For remote operation of this feature it is only necessary to connect pin 7 to ground. The state of this pin is only monitored on removal of the internal reset to the drive after power has been applied to the drive. P4 Parity ---------- 9-10 CLOSED Enable parity When a jumper is connected across pins 9 and 10, the drive will enable parity checking. The use of this jumper excludes the enabling/ disabling of parity by the use of the MODE SELECT command. For remote operation of this feature it is only necessary to connect pin 9 to ground. ********************************************************************** I N S T A L L ********************************************************************** RODIME RO3059/3089/3129/3199/3259-T PRODUCT SPECIFICATION PRO 00220 Notes on Installation ===================== Drive Mounting and Installation ------------------------------- When installing the drive into an enclosure, the breather holes on the drive top cover must not be obstructed. At least 0.1 inch clearance must be provided between the top cover and the host frame. There must be at least 0.1 inch clearance between the drive housing and the host frame to ensure functional vibration isolation. The drive may be mounted in any orientation and is supplied complete with threaded mounting bracket. The drive is mounted using 6/32 UNC screws with maximum engagement of 0.25 inch. The drive installation must provide adequate air flow to ensure that the maximum casting temperature of the head/disk assembly does not exceed 60*C. Physical Description -------------------- SCSI devices are daisy-chained together using a common cable. Both ends of the cable are terminated. All signals are common between SCSI devices. The RO 3000T uses single-ended drivers and receivers, which allow a maximum cable length of six metres. Cable Requirements ------------------ A 50-conductor flat cable or 25-signal twisted-pair cable shall be used. The maximum cable length shall be 6.0 metres (19.8 ft). A stub length of no more than 0.1 metres (3.94 in) is allowed off the mainline interconnect within any connected equipment. A minimum conductor size of 28 AWG shall be employed to minimize noise effects and ensure proper distribution of optional terminator power. Connector Requirements ---------------------- The drive connector is a 50-conductor connector consisting of two rows of 25 male pins with adjacent pins 2.54 mm (0.1 in) apart. The cable connector shall be a 50-conductor connector consisting of two rows of 25 female contacts with adjacent contacts 2.54 mm (0.1 in) apart. The 3M P/N 3425-300 cable connector is recommended. The power connector is a 4 pin AMP Mate-N-Lock P/N 350211-1 (or equivalent) mounted on the reserve side of the PCB. The recommended mating connector is AMP P/N 1-480424-0 (or equivalent) socket housing using AMP pin P/N 350078-4 (or equivalent). Electrical Description ---------------------- All assigned signal are terminated with 220 ohms to +5V (nominal) and 330 ohms to ground at each end of the cable. All signals use open- collector drivers. The terminators are removable. Output Characteristics ---------------------- Each signal driven by the RO 3000T has the following output characteristics when measured at the drive's connector: Signal assertion = 0.0 volts dc to 0.4 volts dc. Minimum driver output capacity = 48 milliamps (sinking) at 0.5 volts dc. Signal negation = 2.5 volts dc to 5.25 volts dc. Input Characteristics --------------------- Each signal received by the RO 3000T shall have the following input characteristics when measured at the drive's connector: Signal true = 0.0 volts dc to 0.8 volts dc. Maximum toatl input load = -0.4 milliamp at 0.4 volts dc. Signal false = 2.0 volts dc to 5.25 volts dc. Minimum input hysteresis = 0.2 volts dc. Terminator Power (Optional) --------------------------- The RO 3000T is configured to supply terminator power,(TERMPWR), with the following characteristics: VTERM = 4.0 volts dc to 5.25 volts dc. 800 milliamps minimum source drive capability. 1.0 milliamp maximum sink capability. SCSI Bus -------- Communication on the SCSI bus is allowed between only two SCSI devices at any given time. There is a maximum of eight SCSI devices.

During manufacture the drive is formatted using a format control code of 1EH. After this format, the drive allows the initiator access to all physical sectors. The drive is tested in this mode and any defective sectors are entered into a list known as the Primary Defect List or P-List. The P-List is stored in sectors 0 and 10 of the special Maintenance Track. This track is physically Cylinder -2, Head 0 and is NOT part of the logical address space normally available to the user. The P-List can only be altered or erased by reformatting the maintenance track (Command E1H) or re- formatting the entire drive (Command 04H) using format control codes 1EH or 16H. LED Error Codes --------------- Under certain fault conditions, the following error codes will appear on the SELECT LED on the front panel. HEX CODE Definition 01 The drive has detected that the spindle motor speed is out of tolerance ( 10%). 06 After stepping the maximum number of cylinders, the drive could not achieve correct track zero status. 07 The spindle motor did not start at power up. 08 Spindle motor failed initial 1% speed check at power up. 0A No track crossing signal during a seek. 0B No servo data. 0C +12V supply failure. 0D Hardware Interrupt Error. All the above error codes are designatd FATAL, and resetting of the drive can only be accomplished by powering off, then on again. If the drive has a FATAL error, it will switch off power to both the voice coil and spindle motors and flash the fatal error code on the SELECT LED on the front panel. The drive will still respond to commands sent across the SCSI interface, but will not execute any of them except TEST DRIVE READY, INQUIRY or REQUEST SENSE.
