tion unit and communicate through one or two serial channels.
The primary INIIT02 module controls the termination unit.
Figure E-3 shows redundant INIIT02 modules using NIMP01
and NIMP02 Multi-Function Processor Termination Modules.
This configuration gives redundant INIIT02 modules access to
the two RS-232-C channels on the NIMP01 termination mod-
ule. The secondary INIIT02 module must access the serial
channels on the NIMP01 termination module through its con-
nection to the NIMP02 termination module. The primary
INIIT02 module controls the NIMP01 termination module.
Figure E-4 illustrates how redundant INIIT02 modules use two
NTMP01 termination units. This configuration gives each
INIIT02 module control of a termination unit with two
RS-232-C serial channels. Only the primary INIIT02 module
will enable its termination unit. The secondary INIIT02 module
will not attempt to enable its termination unit unless it
becomes the primary transfer module.
Figure E-5 illustrates redundant INIIT02 modules using two
NIMP01 termination modules. This configuration gives each
INIIT02 module control of a termination module with two
RS-232-C serial channels. Only the primary module can
enable its termination unit. The secondary INIIT02 module will
not enable its termination unit unless it becomes the primary
transfer module.
