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 (Rev 1)
- Pins signal directions are reversed from an FTDI card
- Can be directly wired to FTDI connector
- GND
- CTS (out)
- VCC
- 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
