* If your existing FH Smart head has the return (common) from input IN7 (IN7 RTN) wired to Pin 14, you must move this input
return connection to Pin 13, IN3–IN7_B, on the FH Flyer marking head.
** On the Flyer DB-25 User Interface connector, outputs OUT2–OUT7 share a common return—OUT2–7_B on Pin 2. This wiring
scheme assumes that OUT4/OUT5 RTN and OUT6/OUT7 RTN are all tied to the I/O supply’s DC common or return side (FH
Smart outputs are sinking current).
