Recommended diseqc switch for DM800sev2

  • Hello,
    I am having difficult getting a 2 way diseqc switch from Smart Electronics to work on my newly acquired DM800sev2. This is an original box without any modification. The switch works as it was working previously with another box. It also works on this box although not very reliably. Sometimes I can get it to switch and sometimes it does not switch at all. I tried both the simple configuration and various advanced configurations.
    Are there any known issues with this switch on this particular box? Is there a more appropriate switch for this box? What are the correct settings to get this switch working on this box?
    Many thanks
