The optional Model AC1383 complete reference manual provides detailed information on setting up the 6B Series Subsystem. The manual includes complete specifications and the 6B Series Command Set. An included utility/demo software on a 3.5-inch software diskette enables a user to configure, calibrate, read data from or write data to the 6B Series modules and 6B50 I/O boards, without writing his own application programs. The 6B Series User Manual with software diskette must be ordered as a separate item.
