FTDI-QUADCOM converter with 4 virtual COM ports

Modern computers no longer have built-in RS232 ports, though many hardware still uses COM ports. Users have to use USB-RS232 converters, solve problems with separate power supply of such peripherals, there is a large number of wires and power supplies at the computer installation site.
To simplify the connection of such peripherals, a USB -> 4xRS232 converter with built-in switching of 5V or 12V supply voltage to one of the terminals of the RS232 ports is designed.

The possibility of switching one of the voltages to the COM-port connectors eliminates the need to connect a separate power supply to each of the peripherals. Voltage switching is carried out by jumpers separately for each COM-port.

In Fig. connections of switching contacts are shown:

PIN1 and PIN9 - pins 1 and 9 on the RS232 connector
RS232 pinout DSUB-9M

For example, the following combination of jumpers:

Converter FTDI-QADCOM USB 4 RS232 RI DCD will mean that the power is not connected to the pins of the connector, and the standard DCD and RI modem signals are connected to pins 1 and 9.

Another example:

This combination means that the 9 pin of the RS232 connector is connected to + 5V, and the standard DCD modem signal is connected to 1 terminal.

After the installation of commutating jumpers, it is strongly recommended to sign a label on each side of the enclosure or stick a label with the voltage supply connected to each connector on each external connector. In the future, this will avoid damage to the equipment due to a mismatch in the supply voltage or confusion when connecting the periphery.

The converter is powered by the voltage of the USB interface, however, in order to supply the external periphery to it, it is necessary to supply separate power supplies from powerful power supplies. For this purpose, the converter has connectors for power supply 5V and 12V

Arrangement of connectors on the converter:

- RS232 port connectors, 4 pcs.
