 Microsoft Bluetooth stack Broadcom® Bluetooth stack (not supported by Windows XP SP3)
InstaCal™ is required to install, configure, and test the BTH-1208LS on
Windows platforms.
Measurement Computing recommends that you connect one of thedigital grounds (GND) to earth ground to reduce the chance of theBTH-1208LS unexpectedly powering down due to electrostaticdischarge.

BTH-1208LS Quick Start

Install the MCC DAQ Software
The MCC DAQ CD can be installed on Windows platforms. The
Universal Library for Android is included in the InstaCal & Universal
Library installation.
Note: To develop on Linux® or Mac® platforms, download andinstall the Universal Library for Android fromwww.mccdaq.com/ULforAndroid.
Refer to the Quick Start that ships with your device for instructions on
installing the other software available on the MCC DAQ CD.
Select Android Examples to install example projects on Windowsplatforms to deploy and run on an Android device.

Refer to the UL for Android Example Projects help topic in the UL for
Android help files to learn how to deploy and run example projects onan Android device.
Extract the Universal Library for Android help files from the default

BTH-1208LS Quick Start

Pairing with the Host Device
Pairing creates a bond between a Bluetooth device and a host device. A
host device can be either a Windows-based computer or an Androiddevice (tablet, phone, or mini-PC).
The BTH-1208LS must be paired with the host device before it canestablish a wireless connection and transmit acquired data to the device.
A BTH-1208LS only has to be paired once with the same host device.
The BTH-1208LS can be paired or connected when powered bybatteries (standard or rechargeable) or by an external USB power
supply.
The BTH-1208LS cannot be paired when powered by a USB hostdevice.
To pair the BTH-1208LS as a Bluetooth device, make sure the device is
not connected to a USB host, and complete the following steps:
1. Make sure the host device is configured to host a Bluetooth device.

Refer to host device documentation to learn how to enable Bluetoothand how to search for and pair with Bluetooth devices.
2. If powered by batteries, press and hold the button for at least fiveseconds to power on the device and put it into pairing mode.
If powered by a USB power supply, press and hold the button for atleast three seconds to put it into pairing mode.
When the Power and Status LEDs blink alternately, the device is inpairing mode and is ready to pair with the host device.
3. Select the Bluetooth device setup in the host device OS software, andthen select the BTH-1208LS when it displays. Refer to the Bluetooth
documentation of your host device to learn how to pair it with aBluetooth device.

3BTH-1208LS Quick Start

For example, in Windows, select Bluetooth Device from theControl Panel, and then double-click on BTH-1208LS-xxxx in theAdd a device dialog box (xxxx are the last four digits of the device
serial number). You may need to wait a few seconds for the device todisplay.
If the host device requests a passkey, PIN or pairing code, enter thedefault value for the device (0000).
4. Press and hold the power/pairing button for two seconds to remove

the device from pairing mode.

Checking the Bluetooth Connection
Once the BTH-1208LS is paired to the host device, run an applicationthat communicates with the device.

 For Windows PCs, launch InstaCal.
 For Android devices, launch a UL for Android example project (referto the UL for Android Example Projects help topic to learn how todeploy and run Android example projects). The default installation
directory for the Universal Library for Android help is Program
Files\Measurement
Computing\DAQ\Android\ul_help.zip

The Status LED turns on to indicate a Bluetooth connection isestablished.
