In past days, many machine tool controls used by mould makers and tool and die makers, utilized a protocol to transfer their data. The makers of those controllers had realized that RS232 does not guarrantee a safe transfer and therefore, they implemented a method of data checking so that the control can recognize whether there has been a data loss or not. Data is transferred in blocks and each block has its special check sum that is proved by the control. This ACK-NAK method takes time over the network - especially when there is heavy traffic on the net. This causes the controller to wait for data and it stops which has a bad effect on the part itself and the processing time for the part.
The SCD runs the protocol only on the serial side so there is no data starvation. The SCD has always enough data in its local memory to smoothen the gaps in transmission on the network side. It can deliver data without delay to the control. On the network side only large blocks are transferred while on the serial side the ACK-NAK protocol is applied.

The Quinx SCD network adapter connects any Heidenhain controller with the network and allows accessing the part programs directly from the keyboard of the controller, using the dialog supplied by Heidenhain. It works without any delays, as if you had a PC beside every machine, using just one only Windows PC for many machines!
The advantage over all other network-based DNC systems is that no network traffic affects the data transfers and lets delay the single data packages. SCD has enough space in its local memory so that it can always deliver data to the controller with its maximum speed.

Mazak customers often save and load part programs with a special diskette drive. These devices become outdated as we offer you a highly comfortable alternative with the SCD adapters:

Load and save right from the Mazak control's keyboard

The Quinx SCD network adapters offer the same possibilities as Mazak's diskette drive, and even more!
