INSTALLATION AND OPERATION MANUAL
APPLICATION NOTES
1
Mixed PoE and Non-PoE systems can be implemented.
2
Lower data rates generally provide longer operating distances.

Extended Port Data Rate
Extended Distance

Distance figures are obtained using in-house testing mirroring installations. Factors such as coaxial/copper cable quality, the number of connectors/
1
splices in the cable run, the use of PoE, and environmental conditions encountered within the installation may affect the actual transmission
distance, and should be taken into consideration.

Steps to Take
Check that power is properly applied to the unit using the correct connector pair.
Check Ethernet Link LEDs, Extended Link LEDs, All Connections, Local/Remote switch is set properly.
Verify that Local units are installed at the head end and that Remote units are installed in the field.
Verify that the Data Rate switches are set to the same data rate on both the Local and Remote units.
Make sure Data Rate and 1/4 Pair Switches are set properly, and the extended distance is within specifications (see Table
3 – Approximate Maximum Extended Distances).
Check extended distance cable and connections. Try connection on a short cable to eliminate possibility of faulty cabling.
Check that the extended distance wire is connected to Extended Distance Port.
Verify that there is no additional equipment (e.g. surge protector) on the Extended Link. The cable should be continuous from
end to end, with no active components.
Check that the Managed/Unmanaged DIP switch is set to "Managed."
