JUMPER CONNECTIONS
A DLA1 unit is factory-equipped with a “lead-wire jumper
connection” across the Jumper Connection terminals in or-
der to close the circuit and thereby prevent transmission-
line waveform reflections.
• Twisted-pair Cable
With systems of 3 or more units, remove these jumper con-
nections from all units except those at the ends of a trans-
mission line.

• Fiber Optics
When installing systems with both fiber-optic and twisted-
pair transmission lines, treat each fiber-optic station as an
end-station and remove jumper connections only from units
inside twisted-pair cable loops.
