Appendix B • Programming Guide
CMD35 (53h) — Operate Security
_______ UPASn - The 2-hex digits translate to 4-digit decimal.
_______ There is only one security code for all existing ports. All ports have equal access
CMD36 (54h) — Set Audio Parameters
_______ The first time power is applied to the audio board, the following conditions exist:
Extron • Matrix 200 • User's Manual
The Host sends information to modify the status of the security system. The
command has the following subcommands:
Where: SCMD = 80h
81h
82-FFh
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.
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.
to the security system, so a conflict may arise whenever more than one port is
active.
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
No inputs are connected to outputs.
All inputs are set for professional levels.
All outputs are set for consumer levels.
Examples follow.
Request system access (format 1)
Terminate session and lock system (format 2)
