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.

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 serial 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.

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

10

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 radio modems with a serial

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.

11

Chapter 3. Basic Operation

3.1. General

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

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

program the modem's parameters.

• "Point-to-Point": Two B900ss-20 replace a cable (the Half-duplex operation copies

the function of an RS-485 cable). This mode automatically handles the data security

(encapsulation, iterations, etc.)

• "Network": Several B900ss-20 can work together, in accordance with a

Client/Server structure. A Server will then be able to handle up to 16 clients

simultaneously.

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 protocol 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 configuration

registers stored in EEPROM.

12

3.3. "Point-to-Point" Mode

In this mode, two B900ss-20 Modems can communicate 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 used 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 lets 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 Modems 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 Register.

Finally, an Ack_Tx signal, synchronized on the RTS signal, allows the transmitter user to

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.

13

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 Modem that can hold up to

16 Client Modems (6 in the actual V0.2 version).

The acquisition procedures, the modems synchronization and the RTS/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 the

receiver modem number precedes the data frame. Also, in receiving the frame, a

character preceding this frame indicates the transmitter modem.

14

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.

A Windows Software, 'WinB900' parameterizes and tests the B900ss-20 radio module.

In order to install it on your PC, launch 'Setup.exe' located on the CD-ROM supplied in

the Demo Kit, in the WinB900ss directory.

3.5.2. WinB900 Software Utilization in Point-to-Point Mode

The WinB900 Software can have two radio modules communicate between the COM1

and COM2 Port of a PC.

In a first phase, the two modems have to recognize each other ("Acquisition"). Go in

the "Quick Configuration" Menu, to the "Acquisition" Option. When this option is

selected, the software displays the following screen:

Select the table of the chosen channels as well as the No. of Personal network

(between 1 and 65535), and then launch the Acquisition clicking on the "Point-to-Point

Acquisition" button.

After clicking the button, the following message appears:

You can then quit the window. The Modems are synchronized (Green Led on).

16

Consequently, you can communicate between the two Modems with the ‘Point-to-

Point Dialogue’ Option from the "Quick Configuration" menu. When this option is

selected, the software displays the following screen:

The different fields and buttons are described below:

• "Sent Characters" Field

This side of the window sends the data entry.

• "Received Characters" Field

This side of the window shows the received data.

• "Test Frames" Selection

This selection allows the selection for the type of character sent. For example,

0x00 sends a character frame only made of a 0x00 binary character.

If the "Free" frame type is selected, the frame can be typed by the user in the

"Sent Character" field. This frame will then be sent.

17

• "Characters Count" Field

This field allows the selection of the character count to be sent if the selected test

frame type is any other than "free".

• Button: "Send"

This button sends the frame entered previously to the Characters section to be

sent.

• Button: "Continuous"

This button sends continuously the frame entered previously to the Data section

to be sent.

• Button: "Initialization"

This button reinitializes all the counter fields (Elapse Time, Character Count,

Frame Count, etc.)

• Button: "Stop"

3.5.3. Use of the WinB900 Software in Network Mode

The operating principle is similar to the Point-to-Point Mode.

In a first phase, the two modems have to recognize each other ("Acquisition"). Go in

the "Quick Configuration" Menu, to the "Network Acquisition" option. When this

option is selected, the software displays the following screen:

It should be noticed that if the Modem already holds a Network Number and Clients,

these two pieces of information will display in the "Network No." and "Clients Count".

If the Network No. is modified, the Server will then lose all the Clients already acquired.

Acquisition can be launched by clicking on the "Acquisition" button. After this, the

following message is displayed:

You can then quit the window. The Modems are synchronized (Green Led (On).

You can then communicate between the two Modems with the ‘Network Dialogue’

Option from the "Quick Configuration" Menu. When you pick this option, the software

displays the following:

The different fields and buttons are similar to the ones described in the previous

paragraph at the "Point-to-Point Dialogue" window. Only two new fields appear:

• "Network Number"

This field indicates the Network No. in the Server (COM1).

• "Client Number"

This field indicates the Modem No. in the Client (COM2).

3.5.4. Use of the "Terminal" or "HyperTerminal" Software

The Demo Kit or the B900ss-20 radio modules can also be handled from a Windows "HyperTerminal" or

"Terminal" type communication software.

The software has to be configured, in order to communicate at 19200 Baud, 8 bits, no parity, 1 stop bit through a

Serial link. To start with a correct configuration for HyperTerminal and Terminal, the following directories are

provided:

• "B900-CM1.ht" for "HyperTerminal" on COM1.

• "B900-CM2.ht" for "HyperTerminal" on COM2.

• "B900-CM1.trm" for "Terminal" on COM1.

• "B900-CM2.trm" for "Terminal" on COM2.

In this case, if your modems have already been configured and already been "Acquired", you can send data

frames with these software immediately. Otherwise, refer to Chapter 4 (Advanced Operation) to know how to use

the Registers.
