CNX Infrared & Serial Expansion
Card: CNXIR-8

Description

Functional Description

The CNXIR-8 Infrared & Serial Expansion Card provides for infrared (IR), ASCII,

or other serial communication and control. IR output is rated up to 1.12 MHz.

Serial protocols include RS-232.

NOTE: RS-232 levels provide a 0 – 5V range, which may not be compatible with

all devices.

Physical Description

The CNXIR-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.

CNXIR-8 Faceplate

The faceplate contains one male, 16-pin connector. Silk screening is applied to the

faceplate; pins are labeled A through H. A supplied 16-position connector can be

wired and attached to the faceplate connector.

Setup

Installation

Items required to install the CNXIR-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 CNXIR-8 contains electrostatic sensitive devices (ESD); observe
precautions for handling ESDs to avoid damaging the card.

NOTE: If installing the CNXIR-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 CNXIR-8 with the card guides in the open slot and slide the

expansion card into postion.

4. Firmly press both ends of the CNXIR-8 faceplate to seat the expansion

card into the control system connector.

5. Tighten the thumb-nail screws to secure the CNXIR-8 to the control

system.

6. Reapply power to the CNMSX.

Preparation for Use

Connections are made to the eight serial outputs for IR, one-way RS-232, or serial

interface. Each output is labeled S (signal) and G (ground). Refer to a sample

hookup diagram below and aside from reapplying power to the control system last,

complete theconnections in any order.

NOTE:

DEVICE

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 CNXIR-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 copy

of this program is available from Crestron’s ControlCD (version 4.03 and later).

Search for the CNXIR-8.SMW project in the SIMPL Windows Example Base.

How the Program Works

A basic CNXIR-8 SIMPL program is shown below in block diagram form. For this
example, the CNXIR-8 occupies slot #1 of a CNMSX-PRO. Assume a touchpanel
interfaces directly with two IR drivers. Port A contains a Sony ST-92TV IR driver
and Port C contains a Panasonic AG-1980 VCR IR driver. Both drivers are obtained
from the Crestron Database. The touchpanel directly activates buttons on the IR
drivers, which closely simulates a user pressing buttons on the remote. As long as a
button is held on a touchpanel, the IR command tied to that button is sent out.

Block Diagram of CNXIR-8

How to Create the Program

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 CNXIR-8 to slot #1 of the CNMSX-PRO. Also add a CT-3000 to the system;
its NET ID must be set to 03, shown on the next page.

NOTE: SIMPL Windows v1.19.08 or later is required to program the CNMSX­PRO. If using an earlier version of SIMPL Windows, Crestron recommends a
SIMPL Windows and operating system upgrade.

Graphical System View of CNXIR-8 and CT-3000 in SIMPL Windows’ Configuration

Manager

Click on the CNXIR-8 in slot #1 of the CNMSX-PRO to display all the IR ports of

the card in the Detail System View area of the Configuration Manager. To assign

specific IR devices, select them from either the Crestron or User Database which is

available from the Device Library. Both are sorted by manufacturer or device type.

For this example, a Sony ST-92TV driver is assigned to Port A and a Panasonic

AG-1980 VCR driver is assigned to Port C, as shown below. Both were selected

from the Crestron Database.

NOTE: The two drivers selected have built-in logic. Configuration Manager

displays a Default Logic Window when the driver is dropped its respective port. To

maintain simplicity of the example, default logic was not loaded for each of the

devices.

CNXIR-8 Port Assignments Displayed in the Detail System View Area of SIMPL

Windows’ Configuration Manager

Use the Programming Manager workspace in SIMPL Windows to select symbols

and assign their respective signals. For this example, a touchpanel and CNXIR-8

symbols were added automatically when the devices were added to the system in the

Configuration Manager workspace. Expand the Network Modules folder and double

click on the touchpanel for a detail view (alternatively CTRL+D or drag and drop

into Detail View). Assign signals as shown on the next page.
