<strong>Transceivermodule</strong> 3 <strong>TRX433</strong>-<strong>10A</strong> / <strong>TRX868</strong>-<strong>10A</strong> (<strong>Vers</strong>. <strong>1.0E</strong>)<br />

Description<br />

The transceiver modules <strong>TRX433</strong>-<strong>10A</strong> / <strong>TRX868</strong>-<strong>10A</strong> are narrowband intelligent RS232 serial radiomodems<br />

for the ISM frequency bands at 433MHz / 868MHz.To build a wireless radio link between two RS232 devices<br />

two transceivers TRXnnn-<strong>10A</strong> are needed. The radio protocol, data integrity check and handshake are<br />

managed by the intelligent module itself. With an initial configuration the trasnsceiver can be put to the users<br />

need. A link control function with a RSSI voltage output can be used to test the quality of the radio link.<br />

With this transceivers you can realize excellent operating ranges.<br />

Features<br />

• easy configuration of communication parameters like frequency, baudrate, handshake and RF-mode<br />

through simple RS232 commands<br />

• integrated link control function<br />

• narrowband radio modem with 139 / 159 frequency channels in a 12.5kHz grid<br />

• RF-mode selects max. operating range (2km) max. speed (19kbits/s) or standard setting<br />

• compact size, small weight<br />

• status LED<br />

• three pincompatible versions A, B, C for different application types available.<br />

functionality (software) can be customized for special demands<br />

Applications<br />

• bidirectional RS232 data communication<br />

• fully replaces RS232 cables and provides galvanic isolation<br />

• wirless terminals, printers, displays<br />

• PC-PC data communication with terminalprogram (Hyperterminal)<br />

• with Evalkit3 range tests can be made<br />

We recommend the Evaluationkit 3 as a comfortable starting point for the first-time user of the TRXnnn-10<br />

and also as a reference design. With this kit you can realize within a few minutes a bidirectional serial PC-PC<br />

or PC to printer communication. You can also evaluate the operating distance in the field, without using any<br />

PC.

Family overview Radiotransceivers TRXnnn-10<br />

The Radiotransceivers of the <strong>TRX433</strong> and <strong>TRX868</strong> family are offered in three different versions, which are<br />

different in software and / or in hardware.<br />

Today the three versions A, B and C exists, with the following main differences:<br />

The three versions are covering the different needs of most applications as follow:<br />

<strong>Vers</strong>ion A is meant for simple applications as cable replacement e.g. between PC and peripheral devices, if<br />

the time delay of the radio link doesn’t play any role. The Transceiver himself checks for errors in the<br />

reception, sends an acknowledge back to the transmitter, which repeats the message in case of an error.<br />

The data are transmitted over radio after the buffer is full or if during a time of 3ms no further data are<br />

received. The Evalkit3 with the <strong>Vers</strong>ion A of the Transceiver is ideally suited to test the radio range.<br />

<strong>Vers</strong>ion B is used, if maximum transparency and control of the radio link is necessary or wished. There’s<br />

absolutely no coding or error check done. The input signal of the transmitter will be transmitted to the<br />

receiver transparently and with a minimal delay, so the receiver outputs a 1:1 copy of the transmitter input<br />

signal. This version nearly emulates a direct wire connection and gives maximum compatibility to any coding<br />

scheme and radio module of other manufacturers.<br />

<strong>Vers</strong>ion C with a transparent byte mode is used, if short response times are needed for RS232 data<br />

communication, and if you need full and easy control over many parameters of the communication. The<br />

serial bytes input at the transmitter side are sent almost immediately, so the data will be output at the<br />

receiver side only a few milliseconds later. If Error-checking is activated, the receiver outputs data only after<br />

they are checked and ok. Without internal errorchecking, the user has to implement this task itself within the<br />

application. <strong>Vers</strong>ion C works well with protocols like X, Y, Z-modem because of the minimal timedelay.<br />

1 tBIT_DATA : time of 1 Bit of the RS232 input data at the transmitter side<br />

t BIT_RADIO : time of 1 Bit of the selected radio datarate<br />

2<br />

if the radio datarate is fast enough with respect to the RS232 baudrate, a continuous dataflow will result<br />

without interruption by the Handshake.

<strong>Transceivermodule</strong> 6 <strong>TRX433</strong>-<strong>10A</strong> / <strong>TRX868</strong>-<strong>10A</strong> (<strong>Vers</strong>. <strong>1.0E</strong>)<br />

Linkcontrol mode<br />

Pin 9 (TEST) of the <strong>Transceivermodule</strong> has two functions, one for the flow-control (handshake) and the<br />

second function is the link-control. The link-control signals a valid, bidirectional link to a second partner-<br />

<strong>Transceivermodule</strong>.<br />

If TEST is set high through a resistor, the status of the radio-link to the partnermodem is output on the signal<br />

LINK\.<br />

LINK\ low means radio communication is OK<br />

LINK\ high means no radio communication<br />

Because TEST as well as LINK\ are double used and depending on the application are used as an input or<br />

an output, please take care not to connect two outputs without any current-limitation resistor together and<br />

also prevent the situation of an open input.<br />

As an example we refer to the application schematic of the Evalkit3, where the link-control is realized with a<br />

push-button and a LED.<br />

Important notice:<br />

Pin 9 must be connected with a Pulldown resistor (e.g. 100 k) to GND, so that the configuration mode cannot<br />

be activated unintentional during powerup of the <strong>Transceivermodule</strong>.<br />

If during powerup pin 9 is already high, the configuration mode is activated.<br />

RSSI (Received Signal Strenght indicator)<br />

The voltage at pin 8 (RSSI) is directly proportional to the receiving field intensity. The higher this voltage is<br />

the higher is also the receiving field intensity. The scaling is approx. 29dB/V, the offset or zero point is not<br />

calibrated and depends on the RF-mode.<br />

Powersupply<br />

The Radiotransceiver needs a clean supply voltage of min. 3.5V with a ripple of < 10mVpp.<br />

The power amplifier of the radio transmitter is directly connected to the input supply voltage, the rf-transmitter<br />

power therefore depends a little on the input supply voltage.<br />

If the supply of the <strong>Transceivermodule</strong> is switched, the voltage must always sink to 0V, before switching on<br />

the supply again. The supply voltage must rise within max. 50ms from 0V to 3.5V, so that the integrated<br />

microcontroller starts correctly. The voltage may never fall below 3.3 V, not even for a short time.<br />

If this cannot be ensured, the supply voltage must be supervised by a Voltagedetector, which ties the MCLR\<br />

input low as soon as the voltage drops below approx. 3.3V. See also application example with Evalkit3.<br />

Datainterface with 5V Systems<br />

The logic levels of the <strong>Transceivermodule</strong> are 3.3 Volt, according to the int. voltage regulator. The<br />

Transceiver can work directly at 5Volt systems, however during the high level of the 5V system an additional<br />

small current flows over the internal series resistors into the Transceiver. The input high-levels of the 5V<br />

system must be compatible to the 3.3V logic. See also simplified schematic of the Transceiver<br />

MCLR\ Reset<br />

The microcontroller of the <strong>Transceivermodule</strong> hasn’t got an internal Reset-detector, so the reset pin is<br />

externally accessible. We recommend an external Voltage detector with a trip voltage of > 3.3Volt (for<br />

standard TRX with 3.3V internal voltage regulator). If no such detector is used, please read the datasheet of<br />

the Microchip 16LF648A and ensure that the supply voltage conditions for powerup, brownout etc. can be<br />

met. The most problematic situation exists, when the supply voltage drops below 3.5 Volt and then again<br />

rises to normal condition, without going to nearly zero Volt.<br />

Anyway, with an external voltage detector, these problems are solved.<br />

If the conditions described under paragraph Powersupply are all met, the external reset-controller or voltage<br />

detector can be omitted.


<strong>Transceivermodule</strong> 7 <strong>TRX433</strong>-<strong>10A</strong> / <strong>TRX868</strong>-<strong>10A</strong> (<strong>Vers</strong>. <strong>1.0E</strong>)<br />

Timing and Handshake of communication<br />

The following example shows an unidirectional data communication of DEVICE1 to DEVICE2 with hardware<br />

handshake. If the data source sends more data than the Transceiver can buffer (>31 byte), a handshake is<br />

absolutely necessary, so that no data are lost. The databuffer of DEVICE1 is sent, as soon as it is full or if<br />

during the time of 3ms no more data arrive. The data communication is symmetrical and identical in both<br />

directions.<br />

The Transceiver data are double buffered (2x31 bytes) at the transmitter side. The first Buffer takes up the<br />

data from RS232 and passes them to the transmitter buffer before the start of the transmission. There the<br />

data are kept until an answer (ACK) from the receiver confirms the successful radio transmission. Meanwhile<br />

the first Buffer receives already new data from the RS232. The transmitter repeats the radio transmission of<br />

the data in the transmitter buffer as long as he receives a successful answer (ACK) from DEVICE2. Then,<br />

the next data block from the RS232 Buffer will be shifted into the transmitter buffer.<br />

The data buffer at the receiver-side is designed as a ringbuffer. This allows to receive new data over radio as<br />

soon as the buffer is going to be emptied into the RS232 interface.<br />

<strong>Transceivermodule</strong> 9 <strong>TRX433</strong>-<strong>10A</strong> / <strong>TRX868</strong>-<strong>10A</strong> (<strong>Vers</strong>. <strong>1.0E</strong>)<br />

Configuration setup<br />

If the signal CFG (Pin9) is held high during the powerup of the Transceiver, the module enters into the<br />

configuration mode (this would also happen if the yellow button was pushed on Evalkit3 while powerup).<br />

The configuration works with a fixed baudrate of 19.2kbaud and the following parameters:<br />

Configuration: - Baudrate: 19.2 kbaud<br />

- Databits: 8 Bit’s<br />

- Parity: none<br />

- Stop-Bit: 1<br />

- Handshake none<br />

The most convenient way to configure the Transceiver is to use the Evalkit3 together with Hyperterminal,<br />

where you will see the following screen.<br />

Screen output in Hyperterminal after start of configuration:<br />

If you use the Evalkit3 for configuration, you can switch the supply of the Transceiver by means of the<br />

„connect“ and „disconnect“ button of Hyperterminal (this are the buttons with the telefon symbol).<br />

Now you can setup the following 4 Parameters (Input numbers, ENTER, ESC)<br />

frequency: at 433MHz- band: possible frequencies: 1-139 (in 12.5kHz-steps)<br />

001 = 433.0625 MHz (also input the leading zeros!)<br />

070 = 433.9250 MHz<br />

139 = 434.7875 MHz<br />

At 868MHz- band: possible frequencies: 1-159 (in 12.5kHz-steps)<br />

001 = 868.0125 MHz (also input the leading zeros!)<br />

080 = 869.0000 MHz<br />

159 = 869.9875 MHz<br />

baudrate: Baudrate for RS-232 Interface:<br />

1 = 1.2 kbaud<br />

2 = 2.4 kbaud<br />

3 = 4.8 kbaud<br />

4 = 9.6 kbaud<br />

5 = 19.2 kbaud<br />

6 = 38.4 kbaud<br />

7 = 57.6 kbaud


<strong>Transceivermodule</strong> 10 <strong>TRX433</strong>-<strong>10A</strong> / <strong>TRX868</strong>-<strong>10A</strong> (<strong>Vers</strong>. <strong>1.0E</strong>)<br />

rf-mode: Setup for radio transmission:<br />

1 = 19.2 kbit radio datarate, 100kHz channel grid (Maximum data speed)<br />

2 = 4.8 kbit radio datarate, 25kHz channel grid (Standard setup)<br />

3 = 1.2 kbit radio datarate, 12.5kHz channel grid (Maximum sensitivity)<br />

handshake: Flow control: (for reliable communication flow control should always be activated)<br />

1 = no flow control<br />

2 = Hardware (RTS/CTS)<br />

3 = Software (XON/XOFF)<br />

The configuration mode can be terminated with the ESC-Key or it will terminate automatically after 1 Minute<br />

of no data activity.<br />

If you want a parameter not to change, hit the Enter-Key without any number input.<br />

The configuration is saved into the EEPROM of the <strong>Transceivermodule</strong> and will remain there permanently.<br />

Notice:<br />

• The configuration must be done always with 19.2kbaud, even if you configured another baudrate<br />

• The signal RTS/CFG (Pin 9) must be tied to a logic low level by a pulldown resistor during normal<br />

operation, in order not to activate the configuration mode during powerup.<br />

• Always input the numbers with three figures, including the leading zeros<br />

• With the standard 868MHz Transceiver, only use rf-mode = 3, if the temperature range in use is<br />

between 5°C and 40°C.

Most important factors are: The height of the antenna over ground, electromagnetical noise near the receiver<br />

(from PC’s, monitors etc.), other radio transmitters, type of ground, transmitters within the same frequency<br />

band, transmitting on adjacent channels.<br />

If you look for a maximum in operating distance, we recommend the 433 MHz frequency band. If at the place<br />

of use there are other systems using the same frequency band, the 868MHz system may reach a better<br />

operating distance in this case.<br />

With the 433MHz Evalkit3 under normal conditions, operating distances in excess of 4km were measured in<br />

the countryside. The above given distances therefore are rather conservative values.<br />

To setup the frequency see paragraph Configuration.<br />

Note<br />

The frequency channel of two individually operating Transceivers must differ at least the amount of channels<br />

occupied by the selected rf-mode, in order the spectrum of the two Transceivers do not overlap.<br />

According to the selected RF-mode, 1, 2 or 8 channel numbers are occupied.<br />

The higher the channel distance of two Transceiver pairs operating simultaneously in the same range, the<br />

better is the operating distance of each individual pair.

To setup the frequency see paragraph Configuration.<br />

Note<br />

The frequency channel of two individually operating Transceivers must differ at least the amount of channels<br />

occupied by the selected rf-mode, in order the spectrum of the two Transceivers do not overlap.<br />

According to the selected RF-mode, 1, 2 or 8 channel numbers are occupied.<br />

The higher the channel distance of two Transceiver pairs operating simultaneously in the same range, the<br />

better is the operating distance of each individual pair.
