Input/Output circuitry
From high-speed encoder input
In tracking applications, connect Flyer’s high-speed inputs IN1 and IN2 to your position
encoder. These two inputs can accept input frequencies up to 40 kHz. Figure
6
-8 illustrates
a circuit for connecting position encoder outputs to the FH Flyer marking head.

Driving Flyer from high-speed encoder input
Important Note:
Remember that inputs IN1 and IN2 are unipolar. IN1_HI (Pin 9) and
IN2_HI (Pin 10) must connect to the high (V+) side of the input signal
while IN1_LO and IN2_LO must connect to the low or return side of
the signal.
Input/Output circuitry
Table
6
-7 lists possible ways you can connect Flyer inputs to your automation control circuits. For
example, IN0 (typically the ‘start mark’ signal) is a bipolar input—you can connect IN0_A to the circuit’ s
high
(+V) side and IN0_B to the low side (return or power supply common) or you can connect IN0_B to the
circuit’s high side and IN0_A to the low side.
High-speed inputs IN1/IN2 must always be wired so that IN1_HI and IN2_HI are connected to the high
(+V) side while IN1_LO and IN2_LO are always wired to the low side (return or power supply common).
Inputs IN3 through IN7 all share a common return line, IN3–IN7_B. If any of these inputs (IN3_A–
IN7_A) is wired to the high (+V) side, then all other inputs must be wired to the circuit’s high side. If your
wiring scheme has the common return line, IN3–IN7_B, wired to the high side, then all inputs, IN3_A–
IN7_A, must be wired to the circuit’s low side (return or power supply common).
