terminal of the Sabertooth 2x32 to the S1 terminal of the additional SyRen or Sabertooth drivers.
Connect the A1 terminal to the S2 terminals to enable reading back data, if the device supports it.
DIP Switch 6 enables or disables emergency stops.
If DIP switch 6 is in the OFF position, emergency stops are enabled. This emergency stop is active low
and internally pulled down. To enable the M1 output, connect the A1 terminal to 5V. To enable the M2
output, connect the A2 terminal to 5V. If these connections are broken and emergency stops are
enabled, the motors will stop immediately. This might be used for a safety E-stop in a machine, to only
allow motion while a dead man’s switch is held, or to detect a disconnected control cable. Emergency
stops provide a second way to shut down the machine if the host computer crashes or locks up, as well
as reacting more quickly than a PC might. Hardware emergency stops are required for some safety
regulations. Emergency stop is not available when using serial converter mode.
