Chapter 2. Module introduction

2.1. Description

The B900ss-20 is an FM radio transceiver with frequency hopping using an F.S.K modulation. The receiver is of a super beat oscillator type with heterodyning. It operates on the 902-928 MHz band and, therefore, is within U.S. FCC part 15.247 standard.

, and , and

Using the frequency synthesis, it has a maximum of 50 channels spaced by 150 kHz and can communicate with equipment via a serial interface with RS-232 standard and TTL levels. The serial link is completely programmable from 2400 up to 38400 Baud. The radio rate is established at 40 KBits/s.

The B900ss-20 uses the most recent technology of flash memory micro controller, which allows the user to update or to load new features through the serial link.

Many parameters are programmable through the se rial link and the default configuration is memorized in an EEPROM (ROM).

At each activation, the radio modem component is programmed with its configuration parameters (Channel, Speed, Protocol, etc.).

The default data are: RS-232 connection at 19,200 Baud, 8 bits, 1 stop bit, no parity, Frequency Table 1, slave modem.

All these parameters are accessible and modifiable with HAYES or AT commands.

2.2. Specifications

2.2.3. Schematic

See Appendix 1 for the principle schematics and the physical description of the card.

2.3. Available Configuration

2.3.1. Software Configuration

The B900ss-20 has 3 operating modes managed by the WinB900 Software (See Chapter

3):

• "Hayes".

• Point-to-Point.

• Network (future)

2.3.2. Hardware Configuration

All the B900SS product radio modules are delivered with the necessary software for operation. An evaluation Demo Kit (D900SS-20) is available at Adcon and allows the user to evaluate the radio module's performance. For more information, refer to Appendix 4.

With each radio module, the following is available:

• Series of programming ASCII messages to integrate the r a dio modems w ith a s erial link.

• A Windows configuration and test software programming the radio modules and testing the links (quality, distance, shadow area, etc.).

• A set of reference material available in CD-ROM.

Chapter 3. Basic Operation

3.1. General

The B900ss-20 can operate with three data communication modes:

• "Hayes" program the modem's parameters.

• "Point-to-Point" the function of an RS-485 cable). This mode automaticall y handles the data security (encapsulation, iterations, etc.)

• "Network": Client/Server structure. A Server will then be able to handle up to 16 clients simultaneously.

: inspired from the standard Hayes for voice modems, it is used to

: Two B900ss-20 replace a cable (the Hal f-duplex operation copies

Several B900ss-20 can work together, in accordance with a

3.2. "Hayes" Mode

The Hayes commands used by the radio module are in conformity with the Hayes protocol standard used for the voice modems. This p rotocol is based on the following principle: A data frame always starts with the two ASCII characters "AT" for "ATtention". The commands follow and are coded on one or several characters eventually with additional data.

Since the B900ss-20 does not operate exactly like a voice modem, it includes additional "AT" codes.

These commands are principally used to read and write the data in the confi guration registers stored in EEPROM.

3.3. "Point-to-Point" Mode

In this mode, two B900ss-20 Modems can co mmunicate together without getting any interference with other Modems.

For this purpose, their work is synchronized and constantly jumping frequency, avoiding interference with another transmitter: if one or more channels are busy, the data will be transmitted through another channel.

On the other hand, a "Personal Network" owns each set of modem. The data use d for a "Personal Network" cannot be intercepted by another "Personal Network". Each "Personal Network" owns a Master, which handles the communication (synchronization, priority, etc.) and a Slave that obeys its Master.

The first synchronization is named "Acquisition", and let s a Slave get acquainted with its Master (No. of Personal Network, Frequency Table used, etc.). Eventually, at each powered reset, the Slave will synchronize, then later be able to communicate with its Master. A "Lock" signal shows if a Slave has been synchronized with its Master or not.

Eventually, this synchronization is maintained all along the Master/Slave Dialogue.

A hardware flow control (RTS/CTS) is present on the Mo dems serial link in order to let the user know that the buffer (130 characters) starts to saturate. The alarm level is by default 130 characters and can be programmed through the S215 Regis ter.

Finally, an Ack_Tx signal, synchronized on the RTS signal, allows the transmitter user t o know if the receiver user has received a data frame or not.

For more specific information and to get the Time Series Charts, see the following chapter ("Advanced Part") and the Appendix 5.

3.4. "Network" Mode

In this mode, several B900ss-20 Modems are able to communicate with each other. Therefore, they constitute a Network handled by a Server Mode m that can hold up to 16 Client Modems (6 in the actual V0.2 version).

The acquisition procedures, the modems synchronization and the R TS/CTS and Ack_Tx signals handling are the same as for the "Point-to-Point" Mode.

On the other hand, when a frame is sent, it is necessary that a character indicating th e receiver modem number precedes the data frame. Also, in receiving the frame, a character preceding this frame indicates the transmitter modem.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference that may cause undesired operation.

3.5. Demo Kit Utilization

3.5.1. Installation and Connection

A D900SS-20 Demo Kit includes a plate that holds the B900ss-20 radio module, the antenna and the RS232 interface card.

In order to use it, connect the plate to a PC's COM Port through the supplied serial cable and connect the power supply (see picture).

On the interface card, ALL the switches have to be set to 'Off' and, of course, the On/Off switch has to be on the 'On' position.
