The Ge-400/600 Series Peripheral Switch; Parallel Channel Adapt - GE DATANET-30 System Manual

THE GE-400/600 SERIES PERIPHERAL SWITCH. The peripheral switch subsystem (PSC 200) can
be used with a GE-400/600 Series and DATANET-30 computer system.
One peripheral at a time would be switched to the CPC 930 of the DATANET-30. For additional
information refer to the manual on this equipment.
Parallel Channel Adapter
The Parallel Channel Adapter is a manual switch used to switch communication lines from one
DATANET-30 to another or to connect two DATANET-30' sin parallel to the same line at the same
time.

The Parallel Channel Adapter (PCA) can be used with bit buffers or character buffers, and is
available in 2 models. PCA 930 is a single line switch used with buffers and Dataphone Dataset
Model 103 A or F digital subsets, or character buffers and Dataphone Dataset 202 C or D.
PCA 931 is a ten line switch used with buffers and voltage current adapters (line relay). Ten
switches are provided so that any one, all, or any combination of circuits can be switched from
either DATANET-30 to the other or operate in parallel.
