Description

Functional Description

The CNXAO-8 Analog Output Expansion Card provides eight analog output

connections with a maximum voltage span of +/-12 VDC and 80 mA maximum

source/sink current. The analog output connections are arranged as two groups of

four with a multi-turn span adjustment for each group. Each group has a jumper (X1

and X2) to select whether the outputs power up/reset at 0% or 50%. Furthermore,

each output has a multi-turn offset potentiometer (pot) to position span as required.

Physical Description

The CNXAO-8, shown below, is a circuit board fastened to an aluminum faceplate.

The card is manufactured to easily fit into an unoccupied slot in a Crestron CNX

Generation Control System.

Setup

As of the date of manufacture, the unit has been tested and found to comply with
specifications for CE marking.

NOTE: This card complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) these devices may not cause harmful interference,
and (2) these devices must accept any interference received, including interference
that may cause undesired operation.

Power Up/Reset Voltage Adjustment

The setting of two 3-pin jumpers on the CNXAO-8 card determines whether the
card’s output voltage is equal to the lowest value of the assigned voltage span (0%)
or the midpoint of the voltage span (50%) when the system is powered up or reset.
Two jumpers (X1 and X2) are required to provide adjustment to two output groups
(A and B), respectively.

CAUTION: Besides setting the jumper, initialize values in the SIMPL Windows
program so that the device receiving the analog signal does not exhibit drastic
voltage swings upon start up or reset. Failure to do so may result in damage to the
device being controlled.

2 • CNX Analog Output Expansion Card: CNXAO-8 Operations Guide - DOC. 8142

Installation

Items required to install the CNXAO-8 are already attached to the unit. The only
tools required are a Phillips tip screwdriver and a grounding strap. Follow the
assembly procedure below.

CAUTION: The CNXAO-8 contains electrostatic sensitive devices (ESD); observe
precautions for handling ESDs to avoid damaging the card.

NOTE: If installing the CNXAO-8 into a CNMSX-AV, it is assumed that the
CNXCAGE has been installed.

1. Disconnect power from the CNMSX.

2. Use the Phillips tip screwdriver and remove two screws and blank
faceplate from the control system.

3. Align the CNXAO-8 with the card guides in the open slot and slide the
expansion card into position.

4. Firmly press both ends of the CNXAO-8 faceplate to seat the expansion
card into the control system connector.

5. Tighten the thumb screws to secure the CNXAO-8 to the control
system.

6. Reapply power to the CNMSX.

Output Voltage Limit Adjustment

Once the CNXAO-8 is installed, it is necessary to adjust the lower and upper limits
of the voltage span. To accomplish this adjustment, a voltmeter, small-head slotted

screwdriver, and a procedural program is required. Crestron provides the program
(CNXAO8SU.ZIP) from the Software Downloads page (Examples Library) of our
website (www.crestron.com). This zipped file contains the VisionTools™ Pro (VT
Pro) touchpanel files and a SIMPL™ Windows file (.SMW). These files provide a
simple adjustment program designed to be used to perform the procedures described
in subsequent parapgraphs.

All outputs (A1 through A4 and B1 through B4) are factory set with a 10 volt span of
0 to +10 VDC. If it is necessary to adjust this preset voltage span, be sure that the
CNXAO-8 is installed into the control system and that the VT Pro and SIMPL
Windows procedural programs are running. The first portion of this adjustment
procedure is to set the lower limit (offset). The second portion of the procedure is to
set the upper limit (span). Ths final portion of the procedure is to fine tune the
voltage span.

The first two subsections that follow this paragraph provide the steps necessary to
complete an output voltage limit adjustment. The third subsection is only required if
one desires to minimize the tolerance of the voltage span. As an example, this
procedure sets an output with a 10 volt span that centers around 0 volts (ie., +/-5
VDC).

NOTE: Turn the SPAN and OFFSET pots clockwise (CW) to increase voltage.
Turn pots counter clockwise (CCW) to decrease voltage.

If the need exists, it is possible to
set a different offset voltage for
each output in a group.

Lower Limit Adjustment

This lower limit adjustment procedure sets the low-end voltage value. In general, the
lower limit cannot be less than –12 VDC. This adjustment must be set for each
output utilized in the group.

1. Connect a voltmeter between the A1 output and group A ground.

2. Use the VT Pro program to set the A1 output to its lowest level (0%).

3. Use a screwdriver to adjust the OFFSET A1 pot so that the voltmeter
reads –5 VDC.

4. Repeat “Lower Limit Adjustment” steps 1 through 3 for the remaining
group A outputs (A2, A3, and A4).

Upper Limit Adjustment

This upper limit adjustment procedure sets the high-end voltage value. In general,
the upper limit cannot be more than +12 VDC. This adjustment only needs to be set
for one utilized output in the group.

1. Connect a voltmeter between any group A output (A1 through A4) and
group A ground. For this example, use A1 and ground.

2. Use the VT Pro program to set the A1 output to its highest level
(100%).

3. Use a screwdriver to adjust the SPAN A pot so that the voltmeter reads
+5 VDC.

4. Repeat “Lower Limit Adjustment” steps 1 through 4 and “Upper Limit
Adjustment” steps 1 through 3 to set the adjustment for the group B
outputs. These steps only need to be completed once for each group per
application. Once completed, proceed to the fine tuning portion of the
procedure.

Crestron CNXAO-8 CNX Analog Output Expansion Card

Fine Tune the Voltage Span

Only one utilized output per group needs to be fine tuned to guarantee minimal
tolerance of the voltage span and offset for the CNXAO-8. The procedure below
defines the steps necessary to fine tune one output at a time. For this example, the
procedure fine tunes output A1.

1. Connect a voltmeter between the A1 output and group A ground.

2. Use the VT Pro program to set the A1 output to its midpoint level
(50%).

3. Use a screwdriver to adjust the OFFSET A1 pot so that the voltmeter
reads 0 VDC.

4. Use the VT Pro program to set the A1 output to its highest level
(100%).

5. Use the screwdriver to adjust the SPAN A1 pot so that the voltmeter
reads +5 VDC.

6. Repeat “Fine Tune the Voltage Span” steps 4 and 5 until tolerance is
satisfactorily minimized.

7. Repeat “Fine Tune the Voltage Span” steps 1 through 6 for the
remaining group.

Programming with SIMPL™ Windows

SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all
Crestron system hardware. The objects that are used in SIMPL are called symbols.
SIMPL Windows offers drag and drop functionality in a familiar Windows®
environment.

SIMPL Windows is Crestron Electronics' software for programming Crestron control
systems. It provides a well-designed graphical environment with a number of
workspaces (i.e., windows) in which a programmer can select, configure, program,
test, and monitor a Crestron control system.

The next two subsections describe a sample SIMPL Windows program that utilizes
the CNXAO-8. The first subsection details how the sample program works with a
textual description and block diagram. The second subsection provides a broad
description of how to actually create the SIMPL Windows program.

NOTE: The following description assumes that the reader has knowledge of SIMPL
Windows. If not, please refer to the extensive help information provided with the
software.

NOTE: There is no need to recreate the sample SIMPL Windows program. A
similar copy of this program is available from Crestron’s ControlCD (version 5.2 and
later) or the Software Downloads page (Examples Library) of the Crestron website
(www.crestron.com). Search for the CNXAO8EX.ZIP file. This zipped file contains
the SIMPL Windows file (.SMW) as well as the VT Pro touchpanel files.

How the Program Works

The example SIMPL program is shown below in block diagram form and illustrates
three possible applications of the CNXAO-8. To recreate this example refer to
“Output Voltage Limit Adjustment” on page 3 and follow the procedure to setup port

Operations Guide - DOC. 8142 CNX Analog Output Expansion Card: CNXAO-8 • 5

CNX Analog Output Expansion Card Crestron CNXAO-8

A with a span of 5 volts and an offset equal to 0 volts. Also, refer to “Power
Up/Reset Voltage Adjustment” on page 2 and make sure jumper X1 is set to 0%. If
the jumper is set to 50%, the symbol in the dotted box must be used to initialize
values upon start up or reset.

Block Diagram of System Incorporating a CNXAO-8

The first output, A1, provides a full output range from 0 to 5 volts. As a result, the
user can ramp up or down to any voltage in the five-volt range. The second output,
A2, produces half the range of A1, because the appropriate signal is passed through a
scaler. Thus, the user can only ramp to any voltage between 0 and 2.5 volts. The
third output, A3, provides six distinct output voltages. The appropriate signals passed
through an initializer produce six incremental one-volt outputs that the user selects
with the proper touchpanel button.

How to Create the Program

Configuration Manager

Use the Configuration Manager workspace (Project | Configure System) in SIMPL
Windows to select and configure all the devices that need to be included into the
system. For this example, from the Control Systems folder in the Device Library
select CNMSX-AV with a card cage. Add a CT-3000 from the Touchpanels (Wired)
folder; the touchpanel NET ID must be set to 03, shown below. Drag and drop the
CT-3000 onto Net Device (Slot #8 on the CNMSX-AV).

NOTE: SIMPL Windows v1.30.01 or later is required to program the control
system containing a CNXAO-8. If using an earlier version of SIMPL Windows,
Crestron recommends a SIMPL Windows and operating system upgrade. The latest
version can be obtained from the Software Downloads page (Simplwin Library) of
