S-Registers
This appendix contains an explanation of each S-register used by the 8400B
Plus Data Module. There are a total of 28 S-registers. Twenty-two S-registers
are used to store configuration parameters, one is used to store installation
options, and the remaining five are unused. Eleven registers can be stored in
nonvolatile memory, which will be restored when the unit is powered up. There
are two sets of stored registers, or profiles. When the 8400B Plus Data Module
is first powered on, the values that were last stored in the S-registers are the
values in effect until AT commands are issued to change them.
You can check the current value stored in all S-registers with the &V command
(see the description on page A-28). The &V command displays all active and
stored configuration data as shown in Figure C-1 on page C-2.
