Introducing the OM-LGR-5329

This user's guide contain s all of the information you ne ed to connect the OM-LGR-5329 to your computer and to the signals you want to measure and log.
®
The OM-LGR-5329 is a USB 2.0 full-speed device supported under popular Microsoft systems. The OM-LGR-5329 is compatible with both USB 1.1 and USB 2.0 ports.
With a multiplexed 16-bit A/D converter and a maximum sampling rate of 200 kS/s for all analog i nput channels, the OM-LGR-5329 can sample:
Up to 16 single-ended analog inputs Up to eight differential analog inputs In ranges of ±30 V, ±10 V, ±5 V, ±1 V
You can start an analog input scan by:
Windows® operating
Pressing the Configuri ng an external digital trigger Configuri ng an external analo g trigger Configuri ng a multichannel analog trigger Configuri ng a digital pattern trigger Pressing the
The OM-LGR-5329 also has 16 isolated digital input connections (PLC thresho lds with 28 V tolerance) that you can configure to detect and log events based on change of state or pattern recognition. The device provides 500 V of isolation between the digital inputs and the host P C , analog input s, and counter inputs.
The OM-LGR-5329's single digital output is a 500 V alarm output implemented as a single Form C relay. You can configure the relay to energize when the trigger condition is met and data is being recorded.
The OM-LGR-5329's four counter channels support the following counter modes:
Counter (general event counting) Period counting Pulse width c ounting Edge-to-edge timing 1X, 2X, and 4X encoder counting. Up/down counting
You can use the Modulo N number and mode with all of the counter modes listed to determine how the counter behaves when it reaches the modulo number you set.
You can configure each counter channel in encoder mode for single-ended or differential mode using an external switch.
START button
TRIG button to manually override a configured trigger
The device saves data to and retrieves data from a Secure Digital (SD) or Secure Digital High Capacity (SDHC) memory card. The OM-LGR-5329 requires 9–30 V of external power.

OM-LGR-5329 User's Guide Getting Started with the OM-LGR-5329

Installing the software

Refer to the DAQLog Software User’s Guide for instructions on installing and using the DAQLog software. This guide i s available in PDF at
www.omega.com/manuals/.

Installing the hardware

Follow these steps to provide power to the OM-LGR-5329 and connect it to a USB port on your host computer.

Providing power to the OM-LGR-5329

To power the OM-LGR-5329 from its screw terminals, connect the PWR+ terminal to the positive lead of
your power source, and the that meets the power specifications of the OM-LGR-5329.
To power the OM-LGR-5329 from an external power source, using the power connector , connect the 9 V,
1 A external power supply to the external power into an electrical outlet.
Always provide power to the OM-LGR-5329 before connecting its USB cable to the computer
Connect the external power cable to the OM-LGR-5329 before connecting the USB cable to the computer. Thi s allows the OM-LGR-5329 to inform the host computer (when the USB cable is connected) that the device requires minimal power from the computer’s USB port.
PWR- terminal to the negative lead of the power source. Use a power source
connector (see Figure 3 on page 10), and plug the adapter

Connecting the OM-LGR-5329 to your system

To connect t he OM-LGR-5329 to your system, turn the computer on, and connect a USB cable fro m the OM­LGR-5329's USB connector (see Figure 3 on page 10) to either a USB port on the computer or an external USB hub connected to the computer.
When you connect the OM-LGR-5329 for the first time, a is detected. When the message clo ses, the installation is complete.
