How To Use the Parallel I/O Option

Linx 5900 & 7900

2 About the Parallel I/O option

The Parallel I/O (Parallel Input/Output) option allows a remote host device (PLC or

computer) to control the printer or to monitor the printer status. The Parallel I/O unit has

eight inputs and eight outputs.

You can assign the inputs to a number of printer functions. For example:

• Start or stop the printer.

• Select a message from a list.

You can connect a number of photocells to the inputs to detect the size of the product. The

printer uses the photocells states to select the correct message for each size automatically.

You can use each output to indicate an event that you define. For example:

• A warning or failure condition.

• The status of the ink jet.

2.1 Applications

The following examples are typical applications for the PIO option.

• You can use a Programmable Logic Controller (PLC) to control the printer. The PLC can

stop the printer at the end of the day, or pause the print if the machine guards are open.

• You can use a group of photocells to detect the size of the product and select the correct

message for the product.

2.2 Components

The Parallel I/O option is supplied as a kit of parts, as shown in the following illustration.
