9XTend‐PKG‐R RS‐232/485 RF Modem – Product Manual v1.2.44. Modem Configuration4.1. Automatic DIP Switch ConfigurationsEach time an RF Modem is powered on, AT commands are sent to the on-board RF module asdictated by the positions of the DIP switches. DIP switch configurations are sent automaticallyduring the power-on sequence and affect modem parameter values as shown in the table below.Figure 4‐01. DIP SwitchesTable 4‐01.

When switches 5 and 6 are ON, only the CScommand is sent [refer to table below].Table 4‐02.

9XTend‐PKG‐R RS‐232/485 RF Modem – Product Manual v1.2.44.2. Programming ExamplesFor information about entering and exiting AT and Binary Command Modes, refer to theCommand Mode section [p18].4.2.1. AT Commands (Using X-CTU Software)MaxStream has provided X-CTU software for programming the modem using an extensive list ofAT Commands. The X-CTU software provides an interface that is divided into four tabs thatfacilitate the following functions:• PC Settings tab - Setup PC serial port to interface with an XTend RF Modem• Range Test tab – Test XTend RF Modem's range in varying environments• Terminal tab – Configure and read XTend RF Modem parameters using AT Commands• Modem Configuration tab – Configure and read RF Modem parametersTo install the X-CTU Software:Double-click the ‘setup_X-CTU.exe’ file that is located on the MaxStream CD and under the‘Downloads’ section of the following web page: www.maxstream.net/helpdesk/. Then follow theprompts of the installation screens.PC Settings tabAs stated in the Serial Communications section [p12]; in order to communicate data to the RFmodem through the PC, baud (serial data rate), data bit, parity and stop bit settings on the PCserial port must match those of the RF modem. The ‘PC Settings’ tab provides a software userinterface that facilitates the modification of PC serial port setting.PC Setup1. Set the DIP Switch to RS-232 mode. Switch 1 is ON (up) and the remaining 5 switches areOFF (down).2. Connect the male DB-9 connector of the PC with the female DB-9 connector of the RFmodem using an RS-232 cable.3. Power the RF modem through the power connector.4. Go to the PC Settings tab and select parameter values from the dropdown lists that matchthe current parameter values of the RF modem.Figure 4‐02. Setup for RF Modem Configurations through X‐CTU SoftwareTerminal tabA 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 carriagereturn at the end of the line. Each command must be delimited by a comma (spaces in betweenare optional). The “AT” prefix is only sent before the first command and should not be includedwith subsequent commands in a line.System Response. When a command is sent to the modem, the modem will parse and executethe command. Upon successful execution of a command, the modem returns an “OK” message. Ifexecution of a command results in an error, the modem returns an “ERROR” message.© 2005 MaxStream, Inc. Confidential and Proprietary 21
