Topic: ADI-6432 RS-232 embedding for HA-remote of Yamaha AD8HR Mic-preamps
Hello.
I am using an RME ADI-6432 + Micstacy (plus 3 Mackie Onyx 800R 8-channel Mic Pre-amps) for remote recording duties linked to an HDSPe MadiFace (attached to a Lenovo T520). I am now doing a little more of this work and require the ability to remotely control my Mic-Preamps from a distance. I have therefore recently expanded my channel count using a number of Yamaha AD8HR Mic-preamps and would like to replace my Mackie 800R's with these Yamaha Mic-preamps due to their ability to be remote controlled from afar (just like the Micstacy).
All functions of the Yamaha AD8HR mic-pres are remote controllable using the Yamaha HA-Remote protocol. This is most often achieved using a Yamaha Digital Mixing desk (which I don't own) via the desks RS-232/422 port, however it is also possible to use standalone PC software to achieve these remote control functions (YamMon software produced by LightViper, now distributed by FiberPlex). I have used this software successfully by using a USB to RS-232 converter cable and attaching it directly to the Yamaha Mic-preamps using a Null-modem cable.
This standalone software works flawlessly however it requires the initial selection of a COM port (which is achieved by the virtual com-port driver of the USB to RS-232 converter) before it will function. I am not sure if this is a simple hand-shake protocol to confirm that there is something at the other end, or something more involved.
How does one access the RS-232 port of the ADI-6432 via software in order to transmit commands to it? I would basically like to send the HA-Remote-control commands from my YamMon software through the ADI-6432 to the Yamaha AD8HR's. How does one normally access and use the RS-232 port of the ADI-6432? Specifically, how does one transmit data to the RS-232 port, via the MadiFace or Madi HSDP card? There doesn't seem to be much guidance in the manual and I have no idea how to proceed from here?
I have checked and confirmed that the ADI-6432 is not configured for AES Transparent mode, therefore the transmission of serial data should not be blocked.
Is there anyone familiar with RS-232 use & signalling and if so, is there any advice you could pass on? Could it be an issue with the initial hand-shaking that does not allow the software to find the RS-232 Com port and therefore allow use of the YamMon software. As I am largely unfamiliar with these protocols and pin assignments I'm not sure if it merely a wiring issue or a fundamental incompatibility?
For reference, here are the respective pin-outs of the DB9 RS-232 ports:
