3.1 Radio transmission
The SRIF 2002 comprises all necessary functions for the transmission of digital
data in the 5.8 GHz range in transmit and receive mode. It is possible to set 127
frequencies (channels) independent of each other. The channels can either be
programmed via an additional asynchronous interface (UART protocol: 4800 Baud;
8N1) or set via 7 binary-coded parallel control lines. The parallel setting always has
priority, i.e. a serial programming is only possible if the parallel interface is
disconnected or the word “0” is set at the parallel interface (all switches open). The
SRIF 2002 supplies an analog RSSI signal.
The SRIF 2002 operates in the half duplex mode. The SRIF 2002 is in the receive
mode as a standard. As soon as any transmission data are applied to the data
input (TXD) and the control signal pin2 is set to TX, the module switches to the
transmit mode and transmits the data.
Figure 2: Schematic representation of the radio transmission
Operating modes of the SRIF2002:
●Receive mode The receive mode is the normal operating state of
the module.
●Transmit mode The module automatically changes into the
transmit mode when a valid signal has been
received via the UART and after the completion of
a just received block via the radio path.
●Stand-by mode The stand-by mode is activated at wrong
parameterization.

The SRIF 2002 communicates via a serial asynchronous interface
(UART protocol). The transfer rate has to be preset by the user. Transfer rates of
9600, 19200, 38400, 57600 and 115200 can be set via the quadruple DIP switch of
the SRIF 2002 (see Figure 1, page 11). Data communication is always 8E1 (8 data
bits, even parity, 1 stop bit).
3.2 Parameterization via the parallel interface
The SRIF 2002 has to be parameterized via the parallel interface, for example if it
is used in the battery adapter (BA) / ammeter or in the TRX245 of the ECOS range.
This presetting can be overwritten with the help of the additional asynchronous
serial interface (UART protocol: 4800 baud; 8N1 (see Chapter 3.3 Serial
parameterization, page 17).
The following settings have to be carried out:
Baud rate setting
The SRIF 2002 carries out the setting of the DIP switch after every power-on reset.
See Chapter 4 Settings, page 23, for a table listing of the settings.

7 parallel inputs (A0 = LSB, A6 = MSB) and one reference line (GND) are used.
The address lines are equipped with internal pull-up resistances at the radio link
module.

The coding switch to be connected short-circuits the selected address lines with
the reference line (inverse logic !).
Due to the missing eighth address line, the settings on the coding switch starting
from 8x are interpreted as entries starting from 0x.

3.3 Serial parameterization
For the use of the SRIF 2002 radio link module in the MPS, hand-held terminal,
and MDA devices of the ECOS range, the channel number is set via the serial
interface.
The serial programming is carried out via the additional asynchronous serial
interface (UART protocol: 4800 baud; 8N1) and offers the following options for
setting or polling the SRIF 2002:
•Version and setting inquiry
•Channel setting
•Overwriting the baud rate setting
•Connecting and disconnecting the RSSI extension
The meaning of the settings is explained in the following.
The transmission of the data via the serial interface is carried out in the form of a
string consisting of 4 characters. The first three characters encode the command
(numeric characters only), the fourth character is always “#”. If a valid command
has been detected, the SRIF 2002 responses - unless it is a version inquiry - with
the string sent via the RxD line (pin 4). The response is also carried out with the
UART protocol 4800 baud, 8N1.
Note
Communication via the additional asynchronous serial interface is only possible if
the parallel interface is disconnected or the word “0” is set at the parallel interface
(all switches open).
With the “serial parameterization”, the SRIF 2002 starts in the stand-by mode after
a power-on and waits for a serial channel setting. The SRIF 2002 only changes into
the receive mode after a successful parameterization.
Channel setting
The SRIF 2002 operates with a frequency pattern of 1,173.23 kHz. For optimum
use of the released ISM band (5.725 up to 5.875 GHz), the frequency of
5,726.0866 MHz was set for channel 1.
Example: Setting for channel 04 (hex); corresponds to a frequency of
5,729.6063 MHz: 035#
for the frequency table, see Chapter 7 Appendix, page 31).

RSSI voltage / RSSI extension
The SRIF 2002 offers two settings for the output of RSSI voltage. With the "RSSI
extension" activated in the delivery state, the SRIF 2002 always raises the RSSI
voltage to a level of approx. 4V if received data are output at pin 4 (RxD).
If the “RSSI extension” is switched off, the RSSI level is not raised to 4 Volt during
the data output.

OFF 996#

Version and setting inquiry
The SRIF 2002 responds to the command 990# (version inquiry) with its soft- and
hardware-dependent version number and its current settings for channel, transfer
rate, status of the RSSI extension. The “Special Channels” switch (SRIF 2000:
998/999) is also output to ensure compatibility with the SRIF2000. This switch has
no function for the SRIF2002.
The version number lies within the range of 200 and 299. The individual pieces of
information are separated from each other by “,” and are contained in the response
string in the above mentioned sequence (202,035,994,997,998#.)
