OPTION CABLING DESCRIPTIONS
Evolution printers can accept inputs from external sources to control
product detection and timing circuits to track product speed (Encoders). These
device inputs are internally connected to pull-up resistors and drive optically
isolated devices and may be driven by open collector or switch contacts.
Each input requires the capability of sinking 12ma to ground as depicted in
the above circuit. Connection to the optional control port requires an RJ50
connector.
Below is an example of the external product detect eye supplied by
DIGITAL DESIGN INC part number C21006.
