Introduction; Site Requirements - Data General Dasher D461 User Manual

Introduction
This chapter covers all the steps required to install and check operation
of the 0411/0461 terminal. The information is organized as follows:
• Site requirements
• Repacking instructions
• Installation instructions
• Operational checkout instructions
• User maintenance
The installation and operational checkout instructions in this chapter
also include steps for terminal configurations that involve a printer, a
mouse, or a digitizer. Follow these instructions carefully.
Site Requirements
Your installation site for the 0411/0461 should meet the space,
environmental, power, and communication requirements defined in this
manual. (See specifications inside front cover.) If possible, locate the
terminal on a desk or table in a normal office environment with the
temperature at or near 24
0
C (75
0
F) and the relative humidity at or near
50 percent. Be sure that all terminal cables and power cords reach their
connection points, and that the ac power source matches the voltage
and frequency requirements of the terminal (and optional printer,
mouse, or digitizer). If you connect the terminal to a host computer
over telephone lines, install a terminal-compatible modem, or a current
loop or EIA cable from the host computer to the terminal site.
The selection of a communication line from the host computer to the
terminal depends on the cable length required, whether a modem is to
be used, and the configuration of the host system.
The 0411/0461 terminal permits use of an EIA RS-232-C as well as a
20-mA current loop and an EIA RS-422-A line.
