2.0 SAFETY NOTES
•The LBN200 employs an infrared laser device that emits invisible light,
which can permanently damage the retina of an eye.
•Avoid direct exposure to the laser light source.
•Never apply power to this product if the fiber is neither connected nor
terminated.
•Never stare directly into a fiber or at any mirror-like surface that could
reflect light emitted from an un-terminated fiber.
•Never view an active fiber through optical instruments.

5.0 RF Connector Installation:
1. All RF connectors including the power port connector are standard KS-type connectors.
Refer to Figure 2.
2. Using a ½ inch (12mm ) wrench, remove port covers from RF ports and power port on the
housing base.
3. The center conductor seizure screws (Phillips screw) are located through the module.
Loosen, but do not remove the seizure screw.
4. Measure the stinger to verify that it is 1.0 inches (25mm). Refer to Figure 3.
5. If you are going to apply shrink tubing to weatherproof the finished connection, slip a section
of shrink tube over the end of the cable now.
6. Insert the KS connector and cable to the Housing base and tighten connector. KS connectors
should be tightened per manufacturer’s specifications.
7. Using a Philips screw driver tighten the seizure screw.
8. Position the shrink tubing over the connector and apply heat to shrink it in place.

1. The LBN200 can be powered either with 120VAC mains or HFC power supply with AC input
between 40 and 90 VAC. AC power is brought into the Node through the dedicated power port.
2. Follow “RF Connection Installation” section to install Power cable.
CAUTION! AC voltages in the range of 40 to 90 V AC. Shut down external AC power before
connecting or disconnecting power cables to the node.

7.0 AC Power Director:
1. AC HFC power can be sent to remote locations via the output ports by installing a plug in fuse bar.
Figure 4 has no Fuse bar, therefore does not pass power.
2. Check the system maps to determine which ports should pass power. Install each fuse bar as
required. Refer to Figure 5.
8.0 General Set-up:
1. Test the optical input power on the system downstream cable with an optical power meter to verify
that it is within the optical input range specification.
2. Clean the optical connector on the node and on the service cable and connect them together.
3. Verify that the total upstream RF signal level (from all ports) is within the node’s specified input range,
then connect the coaxial cable to the node’s RF In/Out port.
4. The LBN200 must be grounded, Use a split-bolt grounding stud or your system preferred ground
attachment to ground the Node housing to earth ground. Install the split-bolt grounding stud on the
base housing. Refer to Figure 6.
• For a strand-mounted node, install the grounding stud in the threaded hole on the base.
• For a pedestal or surface mounted node, remove one of the two strand mount brackets,
and install the grounding stud in the threaded hole.
Loosen the top nut and insert the grounding cable. (You may need to remove the nut to insert cable.
With the grounding cable installed, tighten the top nut to secure the cable.
5. Apply HFC power to the node through power port (40 –90VAC). Verify that the “Power LED” and the
“Opt. RX” LEDs illuminate.

9.0 Forward Path Set-up : (Refer to Figure 7)

User Manual
1. Using an optical power meter, measure the input optical power level at the fiber optic connector
coming into the node. The acceptable range is -8 to 0dBm.
2. Clean and install the incoming fiber connector to the forward bulkhead.
3. Using a DVM, measure and record the optical input power level at the electrical test point
(1V/mW). Verify optical input levels using Table 1.
4. Using a CATV Signal level Meter, verify the RF output levels at the -20dB test point on Output
1.
5. The Pad and Equalizer values are established by the use of JXP attenuators. The Equalizer
circuit is built on the board therefore choose a pad value to achieve your desired slope. (eg.
12dB attenuator in EQ2 will result in a 12dB output tilt between 54 and 1000MHz).
6. The LBN200 comes factory set with a 4dB pad in ATT1, 0dB pad in ATT2, and 12dB value in
EQ1 for optimum performance as per specifications. Verify and record your desired output level
and tilt. Attenuator values may be off ± 1db to slight tolerance difference between units. Use
Step 4 to verify output set up.
7. Plug in the desired Feeder Maker for the number of outputs required. Feeder Maker 100 is for
one output, 204 is for 2 outputs. While monitoring the forward Out1 test point (-20dB), with a
4db pad in ATT1 and with a 0dB pad in ATT2 position, place the pad value corresponding to the
desired output tilt into EQ2. Continuing to monitor Out1 test point (-20dB), adjust pad value in
ATT2 position for the desired output level. Verify that the level is correct at both ends of the
bandwidth spectrum. Output 1 & 2 are now set up in the Forward Path.
