Electroknit Serial Connections
Connecting to Brother Knitting Machines
The external Disk Drive Connection
Some models of knitting machine interface with an external floppy disk drive. By using this interface with the knitting machine, we can save and restore patterns from the machine.
The interface is a serial data connection at 9600 bits per second, with flow control signals, but the signal voltages are not RS-232 standard.
