(3) Optional input-output connector
When counters and the like are connected or as the destination to output the timing signal from the sewing
machine, an external input-output connector is prepared for the SC-951/950. In addition, as for the functions
of each connector pin, it is possible to change the already initialized functions or set a new function.
(Caution) Engineers who have electric knowledge should work when it is used.
