This is a 2400 IPX, I have 5 DTerm series E stations with DCU-60-1 add on modules. 3 of them program & work just fine. Two of them give an error when you program the AKYD but seem to work. the error: "IMG Multi Line or PS appearance on Dterm data Invalidity(Package is not support). (Error 0x0249)" does anyone know what this Jinglish means??? All 5 stations are on the same type of card (16ELCJ-B) with the same software (SP3514 B7A)IPX is R-11. I would hate for this error to cause some other problem somewhere else. My cohort programmed a Dterm & add on module to wrong Lens pairs and it caused a station on the card to always go to voicemail. (I found that one) but these other two look OK.
