Contents
DTE - RS-232 to TTL
- RS-232 to TTL converter
- The DTE (PC) has the male connector
- The DCE (peripheral) has the female.
H1 Connector
- Pins signal directions are reversed from an FTDI card
- Can be directly wired to FTDI connector
Pinout
- GND
- CTS (out)
- VCC (3.3V or 5V)
- TX (in)
- Rx (out)
- RTS (in)
- Pins 4 and 6 are backwards on Rev 1 card - corrected on Rev 2 card
H1 Connector (Rev 2)
- Signal referenced to H1 connector
- GND
- CTS (out)
- VCC
- Tx (in)
- RX (out)
- RTS (in)
Test Procedure
- FTDI-49MM
- DCE/DTE Cards
- 9 pin connectors plugged together
- FTDI loopback cable
- Run PuTTY
- 115,200 baud, RTS/CTS
- Type and it comes back
SP232A Application
- SP232ACN-L is 5V part
- ICL3232IBNZ is 3.3V or 5V part
DCE (reference)
- The DCE (Terminal) has the female connector
