The Remote I/OHead can be used only as a slave drop
(drop numbers 1Ć7, inclusive). Switch settings 0, 8 and 9
are invalid. If the thumbwheel switch is set to an invalid
drop number, error code A" will be displayed on the
sevenĆsegment LED on the Remote I/OHead's faceplate
after power up. To clear the invalid drop number fault
code, refer to chapter 6.
Step 7. If you are connecting the module to fiberĆoptic network, go
to step 9. If you are connecting the module to a coaxial
cable network, continue to step 8.
Step 8. To connect the module to the coaxial cable network,
connect the BNC Tee Adapter from the Remote I/O
network to the BNC connector on the Remote I/OHead
faceplate. Continue to step 10.
Step 9. To connect the module to a fiberĆoptic network, a
twistedĆpairĆtoĆcoax balun (AMP 555053Ć1 is
recommended) is used to convert the cable between the
module and the transceiver as shown in figure 3.22. The
balun is connected to the module via the BNC Tee
Adapter. Note that a 75 ohm terminating load (M/N 45C71)
is required. Refer to figure K2.2 in Apendix K and connect
the twisted pair wire to the transceiver. Continue to
step 10.

Step 10. Connect the rail ports using a Rail I/OInterconnect Cable
(M/N 45C5), which is provided with the analog and digital
rails. If you are using the Ready Relay, see section 3.5.5
for connection information.
Step 11. Turn on power to the Remote I/OHead.
Step 12. Verify the installation by connecting the programming
terminal to the system and running the AutoMax
Programming software.
Stop all application programs that may be running.
Use the I/O MONITOR function. Enter the slot number of
the master Remote I/Omodule, the remote I/Odrop
number (1Ć7), and the port number (0Ć3) of the Local Head
or rail. Enter the data register (0Ć3 for a Local Head, 0 for a
rail) to be monitored. The value displayed should reflect
the status of the register. Toggle an input or output and
verify that its status is reflected correctly in the register.
