Where can I get a PC/DSP-X00 Controller? (X representing the number of axes 1-8)
PC/DSPs are obsolete and no longer available. However, the PCX/DSP was designed as a drop in replacement for the PC/DSP model (see below).
Can I use a PCX/DSP Controller as a drop in replacement for PC/DSP in my application?
Yes, if you are currently using MEI software version 2.1C or later and are not using Micro-stepping in your application. If you are using micro-stepping or a version of the software earlier than 2.1C, you can contact RSI to explore your options.
Why is Config failing to download firmware onto my PCX/DSP Controller?
If you have Software version 2.1C, you should request a copy of the 2.1C1 Config. While 2.1C works properly during execution, the Config program needs to be replaced.
