transceiver. If failover occurs, the secondary INIIT02 module
connects the antenna to the redundant transceiver.
Function
Code 202 - INFI-NET to INFI-NET Remote Transfer Module
Executive Block (INIIT02)
in the Function Code Application
Manual explains how to configure the executive block when
using redundant transceivers.
Voltage levels and polarities of enable signals to transceivers
and other communications equipment vary. Refer to the appli-
cable user manuals for the operating specifications of trans-
ceivers or other communication equipment before making any
connections to the IMDSO01, IMDSO02, IMDSO03 or
IMDSO04 Digital Slave Output Modules, or IMDSM05 Digital
Slave I/O Module.
Redundant Termination Units/Modules
Redundant configurations can be with or without redundant
termination units or modules. In both cases, one or both serial
ports can be used for data transfer depending on the needs of
the application. Figures
E-2 through E-5 show redundant
interfaces using various termination unit and module configu-
rations.
Figure E-2 illustrates redundant INIIT02 modules using a sin-
gle NTMP01 Multi-Function Processor Termination Unit. In
this configuration, the INIIT02 modules share a single termina-
