Fusion Digital I/O Quick Start Guide

The Fusion® Series is our fourth generation relay controller offering

the ultimate relay control solution . . . without exception.

Fusion Series controllers support up to two ports of 8-bit digital input/output,

allowing users to read and control 5V digital signals using only a few simple

commands. When used for digital input applications, Fusion controllers are

capable of reading inputs such as switches, magnet sensors, and other contact

closure devices. Digital output makes it easy to control LEDs and some logic

circuits at very high speed.

Port Direction

The first step in using the Digital I/O features of Fusion series controllers is a

complete understanding of port direction. Each 8-bit port may be configured to

read inputs, write outputs, or both in combination. When the port is set to all

inputs, eight switches can be read as long as the input does not exceed 0 to 5 Volts

DC. When the port is set to all outputs, eight LEDs can be controlled by software,

allowing you to turn each LED on or off in any combination. It is easy to mix

inputs and outputs, allowing users to read four switches and control four LEDs.

Each I/O line on the Fusion controller may be configured to input or output, but

you must set the status of all eight I/O lines at one time using a single command.

Here’s an example:

236 2 255 Set I/O Lines 1 to 8 to Input Rx: 255

236 2 0 Set I/O Lines 1 to 8 to Output Rx: 0

236 2 15 Set I/O Lines 1-4 to Input, 5-8 to Output Rx: 15

The third byte in the Port Direction command is used to set the digital input or

output state of all eight data lines on the I/O port. Here’s how you decide what

this value should be:

Each I/O bit has a value associated, as shown below:

IO 8 IO 7 IO 6 IO 5 IO 4 IO 3 IO 2 IO 1

Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

128 64 32 16 8 4 2 1

Each of these 8 bits may be On or Off:

1 = On = Input

0 = Off = Output

If we turn on every other bit, we get this:

IO 8 IO 7 IO 6 IO 5 IO 4 IO 3 IO 2 IO 1

Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

In Out In Out In Out In Out

1 0 1 0 1 0 1 0

128 0 32 0 8 0 2 0

Bits 8, 6, 4, and 2 will be turned on, setting them to input; the other bits will

remain off, setting them to output.

Now we add the bits together:

128 + 32 + 8 + 2 = 170

Now we send the command:

236 2 170 Sets I/O Line 0 to Output

Sets I/O Line 1 to Input

Sets I/O Line 2 to Output

Sets I/O Line 3 to Input

Sets I/O Line 4 to Output

Sets I/O Line 5 to Input

Sets I/O Line 6 to Output

Sets I/O Line 7 to Input

Controller responds with: Rx: 170

In the screen shot above, the 8-bit I/O Port was configured for input and

output. I/O lines 1, 3, 5, 7 are outputs while I/O lines 2, 4, 6, 8 are set to

inputs. The value 85 was written to the port, turning on I/O lines 1, 3, 5,

and 7 (these lines can be used to drive LEDs). Inputs 2, 4, 6, and 8 can

be used to read switches, and will light RED if the input is high and you

click the “Read from Port” button.

EEPROM Memory

EEPROM Memory stores the state of each port when power

is first applied to the controller. Please review the Fusion

EEPROM Quick Start Guide for complete details.

EEPROM Memory Locations

280 Stores the Direction of Port 1

281 Stores the On/Off status of each bit of Port 1

282 Stores the Direction of Port 2

283 Stores the On/Off status of each bit of Port 2
