4.2. Programming Examples
4.2.1. AT Commands
PC Settings Tab (X-CTU Software)
Terminal Tab (X-CTU Software)
Refer to the ‘Command Mode’ section [p20] for information regarding entrance into Command
Mode, sending AT commands and exiting Command Mode.
MaxStream has provided X-CTU software for programming the modem using an extensive list of
AT Commands. The X-CTU software provides an interface that is divided into four tabs that facili-
tate the following functions:
To install the X-CTU Software:
As stated in the Serial Communications section [p12]; in order to communicate data to the RF
modem through the PC, the baud (serial data rate), data bit, parity and stop bit settings on the PC
serial port must match those of the modem. The 'PC Settings' tab provides a software user inter-
face that facilitates the modification of PC serial port setting.
PC Setup
Figure 4‐02. Setup for RF Modem Configurations through X‐CTU Software
A terminal program has been built into the X-CTU software and is located under the 'Terminal' tab.
The Terminal tab provides an easy-to-use interface for programming the modem.
Multiple AT Commands. Multiple AT commands can be entered on one line with one carriage
return at the end of the line. Each command must be delimited by a comma (spaces in between
are optional). The "AT" prefix is only sent before the first command and should not be included
with subsequent commands in a line.
System Response. When a command is sent to the modem, the modem will parse and execute
the command. Upon successful execution of a command, the modem returns an "OK" message. If
execution of a command results in an error, the modem returns an "ERROR" message.
