I have connected Andor iXon EMCCD 888 with Maxim dl, i have installed drivers in the Maxim dl software directory and Maxim dl can detect the ccd fine. When i click on discover, i see my ccd model number but when i go to "expose" tab, the "readout" is grayed out (Disabled). Please help me how to enable the readout speeds since this ccd has multiple readout rates. Also help me from where can i change the EMCCD's gain values? Thank you.
