Three of these jumpers, E1, E2, and E3, are used to select the drive's SCSI ID, while E4 (installed) disables parity. Jumpers E5 and E6 are used to enable either the spindle synchronization signal, or LED, respect- ively. E4 Parity Jumper ----------------- E4 OPEN Parity check enabled CLOSED Parity check disabled There are three removable terminators: RP1, RP2, and RP3. They can be removed from the drive, if bus termination is provided elsewhere in the system. E5 Spindle Synchronization --------------------------- For use in Disk Arrays, a spindle synchronization feature is provided. Spindle synchronization between drives is accomplished by connecting a cable to J4 on each of the drives. Up to twelve disk drives may be connected, and the method used to implement synchroni- zation does not require a designated master drive. To construct the cable, a 4-conductor ribbon cable and 14-pin dis- placement connector (Molex part number 15-47-3142 or equivalent) are required. Install the required number of connectors on the ribbon cable with the four conductors in pin position 1-4 (pin positions 5-14 are unused). To install the completed cable, connect the 14-pin displacement connector to J4 of each drive. Align pin one of the connector with pin one of J4. Install jumper E5 on each drive to enable spindle synchronization.

Recommended Mounting Configuration ---------------------------------- The Astec disk drives are designed to be used in applications where the units may experience shock and vibrations at greater levels than larger and heavier disk drives. Shock Tolerance Features ------------------------ The features which allow greater shock tolerance are the use of rugged media and shock mounts. To take full advantage of the shock mounts, it is necessary to provide a minimum of 0.1 inch clearance on both the top and sides of the drive. This clearance allows for movement of the drive during accleration. Mechanically Isolated Mounting Points ------------------------------------- Ten base mounting points are provided to the customer. Each mounting point is mechanically isolated from the head/disk assembly. The drive is mounted using 6-32 screws; 1/8" max. insertion for the sides, and 1/4" max. insertion for the bottom. The system integrator should allow ventilation to the drive to ensure reliable drive operation over the operating temperature range. For additional vibration isolation, an external suspension system may be used. Cable Requirements ------------------ A 50-conductor flat cable or 25-conductor twisted pair cable is re- quired. The maximum cable length is 6.0 meters (19.68 ft). The cable characteristic impedance should be 132 ohms 10% with a minimum conductor size of 28 AWG. Connector Requirements ---------------------- The drive connector is a 50-conductor connector which consists of two rows of 25 male pins on 100 mil centers. The cable connector is a 50-conductor non-shielded connector which consists of two rows of 25 female contacts on 100 mil centers. Power Connector --------------- The drive has a 4-pin DC power connector (J3) mounted on the PCB. The recommended mating connector is AMP part number 1-480424-0 utilizing AMP pins (part number 350078-4 or equivalent). Electrical Description ---------------------- The Astec family of drives uses open collector drivers. All assigned signals are terminated with 220 ohms to +5 volts and 330 ohms to ground. The termination resistors are removable for multi-device configurations. Cabling ------- Connect the power cable to J3. Connect the SCSI interface cable to J2. Bus termination is required on the last device of the SCSI bus. Diagnostic Routines ------------------- The microprocessor performs diagnostics upon application of power. If an error is detected, the drive will not come ready. SCSI Termination ---------------- There are three removable terminators; RP1, RP2 and RP3. They can be removed from the drive if bus termination is provided elsewhere in the system. Magnetic Field -------------- The disk drive will meet its specified performance while operating in the presense of an externally produced magnetic field under the following conditions. +------------------+------------------+ |Frequency | Field Intensity| +------------------+------------------+ | 0 to 700 Khz | 6 gauss maximum| | 700Khz to 1.5Mhz | 1 gauss maximum| +------------------+------------------+ Acoustic Noise -------------- The sound pressure level will not exceed 40 dBA at a distance of 1 meter from the drive. ********************************************************************** F E A T U R E S ********************************************************************** CONNER CP3100/CP3180/CP3150 PRODUCT MANUAL REVISION V.2 Key Features ------------ The Conner Peripherals Astec family of 3.5 inch disk drive offers high performance and capacity with low power consumption.
