Recommended orientation is vertical on either side, or horizontal with the Device Electronics board down; other mounting orientations may be used provided the ambient air temperature around the drive is kept at or below 50*C (122*F). Mounting Screws --------------- 2 per side 6-32 UNC-2B x 0.156 max deep. 4 on bottom 6-32 UNC-2B x 0.20 max deep. Caution: The mounting screws must be selected so that they do not penetrate the bottom mounting holes more than 0.20 inches and the side mounting holes 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. Signal Connector J1 ------------------- J1 is a 50-pin connector on the Device Electronics board. Signal interface connection is made via this connector. The signals on J1 include the 8-bit SCSI bus and various control and handshaking lines. Recommended Cable: 3M Scotchflex 3365/50 or equivalent Mating Connector: 3M P/N 3425-3000 or equivalent Multi-Function Connector J2 --------------------------- J2 is a 24-pin connector on the Device Electronics board and is used for connecting the drive to a user-supplied Operator Panel. Power Connector J3 ------------------ J3 is a 4-pin keyed AMP MATE-N-LOCK connector on the Device Electronics board. Both +5V and +12V is supplied to the drive via this connector. Suggested wire size is 18 AWG. Recommended mating connector is AMP 1-480424-0 or equivalent. Recommended pins are AMP 350078-4. Ground Connectors J4/J5 ----------------------- 3/16-inch spade lugs J4 and J5 are provided for grounding. Systems characteristics determine proper ground connection. Mating Connector: AMP 60972-2 or equivalent Mating connector: AMP 60972-2 or equivalent. Interface Terminator -------------------- Interface Terminator pack RN9 provides proper termination for the interface lines. In multiple-device systems, the terminators are installed in the LAST device on the cable.

SINGLE-ENDED Interface Electrical Characteristics ------------------------------------------------- Interface control and status signals are digital (open collector TTL) using industry-standard transmitters and receivers. The assigned signals are terminated with 220 ohms to +5V (nominal) and 330 ohms to ground at each end of the cable. 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 1) Signal true = 0.0 VDC to 0.8 VDC 2) Maximum total input load = -0.4 milliamps at 0.5 VDC 3) Signal false = 2.0 VDC to 5.25 VDC 4) Minimum input hysteresis = 0.2 VDC b. Output Characteristics Each driven signal has the following characteristics when measured at the interface connector. 1) Signal assertion = 0.0 VDC to 0.5 VDC 2) Minimum driver output capability = 48 milliamps (sinking) at 0.5 VDC. 3) Signal negation = 2.5 VDC to 5.25 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. ********************************************************************** F E A T U R E S ********************************************************************** MICROPL. 1598/D PRODUCT DESCRIPTION 104979 REV.
