Drive numbering is effected by drive selector pins which are connected by means of a jumper provided. To identify a drive as number 1, short the pins furthest from the EPROM. All daisy-chained drives should have the line terminator pack removed except for the last drive in the chain. All drives are shipped for single usuage; drive 1 selected and the terminator pack present. Note that in the multiple drive configuration, all the DATA interface lines are radially connected to the host.

There are separate connectors for DATA (MFM code), CONTROL/STATUS and dc POWER. The convention for CONTROL is that a TTL logical zero is true and a TTL logical one is false. Up to four drives may be connected to a host system and each drive is provided with a four pole jumper for selection. The CONTROL lines may be daisy-chained, but the DATA lines must be radially (individually) connected to the host. Control signals for the drive are provided via the 34 pin edge connector (P1/J1). The pins are numbered 1 through 34 with the even pins located on the component side of the board. Pin 2 is located on the end of the board connector farthest away from the DC power connector. A key slot is provided between pins 4 and 6. The recommended mating connector is AMP ribbon connector A/N 88373-3. Radial connection of read/write DATA signals is provided by a 20 pin edge connector (P2/J2). The pins are numbered 1 through 20 with the even pins located on the component side of the board. The recommended mating connector is AMP ribbon connector A/N 88373-6. Power (dc) is provided by a four pin AMP Mate-N-Lock connector P/N 350211-1, mounted on the solder side of the board (P3/J3). The recommended mating connector is AMP P/N 1-480424-0 utilizing AMP pins P/N 350078-4. IBM PC, PC XT and Compatibles ============================= Drive Address Configuration --------------------------- The drive address must be configured as the first or second drive, depending on wether it is being used as drive C: or D:, and what type CONTROL cable is being used. An IBM PC XT or AT cable contains a twisted section which requires both drive addresses to be set as drive 2. Most other cables are "straight thru", so drive 1 becomes C: and drive 2 becomes D:. Drive Terminator ---------------- If the drive is going to be used as drive C: and the only hard drive in system, leave the terminator installed. If the drive is going to be one of two hard drives used, the terminator resistor pack must be removed if is NOT the last drive on the CONTROL cable. Cable Connection ---------------- A single CONTROL cable for all hard disks installed is used in a daisy chain fashion and a 20 conductor DATA cable must be provided for each drive to be installed. The PC should provide a power cable. On all RODIME products, the edge connectors are cut with a key slot that identifies the pin 1 end. This should coincide with pin 1 on the controller connectors. -------------------------------------------------------------------- IBM AT and Compatibles ====================== Drive Address Configuration --------------------------- To install any hard disk drive in an IBM AT, the drive address must be configured as the SECOND drive, regardless of wether it is being used as drive C: or D:. If the drive is going to be used in the AT as drive C:, leave the terminator installed. If the drive is going to be used as drive D:, the terminator pack must be removed. Cable Connection ---------------- The AT provides one of the two necessary cables, the CONTROL cable, in addition to the POWER cable. A 20 conductor, 20 pin "header to edge connector" DATA cable must be provided for each drive to be installed. For drive C:, the 20 pin header labeled J4 on the AT controller should be used. For drive D:, use J3. On all RODIME products, the edge connectors are cut with a key slot that identifies the pin 1 end. This should coincide with pin 1 on the controller J connectors. -------------------------------------------------------------------- Controllers ----------- In general, any controller which will operate the RO 200, RO 200E, RO 350 and RO 3000 Series disk drives will also operate the RO 5000 Series disk drive. However, the controller must be able to set the step interval within the range of 5 us to 15 ms and address up to 1224 cylinders to utilize full capacity. Further information is available from the RODIME or from the controller manufacturers them- seleves. ********************************************************************** F E A T U R E S ********************************************************************** RODIME RO 5065/5090 SER. RIGID DISK DRIVE USER MANUAL PN USM-21550 General Description =================== The RODIME RO 5000 Series disk drives are random access storage devices with three or four rigid 5.25 inch disks used as storage media. One disk surface is dedicated to continuous servo positioning data. High performance and reliability are achieved through the use of a rotary voice-coil positioner and a closed loop servo positioning system. Indicators ---------- One red LED indicator is provided on the facia and is illuminated when the drive is READY and SELECTED. This LED is also used to indicate fault conditions in the drive. During power-on the LED will flash until the drive is READY and will go off if the drive is not SELECTED. If an error condition exists, a fault code will be flashed on the LED. Front Panel Fault Codes ----------------------- In addition to its normal function of indicating READY and SELECTED status, the front panel LED is used to flash error messages should certain fault conditions arise on the drive. A four bit binary code is used (long flash = logical 1, short flash = logical 0) with the most significant bit occuring first: e.g. Short, short, long, short = 2 (0010) +------------+--------------------------------------------------+ | Fault Code | Description | +------------+--------------------------------------------------+ | 01 (0001) | No sync | +------------+--------------------------------------------------+ | 02 (0010) | No Track Zero | +------------+--------------------------------------------------+ | 03 (0011) | Motor speed outside +/- 1% tolerance at end of | | | power-up sequence | +------------+--------------------------------------------------+ | 04 (0100) | Motor speed outside +10%, -5% tolerance in normal| | | operation | +------------+--------------------------------------------------+ | 05 (0101) | Track cross time out / Seek error | +------------+--------------------------------------------------+ | 06 (0110) | STEP received while WRITE GATE is true | +------------+--------------------------------------------------+ | 07 (0111) | WRITE FAULT | +------------+--------------------------------------------------+ | 08 (1000) | Microprocessor self-test fail (RAM) | +------------+--------------------------------------------------+ | 09 (1001) | Microprocessor self-test fail (ROM) | +------------+--------------------------------------------------+ | 10 (1010) | No INDEX | +------------+--------------------------------------------------+ | 11 (1011) | Motor not up to speed | +------------+--------------------------------------------------+ Fault codes 1, 2, 3, 8, 9, 10, and 11 are valid during the intitial power-up sequence of the drive. The remaining codes are valid during normal operation. All fault codes are latched by the processor and the drive must be restarted to clear. Illegal Addresses Map --------------------- Each drive has a label indicating the illegal of defective areas on the disk in bytes from index form. These illegal areas have been identified at the factory and contain a repeatable disk defect of one bit in length or greater. No such illegal address will exist on cylinder 0. Illegal Addresses RO 5065 RO 5090 --------------------------------------- Maximum allowed 30 40 Seek Time, including settling ----------------------------- ramp mode step rate = 5 us Track-to-Track = 5 ms Average = 28 ms Maximum = 55 ms Write Pre-Compensation ---------------------- No Write Precompensation is necessary on the RO 5000 Series disk drives. Low Level Format ---------------- A "Low-Level Format" will be required if the drive has not been used in a DOS environment previously. All new RODIME drives require a low level format.
