Fiber Optics Module (Item No. 7)

TM 5-6350-275-24&P

(g) Fiber Optics Module (Item No. 7). This module provides fiber optic interface between the PMC and the RADC.

(h) PMC Digital Multiplexer (Item No. 8). This is a PWA that configures the PMC for up to 256 RADCs, and to the

DES encoder/decoder PWA.

(i) Data Encryption System (DES) PWA (Optional) (Item No. 9). This PWA is connected to the multiplexer PWA

by a ribbon cable. The PWA receives data from the multiplexer, encodes the data, and transmits the encoded data

to a remote DES module located in the RADC. The DES PWA also receives encoded data from the remote module,

and decodes and sends the data to the multiplexer PWA.

(j) Laptop Computer (Item No. 10). The laptop computer is an 80386 processor used to enroll/program the remote

DES Module and the STARGATE PWAs located in the RADCS.

(k) Power Supply Module (Item No. 11). Translates line alternating current (ac) to +35 vdc, which is distributed to

each component in the system. The input voltage is 120/240 volts alternating current (vac) selectable.

(l) 9600 Baud Modem (Item No. 12). The 9600 baud modem processes serial digital data.

(m) Keyboard (Item No. 13). The keyboard is the international 112 key configuration. Layout of the keys is the U.S.

standard "QWERTY" format, with dedicated function keys, programmable function keys, cursor control keys, and a

numeric pad.

(n) Processing Unit (Item No. 14). Consists of:

1. PMC CPU. A compact, modularized information processing system with 16 megabytes of RAM. Also in the

processor module are the hard or fixed disk and the flexible (floppy) disk.

2. 150 Megabyte Tape Streamer. The 1/4 inch tape streamer module provides hard disk backup in one full

height 1/4 inch streaming tape drive.

3. Four-Port Data Communications Expansion Module. Provides the system with four bidirectional

communications ports. These ports are used for low speed data communications to peripherals such as the

modem.

(2) Operator Workstation (see Figure 1-5). Location and description of items.

(a) Operator Workstation with CPU (Item No. 1). A compact, modularized information processing system with 2

megabytes of RAM. The Workstation is connected to the Primary Monitor Console (PMC), Control Processing Unit

(CPU).

(b) Color Monitor (Item No. 2). The monitor is a 14 inch high resolution color display featuring a tilt and swivel base

and a non-glare, high contrast screen. The keyboard is attached to the monitor.

(c) Keyboard (Item No. 3). The keyboard is the international 112 key configuration. Layout of the keys is the U.S.

standard "QWERTY" format, with dedicated function keys, programmable function keys, cursor control keys, and a

numeric pad.

(d) Power Supply Module (Item No. 4). Translates line ac to +35 vdc, which is distributed to each component in

the system. The input voltage is 120/240 vac selectable.
