Page 4: Introduction
6" one-half wave dipole antenna Note: To comply with the FCC RF exposure requirements, the MaxStream XStream-PKG can only be used with approved antennas that have been tested with this modem and a minimum separation distance of 20 cm Figure 1-1. MaxStream XStream-PKG Modem (8") must be maintained from the antenna to any nearby... -
Page 5: Installation
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. The power supply plugs into a round pin 7-18VDC plug. -
Page 6: Operation
Transmitting The MaxStream modem leaves standby mode when data is received by the serial port which then sends incoming data through the air. Once in transmit mode, the modem starts to send buffered data. Data is sent in packets up to 64 bytes long. -
Page 7: Maxstream Commands
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. -
Page 8: Entering At Command Mode
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. - Page 9 20 (0x14) will allow any radio to transmit within the next 2 seconds utilizing a beacon of 8ms instead of 35ms. Use this parameter to speed up communication latency and turn-around time. Table 4-1. MaxStream Command Table (Continued) MaxStream XStream-PKG Wireless Modem Operation Manual...

Page 10: Low Power Modes
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. -
Page 11: Networking With The Xstream
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. -
