GPICommander is two things: a USB to GPI Converter and a software. You can send or receive GPI triggers using AppleScript, so it can be used with any macOS application. Since version 2.2, there is also a REST API available so you can send and receive GPI triggers very easily.
If needed, an SDK is available if you want to have direct access to it without AppleScript (it also runs on Windows then and it enables you to control the unit by writing C code.)
It has 24 inputs (open-collector type, common ground) and 8 independant relay outputs but since each unit has a unique serial ID, you can chain more than once on the USB bus to have more inputs and/or outputs.
Download our GPICommander application so you can :
A few of our software have a direct integration with GPICommander (so without having to create AppleScripts). For example:
|Number of inputs||24 on a DB 25 connector (ground on pin 25)|
|Number of outputs||8 on phoenix connector with screw contacts|
|Applications which have direct integration *||GPI Input||GPI Output|
|OnTheAir Video Express|
* If you are using a GPICommander box v3, make sure that your software supports it.
|GPICommander application **||macOS||Windows||Linux|
|Available to download for free||
SDK is available. Contact us if you are a developer and want to control it in your app.
|Control Outputs (puls, on/off) using AppleScripts|
|Trigger AppleScripts when input status changes|
** If you use an application that does not have a direct integration (see above), you can use our application GPICommander, available to download for free, which can be used together with AppleScripts to build an integration.
|1.0 to 2.x|
|Recommended macOS||macOS 10.15.6 or later|
|Recommended RAM||2 GB|
|Recommended Mac||All Mac should be supported.|
|Differences between versions||On May 11th, 2022, we started shipping version 3 of the GPICommander box. This version looks the same and has the same feature as version 2, but uses a different chip, and thus only the software compiled after November 5th, 2021 will be compatible with it. Check the following article for more info on which application supports it.|
|Inputs||24 (DB25) - The inputs are simple "contact closure", they are considered ON when grounded (connected to the ground on pin 25). If you supply voltage to the inputs, you may damage the unit.|
|Outputs||8 (Phoenix) - The outputs are simple independent relays that short (connect) each pair of output connection (1-2, 3-4, 5-6, etc...). The relays accept up to 220V going through them.|
|Maximum voltage on outputs||Check the following specifications.|
|Maximum voltage on inputs||NOT SUPPORTED. Do not enter any voltage, inputs are simple contact closure.|
|Connection to host computer||USB 2.0|
We know that some of our users can not upgrade their macOS very often. This is why Softron tries to maintain compatibility with older versions of macOS as much as possible, but it is not always possible to achieve. Because Operating Systems are usually significantly improved over previous versions, Softron must use many of the more capable built-in functionalities inherent in Apple's latest OS releases. Failing to do so would mean that Softron software would essentially be blocked from using the new Frameworks provided in the OS. For this reason, Softron's free support is provided only on the current and previous macOS versions. Also, most of our tests will be done on these macOS versions, and only basic tests will be done on the previous OS. We will always try to help, but in some cases, the best solution is to upgrade your macOS to a more recent version.
Softron does not warrant that these recommended configurations will always meet specific user requirements. They are intended as guidelines and are based on extensive testing that Softron has done, they can be changed without notice. Hardware, drivers, software and operating systems change regularly and we advise users and prospective users to evaluate their requirements in their specific environment/workflow using Softron demo licenses that are available for downloading from Softron's web site.
Version 3 - 11 May 2022
Once downloaded, unzip the file, and run the installer. Connect your GPICommander box to your Mac in USB, then start the GPICommander application, and you should be able to control it.
The GPICommander application is a free application to use with the GPICommander box.
Just download the latest version and replace your previous version. It is always recommended to run extensive tests with your specific workflow and setup before putting a new version in production. You can use a free demo version for that on a separate computer. Previous legacy versions are available from the general downloads page.
