Installation
+V (Positive of Supplied Power) is "red" wire;
to 24VDC(Positive of Supplied Power) is "Brown" wire;
A(Signal A) is "Green" wire;
0V (Negative of Supplied Power) is "Black" wire.
is "Blue" wire.
CAUTION：Printer can only use three of these wires. For the other wire of the encoder they must be
isolated with each other, or faults may happen.
For different brands of encoder, the definition of color wiring is different, and you can find these
three wires according to the examples. (Refer to the label when there is no encoder instruction
book)
4．Connect the wire of encoder to IOU by three hole on the right of X4 port (Refer to the photo below)
CAUTION：Wrong wiring method may burn down the encoder or IOU. Ensure it before turn on the
machine.
The definition of wiring from right to left is: +V (Positive of Supplied Power) connect to VDD; A(Signal
A) connect to ENC; 0V (Negative of Supplied Power) connect to COM.
5．Push the power button and adjust each parameter by the order below.
1. Message Width
It is used to adjust the width of the printed message on the products when the
encoder status is off (see "Encoder Setup"). The higher the setup value is, the
narrower the width of the message (the same product moving speed).
It is used to adjust the print quality when the encoder status is on (see
"Encoder Setup"). The lower the setup value is, the better the print quality.
