Even though its been years since I've did a lot of work with the R-J boot monitor, I'm sure that you need the software to reload some or all of the operating system and the specific variables needed for your robot and application. IF you can do an INIT Start to recover the software core from the FROM, you will still need the software disks to reload the variables particular to your robot.
- The 3rd picture in the last post shows the first red LED lit on the CPU board. This indicates a CMOS parity error which usually means reloading software.
- There is no extra copy of the software residing in memory somewhere. This is 25+ year old technology, there's only enough memory to run the system - nothing more.
- Pulling the SRAM (CMOS) card would have cleared that memory and dumped the software. This is the memory the battery maintains.
- Clearing the CMOS will write zeros to all CMOS memory locations which will delete the software portion residing in CMOS memory. This is normally done as a prelude to loading software. You will need to reload software after doing this.
- A cold start initializes more variables than the normal warm start. This enables changes usually made in a controlled start and resets buffers & pointers. It's not much help if you can't get to at least a controlled start menu.
Hi Skooter,
I have also similar problem about software. I have 2 pcs R-J2 controller. One of them no problem. I still can use it. But one of them lost system software. It has message "No System Software" on the teach pendant. Both are same and robots are also same. Is it possible to copy all system softwares one to other. Could you please help me how can I do step by step if yes.
Thanks in advance.
