1.Description:

 It is a RS232 to TTL serial port module.It can convert RS232 level to TTL level,can download SST,STC,NXP company's single-chip microcomputer,and can also be used for DVD upgrade,hard disk maintenance,flashing router firmware,GPS signal reading,mobile phone flashing and other functions.

2.Feature:

 1).It has an overvoltage protection circuit,which can better protect your computer and equipment.

 2).This module contains hard flow direction control.

 3).The RTS signal of the TTL end of this module is set to enable the bidirectional transceiver function,to prevent the SP3232 from causing chip oscillation when some pins are left floating,introducing high-frequency interference and increasing power consumption,thereby affecting the normal operation of the entire chip.

 4).This module is also designed with 2.54-pitch external pins reserved,you can connect to your device or perfboard through the reserved pin holes.

3.Parameter:

 1).Product Name:RS232 to TTL Serial Port Module

 2).Input Voltage:DC 3V-5V

 3).Input Interface:RS232

 4).Output Interface:TTL

 5).Work Temperature:-25?~85?

 6).Work Humidity:5%~95%RH

 7).Size:39.9*31.3*15mm

4.Pin Description:

 1).When the module is connected to the MCU at one end and the serial port of the PC computer at the other end or other DB9 plugs:

  1.1).VCC:DC 3V-5V

  1.2).GND:GND

  1.3).TXD:connect to MCU.RXD (signal flow:MCU.RXD << SP3232 << PC.TXD)

  1.4).RXD:connect to MCU.TXD (signal flow:MCU.TXD >> SP3232 >> PC.RXD)

  1.5).CTS:connect to MCU.CTS (signal flow:MCU.CTS << SP3232 << PC.RTS)

  1.6).RTS:connect to MCU.RTS (signal flow:MCU.RTS >> SP3232 >> PC.CTS)

 2).When one end of the module is connected to the MCU,and the other end is connected to the RS232 signal through the pin hole:

   2.1).VCC:connect to 3V-5V

   2.2).GND:GND

   2.3).TTL signal terminal:

      TXD:connect to MCU.RXD (signal flow:MCU.RXD << SP3232)

      RXD:connect to MCU.TXD (signal flow:MCU.TXD >> SP3232)

      CTS:connect to MCU.CTS (signal flow:MCU.CTS << SP3232)

      RTS:connect to MCU.RTS (signal flow:MCU.RTS >> SP3232)

   2.4).RS232 signal terminal:

      TXD:connect to RS232.RXD (signal flow:SP3232 >> RS232.RXD)

      RXD:Connect to RS232.TXD (signal flow:SP3232 << RS232.TXD)

      RTS:connect to RS232.RTS (signal flow:SP3232 << RS232.RTS)

      CTS:connect to RS232.CTS (signal flow:SP3232 >> RS232.CTS)

5. Note:

 1).Transceiver signal indicator:It will flash instantly when there is data,and it will go out when there is no data.

 2).The power ground and the TTL signal ground must be in common.

6.Application:

 1).Signal converter

 2).MCU download

 3).Flash the router firmware

7.Package:

 1).1pc RS232 to TTL Serial Port Module

 2).1pc 4P Cable
