3-3 LR Area Division Tables

The PC Link Unit has the ability to transfer from 2 to 32 words (32 to 512

bits) of data between PCs. The LR area is divided according to the number of

PC Link Units and the number of Subsystems in the System. Refer to the

appropriate table for your System. Any unused portion of the LR area may be

used as work bits. The number of LR bits transferred per Unit and Single-le-

vel/Multilevel designation are made on switches on the PC Link Units.
