CNX Analog/Digital Input/Output
Expansion Card: CNXIO-16

Description

Functional Description

The CNXIO-16 Analog/Digital Input/Output Expansion Card provides 16 analog

inputs or digital input/output connections. All pins pull up to +5V. The digital

output is rated for 250 mA sync from maximum 24 VDC with catch diodes for use

with ‘real world’ loads. The digital input is rated for 0 to 24 VDC. There is a 20K

Ohm input impedance; programmable 2K Ohm pullup resistor (per pin, software

reference to ground or closure to ground). To enable a 0K pull-up resistor, assign a

logic “1” to the corresponding “pu#” pin in the software. The input logic threshold

is 1.25 VDC. Analog input is rated for 0 to 10 VDC, protected to 24 VDC,

maximum.

Physical Description

The CNXIO-16, 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.

5.000 in

(127.00 mm)

0.980 in

The faceplate contains two identical male, 9-pin connectors. There are eight

analog/digital input/output pins and one common ground pin per connector. Silk

screening is applied to the faceplate; pins are labeled A1 through A8 and B1

through B8. Common ground pins are labeled with a C. Two supplied 9-position

connectors can be wired and attached to connectors A and/or B.

Installation

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

Items required to install the CNXIO-16 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 CNXIO-16 contains electrostatic sensitive devices (ESD); observe
precautions for handling ESDs to avoid damaging the card.

NOTE: If installing the CNXIO-16 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 CNXIO-16 with the card guides in the open slot and slide

the expansion card into position.

2 •• CNX Analog/Digital Input/Output Expansion Card: CNXIO-16 Operations Guide - DOC. 8125

4. Firmly press both ends of the CNXIO-16 faceplate to seat the

expansion card into the control system connector.

5. Tighten the thumb screws to secure the CNXIO-16 to the control

system.

6. Reapply power to the CNMSX.

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 CNXIO-16. 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 is familiar with 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 copy
of this program is available from Crestron’s ControlCD (Version 5.1 or later).
Search for the CNXIO-16.SMW project in the SIMPL Windows Example Base.

How the Program Works

A basic CNXMIDI SIMPL program is shown in block diagram form below. For this
example, the CNXIO-16 occupies slot#1 of a CNMSX-PRO. Assume that the
touchpanel is used to control the state of lights1 and lights2 in a typical application.
Input/outputs on the CNXIO-16 (inA1,outA1 through inA8,outA8) in SIMPL
Windows correspond to the CNXIO-16 physical pins A1 through A8. Similarly,
inB1,outB1 through inB8,outB8 corresponds to pins B1 through B8.

How to Create the Program

Configuration Manager

Use the Configuration Manager workspace in SIMPL Windows to select and
configure all the devices that need to be included into the system. For this example,
add a CNXIO-16 to slot #1 of the control system, shown below.

NOTE: SIMPL Windows v1.20.04 or later is required to program the CNMSX­PRO with a CNXIO-16 card. 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 of Crestron’s website
(www.crestron.com). New users are required to register in order to obtain access to
the FTP site.

Programming Manager

Use the Programming Manager workspace in SIMPL Windows to select symbols
and assign their respective signals. For this example, a touchpanel and CNXIO-16
symbols were added automatically when the devices were added to the system in the
Configuration Manager workspace. Expand the Network Module folder and double
click on the touchpanel for a detail view (alternatively CTRL+D or drag and drop
into Detail View). Assign the signals as shown on the next page.

Expand the Central Control Modules folder. Double click on Port 1 to display the
CNXIO-16 in Detail View (alternatively CTRL+D or drag and drop into Detail
View). Assign the signals as shown below.

NOTE: Each port on the CNXIO-16 can be assigned as either an input or output,
but not both. For example, although the software permits the user to assign two
independent signals to i1 and o1, it is improper.

Expand the Logic folder to display the logic symbols used in this program. They
include Analog Compare, Analog Initialize, Multiple One Shots, and OR symbols.
View the symbol in detail view (alternatively CTRL+D or drag and drop into Detail
View). Some logic symbols are shown in optional sub system folders. Assign the
signals as shown below.
