The front panel contains two RS-232C communication ports, the program-
mer's START/STOP switch, a unit number selector, and several indicator
LEDs. The back panel contains two sets of DIP switches for setting ASCII
Unit parameters and the PC Backplane connector.
The front panel of the ASCII Unit contains two RS-232C ports. These ports
are used for connecting peripheral I/O devices to the ASCII Unit. Both ports
can be used for communication devices such as printers, terminals, and mo-
dems. However, only port 1 can be used for uploading or downloading a BA-
SIC program. The standard configuration is to connect a personal computer
to port 1 and a printer or other I/O device to port 2.
The START/STOP switch is a toggle switch that is used for initiating and halt-
ing execution of the ASCII Unit program.
The Machine No. switch is used for identifying the particular ASCII Unit.
Since it is possible to have more then one ASCII Unit connected to a given
PC, the Machine No. identifies each individual ASCII Unit. It is not permitted
to have two ASCII Units with the same Machine No. The Machine No. can be
set from 1 through 9. This should be done before power is applied to the
Unit.
There are four indicator lights on the front panel. They are described in the
table following the diagram on the next page.
