7.3 RS232 serial link

7.3.1 General presentation

The RS232 interface performs the voltage level adaptation (V24/CMOS

⇔

V24/V28) between the internal WISMO module (DCE) and the external world

(DTE).

The RS232 interface is internally protected (by ESD protection) against

electrostatic surges on the RS232 lines.

Filtering guarantees:

EMI/RFI protection in input and output,

Signal smoothing.

Signals available on the RS232 serial link are:

TX data (CT103/TX),

RX data (CT104/RX),

Request To Send (CT105/RTS),

Clear To Send (CT106/CTS),

Data Terminal Ready (CT108-2/DTR),

Data Set Ready (CT107/DSR),

Data Carrier Detect (CT109/DCD),

Ring Indicator (CT125/RI).

Figure 14: RS232 Serial Link signals

RS232 interface has been designed to allow a certain flexibility in the use of the

serial interface signals. However, the use of TX, RX, CTS and RTS signals is

mandatory which is not the case for DTR, DSR, DCD and RI signals which can
be not used.
