Hi All,

I aquired two Philips series 2500 DRO's (one double and one triple axes) with PE2580 heads.

I have tried to find information on these older DRO's but that is very limited. Is there somebody out there that can help me understanding how to use these DRO's? I am not sure if they are defect or that the memory that holds the information of possible various heads that can be used is gone or something.

I do get an "Error 56" on one of the DROs and a Generic "ERROR" on X/Y/Z axes on the other. I do have the correct manual for these 2 DROs.

Any hellp is greatly appriciated

Thanks!
