Product Description

The CreataLink2 XT device is a two-way data transceiver that supports the ReFLEX protocol. The CreataLink2 XT device can initiate transmissions into a ReFLEX Narrow Band Personal Communications System (NBPCS) network, re ceive and decode data, and store it. It can forward messages it receives from the ReFLEX network to an interconnected hos t device via an RS-232 level or TransistorTransistor Logic (TTL) level serial port. The CreataLink2 XT device performs all necessary ReFLEX protocol processing to maintain connection to the ReFLEX network, accurately receives and acknowledges messages, and delivers messages in conformance with protocol requirements.

The CreataLink2 XT provides an 8-bit, bi-directional parallel Input/Output (I/O) port. Each bit can be configured individually as an input or output by the integrator or end-user. The product also has two Analog-to-D igital (A/D) input ports for customer use.

An additional pin is provi ded for a secondary battery so urce. This secondary source can be used to back-up RAM contents in the event of a power failure and can be selected through software to power the transmitter.

The CreataLink2 XT device can support an off-board application configuration (see Figure 2-1 below). Off-board applications communicate with the CreataLink2 XT using the Communications Linking Protocol (CLP).

Product Description

Architecture

The data transceiver’s software architecture is based upon the FLEX Kernel realtime operating system. With the addition of ReFLEX stack software, a message manager, and the CLP default application, it provides a third-party embedded messaging Application Programmer Interface (API). Ownership of the serial port can be passed to a third-party application in place of the CLP application via an application framework provided by SmartSynch, Inc. An ARM core based micropro cessor provides the following features:

• 32-bit addressi ng

• 8, 16, and 32-bit data

• State-of-the-art softwar e development tools

• Industry standard Joint Test Action Group (JTAG) port

• Debugging support tools and environment via JTA G port The serial port data interface supports the CLP application. The CLP serial

interface commands the data transceiver to obtain status information about the network, transmit messages, and download received messages.

Components

The CreataLink2 XT hardware incorporates RF, digital, and analog circuitry on one Printed Circuit Board (PCB). The product contains no housing and is sold as an Original Equipment Manufacturer (OEM) product. The data transceiver has an industry-standard Sub-Miniature connector (SMA) connection for cabling to a remote antenna.

Air Interface

Data transport between the host application and the network requires data exchange protocols. In the radio porti on of the network, between the data trans ceiver and the base stati on, specialized R F protocols carry t he data. Thes e radio protocols are typically transparent in wireless applications. The FLEXsuite of application protocols must be used to transport data between applications on either side of network. FLEXsuite is available from Motorola, Inc. via a license agreement.

Air Interface Protocol

The data transceiver communicates across radio frequency channels via the ReFLEX protocol and an internal 900 MHz radio to operat e across the 12.5 kHz (ReFLEX 25) or 10 kHz (ReFLEX 50) RF sub-channels in the 900 MHz band. The network-specific configuration is constant for all like data transceivers on the network, and includes the network ID, channel list , base f rame, and ho me cont rol channel.

On ReFLEX ne tworks, the dat a transceive r automatic ally scans avai lable channe ls to locate an area channel that supports reliable communications. The data trans ceiver then performs a registration on the channel to establish a connection with the network. The registration process can be disabled via codeplug configuration for fixed location applications. The default configuration is Registration Off (always considered registered). A data transceiver operating in a typica l network, integrated into a product, is shown in operation, contact your network operator (paging carrier).

ReFLEX Network Operation

All two-way messaging networks that support two-way data communications with CreataLink2 XT device use the ReFLEX protocol. The network can be viewed as two separate one-way ne tworks. For messages dire cted to the data trans ceiver, the network controller rout es the messages to one of many high po wer transmitter sites. For messages from the data transceiver, a higher density of receiver sites are provided to compensate for the lower transmit power of the data transceiver.

The Global Positioni ng System (GPS) synchroni zes the downlink and upl ink paths, allowing downlink control of the uplink communications path. The network control ler schedules all transmissions from the data transceiver for optimal utilization of the uplink communications path.

Downlink messages are deli vered at a time when the data transceiver is guara nteed to be listening, as de fined by the data transcei ver battery-save mode/colla pse value.

Each unit is assigned certain frames in which its messages can be received. The personal address collapse and information services collapse values are used to schedule those frames a uni t mus t deco de f or mess ag es. If y ou u se the se coll apse d frames, you are trading battery life for the more frequent delivery of messages. Therefore, collapse frame use provides a battery-save mode and defines the per centage of the time the data transceiver is listening to the channel for messages. The remainder of the time the data transceiver is in a low-power state, and is not listening to the carrier channel for messages. It is important for the data transceiver and network controller to remain synchronized in order for mes sages to be delivered successfully.

The downlink is also referred to as the forward path. The uplink is also referred to

➧

as the reverse path.

Product Functionality

The data transceiver relies on system software for basic operational instructions, and on configura tion parameter values to meet data transceiver and network interface requirements.

Operating System

The data transcei ver operating system is based on the FLEX Kernel operating system. It can be reloaded or upgraded by the service center. For third-party software developers, tools are available to load in main operating code.

Power-up Operating Mode

The data transceive r operates in one of two power-up modes, depending on the condition of the supply voltage. If the supply voltage is not present, the data transceiver does not power up. Minimize cable length to limit the voltage drop across the cable during RF transmissions.

Supply Voltage At or Below Minimum Voltage

If the supply voltage level is less than or equal to 4V, the condition is detected and the data transceiver does not power up.

If the supply voltage is greater than 4V, but less than 5V, the data transceiver powers up but the performance will not be optimal. In this state, the data trans ceiver can still communicate with the resident host but:

• attempts to initiate messages are likely to fail.

• receive sensitivity is drast icall y affecte d.

• transmit power and the corresponding FCC spectral mask are degraded. When the supply volt age rises above 5V, the data transcei ver turns on and the unit

sucessfully enters the message-search mode.

Adequate Supply Voltage

A normal power-up occurs when the supply volta ge is above 5V. The data transcei ver automatically enters the message-search mode.

Message-Search Operating Mode

The message-search mode is the data tr ansceiv er’s main operat ing mode . When it powers up, the transceiver turns ON, and the unit begins to search for a valid ReFLEX frame. When the unit detects what appears to be a valid ReFLEX frame, it synchronizes with this channel and begins to decode the contents of the frame. The unit then attempts to register with the network (if the auto-registration feature is enabled). The default configuration is Regist ration Off (alway s considered reg is tered). After successful registration, the un it begins normal message de coding and searches for its assigned ReFLEX address(es).

If the data transceiver does not detect a valid ReFLEX frame wit hin approximately

1.5 minutes, the unit enters a low current cons umption mode. This mode conserves power for a pre-programmed length of time. When the time has elapsed, the unit attempts, once again, to acquire a valid ReFLEX frame. The unit alternates between

2-18 July 23, 2002

General CreataLink2 XT Hardware Integrator’s Guide

Product Functionality

searching for a valid ReFLEX frame and low current mode until it detects a valid ReFLEX frame.

If the data transceiver detects a valid ReFLEX frame and has become synchronized, but does not detect its address, the unit stays on the channel. It continuously decodes frame data and waits for its address(es).

Address Capability

The data transceiver can receive the following addresses:

• ReFLEX 25: 1 personal service address and 6 information service addresses

• ReFLEX 50: 2 personal service address and 1 information service address Additionally, for the ReFLEX 50 network only, each information service address

can have up to 32 subaddresses.

Duplicate Message Detection

To ensure proper message delivery, the data transceiver detects and cancels duplicate messages sent via the pagi ng system. If it finds a dupli cate message , the data transceiver discards it in a manner transparent to the host application.

Message Deletion

Unit IDs

When all message slots are occupied, or unused message memory is insufficient, the data transceiver deletes the oldest message to make room for a new message. Read messages are deleted before unread messages.

The data transceiver contains the following user identification strings within the codeplug:

• Serial number

• Electronic serial number (ESN) The strings are unique to each data transceiver.

Serial Number

The serial number consists of ten bytes of data stored in the data transceiver codeplug. It is factory-programmabl e only.

Electronic Serial Number (ESN)

The ESN consists of four bytes of data stored in the data transceiver codeplug. Each data transceiver is equipped with a unique serial number which serves as the reverse channel address of the data transceiver.

The serial number and ESN are data transceive r-specific. If the unit is changed for service, these numbers als o change. Th e carrier must be notified to make the PIN number point to the new serial number and ESN.
