How To Use the Parallel I/O Option

Linx 5900 & 7900

Input Sink

You can connect two types of input signal:

Sink Use this setting for an active low input.

Source Use this setting for an active high input.

Refer to ‘Input connections’ on page 29 for more information.

To configure the Input Sink options, perform the following steps.

1 At the Hardware page, select the Input Sink option to configure the electrical

characteristics of the inputs.

2 Press the Source key to change the highlighted input to ‘Source’.

The key label changes to ‘Sink’. If you press the key again, the setting changes to

‘Sink’ and the key label changes to ‘Source’.

In this example the keypad uses four inputs (outputs 5 to 8). You can change only

the inputs 1 to 4. If you highlight any of the other inputs (5 to 8), only the Back key

is available—the Source (or Sink) key is disabled.

Output Inversion

Use the Output Inversion option to configure the outputs to match the polarity of the

external device.

The Output Inversion page is like the Input Inversion page.

Output Sink

Two types of output signal are available:

Sink If you use this setting, the output operates like a switch. The external

device detects the state of the output—a low output is active, a high output

is not active.

Source If you use this setting, the output generates a voltage level—a high output

is active, a low output is not active.

The Output Sink page is like the Input Sink page.
