The TTL-232-1 is
a compact, rugged, industrial-grade, port-powered, bi-directional
RS-232 to TTL converter, which can be used to convert RS-232 to 5VDC
TTL / CMOS compatible levels and vice versa.
The unit is efficiently
powered from the RS-232 data line, and the full-duplex RS232
to full-duplex TTL conversion eliminates the need of
auto-turnaround feature, therefore, it requires no external
power or software drivers, making the unit a highly reliable
and truly plug-and-play device
and an ideal solution for
all types of
mission-critical applications. Baud
rates: 300 to 115.2K Baud.

The TTL-485-2 is
a compact, rugged, industrial-grade, bi-directional
RS485 to TTL
converter, which can be used to convert RS485 to
5VDC TTL /
CMOS compatible levels and vice versa. The unit is powered from an external 5VDC
regulated power supply; it supports data direction auto-turnaround,
which automatically enables the RS485 transceiver when data
is present on the TTL side. Therefore, it requires no
software drivers or flow control, making the unit a highly reliable and truly plug-and-play device.
The built-in 120-Ohm
terminator can be turned ON or OFF through a simple jumper
setting, thus making the unit an ideal solution for all
types of
mission-critical applications.
