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, 80h, 80h, 04h
Where: SCMD = 080h = send status bytes
81h-8Fh = reserved
Response: CMDØ, SCMD, Erc, Status1, Status2, Status3, 80h, 80h, 04h
Format: 30h, 80h, Erc, StsB1, StsB2, StsB3, 80h, 80h, 04h
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 0 H-Sec 0 Ps
Where: StsB2, Bit 0 – Power Supply in use - 0 = Backup Power; 1 = Main
Power
StsB2, Bit 2 – Hardware Security status - 0 = locked; 1 = unlocked
(available to user, when unlocked)
StsB2, Bits 1 and 3-6 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 Bit-1 thru 6 are reserved (should be zero)
