Crestron ST-CS Current Sensor Module
Current Sensor Module: ST-CS
Introduction
Features and Functions
There are two Crestron®Current Sensor Module configurations available: ST-CS
and STI-CS. Configuration is based on the type of power availability. Use the ST-CS
with a 120V power supply for 120 VAC devices, and the STI-CS with a 220V
power supply for 220 VAC devices. For purposes of this Operations Guide, the term
ST-CS is used for either configuration, except where noted.
The ST-CS measures the average current of each half cycle of an AC load. The
current sensing circuitry is highly sensitive with a wide range of adjustment. The
high sensitivity makes the ST-CS ideally suited for use with low power units as
VCRs, TV tuners, and satellite receivers. The wide range makes the ST-CS ideally
suited for medium and high-powered units such as TV sets, video projectors, and
power amplifiers up to 10 A total load (6 A for STI-CS).
When the ST-CS electronic circuit senses that the average current drawn by a
monitored unit exceeds the FULL LOAD preset threshold, the full load LED
(labeled FULL) illuminates. The ST-CS sends a signal to the control system
indicating the current ST-CS status.
Secondary circuitry senses and determines whether the average current is less than
the FULL LOAD preset, but more than no load. This PARTIAL LOAD threshold is
also adjustable. The FULL LOAD and PARTIAL LOAD circuitry is mutually
exclusive; only one definite status is communicated to the control system. The FULL
and PARTIAL LEDs are illuminated one at a time.
Threshold adjustments are accomplished by use of a 15-turn precision potentiometer
(POT). The POT permits highly accurate and repeatable current threshold settings.
Functional Summary
• Ideally suited for use with large TVs (minimum load specification
0.033A, 4W).
• The wide range makes the ST-CS ideally suited for medium and high-
powered units such as TV sets, video projectors, and power amplifiers.
• Rack mountable with optional ST-RMK (1 space height).

Setup
Identity Code
Refer to the note on page 14 for a
definition of Viewport.
All equipment and user interfaces within the network require a unique identity code
(Net ID). These codes are two-digit hexadecimal numbers from 03 to FE. The Net
ID of each unit must match an ID code specified in the SIMPL Windows program.
Refer to “Setting the Net ID in Device Settings” on page 12 for details of the SIMPL
Windows procedure.
The Net ID of the ST-CS has been factory set to 18, The Net IDs of multiple ST-CSs
in the same system must be unique. Net IDs are changed from a personal computer
(PC) via the Crestron Viewport.
NOTE: For detailed information on establishing communication between the PC
and control system, refer to “Communication Settings” on page 14. If
communication cannot be established, refer to the “Troubleshooting
Communications” section in the respective Operations Guide for the control system.

Crestron ST-CS Current Sensor Module
Earliest Version Software Requirements for the PC
NOTE: Crestron recommends that you use the latest software to take advantage of
the most recently released features. The latest software is available from the
Downloads | Software Updates section of the Crestron website (www.crestron.com).
The following are the earliest useable software version requirements for the PC:
• SIMPL Windows, any version. Requires SIMPL+ Cross Compiler version
1.1.
• Crestron Database, any version. Required by SIMPL Windows.
• Crestron Viewport version 3.35 or later.
Programming with SIMPL Windows
NOTE: The following assumes that the reader has knowledge of SIMPL Windows.
If not, refer to the extensive help information provided with the software.
NOTE: The following are file extensions for programs that include an ST-CS,
developed for specific control system types:
.smw source file
.spz compiled file for 2-series
.bin compiled file for CNX generation
.csz compiled file for CNX generation with SIMPL+
.ush compiled file for CNX generation with SIMPL+ header file
.usp source code module for SIMPL+
.umc user macro for SIMPL
NOTE: In the following description, the PRO2 control system is used.
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. SIMPL Windows offers drag and drop
functionality in a familiar Windows®environment.
This section describes a sample SIMPL Windows program that includes an ST-CS.
Configuration Manager is where programmers “build” a Crestron control system by
selecting hardware from the Device Library. In Configuration manager, drag the
PRO2 from the Control Systems folder of the Device Library and drop it in the upper
pane of the System Views. The PRO2 with its associated communication ports is
displayed in the System Views upper pane.
PRO2 System Views
Operations Guide – DOC. 5677A Current Sensor Module: ST-CS •11

Current Sensor Module Crestron ST-CS
The System Views lower pane displays the PRO2 system tree (refer to the following
graphic). This tree can be expanded to display and configure the communication
ports.
Expanded PRO2 System Tree
C2Net-Device Slot in Configuration Manager
To incorporate an ST-CS into the system, drag the ST-CS from the Cresnet Control
Modules | Cresnet I/O Control & Other Modules folder of the Device Library and
drop it in System Views. The PRO2 system tree displays the ST-CS in Slot 9, with a
default Net ID of 18 as shown in the following illustration.
NOTE: The first ST-CS in a system is preset with a Net ID of 18 when its symbol is
dragged into the upper pane of System Views. Additional ST-CS units are assigned
different Net ID numbers as they are added.
C2Net Device, Slot 9
Setting the Net ID in Device Settings
Double-click the ST-CS icon to open the “Device Settings” window. This window
displays the ST-CS device information. If necessary, select the Net ID tab to change
the Net ID as shown in the following figure.
12 •Current Sensor Module: ST-CS Operations Guide - DOC. 5677A

Crestron ST-CS Current Sensor Module
ST-CS “Device Settings” Window
NOTE: SIMPL Windows automatically changes the Net ID values of a device
added to a program if a duplicate device or a device with the same default Net ID
already exists in the program. Always ensure that the hardware and software settings
of the Net ID match. For Net ID hardware setting details, refer to “Identity Code” on
page 7.
ST-CS Symbol in Programming Manager
Programming Manager is where programmers “program” a Crestron control system
by assigning signals to symbols. The following graphic shows the ST-CS symbol in
the SIMPL Windows’ Programming Manager.
ST-CS SIMPL Windows Symbol
The ST-CS incorporates two independent current sensors in one unit. The <Full
Sense> outputs go high whenever the average current drawn by a monitored device
exceeds the upper threshold that is specified for that device.
The <Partial Sense> outputs go high when the current drawn by the device exceeds
an intermediate threshold.
Device Extenders
To facilitate network functions and diagnostics, SIMPL Windows provides two
device extenders for the ST-CS.
The Poll Manager and The Poll Manager (2 Series Extended) symbols are device
extenders for plug-in control cards and for Cresnet devices and touchpanels. The
Poll Manager takes the device on and offline without need to physically disconnect it
from the network, and reports the current connection status of the device.
Operations Guide – DOC. 5677A Current Sensor Module: ST-CS •13

Current Sensor Module Crestron ST-CS
The device extenders are available with X-Series and 2-Series control systems; they
are not available with the ST-CP or CN-Series control systems.
To add a device extender, right-click the ST-CS in Program View, point to Insert
Device Extender and select the desired device extender. To program a device
extender, expand the ST-CS in Program View and drag the device extender to Detail
View.
Uploading
Assuming a PC is properly connected to the entire system, Crestron programming
software allows the programmer to upload programs and projects after their
development to the system and network devices. However, there are times when the
files for the program and projects are compiled and not uploaded. Instead, compiled
files may be distributed from programmers to installers, from Crestron to dealers,
etc. In those instances, one has the option to upload via the programming software
or to upload via the Crestron Viewport.
NOTE: The Crestron Viewport is available as a pull-down command from SIMPL
Windows and VT Pro-e (Tools | Viewport) or as a standalone utility. The Viewport
utility performs multiple system tasks, primarily via an RS-232 or TCP/IP
connection between the control system and a PC. It is used to observe system
processes, upload new operating systems and firmware, change system and network
parameters, and communicate with network device consoles and touchpanels, among
many other tasks. Viewport can function as a terminal emulator for generic file
transfer. All of these functions are accessed through the commands and options
inViewport menus. Therefore, for its effectivness as a support and diagnostic tool,
the Crestron Viewport may be preferred over development tools when uploading
programs and projects.
NOTE: Firmware for the ST-CS is not upgradable in the field.
The following section defines how to upload a SIMPL Windows program. Before
attempting to upload, it is necessary to establish communications.
Communication Settings
NOTE: For laptops and other PCs without a built-in RS-232 port, Crestron
recommends the use of PCMCIA cards, rather than USB-to-serial adapters. If a
USB-to-serial adapter must be used, Crestron has tested the following devices with
good results:
Belkin (large model) F5U103
I/O Gear GUC232A
Keyspan USA-19QW
Other models, even from the same manufacturer, may not yield the same results.
The procedure in this section provides details for RS-232 communication between
the PC and the control system. If TCP/IP communication is preferred, consult the
latest version of the Crestron e-Control Reference Guide (Doc. 6052) or the
respective Operations Guide for the control system. These documents are available
