Description

The K2 is a non-isolated RS232 to RS422 or RS485 converter for 0-115200 baud. It is primarily for RS232 to RS422 conversion. For RS485 use, RTS Control is required from the RS232 device. The K2 can also act as a Master on a 4-wire "RS485" bus. The K2 has a DB9 female connector at both ends.

RS232 port-powered in most applications
Very low supply current
RS232 output swings above and below ground, for maximum compatibility
Sony professional compatible (also known as SMPTE) RS422 pinout
