K1.2 FiberĆOptic Remote I/O Network System
Components
The AutoMax fiberĆoptic Remote I/O network system consists of the
following components:
D Drop Cable (M/N 57C366) Ć used only with the Remote I/O
Communications module or the Shark Interface module.
D BNC Tee Adapter (M/N 45C70), BNC Terminating Load
(M/N 45C71), and Balun Ć used only with the Remote I/O Head,
the Remote Drive Interface Head, or a personal computer
contianing a PC Link module.
D StandĆAlone FiberĆOptic Transceiver (M/N 57C365)
D FiberĆOptic Rack with Power Supply (M/N 57C368)
D RackĆMounted FiberĆOptic Transceiver (M/N 57C367)
D FiberĆOptic Cable
Each of these components is shown in figure K1.1 and described in
the sections that follow.
K1.2.1 Drop Cable
The drop cable (M/N 57C366) is used to connect the Remote I/O
Communications module or the Remote I/O Interface module to the
transceiver.
A 9Ćpin DĆshell connector is provided at one end of the 3Ćfoot
(1Ćmeter) cable for connection to the Network module. Terminations
are provided on the other end of the cable for connection to the
terminal strip on the transceiver. Refer to figures K2.2 and K2.4 for
these connections.
K1.2.2 BNC Tee Adapter and Balun
For the Remote I/O Head, the Remote Drive Interface Head, and the
PC Link module, a twistedĆpairĆtoĆcoax balun is used to convert the
cable between the module and the transceiver. The balun is
connected to the module via the BNC Tee Adapter (M/N 45C70).
Note that a 75 ohm terminating load (M/N 45C71) is required. The
balun is connected to the transceiver using twistedĆpair wire. See
section 3.1.4 for more information on the BNC Tee Adapter.
K1.2.3 StandĆAlone FiberĆOptic Transceiver
The StandĆAlone FiberĆOptic Transceiver (M/N 57C365) is required
at each slave network drop for connection to the fiberĆoptic network.
(A StandĆAlone Transceiver is required at the master rack only if the
rack cannot be located within 3 feet of the fiberĆoptic hub.) It
performs the biĆdirectional conversion between electrical and optical
signals. Transceiver technical specifications are listed in Appendix A.
The transceiver is designed to be panelĆmounted (vertically or
horizontally). Mounting holes are provided on flanges that extend
from both ends of the enclosure. See figure K1.2.
Receive and transmit ports labeled R" and T", respectively, are
provided on one end of the transceiver for connection to the 1
