OVERVIEW
There are two multi-function processor termination modules
(IMP). The NIMP01 Multi-Function Processor Termination
Module provides a connection to the serial interface for
multi-function processors
1
(MFP). The NIMP01 termination
module has two isolated RS-232-C ports. One port can be con-
figured as a non-isolated RS-485 port. Multi-function proces-
sor modules use the ports to communicate with computers,
printers and sequential events recorders. The NIMP01 termina-
tion module also provides the connection for a station serial
communication link. This link allows the MFP module to com-
municate with an IISAC01 Analog Control Station or NDCS03
Digital Control Station. Figure
shows a typical IMP termi-
nation module application.
The NIMP01 termination module also interfaces with the
INIIT02 INFI-NET to INFI-NET Transfer Module. The INFI-NET
to INFI-NET transfer module (IIT) supports bidirectional com-
munication through two RS-232-C ports. Port one passes sys-
tem data only. Port two passes system data or can be used as a
diagnostic port. The central IIT module can use a variety of
means to link to the satellite IIT module such as modems,
microwave and transceivers. This module communicates
directly with a network interface I/O module on the local
INFI-NET ring through the I/O expander bus.
The INFI-NET to computer transfer module
2
(ICT) provides the
electronics needed to direct the operation of the INFI-NET to
computer interface. It handles all communication with the host
computer through the multi-function processor interface (MPI)
or RS-232-C serial port. The MPI interface can act as DCE or
DTE equipment.
The NIMP02 termination module is used in addition to the
NIMP01 termination module when terminating redundant
modules.
INTENDED USER
Anyone who installs, uses and maintains the NIMP01 and
NIMP02 Multi-Function Processor Termination Modules should
read and understand this manual before placing the termina-
tion module into service. Installation and troubleshooting
require a technician or engineer with electrical experience and a
working knowledge of the RS-232-C and RS-485 standards.

When using an IMMFP03 Multi-Function Processor Module, the IMP termination module interfaces with the auxiliary I/O
card (IMMPI01 or IMMPI02 Multi-Function Processor Interface).
2.When using an INICT03 INFI-NET to Computer Transfer Module, the IMP termination module interfaces with the auxiliary I/
O card (IMMPI01 or IMMPI02 Multi-Function Processor Interface).
