InfoWave Radio Modem Configuration

From MobileRobots Research and Academic Customer Support

This document describes how to reconfigure your Innomedia InfoWave radio modem if necessary. Reconfiguration is only necessary if for some reason its programming has been lost.

Note that communication via radio modems has been mostly replaced by the use of Lantronix WiBox ethernet-serial bridge device to carry communications over wireless ethernet networks rather than analog radios; the instructions on this page apply only to the InfoWave analog radio modems.

First of all, do NOT run the Infowave software on your modem, if you do the modems will no longer work. Below is described the proper way to set them up, if you find you need to.

Note: Saphira 6.1e or earlier will not work properly with your Pioneer through the InfoWave modems. All later versions, and all versions of ARIA will work with InfoWave modems.

Although we don't recommend it, you may alter the settings for your InfoWave modems, according to the technical specifications given at the manufacturer's site, http://www.innomedia.com/wavescript.html . The pages contain a complete Command Set.

The following describes the process we use to set up the modems for use.

Directly connect with a modem through a serial port on your basestation computer, running Hyperterminal, Kermit, minicom, or other simple serial terminal program. Settings are 9600 baud, 8 data bits, No parity, 1 stop bit. Use hardware handshaking, and turn echo on. All commands begin with WM. For example, WML lists the current settings. The following is a list of commands to type to set the modems up. The settings for the robot modem and the basestation modem are slightly different.

Pioneer-          Basestation-      Meaning
mounted           modem           
-------------------------------------------------------------------
wml               wml               List current settings 
wmb5              wmb5              Sets default baud rate to 9600
wmf128            wmf128            Set data frame to 128 bytes
wmjNAME           wmjNAME_host      Personalizes the name on the modems
wmm2              wmm1              Set modem address, 1 = host, 2 = robot
wmiDDDDDD         wmiDDDDDD         Modem id, 6 hex digits, needs to be
                                    the same for both modems, each pair
				    of modems should have its own number
wml               wml               Check the settings match above

There is also a "PN" (pair number) which needs to be the same for the modem pair, different for each group of pairs. To change this, use WMP# where # is exactly 32 hexadecimal characters long and identical for each modem in a pair. The following is a list of some numbers which work particularly well. This number controls the way in which the modem does frequency hopping.
