The 3174 Model 63R is a table-top remote controller that supports the IBM Cabling System interface for IBM Token-Ring Network attachment. The Model 63R supports up to sixteen 3270 devices and eight ASCII devices.

Terminal Attachment

The 3174 Establishment Controllers offer a wide variety of terminal attachments. They can be configured to connect terminals directly, via 3299 Terminal Multiplexers, via optional Terminal Multiplexer Adapters (#3103) and via optional Telephone Twisted Pair Terminal Multiplexer Adapters (#3105), or by a combination of these attachments.

Models 61R, 62R, 63R and 64R have a maximum attachment capability of 16 terminals. The base controller has an integrated nine-port terminal adapter which permits up to nine terminals to be directly attached, or by using one of the following, up to a maximum of 16 terminals can be attached:
