===== Functional diagram =====

The RS232 standard is used for digital communication in serial mode, and because in addition to the data transfer lines it contains lines for controlling and controlling communication, it provides a stable connection resistant to interference. The voltages on the RS232 interface lines have values from ±7 V to ±15 V, therefore connection to a classic TTL digital system, whose signals take values of 0/3.3 V or 0/5 V requires the use of an appropriate converter, such as KAmod RS232H-ALL. 
The direction of signal conversion for all 8 signals is assigned in such a way that it corresponds to the master device - DTE/Host. The functional diagram shows which signals act as inputs and which as outputs on the TTL and RS232 sides.

On the converter board, on the lower description layer, there are precise markings for each signal on each connector:

</center>
The LOGIC I/O connector allows you to connect the KAmod RS232H-ALL converter with any digital system operating with a voltage of 3...5.5 V. 
The functions of the individual pins are as follows:
:* pin no. 1 - TTL output; DCD signal - Data Carrier Detect (signal detecting the carrier wave by the modem);
:* pin no. 2 - TTL output; RXD signal - Receive Data Line (data stream received from RS232, sent to DTE/Host);
:* pin no. 3 - TTL input; TXD signal – Transmit Data Line (data stream input from DTE/Host);
:* pin no. 4 - TTL input; DTR signal – Data Terminal Ready (readiness of DTE/Host for further cooperation with DCE/Modem);
:* pin no. 5 - ground, GND;
:* pin no. 6 - TTL output; DSR signal – Data Set Ready (readiness of DCE/Modem for further cooperation with DTE/Host);
:* pin no. 7 - TTL input; RTS signal – Request To Send (request to transmit data reported by DTE/Host);
:* pin no. 8 - TTL output; CTS signal – Clear To Send (readiness to transmit reported by DCE/Modem - confirms receipt of RTS signal);
:* pin no. 9 - TTL output; RI signal – Ring Indicator ("bell" signal).

Additional connectors enable easy connection of the KAmod RS232H-ALL converter in non-standard solutions:
:* Phoenix MC 3.81 mm connector enables easy connection of cables,
:* Goldpin 1x9 2.54 mm connector facilitates connection of contact and evaluation boards.
The pin numbers of both connectors correspond to the pin numbers of the DB9 connector. Detailed markings can be found on the converter board.

</center>
The LOGIC I/O connector contains pins that supply power to the KAmod RS232H-ALL converter
:* pin no. 10 – VIO; voltage input from the range of 3...5.5 V, which will correspond to logical "1" for all signals on the LOGIC I/O connector;
:* pin no. 11 – V+; allows you to connect a 4.5...5.5 V power supply, which goes to the 3 V voltage regulator built into the converter. The signals on the LOGIC I/O connector with a logical level of "1" will then have a voltage of 3 V, and a voltage of 3 V will be available on the VIO pin, with a current of up to 20 mA;
:* pin no. 12 - ground, GND.

* VIO – signaling correct power supply
* TX – signaling data transmission to the converter
* RX – signaling data reception from RS232
|}
</center>
The LED marked VIO indicates the presence of the converter's power supply voltage. In the case of connecting a 5 V power supply to the V+ contact, the diode also indicates the operation of the 3 V voltage regulator.
 
The TX and RX diodes flash to indicate the occurrence of active states on the data lines to the converter (TXD) and from the converter (RXD). Flashing diodes do not guarantee that the data is in the correct form. The active state on digital inputs/outputs is the logical state "L", i.e. voltage close to 0 V.

The dimensions of the KAmod RS232H-ALL converter are 65x30 mm and 72x31 with the DB9 connector). The height of the module is approx. 17 mm. The diameter of the mounting holes is 3.2 mm and their arrangement is shown in the drawing.
