RS232 to RS422/RS485 isolated converter, K3
The K3 and K3-TB are in-line RS232 to RS422/RS485 converters for 0-38400 baud. They are powerd via the DTR and/or RTS signals from the RS232 sub-D9 port or externaly. On the RS422/RS485 side there is a sub-D9 or screw terminal block.

Description
The K3 is a general purpose RS232 to RS422 isolated interface converter for up to 38400 baud. Can also be used for RS485 if driver control is not required or if the RS232 device provides RTS Control. The K3 can also act as a Master on a 4-wire "RS485" bus. This converter has a female DB9 connector at both ends.
Do not confuse the K3 with imitations which claim to be self-powered but which in fact require power to be supplied to both sides of the converter, or which require about 40mA - far too much for any PC interface to supply.
- Isolation 100% tested at >1000V AC
- RS232 port-powered in most applications
- 0-38400 baud
- Very low supply current
- RS232 output swings above and below ground
- Sony professional compatible (also known as SMPTE) RS422 pinout
The K3-TB is a general purpose RS232 to RS422 isolated interface converter for up to 38400 baud. Can also be used for RS485 if driver control is not required or if the RS232 device provides RTS Control. The K3-TB can also act as a Master on a 4-wire "RS485" bus. This converter has a female DB9 connector on the RS232 port and a terminal block on the RS422 or RS485 port.
