Since the implementation of the Orban standard, some digital STLs were
released that misinterpret these status bits. Some respond to the AES/EBU
emphasis bits (110) by applying an EIAJ (50/15uS) shelving de-emphasis.
This will cause an audible (10.5 dB) loss of high frequencies. Version 3.00
software allows the user to enable- or disable the Orban implementation of
status bits. When disabled, the 8200 sends status bits identifying that
emphasis is "not indicated," which ensures that the affected digital STLs will
not inappropriately apply EIAJ de-emphasis.
When these digital STLs are used in combination with an 8200 and 8218 (or
8208), DO STATUS ENABLE must be set to No, and the 8218 (or 8208),
cannot utilize the "AES determines emphasis" feature.

PC Security Enable

[On] or [Off]
The OPTIMOD 8200 with software Version 3.00 or higher, can be
controlled with a computer utilizing RS-232 and the Orban supplied 8200PC
software for Microsoft Windows, or through binary commands.
The Orban 8200PC software offers full access to all 8200 features, while the
binary communications method can only recall presets.
When set to On (default), this control allows remote control of the 8200
through RS-232 communications, only with the Orban supplied 8200PC
software for Microsoft Windows. Access to the 8200 is the same as under
Version 1.2x.
When set to Off, this mode disables all password protection entirely. PC
access using binary commands is allowed for recalling presets only.
Complete control by 8200PC is still allowed, however password protection is
