Description
Functional Description
There are two Crestron RS-232/422/485 COM module configurations available:
ST-COM and STI-COM. All of the features are identical with the exception of input
power requirements and unit nomenclature. The ST-COM uses a power pack rated
for 120 VAC supply and the STI-COM uses a power pack rated for 220 VAC. Use of
the power packs are optional within a Cresnet system. For purposes of this
Operations Guide, the term ST-COM is used for either configuration, except where
noted.
The ST-COM is a device with two independent bidirectional serial ports that can
support RS-232, RS-485, or asynchronous RS-422-based communication. The unit
enables a system to overcome the distance limitations of serial communication. It can
be used as part of the Cresnet system or SmarTouch STS to add control for
additional serial devices such as video projectors or AV switchers. If part of the
Cresnet system, use of the power pack is optional.
Both ports of the ST-COM may be used to control a wide variety of RS-232,
RS-485, or asynchronous RS-422 controlled equipment. A variety of
communications parameters are supported. Valid parameters are as follows.
Operations Guide - DOC. 5695A

Baud rates may be one of the following possible rates: 300, 1200,
1800, 2400, 3600, 4800, 6100, 7200, 9600, 14400, 19200, 28800,
38400, 57600, and 115200. When specifying the baud rate on a port, do
not use commas.
•
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 ST-COM. If both are enabled, RTS/CTS is
used. If CTS handshaking is enabled, the CTS line is monitored by the
ST-COM. 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 statement is generated for as long as the signal is held high.
•
Provides character pacing in units of milliseconds for all of the data
specified. The range of the pacing is from 1 to 31 milliseconds. Pacing
greater than 31 milliseconds defaults to the maximum (31 ms).
•
Supports RS-485. However, additional drivers are required and specific
protocol must be followed. The unit remains in receive mode until
transmission is enabled with one character switching. Consult
Crestron’s award winning customer service team in your area.

ST-COM Ports
A number of ports are provided on the back of the ST-COM. Each has a silkscreened label. Refer to illustration and descriptions below.
ST-COM Ports
12 VDC .5A
This direct current (DC) power socket connector is used to supply power via the
external power pack, when attached. If the power pack is used while 24 VDC is
present on the NET connector, the power pack supplies power to the unit (no current
is drawn from the network).
Crestron recommends specific power packs for its devices. The acceptable power
pack for the ST-COM is Crestron part number PW-1205 (PWI-1210 for the
international version, STI-COM). If a power pack other than this Crestron model is
obtained, verify that it meets the required specifications and polarity as shown
below.

NET
These two 6-pin, 6-position RJ11 modular jacks are used to connect the ST-COM
module to either the SmarTouch STS or Cresnet remote control system. When the
module is part of the Cresnet system, power is provided via the NET connection; the
power pack need not be attached. Two NET ports are available so that network units
can be daisy-chained together. Review the latest revision of the Network Modular
Cable Requirements (Doc. 5682).
NOTE: Most 4-conductor phone cables are wired in a crisscross fashion and are not
compatible with Crestron equipment.
NOTE: The ST-CP does not supply network power. Therefore, use the power pack
to supply power to the ST-COM.
If a power pack is attached when the module is part of the Cresnet system, power is
drawn from the power pack. The module does not load the network power, but the
network remains chained for additional network devices that are connected.

ST-COM Indicators
There are 10 LED indicators located on the front panel of the ST-COM. Refer to
illustration below and descriptions that follow.
ST-COM Indicators
PWR (Power)
This LED illuminates when 12 volts (from power pack) or 24 volts DC (from
network) is supplied to the ST-COM.
NET
This LED illuminates when communication between the ST-COM and either the
SmarTouch STS or Cresnet system is established. Illumination indicates that the
SIMPL program currently loaded has a network device defined at the same NET ID
as the ST-COM.
RXD (COM A / B)
These LEDs flash when the ST-COM receives data from the serial device attached to
the respective COM ports.
TXD (COM A / B)
These LEDs flash when the ST-COM transmits data to the serial device attached to
the respective COM ports.
RTS (COM A / B)
If RTS/CTS handshaking is enabled, these LEDs illuminate when the ST-COM is
ready to receive transmission of data from a serial device attached to the respective
COM ports.
CTS (COM A / B)
These LEDs illuminate when the serial device on the respective COM port is ready
to accept transmission of data from the ST-COM. This “Clear to Send” signal is
available only if RTS/CTS handshaking is enabled; signal is controlled by external
serial device. If CTS signal is not connected (in cable), the signal is held high and the
LEDs are extinguished.

Setup
Identity Code
Every equipment and user interface within the network requires a unique identity
code (NET ID). These codes are recognized by a two-digit hexadecimal number
from 03 to FE. The NET ID of each unit must match an ID code specified in the
SIMPL Windows program. The NET ID of each ST-COM has been factory set to 20.
The NET IDs of multiple ST-COMs must all be unique and changed from a personal
computer (PC) via SIMPL Windows or VisionTools™ Pro-e (VT Pro-e).
NOTE: VT Pro-e is a Windows compatible software package for creating Crestron
touchpanel screen designs.
The method for changing the unit's NET ID is identical regardless of the software
chosen. Complete the following steps to change the NET ID.
1.
Attach one of the ST-COMs to the control system (verify that the
software is running).
2.
From the SIMPL Windows or VT Pro-e menu, select Tools | Viewport
to open the Crestron Viewport.
3.

software checks the baud rate and then opens the "Set Network ID"
window.
4.
In the "Set Network ID" window, select the ST-COM from the Current
Network Devices text window.
5.
From the Choose the new network ID for the selected device (Hex): text
box, select the new NET ID for the ST-COM.
6.
Click Set ID to initiate the change. This will display the "ID command
has been sent" window.
7.
In the "Command Complete" window, click OK.

Programming with SIMPL Windows
SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programing 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's 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 nest two sections describe a ST-COM within SIMPL Windows. The first section
provides initial configuration information, the second section reviews the inputs and
outputs of the ST-COM symbol, and the third section provides the location of
example programs.
NOTE: The following descriptions assume that the reader has knowledge of SIMPL
Windows. If not, refer to the extensive help information provided with the software.

Example Program
An example program can be obtained from the Downloads page (EXAMPLES
Library) of the Crestron website (www.crestron.com). Search for ST-COM.SMW.
New users are required to register in order to obtain access to the FTP site.
This example program illustrates serial control of Zone 1 in a lighting system. The
lighting system communicates with port A of the ST-COM over RS-422 with 38400
N81 settings. Zone 1 can either be turned ON or OFF or can be ramped UP or down.
This example program is designed expecting that the only serial input for Zone 1 are
those in the COM port definition of the ST-COM.
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). If rx$ is defined, it can be
routed to other string processing symbols (i.e. Serial 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 help topics from the Help pull-down menu in
SIMPL Windows. Search for Analog to Serial or Serial Gather for details.

No merchandise may be returned for credit, exchange, or service without prior authorization

and request an RMA (Return Merchandise Authorization) number. Enclose a note specifying
the nature of the problem, name and phone number of contact person, RMA number, and
return address.
2.
Products may be returned for credit, exchange, or service with a CRESTRON Return
Merchandise Authorization (RMA) number. Authorized returns must be shipped freight
prepaid to CRESTRON, Cresskill, N.J., or its authorized subsidiaries, with RMA number
clearly marked on the outside of all cartons. Shipments arriving freight collect or without an
RMA number shall be subject to refusal. CRESTRON reserves the right in its sole and
absolute discretion to charge a 15% restocking fee, plus shipping costs, on any products
returned with an RMA.
3.
Return freight charges following repair of items under warranty shall be paid by CRESTRON,
shipping by standard ground carrier. In the event repairs are found to be non-warranty, return
freight costs shall be paid by the purchaser.
CRESTRON Limited Warranty
CRESTRON ELECTRONICS, Inc. warrants its products to be free from manufacturing defects in
materials and workmanship under normal use for a period of three (3) years from the date of

rotating mechanical parts, pan/tilt heads and power supplies are covered for a period of one (1)
year; touchscreen display and overlay components are covered for 90 days; batteries and
incandescent lamps are not covered.
This warranty extends to products purchased directly from CRESTRON or an authorized
CRESTRON dealer. Purchasers should inquire of the dealer regarding the nature and extent of the
dealer's warranty, if any.
CRESTRON shall not be liable to honor the terms of this warranty if the product has been used in
any application other than that for which it was intended, or if it has been subjected to misuse,
accidental damage, modification, or improper installation procedures. Furthermore, this warranty
does not cover any product that has had the serial number altered, defaced, or removed.
This warranty shall be the sole and exclusive remedy to the original purchaser. In no event shall
CRESTRON be liable for incidental or consequential damages of any kind (property or economic
damages inclusive) arising from the sale or use of this equipment. CRESTRON is not liable for
any claim made by a third party or made by the purchaser for a third party.
CRESTRON shall, at its option, repair or replace any product found defective, without charge for
parts or labor. Repaired or replaced equipment and parts supplied under this warranty shall be
covered only by the unexpired portion of the warranty.
Except as expressly set forth in this warranty, CRESTRON makes no other warranties, expressed
or implied, nor authorizes any other party to offer any other party to offer any warranty, including
any implied warranties of merchantability or fitness for a particular purpose. Any implied
warranties that may be imposed by law are limited to the terms of this limited warranty. This
