Video Standards — All PC video up

to 1600 x 1280 non-interlaced

video; Monitor used must support

desired video resolution.

Supported CPUs — AT, PS/2

®

, IBM

®

PC 286, 386, 486, Pentium

®

or

compatible, and most PC-UNIX

boxes (SGI, RS6000, etc.)

Interfaces —

CPU and MONITOR/

KEYBOARD/MOUSE Ports:

Proprietary composite of:

• IBM AT or IBM PS/2

keyboard;

• RS-232 or PS/2 mouse;

and

• Video (standards listed

above);

RS-232 Port: Proprietary

variant of EIA RS-232D, DTE

Resolutions —

With original Serv cabling:

To 1024 x 768 noninterlaced;

With coaxial cabling:

To 1600 x 1280 noninterlaced

Protocol — RS-232: Asynchronous

Data Format —

RS-232: 8 data bits, 1 stop

bit, no parity (fixed)

Data Rate —

RS-232: 9600 bps or (for

Maximum Distance — Depending

on the CPU, monitor, and video

resolution, either:

• 7.6 m of total original

Serv cable from the

keyboard, monitor, and

mouse to any CPU,

including up to 1.5 m

from any ServSwitch to any

other Serv unit (submaster)

attached to it; or

• 6.1 m of coaxial

cable—possibly as much

as 30.5 m,

depending on CPUs—from

any ServSwitch to any

device attached to it;

Also, 15.2 m of serial

cable from any ServSwitch’s

RS-232 port to a non-local

computer (for switching via serial

port or upgrading firmware)

Specifications

• ServSwitch-to-ServSwitch

Cables (EHN274) for

cascading.

• A rackmount kit.

Additional Equipment You Might Need

• A keyboard and mouse. They

must both be of the same

platform—AT or PS/2.

• A monitor compatible with all

of the CPUs’ video cards,

capable of syncing to each

CPU’s video-output

frequencies. We recommend

that the monitor be able to

display a maximum resolution

of at least 1024 x 768 (1600 x

Additional Equipment You Will Need

1280 is better) at a maximum

refresh rate of not less than

75 Hz.

• A Monitor/Keyboard/ Mouse

(M/K/M) Adapter Cable to

connect the shared monitor,

keyboard, and mouse to the

ServSwitch.

• CPU Adapter Cables to

connect your CPUs to the

ServSwitch.

• An RS-232 cable and adapter

for remote switching.

• Station Extenders for extra

distance.

• ServSwitch unit.

• Power supply.

• User manual.
