How To Use the Parallel I/O Option
Linx 5900 & 7900
1 Introduction
This document tells you how you configure the PIO (Parallel Input/Output) option on the
5900 and 7900 printer.s
You need a User Level C password to perform all the tasks that are described in this
document.
IMPORTANT: The PIO option has some configuration links on the PCB. The link settings
depend on how you use the PIO option. Read this document carefully and
make sure that the link positions are correct for your application before the
PCB is installed in the printer.
(Normally, a maintenance technician performs the installation. The installation procedure is
not described in this document.)
1.1 Health and Safety
Make sure that you read and understand the Health and Safety information in the ‘Safety’
section of the Linx 5900 & 7900 Quick Start Guide.

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.
Figure 1. PIO Option
The kit contains the blanking plate (1), the main PCB (2), the IDC connector (3), and the
fixing bracket (4).

2.3 Optional accessories
2.3.1 Keypad option
You can fit a keypad to the printer and use the keypad to operate some or all of the inputs
manually. You can assign the keypad to some inputs and use a remote host device to
operate the other inputs.
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. Refer to the section
‘Multi-stage alarm connectors’ on page 33 for more information about these connections.
2.4 Parallel I/O setup
To configure the Parallel I/O unit from the Print Monitor page, press the Menu key. Then
select Setup > Parallel I/O to display the Parallel I/O page.

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). The keypad in this example uses three inputs (1 to 3) and four
outputs (1 to 4).
Figure 4. Keypad connections and key numbers
This arrangement provides 3 x 4 = 12 keys.
You must assign a continuous range of inputs and a continuous range of outputs (for
example, inputs 1 to 4, or outputs 3 to 6). You cannot assign an input or output range that is
not continuous (for example, outputs 1 and 3).
NOTE: If you connect a keypad, enter the keypad information before you configure the
inputs and outputs.
Refer to ‘Link positions’ on page 29 and make sure that you set the following links on the
PIO PCB before the PCB is installed:
LK2: Position A (selects the internal 0 volts connection for the inputs)
LK3: Position A (selects the internal 24 volts connection for the inputs)
LK4: Position A (selects the internal 24 volts connection for the outputs)
LK5: Position A (selects the internal 0 volts connection for the outputs)

3Do one of the following:
•Select another combination of input states from the list.
•Press the Exit key to return to the previous page (see Figure 21 on page 14).
Define the Detection settings
You must make sure that the printer can detect the state of the input signal
correctly. (Electrical noise or timing problems can cause an error.) You can define
the detection method that is used. A reliable detection depends on the combination
of the input line state and the change of state of the latch input line (pin 19 in
Figure 4 on page 31).

(The ‘high’ level is +24 V and the ‘low’ level is 0 V.)
3Highlight the detection method that you require and press the OK key to return to
the Edit Detection page.
Detection option Detection event
Latch on Board One The voltage on the latch input line changes from either
a high level to a low level, or from a low level to a high
level.
Latch on Board One Rising Edge The voltage on the latch input line changes from a low
level to a high level.
Latch on Board One Falling Edge The voltage on a the latch input line changes from a
high level to a low level.
After Inputs are Steady The input voltage on the selected input is held in the
new state for a minimum period. (The After Inputs are
Steady option does not use the latch input line.)

If you use the After Inputs are Steady option, the Edit Detection page has an
additional option.
Figure 28. Edit Detection page
4Set the Steady Time option as required to define the minimum period. You can set
the value to 10, 50, or 100 milliseconds. (If you use a relay, the Steady Time option
provides a debounce period for the relay contacts.)
5Press the Exit key to return to the Edit Inputs page.
Numeric Remote Field
You can use a range of inputs to generate a numeric value which is put into a remote field.
The value is encoded as a binary number. For example, a range of four inputs can generate
any binary number from ‘0000’ to ‘1111’ (decimal 0 to 15).
To use this feature, perform the following steps.
1Set the input range (for example 8 to 1) as shown in ‘Configure the inputs’ on
page 12.
Figure 29. New Input page
2Set the Numeric Remote Field option to Yes.
