Parallel I/O Adapter
The 5110 Parallel I/O Adapter allows you to attach IEEE 488-1975 compatible
devices to the 5110. The 5110 is the only active controller on the parallel
input/ output bus. Devices that you can attach include equipment such as
laboratory instruments, plotters, and printers.
You control a parallel input/output device with device-dependent messages
using the APL or BASIC language; this is similar to sending to and receiving
from the other 5110 input/output devices. Device-dependent message are
exchanged in either 8-bit binary code or 7-bit ASCII code according to the
IEEE 488-1975 standard.
Audible Alarm
You can use the Audible Alarm feature for many purposes; for example, to
indicate an error, to request operator action (such as changing printer forms or
changing diskettes)' or to alert the operator that a job is complete.
Channel Terminator
The channel terminator is required when you connect an auxiliary tape unit
and/or diskette unit to the 5110 and you do not also connect the 5103 Printer.
