INTENDED USER
Anyone who installs, operates or performs maintenance on the
INFI-NET to INFI-NET interfaces should read this manual
before placing an interface into service. Installation requires an
engineer or technician with experience handling electronic cir
cuitry and who is familiar with communication networks.
INTERFACE DESCRIPTION
The INFI-NET to INFI-NET interfaces are the INIIR01 INFI-NET
to INFI-NET Remote Interface and the INIIL02 INFI-NET to
INFI-NET Local Interface. The INNIS01 Network Interface Slave
Module is the front end of the INFI-NET to INFI-NET interfaces.
It is the intelligent link between a node and the INFI-NET loop.
The network interface slave (NIS) module and an INFI-NET to
INFI-NET transfer module create a specific node interface.
The INIIR01 INFI-NET to INFI-NET Remote Interface is made
up of the NIS module and the INIIT12 INFI-NET to INFI-NET
Transfer Module. This interface is a node on a central loop that
can communicate to an interface node on a remote satellite
loop (two interfaces are required, refer to Figure 1-1). Bidirec
tional communication from the central loop to the remote sat
ellite loop is through standard RS-232-C ports. The INFI-NET
to INFI-NET remote interface can support hardware redun
dancy. Refer to Appendix E for information on hardware
redundancy.
