Turn mainframe power OFF. If you want to set a logical address other than
the factory-set address of 112, see "Setting the Logical Address Switch" to
set a different logical address for the multiplexer. Install the multiplexer
module in the mainframe. See "Installing the Multiplexer in a Mainframe"
for steps to install the multiplexer.
NOTE
If you have already connected user inputs to the terminal module, you may
want to disconnect the terminal module from the switch module for this
exercise. See "Attaching a Terminal Module to the Multiplexer" to
disconnect the terminal module.
Turn mainframe power ON and enter the following BASIC program into your
computer. For this program, the GPIB Select Code = 7, primary address =
09, and logical address = 112. The logical address divided by 8 = the
secondary address (112/8 = 14). Thus, the instrument address is 70914.

RUN the program. The response should be as follows. The device driver
revision must be A.08.00 or later.

This exercise performs close, open and scanning operations and queries
the status byte. Now that communication with the module has been
established, you can perform some close, open and scan operations and
use the "SCAN COMPLETE" bit in the Status Operation Event register
(bit 8).
Operation Event Register bit 8 designates scan complete when high.
Reading this register clears the register (all bits to zero). This bit is monitored
by serial polling (SPOLL) the status byte register (bit 7) in line 70. You may
want to look at the STATUS command in Chapter 4 which graphically shows
the relationship of these two bits and all status registers relating to this
module.
Input this BASIC program into your computer. Do not input the comments
preceeded by " ! ".
