Those control units that are attached directly to the processor channels
include: • IBM 3272 Control Unit • IBM 3274 Control Unit, Model lB
The display stations and printers that are attached directly to the
control unit include: • IBM 3277 Display Station • IBM 3278 Display Station • IBM 3284 Printer • IBM 3286 Printer • IBM 3287 Printer • 3288 Printer • IBM 3289 Printer (will not attach to a 3272) The printers listed above are supported for the PFnn copy function
only. Part 1. Planning for System Generation 59

3270S The 3272 control unit can support the following devices: • IBM 3277 Display Station • IBM 3284 Printer • IBM 3286 Printer • IBM 3287 Printer • IBM 3288 Printer
The 3274 control unit, Kodel 1B can support the following devices: • IBM 3277 Display Station • IBM 3278 Display Station • IBM 3284 Printer • IBM 3286 Printer • IBM 3287 Printer • IBM 3288 Printer • IBM 3289 Printer Local Hardware Configurations Supported CONTROL UNITS The following control units are supported wben locally attached on a
byte multiplexer, block multiplexer, or selector channel to support 3270 devices: • IBK 3272 Control Unit Model 2 for attachment of up to 32 3277 Display
Stations Kodel 2, 3284 Printers Kodel 2, 3286 Printers Kodel 2, 3287
Printers, Models 1 and 2, and 3288 Line Printers Kodel 2. To support
this configuration, the following may be required:
--Device Adapter feature (13250) is required if more than four
devices are attached to the 3272. Up to four additional devices
can be attached with each device adapter.
--A 3271/3272 Attachment (18330) is required to attach each 3287
Printer. • IBK 3274 Control Unit Kodel 1B (supported as a 3272) for attachment
of up to 32 display stations and printers. All of the 32 devices can
be 3278 Display Stations Kodels 2, 3, and 41 (supported as 3211s),
3287 Printers Models 1 and 2 (supported as 3284s or 3286s), and 3289
Line Printers Models 1 and 2 (supported as 3288s). A maximum of 16
of the 32 devices can be 3271 Display Stations Model 2, 3284 Printers Model 2, 3286 Printers Model 2, 3287 Printers Kodels 1 and 2, and
3288 Line Printers Model 2. To support this configuration, the
following are required:
--The basic 3274 Control Unit permits attachment of up to 8 devices
(3278, 3287, and 3289). At least one 3278 is required.
--Each of Terminal Adapter Types Al, A2, and A3 (16901, 16902, and 16903) permits the attachment of up to 8 additional devices per
adapter (types 3278, 3287, and 3289). Only 1 of each type terminal
adapter is permitted. Terminal Adapter Type A1 is a prerequisite
to Type A2, and Type A2 is a prerequisite to Type A3.
tModels 3 and 4 are supported as Kodel 2 via hardware default. 60 IBM VPJ/370 Planning and System Generation Guide
