General purpose I/O extended functionality

RS485 interface The S215 register allows enabling the management of the control lines (/RE and DE lines) of most RS485 buffer. The following figures illustrate the RS485 wiring and the configuration required for activating the DE and /RE management. Even one line is sufficien t, for m ore flexibility two different lines could managed the DE and RE RS485 control lines. Hereafter a connection example with both lines or one line only.

By default, the DE and RE lines are asserted LOW, allowing the reception of characters from the RS485 differential bus. The DE and RE lines are asserted HIGH only when one or several characters ha ve to be transmitted over the RS485 differential bus: when a radio frame is demodulated, the lines are asserted HIGH and then the data extra cted from the radio frame are sent to the module TXD line and therefore to the RS485 differential bus. When the last character has been transmitted over the RS485 differential bus, the lines are asserted LOW.

Channel adjustment

The S200 register allows choosing the desired channel and the associated radio rate (
see chapter “AT commands”
)

Radio rate selection

For 869 MHz version, the Radio rate selection is automatically done when setting the channel number:
If you choose a channel number 14 (Narrow Band), the radio rate will automatically switch to 10 kbit/s. If you choose a channel number < 14, the module will operate in the Wide Band configuration. The radio rate will switch automatically to 57600 bit/s.

Particular attention is required for product installation. In the case where several links must works in the same area (independently of the channel positions), the minimum distance between 2 products belonging to different radio links is 3 meters. Even with this precaution (depending of the product environment), channel rejection could be reduced.

RSSI reading

The RSSI (Received Strength Signal Indicator) gives an indication for the received power level. It could be accessed with AT commands (ATS230?<cr> command).
The RSSI level is only a n indication. Use this level with care due to the dispersion between components.
The operating temperature could also have an impact on these dispersions.
The RSSI level could also indicate the potential presence of any jammer in the used channel.
The RSSI is a necessary but not sufficient condition to obtain a correct reception.

Transceiver operating mode

Two operating modes are available :
1. Command mode (usage of AT commands)
2. Transceiver or normal mode (serial data are transmitted on radio link)
At power up the transceiver is in transceiver mode: it is able to send / receive data to / from the radio link according to its current parameter configuration.

Command mode

The command mode is used to read and update the modem configuration registers using AT command.
N
OTE
The AT command can be locked using ATPWD command. In command mode, the radio is inhibited (reception and transmission),
excepted when using test command.
Entering command mode : issues on the serial link a +++ sequence. The
sequence of 3 consecutive + characters is accepted only if no character have been seen before and after the +++ sequence. Register (S214) defines the silence duration.
Tips 1: if you are using a terminal (such as Hyperterm), you have to send
the +++ sequence using a text file (first create a text file containing only the +++ characters, and then use in Hyperterm the command “Send text file” in the “Transfer menu”)

Transceiver mode

In transceiver mode, two protocols are available:
1. Transparent mode, without flow control.
2. Addressed mode, with flow control (see register S216)
The communication is always half-duplex. The radio transmission is proces sed prior to the radio reception (when the transceiver is sending a radio frame, it is not able to decode any incoming radio frame).
If no data are sent on the serial link, the modem is waiting for radio reception. Each radio frame sent by another modem is received and the validated data extracted from the radio frame are sent on the serial link. When the last character has been sent on the serial link, it is possible to send an answer at least 100 µs (minimum) after the end of this last character.
All the data received on the serial link are encapsulated in a radio frame. The radio frame format depends on the used protocol.
When acting as transceiver, the radio frame transmission always starts under the following conditions : Detection of a silence on the serial link (greater than S217) after the reception of the latest character. Or when the number of received characters from the serial link is higher or equal to the maximum radio frame size (S218).

Transparent mode

In transparent mode, the modem acts as a wire serial link. It means that alternately, the modem sends on the radio the data received from the serial link and sends on the serial link the data received from the radio. The radio frame format is :
<Preamble><synchro>DATA <postambule>. Preamble, synchronisation and postambule are used for the radio reception.

Addressed mode

In transmission mode, data received on the seria l lin k are sent on the radio link with the following format :
<Preamble><synchro><Address> DATA <postambule>. Preamble, synchronisation and postambule are used for the radio reception.
The Address field is set up with S256 value (LSB first).
In reception mode: The <Address> field of the radio frame is
checked with the reception address (S252)
If the radio frame address ma tches the transceiver reception address (S252), DATA (and only DATA) are transmitted on the
Otherwise received data are silently discarded.

Transceiver state machine

When operating in transceiver mode the 'RF transmission' state machine is : Idle state of the transceiver : by default the transceiver is waiting for
incoming data on the RS232 link and for incoming radio frame on the radio link.
The RS232 link has a higher priority than the radio link (if a radio frame is demodulated meanwhile some RS232 characters are detected on the serial

link, the radio frame will be discarded and the RS232 incoming data will be processed).
Processing incoming RS232 data : the incoming RS232 data are internally buffered. The buffered data are sent in a radio frame (the RF modulation is started) when almost one of the following conditions occurs: if a break (silence greater than S217 timeout) is detected on the incoming serial flow (no more data to be sent). if the radio buffer size is reached (the number of buffered characters are equal or greater than the S218 size).
Processing incoming radio frame : the valid data are extracted from the incoming radio frame and internally buffered. The buffered data are sent on the fly to the RS232 module output.

streaming mode without flow control. Be careful Î using a serial rate greater to the radio rate must produce character losts if the flow c ontrol is not used. If the radio rate is equal to the serial ra te, the radio frame is longer than the serial frame, due to radio protocol overhead; but the radio overhead will be generated only when the radio transmission begins Î this overhead will be absorbed by internal buffer size. For example, if the current radio rate is 10 kbit/s, a serial rate of 9 600 should be used without flow control, while using a serial rate of 19 200 (with 10 kbit/s for the radio rate) will produce data overrun. For avoiding character lost, you should :
1. use the flow control (addressed mode with hardware
handshake)
2. or use a serial rate lower or equal to the rad i o rate
3. or limit the size of serial data to the maximum size of the
