CMD35 (53h) — Operate Security
The Host sends information to modify the status of the security system. The
command has the following subcommands:
Where: SCMD =
80h Request system access (format 1)
81h Terminate session and lock system (format 2)
82-FFh reserved
Format 1: CMD35, 80h, UPas1, UPas2, Cks1, Cks2, EOT
Where: UPas1 and UPas2 are user-entered security codes that must match
internally stored MPas1 and MPas2 to gain access to the system. If they
match, the security status bit (StsB3, bit-0) will be set accepting all
subsequent commands.
_______ UPASn - The 2-hex digits translate to 4-digit decimal.
Security code 80h = 00dec and E3 = 99dec. See conversion table on page B-2.
Response : CMD35, 80h, Erc, Cks1, Cks2, EOT
Possible Ercs: D2 = No passcode assigned
Format 2: CMD35, 81h, Cks1, Cks2, EOT
Terminate the session and lock the system.
_______ There is only one security code for all existing ports. All ports have equal access
to the security system, so a conflict may arise whenever more than one port is
active.
CMD36 (54h) — Set Audio Parameters
The host tells the Matrix how to set all eight inputs or outputs of the audio board
performance features, such as gain/attenuation and channel configuration. The
command must include data for all eight inputs or outputs. The first data string is
for I/O #1, the second for I/O #2, etc.
Format: CMD36, SCMD, {(LGain, RGain, Misc, CR)...}, Cks1, Cks2, EOT
Where: SCMD bits 3-0 = BdAd (board address, or plane #)
bits 7-4 = 8h (1000b) for input settings (INP)
= 9h (1001b) configure output (OUT)
= Ah - Fh (1010 - 1111b) are reserved
Possible Ercs: D4 = No audio board
_______ The first time power is applied to the audio board, the following conditions exist:
No inputs are connected to outputs.
All inputs are set for professional levels.
All outputs are set for consumer levels.
Examples follow.
