XStream-PKG-E™ Ethernet RF Modem – Product Manual v4.2A

RF Modem Configuration

Out-of-box, the XStream-PKG-E Ethernet RF Modem comes configured to provide an immediate

wireless link between devices in a data system. The default configuration supports a wide range

of RF communications. The RF modem is configurable to support specific system requirements

using standard AT Commands.

For more advanced configuration information, refer to:

• “XStream Advanced Programming & Configuration” manual (for AT Command Mode

Options, Diagnostics, Networking, Serial Interfacing and Sleep Modes)

• “XPort User Manual (for advanced configurations specific to the Ethernet port)

Both manuals are located in the “documentation” folder of the MaxStream CD.

AT Command Mode

In order to set or modify RF Modem parameters, the RF Modem must first enter into “AT

Command Mode”, a state in which incoming characters are interpreted as AT commands instead

of data to be transmitted.

Enter AT Command Mode

To enter AT Command Mode, use any of the following methods:

1. Send the 3-character command sequence “+++” with one second of silence before and

after the command characters. [See the “Default AT Command Mode Sequence” below.]

The “Terminal” tab (or other serial communications software) of the X-CTU Software can be

used to enter the sequence.

2. Press-in the Config Switch [Figure 2c] while turning off and then on again the Power Switch

[Figure 1a].

Default AT Command Mode Sequence (for entering into AT Command Mode):

1. No characters sent for one second.

[Time can be modified using BT (Guard Time Before) Command]

2. Input three (3) plus characters (“+++”) within one second.

[Character can be modified using CC (Command Sequence Character) Command.]

3. No characters sent for one second.

[Time can be modified using the AT (Guard Time After) Command.]

NOTE: Binary Commands do not work with the Ethernet RF Modem because

cannot be controlled

over Ethernet. Refer to the “Advanced Programming & Configuration” manual for more information.
