4.9 Seal Function
The display module with seal, which has sealed key control, is different with one without
seal. When the seal is in opened status, functions are same like normal meters. But when
the seal is in sealed status, some functions of meters, which include parameters blocked
by seal and optional parameters, will be blocked. These parameters can still be accessible
by keys and communication way if they can be accessed before, but in sealed status, these
parameters cannot be modified by keys or communication way any more.
Addresses about seal function are 8AFH and 8B0FH.
Address 8AFH is about parameters blocked by seal, which can be configured by users.
These setting will be valid only when seal is in sealed status.
Address 8B0H is about if seal function is valid. When the dispaly module is normal one,
not connected display module, or the seal module is in invalid sealed status, this address
will show seal is open. When the seal is valid, this address will show sealed status and
corresponding parameters will be blocked.
