Function description:

"Open": Control port outputs low level (default)

"Off": Control port outputs high level (default)

Jog: input a jog command, the port outputs a low level, and returns to a high level after 1 second

Self-locking: Input the self-locking command, the port will output low level, input the self-locking command again, the port will output high level, and so on

Interlock: Input channel 1 interlock command, port 1 outputs low level, and ports 2-8 output high level; press input channel 2 to interlock, port 2 outputs low level, and ports 1/3-8 output high level; And so on
