The 232OTTL is an RS-232 to TTL converter with 1500V isolation. Channels TD and RTS convert RS-232 to 0-5V TTL signals and channels RD and CTS convert 0-5V TTL signals to RS-232. The RS-232 side has a DB25 female connector pinned out to plug directly into the COM port of a computer or any other DTE device. The TTL side has a DB25 male connector.
- Signals: 4 channels, TD, RD, RTS, CTS RS-232 side pinned out as DCE TTL/CMOS compatible voltage levels (low < 0.8V, high > 2.0V) Inverted outputs (non-inverted available with modification) 38.4 kbps maximum
- Power
- RS-232 Side: Port-powered by TD, DTR, and RTS (requires two lines in any state) Or +12 to 16 VDC at 30 mA maximum on pins 25 and 12
- TTL Side: +12 to 16 VDC at 25 mA maximum on power jack or pins 25 and 12 (+5 VDC available with modification)
- Dimensions: 3.1 x 2.1 x 0.8 in (7.8 x 5.4 x 2.1 cm)
- Environment: 0 to 70°C
