Connections to the Station Transponder Unit
Figure 40: Model 6203 Bottom Plate
Power Connections
The power connection for the Station Transponder Unit is routed through a large hole in
the center rear of the bottom side of the unit. The hole in the case is sized to accept a
standard electrical conduit coupler (1.2 inches). Inside the unit is a reversible plate that has
a large hole (0.875 inches) in one end to support a second size of conduit coupler and a
smaller hole (0.5 inches) to accept a line cord with strain relief. The coaxial connector of
the DC power supply is routed through this central hole.
An uninterruptible power supply (UPS) is recommended for station units.

Connecting DC Power to the Station Transponder Unit
1. Feed the coaxial connector of the DC power supply through the opening in the
bottom of the unit and through the 1/4-inch clamp. The clamp provides strain relief
and cable routing.
2. Connect the DC power supply male coaxial connector to the female coaxial
connector on J1 .
3. [Optional] If needed, mount the Power Supply Wall-Mount Bracket (415-0642) to
a convenient location and place the DC power supply in the bracket. This bracket
can help provide strain relief between the Model 6 and the power supply, or to keep
the power supply up off of the floor. Use the provided hook and loop tape to secure
the power supply to the bracket. This prevents the power supply from falling out
during an event such as an earthquake.
4. When the Station Transponder Unit is ready to be powered, connect the DC power
supply to a suitable AC source.
