X-CTU Software
X-CTU is a Digi-provided software program used to interface with and configure Digi RF Modules.
The software application is organized into the following four tabs:
• PC Settings tab - Setup PC serial ports for interfacing with an RF module
• Range Test tab - Test the RF module's range and monitor packets sent and received
• Terminal tab - Set and read RF module parameters using AT Commands
• Modem Configuration tab - Set and read RF module parameters
FigureB‐11. X‐CTUUserInterface(PCSettings,RangeTes t,TerminalandModemConfigurationtabs)
NOTE: PC Setting values are visible at the bottom of the Range Test, Terminal and Modem Configura-
tion tabs. A shortcut for editing PC Setting values is available by clicking on any of the values.
Installation
Double-click the "setup_X-CTU.exe" file and follow prompts of the installation screens. This file is
located in the 'software' folder of the Digi CD and also under the 'Downloads' section of the
following web page: www.digi.com/support.
Setup
Serial Communications Software
A terminal program is built into the X-CTU Software. Other terminal programs such as
"HyperTerminal" can also be used to configure modules and monitor communications. When
issuing AT Commands through a terminal program interface, use the following syntax:
FigureB‐12. SyntaxforsendingATCommands
NOTE: To read a parameter value stored in a register, leave the parameter field blank.
The example above issues the DT (Destination Address) command to change destination address
of the module to "0x1F". To save the new value to the module’s non-volatile memory, issue WR
(Write) command after modifying parameters.
To use the X-CTU software, a module assembly (An RF module mounted to an interface Board)
must be connected to a serial port of a PC.
NOTE: Failure to enter AT Command Mode is most commonly due to baud rate mismatch. The
interface data rate and parity settings of the serial port ("PC Settings" tab) must match those of
the module (BD (Baud Rate) and NB (Parity) parameters respectively).
