The 2217D, 2210D, 2207D, and 2205D have three ID jumpers ID0, ID1, and ID2. The jumpers are used to assign one of eight SCSI ID bits (0-7) to the drive. In multiple-device systems, each drive must have its own unique ID. Interface Termination --------------------- EXTERNAL terminator only. The interface terminator provides proper termination for the inter- face lines and must be installed on the last device on the interface. For the differential drives, Micropolis recommends the use of an IN LINE TERMINATOR. The IN LINE TERMINATOR may be installed between the drive connector and the ribbon cable (Option 1), or the IN LINE TERMINATOR may be installed in the last plug on the ribbon cable (Option 2) .

The drives are designed such that the outer frame should be hard- mounted to th ehost equipment; no additional/external shock mounts should be used. Recommend orientation is vertical on either side, or horizontal with the Device Electronics board down; other mounting orientations may be used. No matter what mounting orientation is used, Micropolis specifies that the maximum HDA casting temperature not exceed 60*C (140*F). If the HDA casting temperature measurement cannot be made, the ambient air temperature around the drive must be kept at or below 50*C (122*F). Caution: The mounting screws must be selected so that they do not penetrate the bottom mounting holes by more than 0.20 inches or the side mount- ing holes by more than 0.156 inches. Screws that are too long will short to PCBA components and/or prevent proper operation of the shock mount system. Mounting holes -------------- 3 per side and 4 on bottom #6-32 UNC-2B thru.

For active termination, the assigned signals are terminated with 110 ohms to +2.85V (nominal). For passive termination, the assigned signals are terminated with 220 ohms to +5V (nominal) and 330 ohms to ground. All signals use open-collector or three-state drivers. Single-ended drivers and receivers allow a maximum cable length of six meters (primarily for connection within a cabinet). Signal transmission requires a single 50-conductor (flat or twisted pair) cable. A characteristic impedance of 100 ( 10%) ohms is recommended. a. Input Characteristics Each of the drive's signal receivers has the following characteristics when measured at the interface connector. 1) Low-level input voltage (Signal true) = 0.0 VDC to 0.8 VDC 2) High-level input voltage (Signal false) = 2.0 VDC to 5.25 VDC 3) Low-level input current = -0.4 milliamps at 0.5 VDC 4) High-level input current = 0.1 milliamps at 2.7 VDC 5) Minimum input hysteresis = 0.2 VDC 6) Maximum input capacitance = 25 pF b. Output Characteristics Each of the drive's signal drivers has the following characteristics when measured at the interface connector. 1) Low-level input coltage (Signal assertion) = 0.0 VDC to 0.5 VDC 2) High-level input voltage (Signal negation) = 2.5 VDC to 5.25 VDC 3) Minimum driver output capability = 48 milliamps (sinking) at 0.5 VDC. c. Terminator Power (TERMPWR at Pin 26) Terminator Power has the following requirements: V(TERM) = 4.25 VDC to 5.25 VDC 800 milliamps minimum source drive capability, with 1.0 amp recommended current limiting (e.g., a fuse). 1.0-milliamp maximum bus loading (except for the purposes of providing power to an internal terminator). The drive provides keyed connectors to prevent accidental grounding or misconnection of terminator power. DIFFERENTIAL Interface Electrical Characteristics ------------------------------------------------- Differential interface signals consist of two signal lines which are denoted +SIGNAL and -SIGNAL. A signal is defined as true when the +SIGNAL is more positive than the -SIGNAL. A signal is defined as false when the -SIGNAL is more positive than the +SIGNAL. Differential drivers and receivers allow a maximum cable length of 25 meters. Signal transmission requires a single 50-conductor cable. A characteristic impedance of 100 ( 10%) ohms is recommended for un- shielded flat or twisted pair ribbon cable. A minimum conductor size of 28 AWG should be employed to minimize noise effects and ensure proper distribution of optional terminator power. A stub length of no more than 0.2 meters is allowed off the main-line interconnection within any connected equipment. a. Input Characteristics Each of the drive's signal receivers has the following characteristics when measured at the interface connector. I (input current on either input) = 2.0 milliamps, maximum Note: These characteristics include both receivers and passive drivers. This requirement is met with the input voltage varying between -7V and +12V, with power either on or off, and with hysteresis equaling 35 millivolts, minimum. b. Output Characteristics Each driven signal has the following characteristics when measured at the interface connector. VOL (low-level output voltage) = 1.7V maximum at IOL where IOL = 55 milliamps VOH (high-level output voltage) = 2.7V maximum at IOH where IOH = -55 milliamps VOD (differential voltage) = 1.0V minimum, with common-mode voltage ranges from -7 to +12 VOL and VOH are measured between the output terminal and the SCSI device's logic ground reference. c. Terminator Power (TERMPWR at Pins 25 and 26) Terminator Power has the following requirements: V(TERM) = 4.0 VDC to 5.25 VDC 600 milliamps minimum source drive capability, with 1.0 amp recommended current limiting (e.g., a fuse). 1.0-milliamp maximum bus loading (except for the purposes of providing power to an internal terminator). The drive provides keyed connectors to prevent accidental grounding or misconnection of terminator power. Adjustments and Maintenance --------------------------- The drives requires no adjustments or periodic maintenance; additionally, no mechanical adjustments are required to prepare a system for handling or shipment. Field-Replacable Components --------------------------- The concept of repair by replacement of complete functional components is utilized in the drive, resulting in an MTTR of less than 15 minutes. Data Transfers -------------- The drives are capable of transferring data up to 10 MBytes/sec in synchronous mode and 5 MBytes/sec in asynchronous mode. ********************************************************************** F E A T U R E S ********************************************************************** MICROPL. 2217/2210/2207/2205-S/D PRODUCT DESCRIPTION 135861 REV. A The single-ended and differential interface drive is compatible with the "ANSI CCS" and "SCSI-2" versions of the industry-standard Small Computer System Interface (SCSI) specification. Media Defects ------------- Media defects are physical characteristics of the media which result in repetitive read errors when a functional drive is operated within specified operating conditions. At the time of manufacture, a media test system evaluates every drive and identifies each media defect location. The defective areas are identified by head address (HD), cylinder address (CYL), and number of clocks from Index (CFI). The list of manufacturer-found defects is stored on the drive in a reserved, write-protected area accessible by the SCSI controller. This list is known as the MDL (Manufacturers Defect List) or PList (Primary Defect List). A printed listing of the defects is also shipped with each drive. The entries it contains can be mapped out (reassigned) automatically at format control parameter bits. Seek Time --------- ----------------------------------+--------+ Track-to-Track read msec. typ. | 1.5 | write msec. typ. | 2.5 | Average msec. typ. | 10 | msec. max. | 25 | Latency msec. avg. | 5.56 | ----------------------------------+--------+ Multi-Segment Read Ahead ------------------------ The Multi-Segment Read Ahead function partitions the 256K data buffer into multiple buffers or segments. The read-ahead function causes the drive to transfer the requested block into its buffer and continue to read sequential blocks until the buffer (or segment) is filled or another command is received. On subsequent request data, the buffer will be checked for the requested blocks. If the data already resides in the buffer, it will be transferred to the host and no media access will be necessary. This results in a significant improvement in performance. Internal Data Rate ------------------ 32 to 46 MHz Sector Size = Variable; programmable up to 4096 bytes.
