Hi folks, I have a bank of 9 digital readout units. They plug together to make up a 9 digit readout. Each unit is one digit. The kicker is that the second digit has a decimal point. I can't find out how to move it to the 3rd digit. These are Omron A7E-AG21H-DR. They each run to a central digital control card. Also, they plug together which ends up at an end plate. I think the decimal is moved by changing the end plate but can't find any scamatics on this. Anyone ever saw one of these before? I understand if you hadn't. They came from Japan and can't find any paperwork with them. Thanks in advance for any help.
