How To Use the Parallel I/O Option 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.
How To Use the Parallel I/O Option 2.2.1 PCB layout CAUTION: Static-Sensitive Devices. The PCB contains static-sensitive devices. Take the following antistatic precautions when PCBs are touched. Wear an antistatic wrist strap and connect the lead to a good electrical earth. Always hold PCBs by their edges and do not touch the components, printed circuit tracks or connector pins.
2.3.2 Multi-stage alarm option The standard 5900 and 7900 printers have one alarm output. The Parallel I/O option allows the printer to generate four separate alarm outputs. If the multi-stage alarm option is fitted, you can use the four outputs to indicate four different alarm conditions. The alarm outputs are connected to a special socket at the rear of the printer cabinet.
How To Use the Parallel I/O Option 2.4.1 Configure a keypad You can use the PIO option to connect a keypad. The keypad uses some or all of the inputs and outputs. The following example shows a keypad that is connected to some inputs (A) and some outputs (B).
