4.0 BOARD DESCRIPTION

User’s Manual Page 3

5.0 SPECIFICATIONS

5.1 Power Requirements

It requires a 5VDC @ 500 milliamps power supply to operate. This power can be taken from the computer’s power supply or USB port. Consider using the A3 – USB Power Cable found under Accessories in the website.

WARNING

Check the polarity and voltage of the external power source and connect the 5VDC and GND. Overvoltage or reverse-polarity power applied to these terminals can cause damage to the board, and/or the power source.

6.0 SELECTION JUMPER

6.1 Input (PULL-UP or PULL-DOWN)

Pins 10,11,12,13 and 15 can be set to pull-up or pull-down by selecting the jumper in the appropriate position.

a. If a pin is pulled down, then it needs a high to make it change states. b. If a pin is pulled up, then it is a ground what will make it change states.

1-2: PULL-DOWN 2-3: PULL-UP

7.0 ESPECIAL FUNCTIONS

7.1 Safety Charge Pump "SCP". (Pin 17)

This board takes advantage of Mach ability to send a specific frequency through one of the pins of the parallel port when the program is in control of the system. CNC machinery can be very dangerous, and you could have a risk of the machine doing something different that what you intend the machine to do if the program loses control

of your system. Mach be can be programmed in a way, so when it is “in control”, it

delivers a 12.5 KHz signal through one of the pins. This card lets you use this signal to work as an On/Off switch for your system, enabling a powerful safety system for your equipment. If you ever had windows crash on you, then this card is for you. The port can also do weird things while the system is coming up, or down.

For Configuring the Charge Pump in Mach X: Use the dialog Config / Ports and pins / Output Signals. Enable the Charge Pump output and configures it as is shown in the Fig. 8 Next, press the apply button.

Fig. 1. Charge Pump configuration

User’s Manual Page 6

Selecting the SCHP operation mode

The Safety Charge Pump can be activated or deactivated depending on the jumper position.

1-2: ON 2-3: OFF

Note: When the Safety Charge Pump is activated, the EN terminal is active and a valid

SCHP signal is present, pin 17 will go high. This high signal can be used to enable other external devices, such as enabling other Breakout Boards, or relays that would enable

servos, VFDs, contactors, etc.

7.2 Enable Pin.

The card must be provided with a 5VDC signal to enable operation. This feature has been added to externally control the status of the outputs. When the enable signal is not present, output signals sent high impedance state. If this function is not required, a jumper can be placed between +5vdc and the EN terminal. It has an internal 4.7kOhm pulldown resistor.

Wiring:

The Parallel Port Interface Card has a very basic design that provides the flexibility you look for on CNC projects.

WARNING: This card must have the power supplied while it is connected to the PC. If power is removed to the card while it is connected to the PC, noise can be introduced to the output lines. This can create a dangerous situation as relays or other devices that might be connected to this card could get activated.

8.2 Pins 1,14,16 and 17 simplified block diagram

Fig. 3 Simplified functional block diagram for outputs 1, 14, 16 and 17.

Note: “Internal Enable” = “External Enable Pin” AND (“SCHP” OR “Bypassed SCHP”)

The “Internal Enable” is the result of an AND Operation between the “External Enable Pin” and the SCHP operation mode selected by the user.

Note: The outputs will be deactivated if the board is not connected to the PC parallel port.

Fig. 8 Wiring diagram to connect NPN proximity sensors with internal pull up resistor.

Some NPN proximity sensor has a pull-up resistor (R1) internally. It is necessary to know its value in order to connect safely the sensor with the BOB. Follow this recommendation:

CALCULATING THE R1 VALUE

Note: Rx is the unknown resistor value.

Where:

is the external power supply voltage

is the voltage across the R resistor

RX = VEX.(R/V) - R (1)

A voltmeter is required to calculate the internal resistor value (Rx). Do the connections as are shown in the figure above and do the calculations using the equation (1).

Note. R value has to be known to do this operation. A 4.7KOhm@1/2W is recommended.
