OM-SGD-43-A
4.3” Smart Graphics Display
OM-SGD-43-A is a 4.3” capacitive touch display designed for use with
PanelPilotACE Design Studio, a free drag-and-drop style software package
for rapid development of advanced user interfaces
and panel meters.
The OM-SGD-43-A is the rst in a range of PanelPilotACE compable displays and panel meters. The low-prole display
features a 4.3” capacive touch screen and an ARM Cortex A9 processor running embedded Linux. The display can be
powered from either USB or a 5 to 30V d.c. supply and oers users a wealth of hardware interfaces which include four
16bit bi-polar analogue inputs (to a maximum of ±40V d.c.), eight digital input/output pins, two alarm outputs (maximum
current sink 10mA) and four 8bit PWM outputs.
Users program the display using the free PanelPilotACE Design Studio soware which allows the creaon of anything from
simple meters and dials, through to advanced user interfaces with control elements.

PanelPilotACE Design Studio
Making Industrial User Interface Design Simple
The design soware provides a number of building blocks which allow users to drag-and-drop elements onto the screen
to quickly create advanced user interfaces. From background images to text elements, analogue style meters, touch
screen navigaon elements and even complex logic statements, users can build up mul-screen interfaces without
needing to write a line of code.
There is a library of pre-dened elements such as meters, buons and switches, and users can create their own content
by combining elements or imporng graphics in a number of formats (including jpg, png, f, bmp and gif). The soware
includes support for transparency and mulple layers.
Hardware interfacing is similarly intuive, with hardware elements being dragged into a funcon builder where
associaons with graphical elements (such as a needle on a meter) can be dened. Here users can determine scaling for
analogue inputs, dene alarm triggers, behaviours for digital inputs and outputs and congure PWM outputs.
Previewing and Uploading Projects
The soware includes a ‘Preview in Emulator’ funcon which emulates the hardware’s inputs and outputs, allowing users
to test their projects prior to upload. Projects are uploaded to the OM-SGD-43-A via a mini USB port.
PanelPilotACE Design Studio is compatible with Windows XP (SP3), Vista, 7 and 8 and can be downloaded free
from www.omega.com.

To minimise osets it is best pracce to connect analogue grounds directly to
the meter pins (PL11) or screw terminals (TBLK1).
The OM-SGD-43-A uses a programmable gain amplier (PGA) together
with a 16-bit analogue to digital converter (ADC) for its analogue voltage
measurements. The PGA is automacally set when the analogue range of a
channel is input into the PanelPilotACE Design Studio.

Scaling: The sense resistors used are 110Ω. Therefore in soware scaling 4mA equates to 0.44V and 20mA equates to
2.2V.
Note: transmier terminals (+ or -) must be isolated from the power supply
Driving an Alarm Output
The alarm outputs are open-collector. When an alarm is acve, the output can sink up to 10mA.
