Chapter 7 Remote Communications
7.1. Installing USB Drivers
Prior to running the command-line interface, the USB drivers must be installed. To
install the drivers the user must have administrative rights on the computer,
also depending on the operating system used you may need to right click on the
“CD-Starter2.exe” application located on the CD and choose the “Run as
Administrator” menu option. The MDT693B and MDT694B must not be
connected to the PC while installing the drivers. Insert the CD that was
supplied with your unit into your PC. From the dialog box that is displayed, select
the Install Drivers button. If the dialog box is not displayed, browse to the CD in
Windows and run CD_Started.exe. Follow the onscreen prompts to install the
driver. After the driver is installed, attach the MDT693B or MDT694B to the PC and
power it on. Your PC will then detect the new hardware and will prompt you when
the installation is complete.
7.2. Command-Line Interface
Once the USB drivers have been installed, the unit connected to the PC, and the
power turned on, configure the terminal emulator as follows:
Baud Rate = 115.2 kb/s
Data Bits = 8
Parity = None
Stop Bits = 1
Flow Control = None
If the connection is correct you will see the following after pressing the “Enter” key.

The basic structure of the interface is a keyword followed by either an equals sign
“=” or a question mark “?”. The “=” or “?” will determine if the string is a command
or a query. All strings (commands and queries) must be terminated by a carriage
return (CR) or a line feed (LF) or any combination of a carriage return and a line
feed or pressing the ENTER key on the computer.
The command structure is as follows:
Keyword = argument (Command Terminator)
Where “keyword” defines the function and “argument” is a numerical value followed
by any valid command terminator. A valid command terminator is a carriage return
(CR), a line feed (LF) or any combination of a carriage return and line feed. See
listing below.
The query structure is a follows:
Keyword? (Command Terminator)
The “keyword” defines the function and the question mark (?) indicates a query.
The query is terminated by any valid command terminator. A valid command
