Figure
illustrates redundant IPT modules using two
NIMP01 termination modules. This configuration gives each
IPT module control of a termination module with two RS-232-C
serial channels. Only the primary IPT module can enable its
termination unit. The secondary IPT module will not enable its
termination unit unless it becomes the primary transfer mod-
ule.
