Retrofitting An Ar4201 With An Ar6201-(X0X); Pin Compatibility - Becker AR6201 Installation And Operation Manual

2.10 Retrofitting an AR4201 with an AR6201-(X0X)

In most cases, a retrofit of the AR4201 with an AR6201-(X0X) does not
cause any problem.
However, in some cases differences may occur because not all pins are
fully compatible.
!!! To connect the AR6201-(X0X) to an AR4201 wiring does not cause any
defect, neither to the AR6201-(X0X) nor to the aircraft installation.
