Zaxcom QRX235
Thank you Ulrich,
Still no luck with the QRX235. It looks like the problem is on the QRX235 side, as I was able to jam the Tentacle from a Zaxcom ERX3TDC without any issue (setting the TC output to 0.5 Volts). At any rate, that achieved what I needed, so it’s all fine for the time being.
Best,
Simon
