About This Manual This manual is intended for use by service technicians responsible for installing and working with the MaxStream™ XStream-PKG wireless modem. 1.0 Authorized distributors and their employees can view or download this manual from the Rice Lake Weighing Systems distributor site at www.rlws.com.
2.0 Installation This section describes procedures for connecting the MaxStream XStream-PKG wireless modem to a host device. Immediately after unpacking, visually inspect the modem to ensure that all components are included and undamaged. The shipping carton contains the modem, power supply, cabling, and this manual. The MaxStream XStream-PKG wireless modem connects to a host device using a 9 pin RS-232 D-Sub connector. This connection supplies serial communications hookup.
3.0 Operation There are various operating states associated with the operation of the MaxStream XStream-PKG wireless modem. The following sections describe the stages of operation. 3.1 Standby When the radio is not transmitting or receiving, it is in standby mode and ready to receive data. From standby, the radio can either transmit, if data is presented on the serial port; or receive, if data is presented over the air.
4.0 MaxStream Commands The MaxStream XStream-PKG is available with advanced power-down and addressing options. These options can be configured through either of the two command modes, binary, or AT commands. By default, all data received on the RX pin is transmitted on the RF channel. The command modes differentiate commands from the data and allow various operating parameters to be changed.
4.2.1 Entering AT Command Mode Commands and data are both sent to the same serial UART on the MaxStream modem. A special break sequence must be sent to get the modem into AT command mode. After the sequence all subsequent characters are interpreted as commands and are sent as data. The default sequence for command mode is: 1. No characters sent for one second (before command character time, change with ATBT). 2. Send three plus characters “+++” (command entry character, change with ATCC). 3.
AT Binary Command Command # WR 8 Description Write all configurable parameters to non-volatile memory. All setable parameters are stored.
4.3 Low Power Modes The MaxStream XStream-PKG wireless modem has several low power modes that enable it to be used in low power or battery operated environments. While in low power mode, it is only able to check for whatever stimulus will return the modem to power up mode. No transmitting or receiving can occur.
5.0 Networking with the XStream The MaxStream XStream-PKG wireless modem is built around a peer-to-peer protocol that inherently supports a multi-drop type network (similar to RS-485). In their default state, any XStream modem will communicate with any other XStream modem in its default state. When one modem transmits, all other modems within range will tune into the transmission and output the data received out of the serial port.
