You are on: TTL to RS232 converters Page
Many of our products feature TTL Uart ports for transmitting and receiving serial data. We created these TTL to RS232 converters to allow those products to be connected to a standard PC serial port.
This unit is simply a RS232 to TTL convector IC on a board with connectors. We created this unit as a quick means to allow any TTL level uart to connect to the standard RS232 levels of a serial port. It requires a +5V dc supply to operate.
Its features are:
|
·
|
1 transmit and 1 receive line, full duplex.
|
|
·
|
Small unit size of 48 x 36mm
|
|
·
|
On board DB9 female connector for direct connect to a serial port.
|
Model: INT232-A
Shipping Weight: 0.07Kg
This unit is similar to our INT232-A above but has additional circuitry that draws power directly from the receive line of the RS232 port.
The INT232-B is a port powered TTL to RS232 converter. It will convert TTL level serial data to RS232 signal level data, and vice versa. Power for the unit is drawn from the receive line of the RS232 port thereby avoiding the need to provide a separate power supply.
Its features are:
|
·
|
1 transmit and 1 receive line, full duplex.
|
|
·
|
Power derived from the RS232 RX signal line.
|
|
·
|
Slim line case with DB9 connector ports.
|
|
·
|
Data rates up to 19200 baud when loaded in accordance with the EIA/TIA-232E
