10. Appendix
10.1. CV-A50 IR emulating CV-M50 IR interfacing
The CV-A50 IR has a slightly different pin configuration on the 12-pin Hirose connector,
compared to the CV-M50 IR. This new configuration is compliant to the EIA-J standard.
This means, however, that the CV-A50 IR is not completely backward compatible with the CV-
M50 IR, in all cases (depending on the cable configuration).
This application note gives detailed instruction on how to change the pin configuration, by
changing internal solder jumpers.
Please note: Only a qualified electronics technician or engineer should make these changes.
