Extron Serial Control of Legacy Unison

Anyone have any experience with programing extron controllers connected to a legacy unison controller? I'm trying to get the code to work. Its a simple code that basically is asking for "room," "resource," and "preset." resource may be the wrong word now that I think about it. Anyways based off f what I se in the unison controller my room is "Auditorium" and from my understanding I don't need a resource. However if I do I believe it to be "Zone 1". Then Preset I thin k is just a number, but I have also tried "Preset 1.

From a wiring stand point I have a 2 conductors wire with a ground. I'm using red as TX and Black at RX and then the ground as common. On the DB9 it is wired to Pint 2 TX, Pin 3 RX, and 5 common. I did not change this as this was originally connected to a creation controller. DO I need to move the TX to pin 1?

Thanks for any input that can be given.

Hi I hope I can help you. What you are referring to is Unison Serial Access Protocol. This is an RS232-based communication protocol that allows you to send commands to a Unison Legacy system from any RS232 controller. It required a specific language and wrapper to work, AND you need to know the accurate names of your Rooms and Presets inside Unison. Here is a page with information and links to the programming guides.

To get the object names you can either save the configuration to a disk and then send it into wither Technical Suport or to a local ETC dealer to give you this information, OR you can navigate the ARCH menu of the processor to get them.

If looking over this you still have questions, I suggest reaching out to technical support at Service@etcconnect.om. letting them know you are looking to connect your extron system to a Legacy Unison system via USAP. That should give them the right path to assist you.
