(Type A to mini-B)

• Use PanelPilot software, to setup and customize the display

• Compatible with Windows XP, 2000, Vista and Windows 7

• Over 40 meter templates to choose from

• New templates automatically download in PanelPilot software

• Programmable via the USB interface

The OM-SGD-35-M is a smart graphics display

with a 320 x 240 pixel (QVGA) color display and USB programming interface.

Using the PanelPilot software (available for Windows XP, 2000, Vista and 7),

users are able to choose from an ever-increasing number of congurations (six voltmeters at launch)

which can then be customized to their needs.

OM-SGD-35-M

OM-CABLE-USB-A-MF

Colors, text labels, splash screen and input voltage scaling can all be customized by the user through the software and then uploaded to

the OM-SGD-35-M through the USB connection.

Panel or enclosure installation of the display is simple, using a panel xing clip to mount the display, and 4 screw terminals to connect

the inputs.

Voltage Input

The OM-SGD-35-M features 2 voltage inputs, which use a Programmable Gain Amplier (PGA) to make the best use of available resolution

(the smallest voltage range offers the highest resolution). Each channel can be programmed independently, with the option of eight different

input voltage ranges:

Voltage Range (V)

0 - 1.25

0 - 2.5

0 - 4 0 - 5

0 - 8

0 - 10

0 - 20

0 - 40

Note: V+, IN1 and IN2 share a common ground (i.e. not oating or isolated from each other).

Resolution (mV)

The input voltage range is decided using the two voltages that the user enters in the scaling section of the Panel Pilot software. The software uses the smallest range available, which can accommodate both of the voltages entered by the user. The

absolute maximum voltage input is 40V d.c.

For example:

Entering a voltage scale of 0 – 30V in the software will use the 0 – 40V range. Entering a voltage scale of 0 – 3V in the software will use the 0 – 4V range. Entering a voltage scale of 5 – 15V in the software will use the 0 – 20V range.

USB connection

A ‘Type A to Mini-B’ USB cable is required to program and customize the OM-SGD-35-M. It typically takes 10 seconds to send a conguration,

with an additional 5 seconds needed for the hardware to reset.

The OM-SGD-35-M can be powered directly from USB and is compatible with both USB 1.1 and USB 2.0. The screw terminals and advanced

connector can remain connected whilst using USB, but it is not necessary for V+ to be powered.

Smart Graphics Display

Display

The display is a 3.5” TFT panel, with a resolution of 320 x 240 pixels and a 16-bit color depth. Any graphics that are uploaded to the

meter are automatically converted to this specication. A resistive touchscreen is tted, for use with supporting applications. Clean the

screen with a damp, soft, lint free cloth.

Panel Mounting

The OM-SGD-35-M can be tted into panels 1mm - 3mm deep.

A silicone seal is included to improve tting on thin panels.

Panel cut-out is 92mm x 74mm.

NOTE: The display is NOT protected against moisture or dust.

provision for future expansion using data buses (SPI and I2C) and

alarm ouputs. Some expansion options may require an additional

interface board - Visit www.omega.com for information on which

features are currently supported.

PANELPILOT SOFTWARE

Omega’s PanelPilot software is available for download free of charge from www.omega.com. Easy to install and use, the control software

runs under Windows 2000, XP, Vista and 7. The software is used to setup the appearance and operation of the meter and then upload these

settings to the meter.

The software allows the following parameters to be congured:

• Meter type

• Text labels (including units and graph labels)

• Background, graph segment and text colors

• Input scaling / calibration (at two points)

• Decimal points (entered during scaling)

• Splashscreen image selection (to display a user image, such as a logo, when the meter is powered up)
