CASINO 8 Channel Digital IN/OUT Module

Introduction

The 8 channel digital IN/OUT module offers 8 digital input channels and 8 digital output channels. Connection to the board is done by serial com port. The module can be used to control electrical devices, e.g. heaters, vans, pumps, valves, solid-state relays and other power equipment for home automation as well as industrial automation.
The module’s 8 digital inputs can be used to determine the state of push buttons, switches, relay contacts, limit or safety switches or other digital signals. The number of inputs/outputs can be further expanded by connecting more cards to the PC.
The 8 channel digital IN/OUT module is controlled by simple commands. A complete overview of commands can be found in the COMMANDS section below. You can write custom applications with every programming language supporting COM port functionality.
The diagnostic application (IO8.EXE) can also be used as command line application. This way it is possible to control the module by using batch file. Example batch files are included with the diagnostic software.

Connections

Power connector

The operating voltage is connected to clamp X1. The 8 IN/OUT board needs a supply voltage of +5V.
The second voltage (+12V) is just routed to the output screw terminals and finally used for supplying the output circuit.

Instead of connecting the +12V you can connect up to +24V.
The ground connection (GND) of both voltage must be connected.
The interfacing of +5V, +12V and GND is printed on the board.
You can use the PC power supply or a separate power supply.
Depends on the load be sure the power supply is strong enough!

Com (USB) port

Connection to the computer or other micro controller circuit board is done via 9-pole RS232 connector X2. Be sure the RS232 cable is not longer than 3m.

In order to operate the 8 channel digital IN/OUT module via USB, you can use a RS232 to USB converter.

COM port settings: Baud 19200, Data bits 8, Parity none,Stop bits 1, Handshaking none

Inputs

Input is generally HIGH (1), connection to ground makes the input LOW (0).
The inputs can be connected to the screw terminals X8 – X12, or to the pin header JP1.
A input wants to have GND as signal!
Here you can see an example how to connect a simple push button to input IN1.

Hint: The outputs are open collector outputs, and we switch GND.
COM is connected to the power supply COM, so you can use for example +12V or +24V or whatever voltage needed.

Commands

Serial port parameters

Baud rate	19200 bps
Data bits	8
Stop bits	1
Parity	no
Handshaking	no

Commands to the 8 IN/OUT board must end with a “carriage return”. In computing, the carriage return (CR) hexadecimal 0D or decimal 13, is one of the control characters in ASCII code. The 8 channel digital IN/OUT module detects a byte with the value #13 ($0D) as command end.

Example: READ_IN_ALL$0D
All data from the 8 channel digital IN/OUT module ends with a “carriage return” and “line feed” (CRLF = Enter). This way you can detect the end of the data. When you receive the bytes $0D$0A all data has been received and the data can be processed.
The communication from and to the 8 IN/OUT board can be tested with a terminal program.
For each executed command, the 8 IN/OUT board controller sends an answer frame.
Note that there must be minimum 5ms interval between every two commands !

INPUT functions

READ_IN read status of an input
Value between 1 and 8 which corresponds to the input channel whose status is to be read
Example: “READ_IN 8” read status of input 8
Returns: “READ_IN=n” status of the input
(0 = input is GND, 1 = input is OPEN)
READ_IN_ALL read status of all inputs
Example: “READ_IN_ALL”
Returns: “READ_IN_ALL =n”
- bit 0 = input 1 (0 = input is GND, 1 = input is OPEN)
- bit 1 = input 2 (0 = input is GND, 1 = input is OPEN)
- bit 2 = input 3 (0 = input is GND, 1 = input is OPEN)
- bit 3 = input 4 (0 = input is GND, 1 = input is OPEN)
- bit 4 = input 5 (0 = input is GND, 1 = input is OPEN)
- bit 5 = input 6 (0 = input is GND, 1 = input is OPEN)
- bit 6 = input 7 (0 = input is GND, 1 = input is OPEN)
- bit 7 = input 8 (0 = input is GND, 1 = input is OPEN)

ON_IN_MESSAGE 0|1 automatically send a message if state of input changes, default = 1
“ON_IN_MESSAGE 0” send no message if state of input changes
“ON_IN_MESSAGE 1” send a message if state of input changes
Example: “ON_IN_MESSAGE 0” or “ON_IN_MESSAGE 1”
Returns: “ON_IN_MESSAGE=n”. On Error “ERROR”.

If an input state changes, the board sends a message “IN=n”
This way there is no need to poll the input(s) state!

Ready to use software

You can download a “keystroke edition” of the example software on our website. With the “keystroke edition” it is possible to send keystrokes to an other windows application. This way the other application can be controlled by the inputs of the 8 Channel Digital IN/OUT module!

Just enter the window title of the keystroke receiver and set up the keystrokes you want to send. It is even possible to send mouse events like left, right or middle mouse button click.

The “keystroke edition” can run invisible on Windows boot, working in the background.
Use sndmsg.exe to send commands to the running io8.exe
