Built–In Interfaces

System Unit Interfaces

The system board’s built–in interfaces have ports on the workstation rear panel.

Audio Interfaces

The J Class workstations have audio input and output capability through external input and output

connectorsontherearpanelandthroughaninternalspeaker.TherearpanelcontainstheAudioIN(Stereo

line–in) and Mic (Mic–in), and Audio OUT (Stereo line–out) and Headphones (Headphone–out)

connectors.

The audio connectors are standard stereo audio mini–jacks. Hewlett–Packard recommends using

gold–plated plugs available through audio retailers for best quality recording and playback through the

external connectors. The following is a summary of the workstation audio features:

•Audio Features Programmable sample rates:

8kHz, 16kHz, 32kHz, 48kHz, 11.025kHz, 22.05kHz, and 44.1kHz.

Programmable output attenuation:

0 to –96dB in –1.5dB steps

Programmable input gain:

0 to 22.5dB in 1.5dB steps.

Input monitoring:

16–bit linear, 8–bit u–law, or A–law coding

•Audio Inputs Line–in

Mono microphone compatible with 1.5V phantom supply

(bias voltage supplied by the system)

CD–ROM audio (if internal CD–ROM is installed)

Keyboard Interfaces

The J Class workstation provides keyboard interfaces that allow either PS/2 or ITF keyboards. Consult

the documentation that accompanies each input device for specific information concerning its use.

PS/2 Keyboard Interfaces

The PS/2 connectors provide an interface for the keyboard and mouse to the system.

ITF Keyboard Interface

The HP HIL connector provides an interface for the ITF Keyboard to the system and all HP HIL devices.

HP Parallel I/O Interface

The 25–pin HP Parallel I/O interface uses Centronics interface protocols to support peripheral devices

such as printers and plotters. Consult the documentation that accompanies each peripheral device for

specific information concerning its use.

1-6 General Information J Class Technical Reference

Network Interface

The J Class has built–in ThickNet LAN AUI and TP (Twisted Pair) connectors for the 802.3

(ETHERNET) network. Connections to ThinLAN networks require an external transceiver. Your

workstation will autoselect the correct network setting.

The IEEE 802.3 Ethernet Local Area Network (LAN) circuit provides both the AUI interface for

conventionalcoaxial Ethernetand adirect interfaceto atwisted pair(TP) 10BASE–Tnetwork. Only one

built–in interface can be used at a time. The system auto–selects the correct port that is being used.

Ethernet is a 10 Mbit/s packet–switched serial interface employing Carrier Sense Multiple

Access/CollisionDetection(CSMA/CD). Table 1–3liststhesupportedLAN adaptersand othernetwork

devices.

HP 28673A 10:10 LAN Bridge

HP 28683A Fiber Optic Transceiver

RS–232 Serial I/O Interfaces

The RS–232 Serial I/O (SIO) ports on the J Class accept a variety of pointing devices or peripheral

devices. Peripheral devices include printers, plotters, modems, and scanners. Consult the documentation

that accompanies each peripheral device for specific information concerning its use.

The SIO ports are programmable, allowing the setting of such functions as bit rate, character length,

parity, and stop bits. SIO Ports are used as interfaces for serial asynchronous devices to the CPU. The

ports operate at up to a 19.2 K baud rate.

Table 1–4 shows the SIO connector pin listings. The serial connectors are 9–pin D–sub connectors.

Signal names are those specified in the EIA RS–232 standard.

Use the SCSI connectors to connect external SCSI devices such as DDS–format tape drives and

CD–ROM drives. Consult the documentation that accompanies each SCSI device for specific

information concerning its use. Refer to Appendix C of the J Class Owner’s Guide for information about

connecting SCSI devices to the workstation.

Function Data

Type: SCSI–II (ANSI X3.131–1986), single–ended

Data rate: Synchronous – 5 MBs/second

Device limits: 7 internal and/or external peripherals

Connector type: SCSI–II, ALT–1 50–pin high–density thumb-

Single–Ended SCSI–2

The built–in SCSI–2 port is implemented using an NCR710 macrocell inside the I/O ASIC chip. This

8–bit single–ended implementation is synchronous and compatible with the current 700 series products

and supports 5 MB/sec data transfer rates.

The SCSI bus is terminated to 3.3 volts through 127kΩon the CPU board. If an external disk drive is

used, an active terminator must be used on the drive at the end of the cable.

Fast, Wide Differential SCSI–3

Fast, wide SCSI is an extension to the existing 8–bit, single–ended SCSI. “Fast differential” indicates

thatsignals onthe SCSIbusaredifferentiallydrivenand terminated,andcapableof a10 MHzclock rate.

“Wide” indicates that there are 16 data bits on the SCSI bus.

Thefast,wideSCSIbusisspecified atapeaksynchronoustransferrateof 20MB/sec. Thearchitectureof

the fast, wide SCSI port on the J Class workstation has been designed to allow a 20 MB/sec sustained

transfer rate for long data streams.

Power Cord Connector

Plug the workstation’s power cord into the power cord connector to provide ac power to the system.

Hardware Architecture

The J Class is a mid–tower style designed to be easy to operate and upgrade. The features in this package

aredesigned for useraccess tothemajority ofthesystem’supgradable parts (disks,memory SIMMs, and

processors) without moving the system.

Figure 1–1 shows the front view of the system. There is a Power Switch with an LED to indicate that the

system is on/off, and an LCD panel that informs users of the system’s status. In the case of a failure, the

LCD indicates the failure code.
