K107A / K107B

Half-duplex RS485 serial bus with 3-point insulation

General Description

The K107A and K107B modules are half duplex serial buses with 3-point insulation.
Although both modules feature:

Timed automatic direction switching.
Communication speeds that can be configured by dip-switch,

They differ in the type of interface present on the X side:
K107A: RS485
K107B: RS232B
