This converter uses MAX202-based level shifter for converting TTL (Transistor-Transistor Logic) -level serial to standard RS232 serial.
RS232 is widely used in radio modifications,phone flash, XBOX360 flash, GPS, vehicle detection, DVD flash, hard disk repair set-top box upgrade. It can be used to program STC MCU, NXP MCU,Renesas MCU, STM32 MCU, N+-2EC MCU.
This converter can be connected to an Arduino Serial pin (0,1) to convert standard Arduino ttl to RS232. It allows arduino talk to hundreds of RS232 devices.

RS-232 Maximum Cable Length
The maximum cable length for RS-232 is 50ft, but in practise depends on baud rate, cable specific capacitance and ambient noise. The table below contains some rules-of-thumb from experiments done by Texas Instruments years ago.
| Baud rate | Maximum range / cable length |
|---|---|
| 19200 | 50ft |
| 9600 | 500ft |
| 4800 | 1000ft |
