Crestron C2COM-2/3 2-Series RS-232/422/485 Expansion Cards

2-Series RS-232/422/485

Expansion Cards: C2COM-2/3

Introduction

Functions and Features

The C2COM-2 and C2COM-3 RS-232/422/485 expansion cards provide RS-232,

RS-422, or RS-485 serial communication for a Crestron®2-Series control system

(PRO2, RACK2, PAC2, or AV2 with cage card). The C2COM-2 has two serial ports

while the C2COM-3 has three serial ports. The C2COM-2/3 fits in any of the 2-

Series control system’s Y-bus slots. The Y-bus provides high-speed communications

and supports current and enhanced Crestron control system expansion cards. All

C2COM-2/3 ports can communicate with the Crestron Network Poll Accelerator.

NOTE: The Network Poll Accelerator allows a 2-Series control system to maintain a

fast response time (high-speed communication) between the control system and a

large number of Cresnet®devices. For more information, refer to the latest revision

of the Network Poll Accelerator Operations Guide (Doc. 6087).

The C2COM-2/3 supports baud rates up to 115,200 bps (and higher with the

Network Poll Accelerator), and a variety of communication parameters with

hardware and software handshaking. Valid parameters are shown in the functional

summary.

Functional Summary

• Supports RS-232, RS-422, and RS-485 communications via DB9 male

connector

• Baud rates: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600 and

115200

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

• Data bits may be 7 or 8

• Stop bits may be 1 or 2

• Both XON/XOFF software handshaking and RTS/CTS hardware handshaking

are supported

• Break sequence can be generated under program control

NOTE: Due to a non-standard pin configuration that allows the C2COM-2/3 to

support RS-232, RS-422, and RS-485, Data Set Ready (DSR) and Data Terminal

Ready (DTR) are not supported.

Physical Description

The C2COM-2/3 is a circuit board fastened to an aluminum faceplate. The card is

manufactured to easily fit in an unoccupied Y-bus slot of a Crestron 2-Series control

system. The faceplate on the C2COM-2 contains two identical bidirectional DB9

male connectors while the C2COM-3 contains three bidirectional DB9 male

connectors. The connectors are labeled A, B and C. Refer to the following

illustrations for a detailed view.

Industry Compliance

As of the date of manufacture, the C2COM-2 and C2COM-3 have been tested and

found to comply with specifications for CE marking and standards per EMC and

Radiocommunications Compliance Labelling (N11785).

NOTE: This device complies with part 15 of the FCC rules. Operation is subject to

the following two conditions: (1) this device may not cause harmful interference,

and (2) this device must accept any interference received, including interference that

may cause undesired operation.

Installation and Hookup

The C2COM-2/3 cards are designed for installation into a dedicated expansion slot

on a 2-Series control system.

CAUTION: The C2COM-2/3 and control system contain electro-static discharge

(ESD) sensitive devices. Perform the following procedure while wearing a

2-Series RS-232/422/485 Expansion Cards Crestron C2COM-2/3

grounding strap that is properly grounded and on a grounded workstation to avoid

damaging the C2COM-2/3 and/or the control system.

CAUTION: To prevent stripping of screw heads, threads, or mounting holes, DO

NOT overtighten screws. Tighten only to the specification listed in the individual

step(s).

NOTE: If the C2COM-2/3 is being installed in an AV2, the optional CAGE2 must

be installed before continuing below. For instructions on installing the CAGE2 into

an AV2 control system, refer to the latest revision of the CAGE2 3-Card Expansion

Cage for AV2 Installation Guide (Doc. 5964).

Installation

Follow the instructions below to install the C2COM-2/3 into a 2-Series control

system.

Tools/hardware required

Non-standard DB9 (RS-232/422/485) cable (Refer to DB9 cable

information on page 5)

Phillips screwdriver

Grounding strap or grounded workstation

1. Disconnect power from the control system.

2. Remove the two screws and blank faceplate from the desired slot in the

control system using a Phillips screwdriver.

3. Align the C2COM-2/3 with the card guides in the open slot and slide

the expansion card into the slot.

4. Firmly press both ends of the C2COM-2/3 faceplate to seat the

expansion card in the control system connector.

5. Hand-tighten the thumbscrews to secure the C2COM-2/3 to the control

system.

6. Connect DB cable(s).

7. Reapply power to the contol system.

Hookup

Non-standard DB9 connectors (two on the C2COM-2, three on the C2COM-3)

provide distinct bidirectional serial ports on the C2COM-2/3. Refer to the following

sample hookup illustration.

NOTE: For pinout information on connection to third-party serial devices,

download Crestron’s Cable Database Software. The latest version can be obtained

from the Downloads | Software Updates section of the Crestron website

(www.crestron.com).

Sample Hookup Connections for C2COM-2 (top) and C2COM-3 (bottom)

Serial Device

NOTE: The pinout of each 9-pin port is non-standard. Therefore, do not use a

straight-through DB9 cable. The following table contains pinout descriptions for

RS-232 and 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.

Non-Standard COM Pinout (for RS-232 and RS-422 Communication)

PIN DIRECTION DESCRIPTION

1* To C2COM-2/3 (RXD-) RS-422 Receive Data (Idles low)

2 To C2COM-2/3 (RXD) RS-232 Receive Data

3 From C2COM-2/3 (TXD) RS-232 Transmit Data

4 From C2COM-2/3 (TXD+) RS-422 Transmit Data (Idles high)

5 Ground RS-232 and RS-422 Signal Common

6 To C2COM-2/3 (RXD+) RS-422 Receive Data (Idles high)

7 From C2COM-2/3 (RTS) RS-232 Request to Send

8 To C2COM-2/3 (CTS) RS-232 Clear to Send

9 From C2COM-2/3 (TXD-) RS-422 Transmit Data (Idles low)

*RS-422 transmit and receive are balanced signals requiring two lines plus a ground in each direction. RXD+

and TXD+ should idle high (going low at start of data transmission). RXD- and TXD- should idle low (going

high at start of data transmission). If necessary, RXD+/RXD- and TXD+/TXD- may be swapped to maintain

correct signal levels.

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

communicate with a PC, as shown in the following diagram. Since the pinouts on the

C2COM-2/3 are 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.

Important Information for PRO2 Users

When power is applied to the PRO2, the front panel displays the Main Menu (shown

below). The COM menu function button (directly below COM) allows the user to

monitor transmission and reception traffic on every COM-type device and card that

is active in the SIMPL Windows program loaded in the control system, including the

C2COM-2/3.

PRO2 Front Panel (Sample of Main Menu)

When the COM button is pressed, (default front panel page) the display shows a list

of devices and cards to be monitored (one at a time). The user selects the slot and

port for the C2COM-2/3 by using the NEXT or PREV buttons on the panel. For

more information on viewing port traffic, refer to latest revision of the PRO2: 2-

Series Integrated Dual Bus Control System Operations Guide (Doc. 5957). It is

available from the Downloads | Product Manuals section of the Crestron website

(www.crestron.com).
