CONNECTIONS/CABLE SPECIFICATIONS
LMI offers a variety of software and hardware solutions to collect data or even multiplex the Diamondback
Series indicators. Contact LMI to provide you with the most efficient solution.
There are three methods that can be used for transferring data from the unit to a base unit, such as a PC. The
methods for transferring data are USB using the LMI 6026 cable, Digimatic using the LMI 6028 cable and
RS232 using the LMI 6027 cable.
Note that the cables are not included, but may be purchased from LMI Corporation. In order to communicate
using a USB cable the PC requires a driver to be installed. The drivers may be installed from the CD-ROM
that was included or on the LMI’s web site

CONNECTIONS
USB
USB is a virtual COM-Interface. Drivers will be required for the digital indicator to communicate to the PC.
To install the drivers, insert the CD-ROM that came with the digital indicator. Click on the Install Drivers tab
and click on Install Drivers again. Once the drivers are loaded, the digital indicator will be able to
communicate via USB. The drivers will emulate a virtual COM-Port for every indicator that is connected to
the PC. The application software communicates to the instrument in exactly the same manner as a normal
hardware COM-port.
The default baud rate for using a USB connection through a virtual com port is 57600 bits per second. You
can change the baud rate to 9600 bits per second by pressing and holding the SEND button for 5 seconds.
The LCD screen will highlight all the characters indicating that the baud rate has been changed. The baud
rate will remain changed even after the unit is powered off. Press and hold the SEND button again until the
LCD highlights to change the baud rate back to 57600.
Data format: [Reading] followed by Carriage Return i.e. 5.00 {CR}
COM Settings: Baud Rate 57600, parity: none, stop bit: 1, and data bits: 8
Press and Hold (5 seconds) the SEND button to switch the baud rate to 9600 bps
