Has anyone had any luck with these JMC MCDC706 Brush DC drives? They are all over Ebay, Amazon, Aliexpress and elsewhere. They are cheap. They have an Alarm output function. I bought 3 of them. But I can not get them to communicate to any tuning software via RJ11 to DB9-RS232. RS232 has 2 different pinouts and I tried both. I also tried USB to DB9 (serial) converter cable. I can Get DCS810 drives to Communicate fine.
Any ideas would be helpful.
Russ.
