wires that will be used to provide 120 VAC or 240 VAC
input power.
c.) Using 14 AWG wire, connect the input power wires to
terminals L1 and L2.
d.) Connect the jumper wire to the corresponding
terminal, either 120 or 240 volts.
e.) Slide the guard back to cover the terminal strip and
replace the screw.
Step 6. Set the drop number (1Ć7) of the Remote Drive Interface
Head using the thumbwheel switch on the faceplate.
The drop number setting is recognized only at power up
or after a self test function. Therefore, make sure each
drop on the network has a unique drop number before
power is applied. If more than one drop is given the same
drop number, transmission collisions will occur on the line.
The Remote Drive Interface Head 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 Drive Interface
Head's faceplate after power up. To clear the invalid drop
number fault code, refer to chapter 6.
Step 7. To connect the module to a fiberĆoptic network, go to step
9. If you are connecting the module to a coaxial cable
network, continue to step 8.
Step 8. Connect the BNC Tee Adapter from the Remote I/O
network to the BNC connector on the Remote Drive
Interface Head 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 3.23. 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 Appendix K and
connect the twisted pair wire to the transceiver. Continue
to step 10.
