# Connecting the OP-25
## USB in
The connection between the PC and the operator panel is established with a USB-A to USB-B cable. The included cable features a locking connector on the operator panel side, this prevents the cable from coming loose unintentionally.
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/WfOC3-ro2RjlIhfK32pv5_photoroom-20231206153635.png" size="20" width="664" height="956" position="flex-start" showCaption="false"}
These locking variants are not universal and should only be bought original.
After inserting the USB B side into the 'USB In' connector, both screws can be turned clockwise to lock the USB to the OP-25 reliably.
## Power
Power is supplied through the USB connection or by an optional [external power supply](https://edingcnc.com/product/power-supply-24v-1a/).
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/xa6UBlL1YBB8yuCGlvZvk_image.png" size="34" width="184" height="346" position="flex-start" caption="External power supply connector" showCaption="true"}
Please note, that if power is supplied through the USB connection only two of the four USB interfaces can be used:
The power supply should be 24VDC/1A center positive.
The DC jack plug dimensions are shown below:
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/Mias6FBBY3-eQCWKkhhg9_image.png" size="32" width="800" height="800" position="flex-start" showCaption="false"}
## E-stop output
The E-stop output is controlled by the E-stop button on the front of the OP-25.
When the device is unpowered it will have the same behavior as when the E-stop is pressed. This is done on purpose to ensure the device is ON when using your machine.
The logic for the connections is specified in the table below for your convenience.
| **State** | **Normally open** | **Normally closed** |
| -------------- | ----------------- | ------------------- |
| Unpowered | Closed | Open |
| Powered | Open | Closed |
| E-stop pressed | Closed | Open |
When using the supplied M12 cable, the table below will specify the cable designation. When using aftermarket cables, you will have to measure what wire corresponds to each output. This diagram can also be found on the packaging of the M12 cable.
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/vyao_DQZPDEQ1ynNANlLj_wire-end-m12-cable.png" size="52" width="999" height="421" position="flex-start" caption="Color coding for the included M12 cable" showCaption="true"}
## Relay output
The Relay output is controlled through the Relay button on the front of the device.
This output can only be controlled when the device is connected to the software. In all other cases, the outputs will not deviate from the Normally open/Normally closed designation.
The logic for the connections is specified in the table below for your convenience.
| **State** | **Normally open** | **Normally closed** |
| --------------------------- | ----------------- | ------------------- |
| Unpowered | Open | Closed |
| Powered | Open | Closed |
| Connected | Open | Closed |
| Connected and Relay pressed | Closed | Open |
When using the supplied M12 cable, the table below will specify the cable designation. When using aftermarket cables, you will have to measure what wire corresponds to each output. This diagram can also be found on the packaging of the M12 cable.
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/vyao_DQZPDEQ1ynNANlLj_wire-end-m12-cable.png" size="52" width="999" height="421" position="flex-start" caption="Color coding for the included M12 cable" showCaption="true"}
**The output rating is 24V/1A.** We advise you to use a second power relay if you intend to control anything that could exceed the rating of this relay.
# Using the OP-25
## Starting/stopping/pausing a job
By pressing the **Start **or **Stop **button the machine can be started or stopped executing the current job.
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/mwMrEGZMT3wjwVGePLmJw_start-stop-button.jpg" size="26" width="427" height="571" position="flex-start" showCaption="false"}
Please note, that if a job is running, pressing **Stop **will pause the machine. Pressing the **Start **button again will cause the machine to continue executing the job.
## Controlling the feed override
Another feature of the OP-25 is being able to control the feed rate of your machine. Normally, the appropriate feed rate will have been defined in the G-code of a job. This is considered 100% feed. By using the feed override it is possible to change the percentage of the feed rate.
Overriding the default feed rate is done by the feed override section of the OP-25. The feed override is activated by pressing the 'Feed OV Enable' button. As a result, the indicator on the Feed OV Enable button will light up green.
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/7lRgrLywSP66GrYqzR0i3_image.png" size="70" width="557" height="551" position="flex-start" caption="Feed override disabled (left), feed override enabled (right)" showCaption="true"}
The status of Feed override enable is also visible on the screen. When the feed override is disabled, a dot behind the percentage will appear.
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/xEotKZJMtMH5e2ec4pf5h_image.png" size="52" width="268" height="48" position="flex-start" caption="Enabled feed override" showCaption="true"}
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/oj7tqv7vTE_piQmODzjMA_image.png" size="52" width="268" height="48" position="flex-start" caption="Disabled feed override" showCaption="true"}
While the feed override is enabled, the knob can be turned which will change the feed override percentage. This percentage will be visible on screen
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/ZSXszM5Kos4fKMvWYtMLO_image.png" size="58" width="287" height="107" position="flex-start" showCaption="false"}
Please note, that if the feed rate is set to 0% the machine will stop. To show this the feed rate will be shown in **orange**:
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/vF1QdC_Eizf_TBipLmHVk_image.png" size="58" width="293" height="100" position="flex-start" showCaption="false"}
When the feed override is disabled by pressing the button again, the indicator will turn off and the feed override on the screen is reset to 100%.
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/qzA1RriTKZ4JvhVtmbfPU_image.png" size="52" width="268" height="48" position="flex-start" showCaption="false"}
# Macro programming
The OP-25 features two macro buttons: Macro-1 and Macro-2. These correspond to two user-settable macros. To make use of this functionality, two subroutines need to be added to the macro.
The code below should be added to the macro.cnc file.
:::BlockQuote
sub op25\_1
;OP-25 macro 1 goes here
endsub
sub op25\_2
;OP-25 macro 2 goes here
endsub
:::
The desired commands should go between the `sub...` and `endsub` lines.
To make the Macro-1 button zero the Z axis using a tool setter, for example, the code below can be used. Note that this will perform the zero\_z command, which will need changing based on your physical machine.
:::BlockQuote
sub op25\_1
msg "OP-25 Macro-1 button pressed, Zero-Z will be performed"
gosub zero\_z
endsub
:::
For more information on programming macros, please consult the [software manual](https://docs.edingcnc.com/introduction).
# Firmware upgrade
While firmware updates to the operator panels are rare, they can be necessary for the correct operation of the device with newer versions of the software. The software will notify the user if one such upgrade is needed.
The steps below will instruct on how to perform a firmware update.
Remove power from the operator panel by ensuring the USB cable is removed or the PC is powered off. Also, remove the external power supply if one is used. Press the *Reset *and *MDI *buttons on the front of the device while simultaneously supplying power (either USB or external power). The Feed OV Enable indicator will start blinking slowly. This indicates that the device is ready to receive new firmware. The buttons can now be released.
::Image[]{src="https://api.archbee.com/api/optimize/wP9peVc2bAVBPOh6IboCS/LIs1sGQQRKBSOl6c8nzx4_image.png" size="20" width="267" height="531" position="flex-start" caption="Feed OV Enable blinking indicator" showCaption="true"}

::::Tab{title="Software version 5.00 and above"}
### Start the firmware tool
Navigate to your software installation directory (typically c:\EdingCNC5.xx) and open the bin directory.
Start the FirmwareToolUI.exe program. If this executable is not available, follow the instructions for Software version 4 and below.
### Connecting to a device
Ensure the settings on the top left side of the application are set correctly. For Ethernet devices, the default IP is 172.22.2.100 as filled in by default. Note that this is different from the IP set when [setting up the network interface](https://docs.edingcnc.com/network-setup#oFc-S).
Ensure the device-specific steps have been followed before progressing to the next step.
Connect the device to the PC using the connection method specified in the device-specific steps.
Supply external power if the device is not connected using USB or not powered by the USB port.
Wait for the device to be detected by the application. The device has a short time window in which it can be connected to the application, when this window has passed (typically 5 seconds) the device will boot as normal and can not connect to the application. In that case, disconnect and reconnect the power from the device to try again.
The new device will be listed in the white panel on the left side of the application.
Click the device that needs to be upgraded, this will open the device settings.
By default, the newest firmware file is pre-filled in. When a device is available in both USB and Ethernet, the correct firmware must be selected by the user. When the selected firmware file does not exist, the program button will be disabled (as shown by the grey background color). Ensure that the correct file is selected.
:::hint{type="danger"}
Programming the device with a firmware file that is not designed for it can cause damage to the device. Ensure the (pre-)selected firmware file is correct.
:::
Press the program button to flash the selected firmware to the device. This operation takes roughly three seconds and the result is shown at the bottom of the screen.
