The remainder of this appendix explains the operation of each command
including data byte breakdown, responses and possible error codes.
The Host asks the Matrix for its status settings.
Format: CMD0, SCMD, Cks1, Cks2, EOT
Where: SCMD = 080h
81h-8Fh
Response: SCMD = 080h — send status bytes
Format: 30h, 80h, Erc, StsB1, StsB2, StsB3, Cks1, Cks2, EOT
Status Bytes (StsB1-3) are described below.

Bit usage: 1 Prg
Where: StsB1, Bit 0 Power On/Off status — 0 = powered on;
StsB1, Bit 1 Backup battery status — 0 = battery okay;
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
StsB1, Bit 5 Sequence running — 0 = not running; 1 = running
StsB1, Bit 6 Program status — 0 = no program event pending;
