 6-32 mounting
hardware. PWS is designed for installation into standard grounded single gang electrical backboxes.
1. Ensure the electrical back box is grounded to earth ground via dedicated grounding wiring or through conduit
where electrical code permits. An un-grounded box may lead to damage from static electricity and void
warranty.
2. Clean back box of all debris including metal lings, dust, drywall or any other debris that could affect electrical
performance. Compressed air is best for this.
3. Check the back box 6-32” mount threads before attempting to install the wall mounting plate. This can be
easily done be spinning one of the supplied mounting screws clockwise with your ngers into each of the two
mounting holes. They should install easily with your ngers. If they do not, it is recommended to run a 6-32”
drill tap through the hole with a small reversable drill to “clean out” any bad threading.
4. Install the wall mounting plate ush to the wall and tighten with the supplied mounting screws snuggly as to not
deform the plastic but provide a tight t to the wall. Use a small level to ensure a plumb level installation of the
plate. DO NOT overtighten the mounting screws. Hand tightening is recommended over any power assist tool.
Important: DO NOT exceed 1.5 in. - lbf. for drywall and 5.0 in. - lbf. for Presidor™ Surface Boxes (PSB).
5. Label all wiring as “to or from” for future identication. Dress out all the wiring and terminate to the appropriate
connectors based on installation and PWS model type. Leave at least an 8-12” service loop if possible. Ensure
all wire is stripped back far enough to ensure full plug insertion without insulation. Plug all the terminated
wiring connectors to their nal location on the PWS I/O PCB. Tape off or heat-shrink any exposed shield wiring
or unused conductors that could touch the rear of the station and cause a short circuit.
6. Set the dip switches as required for Main/Secondary PWS, end-of-line termination. See chart on page 7 for
model# PWS-70P-DMX and page 10 for model# PWS-20P-RETRO.
7. Hook the PWS sub-assembly on to the top of the wall plate with the face panel light pipes facing upward.
Gently push to lower the PWS sub-assembly until contact is made with the wall plate. Apply rm pressure
against the bottom of the PWS sub-assembly until an audible “snap” is heard or felt. The PWS sub-assembly
should now be ush to the wall.
PWS Removal
Power OFF the PWS if possible.
To remove an installed PWS, a at head screwdriver with a slot width of 3/16” to ¼” will be required. Insert the
screwdriver into one of the two extraction holes on the bottom of the face panel sub-assembly. Gently and slowly
twist the screwdriver until the face panel “pops” away from the wall mount plate. It may be possible that procedure
is required for both extraction holes. Unhook the top of the subassembly from the top of the wall plate and gently
remove the station from the wall.
Hook PWS onto Wallplate at an angle.
Push down onto Wallplate.
Snap PWS onto Wallplate.

An ADMIN could accidently overwrite
all programmed data.
1. PASSWORD / SECURITY LOCK
Each PWS requires a valid Password entry to access certain functions.
Access via the Security Lock icon, the lock symbol will display red when locked
and no lock symbol when unlocked. Each PWS will default to a “locked” state
with access to only select functions for protection of programing and restriction
of use. A small red lock will appear in the upper left of the display when in
the locked state. Only preset playback and minor edits of preset levels are
permitted in the secure “locked” state.
Each PWS has two passwords to permit controlled access to specic menu
functions:
USER: Factory default “12345” - allows limited access to screens.
ADMIN: Factory default “98765” - allows full access to all screens.
Passwords must always be a 5 digit number. The password is stored in
the removable external EEPROM plug in module on the rear of the PWS.
Passwords are entered at the room Main PWS only and then shared with the
room Secondary PWS via the SYNC command.
Important! On SYNC Main/Secondary, all Secondary PWS will have the same
password as the room/zone Main PWS. The user will not be able to change
the password on a Secondary either manually or with the DIPSW. This function
and option is reserved to the Main Station for the room only.
Password privileges for the PWS are shown below:

2. DMX SETUP
Main PWS DMX set up. ADMIN security access only. This menu is used to set up the DMX mask for each room,
congure the operation of room specic (unmasked) channels, and set the external DMX source input priority in
conjunction with the PWS Main station DMX output.
Pressing the DMX icon in the SETTINGS menu will allow access to the DMX SETUP page.
DIM = Yellow = Dimmer assignment to that specic DMX output channel permitting a full range of DMX control
output from 0-100% from the Main PWS.
ND = Green = Non-Dim assignment to that specic channel permitting toggle between 0% and 100% DMX control
output with a trigger point of approximately 3% DMX.
TASK = Blue = Non-Dim of specic channels for operation within any preset or independent operation outside
of the active preset between multiple Secondary (entrance) PWS stations (room within a room operation). TASK
assignment to a specic DMX channel or group of channels permits toggle (Non-Dim control) between 0% and
100% DMX control output with a trigger point of approximately 3% DMX. “Room with a room” operation is limited
to presets 61-70. Task lights assigned in presets 1- 60 will operate as Non-Dims only on preset execution.
Example: TASK circuit assignment. Several grid blue (safety) light circuits that require control from multiple
entrance (Secondary PWS) locations. The need for all entrance (Secondary PWS) stations to mimic the active
TASK light preset and operate as a “room within a room” without affecting the underlying active preset 1-60 that
the room Main PWS is outputting in DMX.
Below is an example of a 28 DMX channel room conguration where:
• channels 1-11, 13-15, 17,18, 21-24 are set as Dimmers (DIM).
• channels 12, 16, 19 & 20 are set as Non-Dims (ND).
• channels 25- 28 are set as Non-Dim TASK lights (TASK).
Menu down arrow above will access DMX output channels in groups of
32 channels per page up to 512 channels.
