DECM4 sync problem on 4200e 3.0
Posted: 02 Apr 2019 16:17
Hi
I'm trying to make this old unit to work and it seems to be ok, but this DECM4 board is unhappy and just keeps the red led lit. AC board has the X4 jumper installed and still no luck. I do not have CKIBS or a board to mount it. What i have is this: CM, AC, DLC8 (3boards), SOTO4, SLC8 (2boards), T2 (but no landline here anymore).
Do I have any way to get the sync going or do i need to get this upgraded to 4.0 ?
Old system but I have a use for this for a while.
(would anyone happen to have the 4.x eproms copied to a file as i do have a eprom programmer?)
Thanks for any opinions or instructions.
