The 3onedata TTL-485-5P is a bi-directional port powered RS-485
to 5V TTL converter in a 9 pin format. It can convert any standard
full duplex RS-485 port to a 5V TTL signal and vice versa. The unit
is powered from the RS-485 data lines. It also supports data
direction auto-turnaround. Therefore, no external power or flow
control
is
required.
The
data
direction
auto-turnaround
automatically enables the TTL driver when data is present on the
RS-485 side making the device plug-and-play, requiring no software
drivers. The TTL-485-5P has a DB9 male connector on the RS485
side or 5-way terminal block and either a DB9 male connector or 5-
way terminal block on the TTL side. Separate terminal block is
included in package.
