*Only 24V is provided on the breakout board. Any other voltage must be supplied.
**Commons must be supplied externally. If the commons are using the Apollo I power supply, each output can only
source 125mA.
2.1 Mounting
The Apollo I has four 0.16 inch mounting holes as shown below.
Figure 2 Apollo I Mounting Holes
You can mount the breakout board on any solid surface that will be protected from dust and dirt. Make sure to use 3/8
to 1/2 inch standoffs so the bottom of the board will not short out. Place the Apollo I as close to the control as possible.
If the parallel port cables are longer than 12” then you may have issues with electrical noise.
2.2 Supply Power
To turn on the Apollo I you must supply 24VDC. The power connection is located at the top right of the board as shown
below.
Figure 3 24V Power Connector
When 24VDC is supplied, the top orange LED labeled Power will turn on. Near the middle of the board another power
LED should turn on as shown below.
2. Installation
Figure 4 Second Power LED
2.3 Configuring Jumpers
On the Apollo I there are four jumpers that must be set up for it to function properly. As shown below, place all of the
jumpers on the top two pins.
Figure 5 Jumper Configuration
The only jumper you that you should ever use is the CP jumper. It overrides the enable circuit and should only be used
for testing purposes. When the CP jumper is connected to the bottom two pins, the green and blue enable LEDs should
turn on (See Hardware Enable and Drive Enable Sections). Otherwise, the Apollo I is not working correctly.
3.1 Setting up Your Parallel Ports
To connect to the Apollo I, you must have two parallel ports on your computer. Port 1 is on the left and port 2 is on the
right as shown below. Connect them both to the parallel ports on your computer.
3. Apollo I Overview
Figure 6 Parallel Port Connections
Now you need to find your port addresses for ports 1 and 2. Follow the procedure below.
1. Click on Window’s Start button, right click on Computer (or My Computer for Windows XP), and select
Properties.
2. Near the top select the Device Manager. (For Windows XP click on the Hardware tab first.)
3. Expand the Ports (COM & LPT) to see all the parallel ports on your control. For all MachMotion controls PCI
ECP Parallel Ports (LPT2) and PCI ECP Parallel Ports (LPT3) are used for the Apollo I.
Figure 7 Parallel Ports
1. Double click on one of the ports and then select the Resource tab. The first number in the first line of the
range is your port address.
Figure 8 Parallel Port Address
For example, in the figure above, the port address is 0378. Repeat step 4 for the second parallel port.
Now you are ready to load the addresses you found into Mach3. After opening up Mach3, select Config, then Ports
and Pins. Enter in your addresses under Port #1 and Port #2. Delete everything in the address but the “0x”. Then
add your addresses to the end of “0x”. In the example above the port address should be 0x378.
Figure 9 Mach3 Parallel Port Addresses
Press Apply and then OK.
If you used a default XML from MachMotion’s website, your parallel ports should now be set up. Press the Reset button
in Mach3 if it is flashing. The enable LED shown in Figure 14 should be on. Otherwise swap your parallel ports on the
control.
The Apollo I has a hardware and drive enable circuit which turns on when Mach3 turns on the Charge Pump signal.
However, before anything on the Apollo I will work, you must connect the two Emergency Stop terminals. Use the table
below as a quick reference for the different signals.

4. Setting up Your Enable Circuit
Table 1 Enable Circuits
Note: If you are using a MachMotion XML or if you purchased a control from MachMotion, both the E-Stop and the
Enable circuits will be set up inside the software.
Emergency Stop
The emergency stop connector is located right below the power connector on the Apollo I. When the emergency stop
terminals are connected together, the red E-Stop LED turns on and the breakout board can then enable.
Figure 10 Emergency Stop Connection
Note: Nothing will work on the Apollo I Breakout Board unless the Emergency Stop terminals are connected together!
Emergency stop input is set up inside Mach3 by setting the EStop signal to port 2 pin 15. Set the Active Low column
to a red X. If it is setup correctly, Mach3 will reset any time the emergency stop terminals are disconnected.
Figure 11 Mach3 EStop Setup
Note: For more information see Configuring Your Inputs section.
4.1 Hardware Enable
WARNING
Do NOT connect 115VAC to any part of the Apollo I Breakout Board. It could cause serious damage to your
board.
The hardware enable is the main enable circuit. It enables all the components on the Apollo I, turns on the 5V enable
(5EN) and the 24V enable signals (24EN), and activates the hardware enable relay (HEN). When the hardware enable
is set up correctly, it will only activate when there are no emergency conditions. Tripping the emergency circuit or a
limit switch will disable the hardware enable. Remember that the emergency stop terminals must be connected for
anything to enable.
The 5V and 24V enable signals can be used for any low current applications. The hardware enable relay can be used
for higher current applications if you supply the voltage source. The signals are labeled 5EN, 24EN, and HEN on the
Apollo I terminal block TB2 as shown below.
Figure 12 Hardware Enable Signals
View the diagram below for an example of the hardware enable relay.
Figure 13 Hardware Enable Relay Example
The green LEDs (labeled Enable) turn on as soon as the breakout board detects the enable signal from Mach3. The
LEDs do not mean that the hardware enable circuit is activated. The hardware enable circuit is only activated when the
red (E-Stop) LED is on.
Figure 14 Hardware Enable LEDs
Hardware enable is set up inside Mach3 by setting the Charge Pump signal to port 2 pin 17 as shown below. Set the
Active Low column to a red X.
Figure 15 Mach3 Charge Pump Setup
Note: For more information see Configuring Your Outputs section.
Note: The Charge Pump also turns on the Drive Enable.
4.2 Drive Enable
Drive enable is used to enable all your drives. When activated, the drive enable relay connects the external enable
(EXT) to the servo enable (SOV) terminals on TB2. The signal SOV runs to each axis control mod jack (See Table 2
Axis Control Mod Jack Pinouts). You can jumper EXT to 5V, 24V, GND, or any other DC voltage for different enable
signals depending on what your servo drives require. Again, remember that the emergency stop terminals must be
connected for anything to enable.
Figure 16 Drive Enable Signals
The Mitsubishi, Yaskawa, and TECO servo drives from MachMotion are all enabled with a ground signal. Therefore EXT
and GND are connected together as shown below.
Figure 17 Drive Enable Example
The blue LED (labeled Drive Enable) on the top middle of the breakout board turns on as soon as the drive enable
signal from Mach3 is detected. The blue LED does not mean that the drive enable relay is activated. The drive enable
relay is only activated when the red (E-Stop), green (Enable), and blue (Drive Enable) LEDs are on.
Figure 18 Drive Enable LED
If you need to use the drive enable signal without using the axis control cables, just connect your signal directly to SOV.
Drive enable uses the same output as the hardware enable. See Figure 15 for the Charge Pump setup.
Now all the LEDs on the Apollo I (besides the inputs and outputs) should be on. If not, go back and make sure that you
set up everything correctly. If all the LEDs are on, you are ready to begin setting up your axes.
To set up your axes you must connect your drives and set up the Mach3 software.
5.1 Connecting Your Drives
The Apollo I Breakout Board uses step and direction to control your axes. You can use differential or single-ended
outputs. For differential outputs you have two signals for step (step + and step -) and two signals for direction
(direction + and direction -). For single-ended you only have one signal for both step and direction. All MachMotion
