(English) IT-485P5-TTL


The Intellisystem IT-485P5-TTL 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 IT-485P5-TTL 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.
