On each BEX connected to a crate containing memory, the limit switches are used to specify the memory area covered by the crate. These values could also be set by a program.<br /> ==Connectors==<br /> The A and B connectors are used for I/O, the C connector is used for the [[ND-100 Bus]].<br /> <br /> ==I/O Devices on the card==<br /> none?<br /> <br /> ==References==<br /> *{{ND-doc|30.008.3 EN}}, page 201<br /> <br /> [[Category:ND-100 hardware]]</div>
