1.2. Product Overview

When networked with other MaxStream Radio Modems (RS-232/485, Ethernet, USB, etc.), the

XStream PKG Telephone Modem provides a transparent wireless link between serial devices and

telephone modems. The telephone interface extends MaxStream’s over-the-air range with the

reach of any PSTN (Public Switched Telephone Network).

The XStream-PKG-T RF Modem comes configured to provide an immediate wireless link between

devices; however, both the on-board RF and Telephone Modules can be configured for additional

functionality through the use of a simple AT command interface [Refer to the RF Module

Configuration [p15] & Telephone Module Configuration [p20] sections for programming options].

LED indicators visualize diagnostic status information.

The RF Modem’s status is represented as follows:

Yellow (top LED)= Serial Data Out (to host)

Green (middle) = Serial Data In (from host)

Red (bottom) = Power/TX Indicator

(Red light is on when powered,

off briefly during RF transmission)

Used to determine RSSI (Received Signal Strength Indicator)

and fade margin available in the wireless link:

3 Green LEDs ON = Very Strong (> 30 dB fade margin)

2 Green LEDs ON = Strong (> 20 dB fade margin)

1 Green LED ON = Moderate (> 10 dB fade margin)

0 Green LED ON = Weak (< 10 dB fade margin)

Fade Margin = The difference between the incoming signal

strength and the modem’s receiver sensitivity.

Illuminated yellow LED indicates telephone

connection is established and (Data Carrier

Detect) is asserted.

This signal is controlled by the Telephone

Module.

The PKG-T RF Modem provides a wireless link between devices out-of-box and without

configuration. If more advanced features are needed, the XStream RF Module and Telephone

Module can be configured via the DB-9 connector or a wireless link.

The Data Path Switch is controlled by the and lines of the DB-9 connector. In the PKG-

T’s RF Modem’s default state (when nothing is attached to the DB-9 connector), data is routed

between the RF module and the telephone module. In this case, the Telephone Module

communicates directly with a remote RF Modem and receives commands through a wireless link.

2. RFModuleOperation

2.1. Modes of Operation

An on-board RF module enables the XStream-PKG-T RF Modem to send and receive data over-

the-air. The RF module operates in five modes.

Figure2‐01. RFModule’sModesofOperation

Themodemcanonlybeinonemodeatatime.

2.1.1. Idle Mode

When not receiving or transmitting data, the module is in Idle Mode. The module uses the same

amount of power in Idle Mode as it does in Receive Mode.

The modem shifts into the other modes of operation under the following conditions:

•Serial data is received in the DI Buffer (Transmit Mode)

•Valid RF data is received through the antenna (Receive Mode)

•Command Mode Sequence is issued (Command Mode)

•Sleep Mode condition is met (Sleep Mode)

After responding to any of the preceding conditions, the modem automatically transitions back

into Idle Mode.

2.1.2. Transmit Mode

When the first byte of serial data is received from the UART in the DI buffer, the modem

attempts to shift to Transmit Mode and initiate an RF connection with other modems.

communications cha

Channel initialization is the

process of sending an RF

initializer that synchronize

receiving modems with the

transmitting modem. When

streaming multiple RF packet

the RF Initializer is only sent in

front of the first packet.

During channel initializati

incoming serial data

accumulates in the DI

After the channel is initialized,

data in the DI buffer is

grouped into packets (u

bytes in each packet) and is transmitted. The modem continues to transmit data packets until th

DI buffer is empty. Once transmission is finished, the modem returns to Idle Mode. This

progression is shown above.

As the transmitting modem nears the end of the transmission, it inspects the DI buffer to see if

more data exists to be transmitted. This could be the case if more bytes arrived from the host

after the transmission began. If more data is pending, the transmitting modem assembles a

subsequent packet for transmission.

RF Packet

The RF packet is the sequence of data used for communicating information between MaxStream

Modems. An RF Packet consists of an RF Initializer and RF Data.

RF Initializer

An RF initializer is sent each time a new connection sequence begins. The RF initializer contains

channel information that notifies receiving modems of information such as the hopping pattern

used by the transmitting modem. The first transmission always sends an RF initializer.

An RF initializer can be of various lengths depending on the amount of time determined to be

required to prepare a receiving modem. For example, a wake-up initializer is a type of RF

initializer used to wake remote modems from Sleep Mode (Refer to the FH, LH, HT and SM

Commands for more information). The length of the wake-up initializer should be longer than the

length of time remote modems are in cyclic sleep.
