The Pocket Console ®
Wall Mount ™
Installation Instructions
Overview
This document outlines the installation and operation requirements
of
The Pocket Console® DMX Wall Mount™ unit.
The Pocket Console® DMX Wall Mount™ is a single control point for controlling a DMX-512 compatible
dimmer rack(s) and/or other DMX-512 capable devices. If more than one control location is required,
some means of combining control signals is necessary. Please contact us for suggested after market
solutions, if multi-station functionality is desired.
The unit requires very few things to function reliably. These items will be detailed in the following text.

USITT DMX-512 1990 standard dimmer rack or another DMX-512 operated device.
9Volt DC power supply (PS-1 included)
Proper wiring between the components. Belden 8471 (for 9vdc) & Belden 9729 (for dmx)
Proper electrical grounding
Programming (see separate Operating Instructions)
Troubleshooting
I. The dimmer rack or pack must be capable of using the USITT DMX-512 1990 standard to control
the dimmers. Most modern dimmer racks use this protocol. The system integrator/supplier should
verify compatibility between the WM control unit and the unit(s) to be controlled.
II. 9Volt DC power supply. A 9 volt filtered, unregulated 100mA power source is needed to power
the unit. A remote mounted power supply (PS-1) is included with the Wall Mount™ unit. The BCi
power supply requires 120VAC to power it. Current draw of the power supply is under 1 amp. The
BCi WM-PS1 power supply is enclosed in a galvanized metal box which can be located in a
remote location (electrical room or closet) and has knockouts for ¾” or 1” conduit entry. The
enclosure has a barrier between the 9vdc and 120VAC sections. Conduit should be routed to each
of the two sections separately, one for 120VAC and one for 9vdc runs to the WM.

III. Proper wiring between the components is necessary to assure reliable and trouble free operation of
the system. There are three connections for the unit:
a) 9 volt DC power from the PS-1 to the WM.
b) DMX from the WM to the dimmer(s) or other DMX device(s).
c) 120VAC connection to power the PS-1.
Belden 8471 is an approved wire type for the 9vdc power supply to the WM wiring.
Belden 9729 is the recommended cable type for the DMX-512 data wiring.
a) 9 volt DC – A two position terminal block on the backside of the Wall Mount™ Pocket
Console® is installed for powering the unit. In addition, a 1.3mm power jack is also
available. NOTE: At the WM control station, inserting a 9vdc plug into the 1.3mm input
jack will interrupt the hard-wired 9vdc power connection to the terminal block.
The terminal block is labeled + and – for proper polarity. The 1.3mm jack is center
positive. The “Wall Wart” power supply, which comes with the PS-1, may also be plugged
directly into WM for testing, if this better fits the given application.
Belden 8471 is an approved wire type for the 9vdc power supply to the WM wiring.
b) DMX wiring – A three position terminal block on the Wall Mount™ Pocket Console® is
available for connecting data from the WM to the dimmer rack or DMX device. The
terminals are labeled COM, DATA+ and DATA-. DMX data is a high-speed digital data
protocol and requires special cable for reliable communications between the unit and the
dimmer rack. Cable specifically for RS-485 communications is recommended. Other
cables (alarm cable, RS-232 cable, microphone cable or other multi-conductor cable) are
not recommended.
Belden 9729 is the recommended cable type for the DMX-512 data wiring.
Proper Electrical Grounding is necessary for reliable operation of the system. One of
the most common causes of failure for DMX control devices is improper grounding. A
copper wire connection to ground is recommended. Static electricity can cause havoc in a
microprocessor based control system. Using a copper wire to ground the power supply and
the WM faceplate backbox is the most reliable means of shunting static electricity away
from the electronic components and sending it to ground.
c) 120VAC wiring - This feeds the PS-1 only. It should be a dedicated 120v service capable
of handling a 3amp 120VAC load.
IV.
Using grounded conduit to ground the backboxes is acceptable, but for a truly reliable
ground, copper conductors (wires) are recommended.
Backboxes must be metal to act as a ground.

Programming should be implemented as spelled out in the separate Programming
Instructions. To properly program the unit the following information is necessary:
a) Which dimmers or DMX channels are controlling which fixtures, attributes or lights?
b) Which dimmers or DMX channels you want at FULL when the Panic button is pushed?
c) The Pocket Console® Wall Mount™ has eight faders for controlling the assigned dimmers
or DMX devices. Dimmers are usually grouped as to function (i.e. downlights, sconces,
over table lights, entryway lights, security light, etc.) and then each group assigned to a
fader. The integrator or designer should provide this information.
d) The Panic circuits should allow well lighted egress from the space should an emergency
condition arise.
VI. Troubleshooting. The first step in troubleshooting is to verify that the wiring to the WM and
PS-1 is correct. The attached diagram should be reviewed and the wiring verified. If verification
does not correct the problem, dividing the system into sections will reveal where the problem lies.
If the Pocket Console® Wall Mount™ does not turn on.
If the WM does not turn on (pushing the buttons below the faders does not toggle on and off the
channel LED indicators) then the problem may be in the Power Supply connections.
9VDC power - The Wall Wart power supply, which comes with the Pocket Console® PS-1, can be
plugged directly into the WM faceplate PC board for troubleshooting. If the Wall Mount™ works
with the Wall Wart plugged directly into the faceplate PCB, then the problem is in the wiring
between the PS-1 and the WM. Verify you are getting between 7 and 12 Volts DC at the Pocket
Console® Wall Mount™ PS-1 terminal block.
If the Wall Mount™ Pocket Console® comes on but will not control the dimmers.
If the WM comes on but will not control the dimmers the problem likely lies in the data
connections between the WM and the dimmer rack(s) or other DMX device(s).
Data Wiring – The DMX standard requires that the data line be terminated. What this means is
that the end of the data line (farthest point from the Pocket Console Wall Mount) be terminated
with a 120ohm resistor. Most dimmer racks and DMX devices have a switch, which terminates the
DMX data signal. Only the farthest dimmer rack/DMX device should be terminated. Intermediate
dimmer racks (if more than one dimmer rack/pack is used) should have the termination switches
off. If no termination switch is available, a termination resistor (120 Ohm ¼ Watt or greater)
should be installed between the data+ and data- terminals on the final data destination point.
If this does not correct the problem, move the Pocket Console® Wall Mount™ to the location
where the dimmer rack/DMX device is located. Cut a short length (a few feet) of data cable and
wire the Pocket Console® Wall Mount™ directly to the dimmers. If this corrects the problem, the
problem lies in the data wiring run between the Pocket Console® Wall Mount™ and the dimmers
or DMX device in question.
