1-11. EQUIPMENT PURPOSE, CAPABILITIES AND FEATURES

The 600GR converter consists of a 19-inch equipment rack which contains 12

individual converter boards, each with its own power supply. Each converter board

consists of a transmit and receive section. The transmit section generates a dc

level carrier signal which is sent to the receive section of an identical converter

board at the other end of the communications line. The transmit section also

accepts digital data from a computer or data processing terminal. Each converter

board converts this digital data from the terminal into bipolar dc level pulses

which are suitable for transmission over metallic wire. An identical converter

board at a remote receiving location translates these pulses back to digital form.

The converter can:

Receive and transmit data at rates up to 9600 bps between your ADP system

and other ADP system(s) or remote terminal(s). Transmission must be over

unloaded telephone metallic lines or dedicated metallic circuits up to 2

km in distance

Operate point-to-point, four-wire, full or half duplex mode

Provide fault isolation during checkout and installation using front panel

diagnostic LEDs and loopback test switch

Help you monitor operation of each individual power supply by lighting

power LED indicator on the front panel of each converter board

1-12. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS

Major operating components (fig. 1-1 ) are located at the front of the converter

assembly. Ac power is provided by an ac power cord with grounded three-wire plug,

The ac line is fused at the rear of the unit. When power is on, lighted indicators

show the operating status of each converter board.
