Using Commands
The remainder of this appendix explains the operation of each command
including data byte breakdown, responses and possible error codes.
CMD0 (30h) — Send Status
The Host asks the Matrix for its status settings.
Format: CMD0, SCMD, Cks1, Cks2, EOT
Where: SCMD = 080h send status bytes
81h-8Fh reserved
Response: SCMD = 080h — send status bytes
Format: 30h, 80h, Erc, StsB1, StsB2, StsB3, Cks1, Cks2, EOT
Status Bytes (StsB1-3) are described below.
Status Byte 1: 7 6 5 4 3 2 1 0
Bit usage: 1 Prg Seq Slv Ver Gnlk Batt Pwr
Where: StsB1, Bit 0 Power On/Off status — 0 = powered on;
1 = powered off
StsB1, Bit 1 Backup battery status — 0 = battery okay;
1 = battery low
StsB1, Bit 2 Genlock Signal — 0 = detected; 1 = not detected
StsB1, Bit 3 Vertical interval switching — 0 = disabled; 1 = enabled
StsB1, Bit 4 Slave status — 0 = stand alone unit or master controller
1 = slave in a compound matrix
StsB1, Bit 5 Sequence running — 0 = not running; 1 = running
StsB1, Bit 6 Program status — 0 = no program event pending;
1 = program event pending
(timer is set)
Status Byte 2: 7 6 5 4 3 2 1 0
Bit usage: 1 0 0 0 Cksm H-Sec Exec Ps
Where: StsB2, Bit 0 Power Supply in use — 0 = Backup Power;
1 = Main Power
StsB2, Bit 1 Executive mode status — 0 = Executive mode Off;
1 = Executive mode On
StsB2, Bit 2 Hardware Security status — 0 = locked; 1 = unlocked
(available to user, when unlocked)
StsB2, Bit 3 Checksum status — 0 = Checksum enabled
1 = Checksum disabled
StsB2, Bits 4-6 are reserved (should be zero)
Status Byte 3: 7 6 5 4 3 2 1 0
Bit usage: 1 0 0 0 0 0 0 S-Sec
Where: StsB3, Bit 0 Software Security status — 0 = locked; 1 = unlocked
(available to user, when unlocked)
StsB3, Bits 1 thru 6 are reserved (should be zero)
