# iProFiler Server — Update v2.6.1

## What's New

### Support for Up to 24 GPIO Switch Inputs

Previous versions of iProFiler supported up to **8 GPIO switch inputs** for
controlling recording. Starting with v2.6.1, this limit has been raised to **24
inputs**, giving you far greater flexibility when working with larger GPIO hardware
configurations.

#### What this means for you

- Archives can now be triggered by any of up to 24 switch inputs, depending on your
  hardware.
- The **Skim Switches** section on the *Record* tab of the Archive Options dialog
  still shows 8 switches at a time. Use the new **[>>]** button in the upper-right
  corner of that group to step through the three banks of switches:
  - **Bank 1** — Inputs 1–8
  - **Bank 2** — Inputs 9–16
  - **Bank 3** — Inputs 17–24
- Select the desired inputs in any bank (or across multiple banks) as you normally
  would. Your selections are remembered across all three banks.

#### Compatibility

- Existing archives configured with 8 or fewer switch inputs will continue to work
  without any changes.
- This feature requires GPIO hardware that supports more than 8 inputs. If your
  hardware provides 8 or fewer inputs, the extra banks will simply appear disabled.

## Installing the Update

The update consists of two files: `ProFilerServer.exe` and `ProfilerGPIO.dll`. Please follow these steps to update your iProFiler installation:

1. Stop the `ProFilerServer` application if already running.
2. Locate the installation directory for the iProFiler application.
3. Create backup copies of `ProFilerServer.exe` and `ProFilerGPIO.dll` that already exist in that folder. The backup copies will allow you to revert to the previous version in case the update does not work as you expect.
4. Replace the existing `ProFilerServer.exe` and `ProFilerGPIO.dll` with the versions included with this update.
5. Restart `ProFilerServer.exe`. The version string in the title bar should show v2.6.1, or later.
6. Verify that your configuration is still okay, especially in regards to skim switch selection.
7. Start the archive recording.
