Maximum length for the IDE cable is 30cm.
Attention!
Check the Pin 1 marker of the cable and the connector before you power-on. Refer to the
technical manual of the installed drives because a wrong cable will immediately destroy the
drive and/or the MICROSPACE MSM945 board. In this case the warranty is void! Without
the technical manual you may not connect this type of drive.
The 44pin IDE connector on the drives is normally composed of the 44 pins, 2 open pins and
4 test pins, 50 pins in total. Leave the 4 test pins unconnected.
