Ewave Stamper User’s Manual V1.0 1 Introduction Ewave's STAMPER™ RF Data Modem is a member of Ewave’s family of application specific data radios. It is an intelligent wireless link optimized for wireless programming and debugging of the Parallax BASIC Stamp (PBASIC) processor. This product is a true "dropin" replacement for a serial cable. The STAMPER allows wireless real-time debugging or monitoring of your PBASIC code.
Ewave Stamper User’s Manual V1.0 2 Overview The picture at right shows a pair of STAMPER radio modems as they would be connected in a typical BASIC Stamp system. The cable in the lower-right corner goes to the PC’s Comm. port. The STAMPER’s high performance design employs a matched pair of transceivers for true “full-duplex” operation, which means each radio modem allows simultaneous transmission of data on one radio frequency while receiving data on a second radio frequency offset by 25MHz.

For best performance, position the STAMPERs such that their antennae are parallel to each other and perpendicular to the Earth.
Ewave Stamper User’s Manual V1.0 4 Troubleshooting For the most up-to-date Troubleshooting information, please visit Ewave’s On-line Support Center at http://www.electrowave.com/support/ NOTE: When troubleshooting a new problem, it is useful to understand the three general types of failures of your BASIC Stamp system. The three general categories are: 1. 2. 3. Problems having nothing to do with the Ewave STAMPER.

Ewave Stamper User’s Manual V1.0 6 Using the STAMPER as a General Purpose Data Link 6.1 Introduction It is extremely easy to use the STAMPER modems to send serial data wirelessly between a BASIC Stamp and any other serial device such as a PC, another BASIC Stamp, or any other device with a serial port. The STAMPERS are designed to look like a wired connection to your application. They provide a bydirectional full duplex wireless link. When first powered-up the STAMPERs automatically establish a radio link.
Ewave Stamper User’s Manual V1.0 In the sections which follow, please refer to the pin-out diagram below of the STAMPER modem’s DB9 connector. The pin-out and pin-functions are identical on both the “Base” and “Mobile” versions of the STAMPER modem. 6.4 Electrical Connection between BASIC Stamp and PC This section describes how to electrically connect the STAMPER modem to the BASIC Stamp’s generalpurpose I/O pins to allow use of PBASIC’s SERIN and SEROUT commands for serial data transfers.
Ewave Stamper User’s Manual V1.0 For example, if you are using the BASIC Stamp II, this BASIC statement: Serout 1,16468,[“HELLO”] uses Pin 1 of the STAMP II at 9600 baud to send the “HELLO” text. A complete description of the SEROUT and SERIN commands can be found in the Parallax documentation, including a discussion of interfacing the Parallax PBASIC products to devices operating at standard RS232 voltage levels. 10 Copyright © 2001 by Ewave, Inc.
Ewave Stamper User’s Manual V1.0 7 Using The Configurator The Configurator is a software utility available from Ewave’s web site (http://www.electrowave.com/downloads/) which automates several configuration operations with Ewave Radio Modems. The Configurator can also act as a simple terminal-emulator with ASCII or hexadecimal display modes, which is useful for experimenting with and debugging serial devices. 7.
Ewave Stamper User’s Manual V1.0 7.2 Using the Configurator as a Simple Terminal Emulator The Configurator can also be used as a simple terminal emulator for debugging and experimenting with serial peripherals. In this mode, it allows you to display received data in hexadecimal or as plain text. It also allows you to enter arbitrary characters in hexadecimal by typing “\nn” where nn are the two hex. characters.
