Crestron ST-PC Dual AC Power Control Module
Dual AC Power Control Module:
ST-PC
Introduction
Features and Functions
There are two Crestron®Dual AC Power Control Module configurations available:
ST-PC and STI-PC. Configuration is based on the type of power availability. Use the
ST-PC with a 120V power supply and the STI-PC with a 220V power supply. For
purposes of this Operations Guide, the term ST-PC is used for either configuration,
except where noted.
The ST-PC is a dual power controller that switches AC power on and off at two
independent AC sockets mounted on the unit. Each socket is tied to a relay that is
able to support a combined load (sockets A and B) of 10 Amp, maximum (6 Amp,
maximum, for the STI-PC). There are several unique features of the ST-PC.
• Two momentary pushbutton switches on the front panel of the unit can be
programmed to toggle the relays via the control system.
• The pushbutton switches locally toggle a relay when the control system is
inactive.
• During network activity, the relays assume the state dictated by the control
system.
Functional Summary
The ST-PC is used as part of a Cresnet®control system. Use of the supplied power
pack is optional.
NOTE: When connected to both the Cresnet power and the external power supply,
the Cresnet power is disconnected.
• Two momemtary pushbuttons to toggle the relays
• Two network connectors for daisy-chaining units
• Rack mountable with optional ST-RMK (1 space height)

ST-PC 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-PC symbol in
the SIMPL Windows’ Programming Manager.
ST-PC SIMPL Windows Symbol
The ST-PC provides two discrete AC sockets. The <pwr> inputs supply power to a
device for as long as the input is high; when a <pwr> input goes low AC power to
the device is turned off.
The <press> outputs go high whenever the corresponding push button on the ST-PC
is pressed.
Device Extenders
To facilitate network functions and diagnostics, SIMPL Windows provides two
device extenders for the ST-PC.
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.
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-PC in Program View, point to Insert
Device Extender and select the desired device extender. To program a device
extender, expand the ST-PC 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
12 •Dual AC Power Control Module: ST-PC Operations Guide – DOC. 5708A

Crestron ST-PC Dual AC Power Control Module
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-PC is not field upgradable.
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) of the
respective Operations Guide for the control system. These documents are available
from the Downloads | Product Manuals section of the Crestron website
(www.crestron.com). Refer to the following figure for a typical connection diagram
when uploading files.
NOTE: Use a standard DB9 male to female “straight-through” cable.
