9 OPTIONAL SA-K97U RS-232C INTERFACE BOARD 4 Others (Input data correction/Error cancellation) These are return codes from the SR-9090U. (Error-related codes only) (1) ERROR (02H) : This is returned when commands of more than 1 byte are transmitted to the VCR and an illegal command is received in the 2nd byte (or later) of the transmitted command. In this status, no command can be accepted and only STATUS SENSE will be returned. To restore normal operation, transmit CLEAR ERROR (41H) or CLEAR (56H) to the VCR. CLEAR ERROR (41H) : Used to cancel previously-transmitted 1-byte numeric data when inputting numeric data such as search point. Also used to cancel error status. CLEAR (56H) : Clears the whole command. Cancels the current status and stops the VCR. Also cancels the error status. Eg : After setting the recording/playback mode to "L24H", 32H is mistakenly transmitted . Cancel 32H with "41H" and input "33H" instead. TXD RXD 7EH 0AH 30H 0AH 32H 0AH 41H 0AH 33H 0AH 40H 0AH Time (2) NAK (0BH) : VCR will return this code when non-defined or non-functional command is received in the 1st byte of the transmitted command. In this case, it is not necessary to input CLEAR. Check whether the transmitted command is acceptable to the VCR or not. 3 Commands reference chart VCR control commands Page OPERATE ON/OFF PLAY/REV PLAY STOP FF/REW TIMER ON/OFF OPE ON/OFF EJECT F-FIELD STEP R-FIELD STEP REC CHECK REC/REC PAUSE VISS FWD/REV VISS SEARCH 58 58 58 58 58 58 58 58 58 58 58 58 59 5 Recording/playback mode MODE SHIFT MODE 5 Timelapse VCR operation mode TL STATUS SET 5 Date and time setting DATE SET TIME SET 5 Timer programming PRG/CLK SHIFT -/+ SET -/+ CANCEL 5 On-screen setting ON SCREEN ON/OFF ON SCREEN SELECT POS V+ POS H+ 5 Others AL/PL RESET COUNT RESET Commands for VCR status verification Page COUNT CODE DEVICE TYPE VTR INQ PL/AL COUNT SENSE HOUR METER SENSE TL STATUS SENSE STATUS SENSE DATE SENSE TIME SENSE 61 61 61 61 61 61 62 61 61 Byte returned from VCR 4 bytes 4 bytes 1 byte 6 bytes 4 bytes 6 bytes 5 bytes 6 bytes 6 bytes Others Page JVC TABLE 1 ON/OFF 58 Return codes from VCR Page ACK NAK ERROR CASSETTE OUT COMPLETION NOT TARGET ALARM INPUT 58 63 63 58 58 58 62 VCR setting commands Page 59 59 59 59 59 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 63
