cc and dd are two-digit numbers.
"aa" is the value read from the parallel GPI port on the rear panel, as
described in chapter 3.
"bb" is the revision level of the "IO PLD". At the time of writing, the current
revision level is "03".
"cc" is the revision level of the "CORE PLD". At the time of writing, the
current revision level is "01".
"dd" is the revision level of the "8058 PLD". At the time of writing, the
current revision level is "01". If this has a value of "00" or there is no value
displayed at all, the caption encoder has an 8038 submodule, not an 8058
submodule. Caption encoders containing an 8038 submodule cannot be
upgraded to an 8058 submodule.
