Alto 818 Installation and Operation
2-16 P/N 66109074001 Rev. D
2.3 TERMINAL, HOST AND PRINTER
A terminal with keyboard or a host computer must be used to control the Alto 818. Both may be
installed if desired. The use of a system printer is optional.
2.3.1 TERMINAL
WSE offers the SE 57101 terminal and keyboard, manufactured by Wyse, for user interface to
Alto 818 systems. The terminal is connected directly to the controller through the RS-232 port.
Other terminals which emulate a Hazeltine 1500 or Qume 101 may be used in place of the SE
57101.
2.3.2 HOST COMPUTER
Three host computers are available from WSE: SE 5850, SE 6000 and NexSentry Manager. A
single host computer may control multiple ACUs and provide additional capabilities. The Alto 818
connection to the host is through the RS-232 host or 20mA port on the ACU. See the appropriate
host manual for details.
2.3.3 PRINTER
The SE 57184 serial interface printer is available in two models: SE 57184-S1 for 115 VAC, 60
Hz and SE 57184-S2 for 230 VAC, 50 Hz operation. The printer may be connected to the host
port of the ACU, or act as a slave to a terminal or host.
