keyword=access work to replace the scaler 2d (NIM-ELE3) (late entry)
We first changed the address of the new scaler to be the same as the
previous old one, and then we run the coda and xscaler to check the data.
We can read the data from the xscaler as well as the raw data file, but
the rate it shows are several 10^8 HZ in all of the channels in that
scalerm, and Dianchen mentioned that it might be because the current
scaler are working in the different bit reading mode than before. So we
compared the three jumpers right below the addressing knob. The previous
scaler only has the middle jumper connected with the other two on the
side open. We adjusted the new scaler the same way. After that, we are
able to read the reasonable data (sync signal)from the xscaler now.
If my memory is correct, the new scaler we are using now has all three
jumpers connected before we change it.
