RS232 to RS422/RS485 isolated converter, K3-ADE
The K3-ADE and K3-ADE-TB are in-line RS232 to RS422/RS485 isolated converters for 1200-38400 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. The K3-ADE contains a microprocessor which enables and disables the 2-wire RS485 half-duplex driver.

Description
The K3-ADE is a general purpose RS232 to RS422 or RS485 isolated converter which contains a microprocessor which enables and disables the RS485 driver according to the presence of RS232 data. The K3-ADE is intended for 2-wire RS485 applications. It is also suitable for 4-wire RS485 applications where the K3-ADE is on the Slave device.
The ADE function can be disabled, to operate as the K3-TB RS232 to RS422 converter. The K3-ADE has a DB9 female connector at both ends.
Do not confuse the K3-ADE 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.
- Automatic RS485 driver enable (ADE)
- Isolation 100% tested at >1000V AC
- RS232 port-powered in most applications
- 1200-38400 baud
- Very low supply current
- RS232 output swings above and below ground
