Operating Instructions SRIF 2002
Page 15 of 33
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.
Channel setting
8-pole plug-in connector Molex 53261-0890

Reference potential
A0,..., A6
(Pin 2,..., Pin8)
Digital inputs for the parallel channel setting
4V CMOS level binary-coded A0 = 2
0
and A6 = 2
6
(for channel numbers, see Chapter 7 Appendix, page 31;
for Pin numbering, see Chapter 2 Block Diagram, page 11)
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.
