The TTL-232-1 is an
industrial
grade (wide temperature range with surge & static
protection)
port-powered
bi-directional
RS232 to 5VDC TTL/CMOS converter,
which can be used to convert RS232 to 5VDC TTL/CMOS
compatible levels and vice versa.
The unit is powered from
the RS232 data line, and therefore, no external power or
RTS, DTR is required.

The TTL-485-2 is an
industrial
grade (wide temperature range with surge & static
protection) bi-directional
RS485 to TTL converter, which
can be used to convert RS485 to 5VDC TTL-compatible levels
and vice versa. It is also ideal for extending the TTL
distance.
The unit is powered from an external 5VDC power
supply. It supports data direction auto-turnaround, and
therefore, no flow control is required.
