controllers to be switched.
A complete peripheral switch control subsystem consists of one
switch control console and eight peripheral switch units. A minimum subsystem consists of a
control console and one switch unit.
CONSOLE UNIT. The switch control console performs two functions: (1) assigns each controller
selector to the desired central processor and (2) assigns the selected priority channel to each I/0
device.
The console is the control center of the peripheral switching subsystem. All controls
necessary for the switching operation, and the interconnections for each of the peripheral switch
units and the two central processors, are contained within the switch control console.
SWITCH UNITS. The switch unit contains switching relays. The unit is mounted inside the periph-
eral controller.
Two standard priority control connectors on the switch unit connect to each of
the central processors.
Other connectors connect to the switch control console. Any com-
bination of one or more peripheral controllers may be connected to the peripheral switch control
console, limited only by any specific assignment characteristic of input/output devices on the
controller selector.
Additional information is contained in the manual for the Compatibles 200 Peripheral Switch
Control Subsystem.
PROGRAMMED PERIPHERAL SWITCH
The Programmed Peripheral Switch (PS-6010) is a modular, free-standing, program-controlled
switch.
It
is used to connect either of two processors to a single peripheral controller. Each
processor may be a GE-400 Series centralprocessor, a GE-600 Series Processor, or a DATANET-
30. A typical application of the PS-6010 switch is shown in Figure 30. For additional information,
refer to the manual on this equipment.
