This problem is persisting.
I've tried to single out each RS232 option. there's 1, 2 and 3. according to the information that I have gathered,
1: connector CD1 on the CRT pcb (in the pendant)
2: connector CD1 on the master pcb
3: connector CD2 on an RS232 option pcb
my lathe doesn't have any option PCBs so it's not option 3, option 1 doesnt seem to exist, there's no connector on my crt like a honda connector for example that looks to do serial. The RS232 port on the side of the pendant is wired up to the master PCB, so its got to be option 2.
according to the mori seiki manual that I have, option 2 is the default parameter setting for the SL0 and is set to params 0020 to 0023. So, these things make sense in terms of documentation.
The other RS232 parameters are for configuring are 5001-5013 the device No., not too clear on what this means but i think its just pointing to which set of params to read from
parameters 5110 to 5162 Spec. No. (which says to use control codes, and if feed is punched), number of stop bits, and the baud rate, in sets of three like (5110 Spec No., 5111 Sopt Bits, 5112 Baud Rate), there are sets of 3 for 6 device no.'s
I have 0020-0023 set to option 2, 5001 set to 0, 5002, set to 1, 5003 set to 0, 5110 set to 3, 5111 to 2, 5112 to 10. this is the logical setup and it correlates to the default params from the mori seiki manual, but it doesnt work, still gives SR807 under all conditions or attempts to read or punch.
Its almost got to be a messed up 9000 parameter. for example, if i wanted to buy and install an RS232 option board, id put that board in, but how does the control know that I did it?? ok, so is there are parameter to enable RS232 from the main pcb also? it seems crazy, you have to be able to load data on and off as standard.
