CNX RS-232/422/485 Expansion

Card: CNXCOM-2

Description

Functional Description

The CNXCOM-2 RS-232/422/485 Expansion Card provides RS-232, RS-422, or

RS-485 communication with hardware and software handshaking. Speeds are rated

up to 38,400 bps. In fact, a variety of communication parameters are support. Valid

parameters are as follows.

•Baud rates may be one of the following possible rates: 300, 600, 1200,

2400, 4800, 9600, 19200, and 38400.

•Parity may be even, odd, none, or zero stick (parity bit always 0).

When specifying the parity use E, O, N, or Z, respectively.

•Data bits may be 7 or 8.

•Stop bits may be 1 or 2.

•Both XON/XOFF handshaking and RTS/CTS handshaking are

supported. XON/XOFF handshaking may be supported by specifying

XON (for both transmit and receive), XONR (for receive only), or

XONT (for transmit only). XON/XOFF and RTS/CTS handshaking

are mutually exclusive in the CNXCOM-2. If both are enabled,

RTS/CTS is used. If CTS handshaking is enabled, the CTS line is

monitored by the CNXCOM-2. The CTS line can also be enabled as a

digital input to the control system; the RTS line can be enabled as a

digital output.

•Specify RS422 for standard if RS-422 compatible levels must be

supported.

•Break character of any length can be generated.

•Supports RS-485. However, a specific protocol for defining the

mechanism as to when a device is permitted to transmit on the RS-485

bus must be followed. To use this feature, use RS-422 communications

settings. Set hardware handshaking to none. The RTS output can now

be used to enable the transmitter. Notice that the receiver is always

active. Therefore, transmissions are also received.

NOTE: The pinout of each 9-pin port is non-standard, therefore use of a straight-

through cable is not appropriate. The table following this note contains pinout

descriptions for RS-232 as well as RS-422. Conflicts with some equipment may

occur unless the controlled devices are properly wired. Certain devices have specific

voltage requirements. Therefore, do not use all nine pins in a given application.

Although the possibility is remote, improper wiring may result in damage to the

controlled device. Only the required pins for each communication type should be

connected.

A common application is to use a three-wire null modem serial cable to

communicate with a PC, shown below. Since the pinout on the CNXCOM-2 is non-

standard, the card should not be plugged into the PC directly. The pinout in this

illustration emulates the IBM PC AT connector except for the RS-422 signals on

pins 1, 4, 6, and 9.

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 CNXCOM-2. 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 CNXCOM-2.SMW project in the SIMPL Windows Example Base.

Operations Guide - DOC. 8123 CNX RS-232/422/485 Expansion Card: CNXCOM-2 •• 5

How the Program Works

A basic CNXCOM-2 SIMPL program is shown on the next page in block diagram

form. For this example, the CNXCOM-2 occupies slot #1 of a CNMSX-PRO.

Assume that a touchpanel is used to control the state of Zone 1 in a lighting system.

Zone 1 can either be turned ON or OFF or can be ramped UP or DOWN.

Block Diagram of CNXCOM-2

To turn the lights on, 9 bytes are sent (\x02Z-01-ON\x03). When join #1 on the

touchpanel is pressed, the signal "Lights-Z1-On" goes high. When this signal goes

high, the data is sent out the port to the lighting system. A similar approach is taken

for "Lights-Z1-Off". These buttons have true feedback from the lighting system

(i.e., when the 16 bytes (\x02Z-01-STATUS-ON\x03) enter the port, the digital

signal "Lights-Z1-On-F" goes high and drives the feedback of join #1 high). In turn,

this lights the feedback for the OFF button on the panel.

In order to ramp the zone, the appropriate command is sent to start the ramping

operation when the UP or DOWN button is pressed. When either button is released,

the output of the NOR gate goes high. This, in turn, sends the STOP command to

the lighting system, telling it to halt the ramping operation in progress.

It is important to note that the user does not have to define the [TX$] or [RX$] for

the port. If strings are being triggered and matched only in the port, the string

assignment is taken care of by the compiler. If the TX$ is defined, it can be driven

by other string creation symbols (i.e., an Analog to Serial or speed key: TXA). If

RX$ is defined, it can be routed to other string processing symbols (i.e. Serial

Gather or speed key: GATHER). Another typical usage would be if a macro were to

drive the port, then the TX$ and RX$ would come from/go to the macro definition.

Refer to the help file in SIMPL Windows. From the Contents search on Symbol

Card File or from the Index search on the names of the symbols for details.

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 CNXCOM-2 to slot #1 of the CNMSX-PRO. Also add a CT-3500 to the

system; its NET ID must be set to 03, shown on the next page.

NOTE: SIMPL Windows v1.20.04 or later is required to program the CNMSX-

PRO with a CNXCOM-2 card. If using an earlier version of SIMPL Windows,

Crestron recommends a SIMPL Windows and operating system upgrade. The latest

CRESTRON

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.

Graphical System View of CNXCOM-2 and CT-3500 in SIMPL Windows’ Configuration

Manager

The lighting system communicates with port A of the CNXCOM-2 over RS-422

with 38400 N81 settings. These preferences for the port are set up in the

Configuration Manager. Click on the CNXCOM-2 in slot #1 of the CNMSX-PRO

to display the ports of the card in the Detail System View area of the Configuration

Manager. To assign the forementioned settings, double click on the white field in

port A. The “Device Settings” dialog box opens. Confirm the parameters, shown

below.

“Device Settings” Dialog Box

Use the Programming Manager workspace in SIMPL Windows to select symbols

and assign their respective signals. For this example, a touchpanel and CNXCOM-2

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 after this paragraph.
